ESG STRATEGY: A Global Comparative Analysis: Regulatory Frameworks, Sectoral Dynamics, and the Strategic Imperatives for 2026

An ESG strategy is an organisation’s structured approach to govern, identify, prioritise, and manage environmental, social, and governance issues that affect enterprise value and risk — and, increasingly, to also manage and disclose outward impacts on people and the environment. This dual “inside-out” and “outside-in” framing is no longer aspirational language: it is codified in law across multiple jurisdictions, embedded in supervisory expectations for financial institutions, and demanded by capital markets.

Across the six jurisdictions examined in this report — the European Union, United Kingdom, Switzerland, United States, China, and Vietnam — ESG regulation has converged around a shared disclosure architecture (governance, strategy, risk management, metrics and targets) popularised by TCFD and now embedded into IFRS S1/S2. However, the substance, scope, enforcement intensity, and underlying materiality doctrine differ sharply between markets. Understanding those differences is essential for any organisation operating globally.

This report provides a jurisdiction-by-jurisdiction regulatory overview, a cross-jurisdictional comparison of commonalities and divergences, sector-specific analysis for financial institutions and enterprises, and a dedicated assessment of SME implications. It draws on primary regulatory texts, supervisory guidance, and institutional practice as of March 2026.

Key finding: Two materiality doctrines, one global baseline

The most consequential cross-jurisdictional divergence is materiality. The EU (via ESRS/CSRD) formalises double materiality — requiring disclosure of both how ESG matters affect the company and how the company affects the world. ISSB-derived regimes (adopted or in development in the UK, China, Switzerland, and others) emphasise investor-focused, enterprise-value materiality. Both models converge, however, on the TCFD structural architecture and the GHG Protocol measurement baseline. In practice, most global organisations now build one ESG strategy capable of satisfying both lenses.

What is an ESG strategy?

Definition: An ESG strategy is a governance-anchored plan that integrates material sustainability-related risks, opportunities, and — where required or strategically chosen — impacts into business decision-making, capital allocation, stakeholder engagement, and disclosure, supported by measurable targets and controls.

ESG strategies evolved from voluntary corporate social responsibility initiatives in the early 2000s into legally required frameworks embedded in capital markets regulation. The catalysts were threefold: the Paris Agreement (2015) establishing climate as a systemic financial risk; the Task Force on Climate-related Financial Disclosures (TCFD, 2017) providing a universal governance–strategy–risk–metrics architecture; and the parallel development of investor stewardship codes that elevated ESG from screening criteria to fiduciary duty.

By 2026, an ESG strategy is no longer a compliance exercise performed in isolation from the business. Regulatory frameworks across all six jurisdictions in this analysis now require or strongly expect that ESG be integrated into board governance, risk management systems, capital allocation processes, and external financial reporting.

Core components

Regardless of jurisdiction, a robust ESG strategy is built on five interconnected pillars:

The two materiality doctrines that drive divergence

Enterprise-value materiality (investor-focused): Anchored in IFRS S1/S2 and adopted or in development in the UK, China, the US (where it exists), and other ISSB-aligned jurisdictions. The test is whether a sustainability-related risk or opportunity could reasonably be expected to affect the entity’s cash flows, access to finance, or cost of capital. The audience is primarily investors and capital market participants.

Double materiality (impact + financial): Required by the EU’s CSRD/ESRS and adopted in principle by Switzerland. Companies must assess both financial materiality (outside-in: how ESG topics affect the company) and impact materiality (inside-out: how the company’s activities affect people and the environment). Both dimensions must be reported if material; neither automatically takes precedence.

Note: The EU’s Omnibus I (February 2026) retains double materiality as the foundational principle while narrowing the scope of companies required to report and directing a simplification of ESRS datapoints. The logic endures; the burden is reduced.

Jurisdiction-by-jurisdiction regulatory overview

European Union

---

The EU remains the most prescriptive and comprehensive ESG regulatory architecture globally. Three interlocking frameworks define the landscape: the Corporate Sustainability Reporting Directive (CSRD), the Corporate Sustainability Due Diligence Directive (CSDDD), and the Sustainable Finance Disclosure Regulation (SFDR), all underpinned by the EU Taxonomy.

CSRD and ESRS

The CSRD replaced the Non-Financial Reporting Directive (NFRD) and dramatically expanded mandatory sustainability reporting. Companies must report under the European Sustainability Reporting Standards (ESRS), which cover climate, pollution, water, biodiversity, circularity, workforce, value-chain workers, affected communities, and business conduct. The defining feature is double materiality: organisations must conduct a formal materiality assessment through both the financial impact lens and the impact on society and environment lens.

Omnibus I (February 2026) materially changed the architecture by: raising reporting thresholds to focus on companies with more than 1,000 employees and more than €450 million net turnover; excluding listed SMEs; capping value-chain data requests on firms below 1,000 employees; and directing the European Commission to revise ESRS within six months of entry into force to remove lesser-priority datapoints and strengthen materiality guidance. The EU’s overall sustainability disclosure architecture — ESRS, an assurance trajectory, and digitalisation — is preserved, but the universe of directly in-scope companies is significantly narrowed.

CSDDD

The Corporate Sustainability Due Diligence Directive introduces mandatory human rights and environmental due diligence obligations across the value chain. Following Omnibus I adjustments, the thresholds focus on companies with more than 5,000 employees and more than €1.5 billion in global turnover. Affected companies must identify, prevent, mitigate, and account for adverse human rights and environmental impacts across their upstream and downstream value chains — not only report on them.

SFDR reform

The Sustainable Finance Disclosure Regulation — which created the Article 6, 8, and 9 product classification system — is under active reform following the European Commission’s 2025 review. The review acknowledged complexity, investor confusion, and de facto labelling behaviour. The Commission proposed replacing the existing framework with a simplified product categorisation (“Sustainable”, “Transition”, and “ESG Basics” labels), aiming to reduce greenwashing risk while maintaining investor transparency. Reform is ongoing; the existing framework continues to apply.

EU Taxonomy and CBAM

The EU Taxonomy Regulation provides a classification system for environmentally sustainable economic activities across six environmental objectives. For in-scope companies and financial institutions, taxonomy alignment KPIs — taxonomy-eligible and taxonomy-aligned turnover, CapEx, and OpEx — are mandatory disclosures. The Taxonomy is a foundational differentiation between the EU and every other jurisdiction reviewed in this report.

From 1 January 2026, the Carbon Border Adjustment Mechanism (CBAM) moved from reporting-only to substantive payment obligations. Importers of carbon-intensive goods (iron, steel, cement, aluminium, fertilisers, electricity, and hydrogen) into the EU must now pay a carbon price equivalent to the EU Emissions Trading System (ETS). This mechanism has direct consequences for companies and financial institutions globally: exporters to the EU that cannot demonstrate carbon intensity alignment with EU standards face higher costs and potential loss of market access.

United Kingdom

---

Post-Brexit, the UK pursued a distinct path anchored in investor-focused financial materiality rather than double materiality. The regulatory architecture is characterised by TCFD-aligned corporate disclosure obligations, a labelling-focused investment product regime (SDR), and a discontinued green taxonomy project.

Corporate disclosure: TCFD-aligned rules and UK SRS

Large UK companies and limited liability partnerships (LLPs) meeting statutory thresholds, as well as listed issuers, are required to make TCFD-aligned disclosures on governance, strategy, risk management, and metrics and targets. These obligations are embedded in company law and FCA listing rules. In February 2026, the UK government published UK Sustainability Reporting Standards (UK SRS), which are ISSB-aligned (based on IFRS S1/S2). As of the publication date, the UK SRS are available for voluntary use; effective mandatory dates must be set through future legislation or regulation.

Financial sector: SDR, FCA climate rules, and PRA expectations

The FCA’s Sustainability Disclosure Requirements (SDR) regime introduces four specific sustainability labels — Sustainability Focus, Sustainability Improvers, Sustainability Impact, and Sustainability Mixed Goals — for investment products marketed to retail consumers. The regime requires that at least 70% of a labelled fund’s assets be invested in accordance with a robust, evidence-based sustainability standard.

Underpinning the SDR is the Anti-Greenwashing Rule (effective May 2024), which requires all FCA-authorised firms to ensure any references to sustainability features are clear, fair, and not misleading. This applies to all sustainability-related claims, not only labelled products.

The FCA also mandates climate-related disclosures for asset managers, life insurers, and regulated pension providers (PS21/24). The Prudential Regulation Authority (PRA) has published detailed supervisory expectations (SS3/19, updated 2024) requiring banks and insurers to embed climate risk into governance, risk management, scenario analysis, and capital management — proportionate to the scale and complexity of their business.

Green taxonomy: discontinued

In July 2025, the UK government confirmed it would not proceed with a mandatory green taxonomy. The UK instead relies on disclosure obligations, the SDR labelling framework, and the anti-greenwashing rule to support market integrity in sustainable finance — a markedly different approach from the EU.

Switzerland

---

Switzerland’s approach to ESG regulation combines corporate law obligations, climate-focused disclosure requirements based on TCFD, and a strong market-based sustainable finance ecosystem. Its strategy is deliberately interoperable with EU frameworks — a pragmatic necessity given the depth of economic integration — while maintaining its own distinct legal architecture.

Non-financial reporting and climate ordinance

Under the Swiss Code of Obligations (CO), large public-interest entities meeting employee and financial thresholds must publish a non-financial report covering environmental, social, employee, and human rights matters. The Ordinance on Climate Disclosures (effective 1 January 2024) extends these obligations by requiring large companies, banks, and insurers to report on climate-related risks using TCFD pillars, including scenario analysis. Enforcement includes potential criminal fines for non-compliance — one of the strongest enforcement signals among the jurisdictions reviewed.

In 2025, Switzerland temporarily paused planned revisions to its climate reporting rules pending clarity on the EU’s Omnibus process. This reflects the deliberate interoperability strategy: Swiss firms are predominantly subject to EU market and supply chain expectations, and unnecessary divergence from the EU architecture would impose additional compliance costs.

Climate and Innovation Act

Approved by referendum in 2023, the Climate and Innovation Act legally binds Switzerland to net-zero emissions by 2050. The Act allocates CHF 3.2 billion over ten years to support companies in adopting low-carbon technologies, including carbon capture and storage. Financial institutions are expected to align their investment and lending activities with these national climate targets.

FINMA and sustainable finance

FINMA (the Swiss Financial Market Supervisory Authority) published Guidance 01/2023 on climate risk, setting supervisory expectations for financial institutions regarding climate-related governance, risk management, and disclosure. The Swiss Bankers Association has developed industry guidance explicitly framing climate reporting as a double materiality exercise. Swiss Climate Scores provide a standardised transparency tool for the climate-related characteristics of financial investments.

United States

---

The United States presents the sharpest contrast to the EU model: a fragmented, politically contested, and uncertain ESG regulatory environment at the federal level, partially offset by significant sub-national mandates and persistent investor-driven demand for ESG data.

Federal landscape: SEC rule stayed and undefended

The SEC adopted climate disclosure rules in March 2024 (Release No. 33-11275), which would have required SEC registrants to disclose material climate-related risks, governance, and (for large accelerated filers where material) Scope 1 and 2 emissions with attestation requirements. The rules were immediately subject to legal challenges consolidated in the Eighth Circuit; the SEC voluntarily stayed their effectiveness. In March 2025, the SEC voted to end its legal defence of the rules. As of March 2026, the rules are stayed, undefended, and unlikely to take effect in their current form. US federal corporate climate disclosure obligations therefore remain governed by general securities-law materiality and voluntary frameworks.

The second Trump administration has pursued an actively deregulatory agenda on ESG: revoking Biden-era executive orders, deprioritising climate-related rulemaking, and encouraging federal agencies to withdraw ESG-related guidance. Federal financial regulators (OCC, Federal Reserve, FDIC) have scaled back or reversed climate-related prudential guidance issued in 2022–2023.

California: sub-national leadership

California has emerged as the de facto national standard-setter for corporate climate disclosure. The Climate Corporate Data Accountability Act (SB 253) requires companies with more than \$1 billion in revenue doing business in California to disclose Scope 1, 2, and 3 greenhouse gas emissions — a scope requirement more stringent than the original SEC rule. SB 261 requires climate-related financial risk reporting aligned with TCFD. SB 219 (signed 2024) extended and refined these obligations. Given California’s economic scale, thousands of US and global companies are functionally required to comply.

Investor and market demand

Despite the federal rollback, institutional investors — particularly non-US institutions — continue to demand ESG data for risk modelling and stewardship purposes. TCFD and ISSB voluntary adoption among US-listed companies remains significant. Major US financial institutions (JP Morgan, Goldman Sachs, BlackRock) continue to publish structured climate and ESG data, driven by investor expectations, international regulatory requirements affecting their global operations, and internal risk management practices.

China

---

China’s ESG regulatory trajectory is one of the most consequential globally, driven by national climate commitments, a rapidly formalising disclosure architecture, and the world’s largest national carbon trading system. Unlike the EU’s investor-protection and impact-based model or the US’s fragmented voluntary market, China’s approach is state-directed and integrated with national economic planning.

Stock exchange sustainability reporting guidelines

The Shanghai Stock Exchange (SSE), Beijing Stock Exchange (BSE), and Shenzhen Stock Exchange (SZSE) published mandatory sustainability reporting guidelines in April 2024, effective for reporting periods from FY 2025 onwards. For specified large-cap index constituents and dual-listed companies, sustainability reports are mandatory (due by 30 April 2026 for FY 2025). Guidelines cover governance, strategy, environmental and social topics, and metrics — broadly aligned with TCFD pillars. The SZSE guidance explicitly requires analysis of both financial importance and impact importance (a dual materiality approach), distinguishing it from pure investor-focused regimes.

National sustainability disclosure standards

China’s Ministry of Finance is developing national sustainability disclosure standards designed to converge with ISSB outcomes. The programme is currently in phased development; the first standards are expected to begin with large listed companies and financial institutions, with broader applicability over time. The objective is to build a unified national disclosure system that produces internationally comparable, audit-ready data.

National Carbon ETS

China’s National Carbon Emissions Trading System is the world’s largest by coverage. In 2025, the ETS expanded beyond the power sector to include steel, cement, and aluminium — adding approximately 1,500 enterprises. By 2026, covered entities must submit verified monthly emissions data, directly integrating the financial cost of carbon into corporate planning and governance. Local government officials’ performance assessments are explicitly linked to environmental outcomes, ensuring national targets are enforced through political accountability mechanisms.

Green finance and taxonomy

China has an established green finance infrastructure: the People’s Bank of China (PBOC) Green Bond Endorsed Project Catalogue classifies eligible green projects; the China Banking and Insurance Regulatory Commission (CBIRC) has issued green finance guidelines for financial institutions; and the Asset Management Association of China (AMAC) has published ESG disclosure guidelines for fund managers. The integration of green finance policy with ESG reporting standards is a distinctive feature of the Chinese model.

Vietnam

---

Vietnam is at an earlier stage of ESG formalisation than the other jurisdictions reviewed, but 2025 and 2026 represent a significant acceleration. The country’s approach is anchored in sustainable development policy, state-directed green finance incentives, and a newly established legal framework for green project classification.

Securities market disclosure obligations

Listed companies in Vietnam are required to make sustainability-related disclosures under securities market regulation, including Circular 96 (as amended, most recently by Circular 08/2026 effective February 2026). Mandatory disclosures include specified environmental and social metrics — energy consumption, greenhouse gas emissions, water use, waste management, and workforce data — as well as corporate governance information. The State Securities Commission (SSC) supports issuer capability-building through guidance and capacity programmes. Market practice among leading issuers increasingly references GRI standards as a supplementary framework.

Vietnam’s green taxonomy

In 2025, the Vietnamese government issued Decision No. 21/2025/QD-TTg, establishing Vietnam’s first legally binding Green Taxonomy. The framework provides technical screening criteria for 45 project types across seven sectors — energy, transport, agriculture, water, waste management, buildings, and forestry — to determine eligibility for green financing instruments. This provides the legal foundation for green bonds, green credit, and other sustainable finance instruments aligned with internationally recognised criteria.

Green credit and financial sector incentives

The State Bank of Vietnam (SBV) has developed a legal and supervisory framework for green credit. Green credit grew at an average rate of 21% per year between 2017 and 2025, though it still represents approximately 5% of total outstanding credit. To accelerate the transition, the government has introduced a 2% annual interest rate subsidy for private enterprises and household businesses investing in green and circular economy projects. The SBV has also reduced credit risk weights for loans to SMEs in priority sectors, allowing banks to offer more competitive rates to sustainable businesses.

Cross-jurisdictional comparison: what is common, what diverges

What all jurisdictions share

1. The TCFD disclosure architecture. The governance–strategy–risk management–metrics and targets framework popularised by TCFD has become the universal structural baseline. It appears, in various forms, in the EU’s ESRS, the UK’s company law climate disclosure rules, Switzerland’s climate ordinance, China’s exchange sustainability reporting guidelines, and IFRS S1/S2 (adopted or in development in the UK, China, and others). Even Vietnam’s emerging frameworks draw on international standards that incorporate these pillars.

2. GHG Protocol as the measurement standard. Quantified greenhouse gas emissions — Scopes 1 and 2 routinely, Scope 3 increasingly — are becoming the universal KPI baseline, anchored to GHG Protocol Corporate Standard methodologies. For financial institutions, the PCAF (Partnership for Carbon Accounting Financials) standard is the dominant approach for measuring financed and facilitated emissions.

3. Shift from narrative to audit-ready data. Across all jurisdictions, regulators are moving away from narrative, marketing-driven sustainability disclosures toward quantitative, methodologically defined, and (where applicable) externally assured data. The EU’s direction to prioritise quantitative ESRS datapoints and reduce low-importance items, China’s emphasis on accurate audit-ready data over storytelling, and the UK’s anti-greenwashing rule all reflect this common trajectory.

4. Climate risk treated as financial risk. There is global consensus across central banks, financial supervisors, and securities regulators that physical climate risks (extreme weather, asset stranding) and transition risks (policy changes, technology shifts) must be integrated into enterprise risk management and board-level governance. This is reflected in the supervisory expectations of the ECB, PRA, FINMA, and major central banks globally.

5. ISSB as the emerging global baseline. IFRS S1 and S2 are being adopted, referenced, or aligned with across multiple jurisdictions — including the UK (UK SRS), China (national standards in development), Switzerland (by reference), and many others globally. The ISSB framework is becoming the lowest common denominator for international capital market comparability.

Where jurisdictions fundamentally diverge

The four deepest fault lines

1. Materiality doctrine

The EU and Switzerland require double materiality: organisations must assess and disclose both how ESG matters affect them financially and how they affect society and the environment. All other jurisdictions reviewed focus primarily or exclusively on enterprise-value materiality: disclosures are investor-oriented, focusing on how ESG risks affect the organisation’s financial prospects. This is not merely a definitional difference — it determines which topics must be reported, which data must be collected, and what constitutes a sufficient materiality assessment. Multi-national organisations must currently maintain parallel materiality processes.

2. Taxonomy and classification

The EU Taxonomy is a detailed, legally binding classification system for sustainable activities, generating mandatory KPIs (taxonomy-eligible and aligned turnover, CapEx, and OpEx) for in-scope companies and financial institutions. China has a green finance catalogue serving a similar function within its national green finance system. The UK explicitly declined to adopt a mandatory green taxonomy. Switzerland relies on climate scores and disclosure rather than a classification taxonomy. The US has no federal taxonomy equivalent. Vietnam has a newly established Green Taxonomy, primarily oriented toward credit and investment eligibility rather than disclosure.

3. Enforcement certainty and political direction

The EU and Switzerland embed sustainability disclosure in corporate law with defined consequences for non-compliance. China’s exchange-led approach ties enforcement to listing discipline and the ETS creates direct financial consequences for covered emitters. California’s state legislation imposes mandatory disclosure obligations with defined enforcement mechanisms. In contrast, the US federal position has moved in the opposite direction: the SEC climate rules are stayed and undefended. The UK’s UK SRS are voluntary pending future legislation. Vietnam’s regime is evolving through successive amending circulars, creating some regulatory uncertainty.

4. Value-chain obligations and Scope 3

The EU’s CSDDD and CSRD together impose mandatory value-chain due diligence and, for many companies, mandatory Scope 3 emissions disclosure. California’s SB 253 requires Scope 3 disclosure from covered companies. The UK is moving toward Scope 3 mandates (scheduled for 2028). China is in a phased trialling phase for Scope 3. Vietnam treats Scope 3 as voluntary. The US federal position is to remove Scope 3 requirements. This divergence creates significant operational complexity for supply chains that span multiple jurisdictions.

Sector analysis: financial institutions and enterprises

Financial institutions: guardians, catalysts, and regulated entities

Financial institutions occupy a dual role in the ESG regulatory landscape. They are both directly regulated entities — subject to prudential supervision, product governance requirements, and disclosure obligations — and capital-allocating intermediaries whose lending, investment, and insurance decisions shape the ESG performance of the wider economy. This dual role means ESG strategy for financial institutions is simultaneously a compliance discipline, a risk management capability, and a commercial opportunity.

EU: a multi-layer regulatory stack

EU banks and financial institutions face the most comprehensive ESG obligations globally:

• EBA ESG risk management guidelines: Banks must integrate ESG risk identification, measurement, management, and monitoring into credit, market, operational, and liquidity risk frameworks. The EBA guidelines are binding and subject to supervisory review.
• ECB supervisory expectations: The ECB has set detailed supervisory expectations for climate and environmental risk management under the Single Supervisory Mechanism (SSM). Banks must demonstrate credible planning for transition risk, climate scenario analysis, and data quality.
• Pillar 3 ESG disclosure: EBA binding standards for Pillar 3 ESG disclosures require banks to publish standardised templates covering counterparty carbon footprints, exposures to physical and transition risks, and portfolio alignment metrics — enabling comparability across EU institutions.
• SFDR (product level): Fund managers, asset managers, and financial advisers are required to disclose how sustainability risks are integrated into investment decisions and products at both entity and product level. SFDR reform (ongoing) will change product categories; the existing framework continues to apply in the interim.
• EU Taxonomy (Article 8): Credit institutions and investment firms must disclose taxonomy alignment of their assets — the Green Asset Ratio (GAR) for banks — enabling investors and supervisors to assess portfolio alignment with sustainable activities.

UK: prudential expectations and consumer-facing labelling

UK financial institutions operate under a dual framework: prudential risk expectations from the PRA and consumer-facing sustainability standards from the FCA.

• PRA SS3/19 (updated 2024): Banks and insurers must embed climate risk into governance, risk appetite frameworks, scenario analysis, and capital management. The PRA expects proportionate implementation — larger and more complex institutions face more intensive supervisory engagement.
• FCA climate disclosure rules (PS21/24): Asset managers, life insurers, and regulated pension providers must make TCFD-aligned disclosures at entity and product level. The FCA has conducted reviews of disclosure quality and expects ongoing improvement.
• SDR labelling: Four sustainability labels are available for investment products. The labels require that funds meet specific, evidenced sustainability criteria and disclose their strategy, KPIs, and stewardship approach. The Anti-Greenwashing Rule applies to all sustainability claims, not only labelled products.

Switzerland: climate ordinance and FINMA expectations

• Climate ordinance: Large Swiss banks and insurers are subject to climate disclosure obligations under the Ordinance on Climate Disclosures, including TCFD-aligned reporting with scenario analysis requirements.
• FINMA guidance 01/2023: Sets out supervisory expectations for climate risk governance, risk management integration, and disclosure. FINMA expects institutions to demonstrate how climate risks are reflected in their risk appetite frameworks and business strategies.
• Swiss Climate Scores: A standardised transparency tool for the climate characteristics of financial investments, enabling investors and clients to compare portfolios against climate benchmarks.

United States: market-driven disclosure in a regulatory vacuum

US financial institutions operate without binding federal ESG disclosure or risk management mandates at the bank level (the climate-related guidance from OCC, Federal Reserve, and FDIC has been scaled back). Large US banks and asset managers — particularly those with global operations — continue to disclose climate and ESG data because: international regulatory requirements (EU, UK) apply to their European operations and products; institutional investors (particularly non-US) demand it; and internal risk management practices require it. TCFD-aligned disclosure and ISSB voluntary adoption are common among large US financial institutions.

China: state-guided green finance

Chinese financial institutions operate within a state-directed green finance framework. The PBOC’s green bond catalogue classifies eligible assets; CBIRC guidelines require banks and insurers to integrate environmental and climate risks into credit and underwriting decisions; and the AMAC’s ESG disclosure guidelines apply to fund managers. National sustainability disclosure standards — aligned with ISSB — will formalise reporting requirements for listed financial institutions. Banks are expected to produce sustainability reports aligned with both national policy objectives and exchange listing requirements.

Vietnam: emerging ESG banking

Vietnamese banks are in an earlier stage of ESG integration. The SBV has established a legal framework for green credit, with supervisory expectations for banks to track and report green lending. Leading banks — including Vietcombank and BIDV — are producing structured ESG reports referencing GRI and international frameworks. The SBV’s interest rate subsidy programme creates direct financial incentives for banks to expand green credit portfolios. Access to international capital markets and development finance institutions (IFC, ADB) increasingly requires Vietnamese banks to demonstrate ESG governance.

Enterprises: operational transformation and value-chain accountability

For non-financial enterprises, ESG strategy is operationalised through three interconnected domains: decarbonising operations, managing supply chains, and integrating sustainability into product and capital allocation decisions. The regulatory pull from the EU’s CSDDD and CSRD, Germany’s Supply Chain Act, and California’s SB 253 is reshaping how global supply chains are structured and governed.

Operational decarbonisation

Scope 1 and 2 emissions management is now a baseline expectation for large enterprises in all six jurisdictions reviewed. The methods are well-established: energy efficiency investment, renewable energy procurement (direct power purchase agreements or certificates), fleet electrification, and industrial process changes. The strategic differentiation is increasingly at the Scope 3 level — measuring and reducing supply-chain and product-use emissions — where data quality, supplier engagement, and methodological complexity create significant operational challenges.

Supply-chain due diligence

The EU’s CSDDD (mandatory human rights and environmental due diligence), Germany’s Supply Chain Act (Lieferkettensorgfaltspflichtengesetz), and the UK’s Modern Slavery Act create a layered set of supply-chain accountability obligations for enterprises operating in or supplying into European markets. Companies are required to identify, assess, and where necessary remediate adverse human rights and environmental impacts in their upstream and downstream value chains — in some cases extending to “Tier N” suppliers. This requires investment in supply chain digitisation, supplier engagement programmes, and audit and remediation infrastructure.

Technology sector: AI and digital ESG footprint

A significant and rapidly growing ESG challenge for technology-intensive enterprises is the environmental footprint of digital infrastructure, particularly artificial intelligence systems. The electricity and water consumption of large language model training and inference is becoming a material ESG issue — appearing in corporate sustainability reports, investor questionnaires, and (in some jurisdictions) regulatory disclosure requirements. Companies deploying AI at scale are facing increasing pressure to account for and reduce the environmental footprint of their technology stack.

Capital allocation and transition planning

EU and Swiss regulatory frameworks explicitly require in-scope companies and financial institutions to develop and disclose credible transition plans — showing how capital expenditure, business model, and strategy will evolve to align with climate targets. Transition planning is shifting from a disclosure exercise to a board-level strategic function, with supervisors assessing plan credibility and investor stewardship codes linking executive remuneration to transition milestones.

SMEs: navigating indirect obligations, market demands, and opportunities

Small and medium-sized enterprises (SMEs) are largely exempt from the direct statutory ESG reporting obligations described in this report — the thresholds in most jurisdictions (employees, turnover, public interest criteria) are designed to apply to large companies. However, the idea that ESG is not an SME concern is increasingly untenable. The mechanisms through which ESG reaches SMEs are indirect but powerful, and in some cases more commercially urgent than statutory compliance.

How ESG reaches SMEs

1. The Scope 3 waterfall and value-chain data demands

When a large company must report its Scope 3 emissions under the EU’s CSRD, California’s SB 253, or the UK’s phased obligations, it needs activity data from its suppliers — including SMEs. This creates a “waterfall” effect: ESG requirements cascade from the regulated large company to its unregulated supply chain. SMEs that cannot provide standardised, credible emissions and sustainability data risk losing preferred supplier status or being replaced by suppliers who can. This is not a future risk — it is already reshaping procurement decisions in sectors including automotive, food and beverage, apparel, and electronics.

2. Access to finance and lending conditions

Banks across the EU, UK, and Switzerland are integrating ESG criteria into credit assessment and underwriting — partly in response to regulatory expectations, partly because ESG risks are increasingly treated as credit risks. SMEs that cannot demonstrate baseline ESG governance face higher borrowing costs, reduced credit limits, or exclusion from green and sustainable finance instruments. Conversely, SMEs in priority sectors with demonstrable sustainability performance can access preferential credit terms, green bonds, and sustainability-linked loan structures.

3. Public procurement

Procurement regulations in the EU and several member states increasingly include ESG and sustainability criteria in public tender requirements. SMEs competing for public contracts in regulated sectors must demonstrate minimum sustainability standards, including environmental management systems, workforce policies, and (in some cases) emissions data.

4. Investor and stakeholder screening

SMEs that are investee companies, acquisition targets, or joint-venture partners for larger organisations or private equity funds are increasingly subject to ESG due diligence — a standard component of pre-investment and pre-acquisition assessments.

Jurisdiction-specific SME dynamics

EU: the most explicit SME protection framework

The EU’s Omnibus I is the most explicit example globally of a regulatory design decision to protect SMEs from ESG reporting burden. Key provisions include:

• Raising the CSRD threshold to companies with more than 1,000 employees and more than €450 million net turnover — exempting a large proportion of previously in-scope mid-sized companies.
• Excluding listed SMEs from CSRD mandatory reporting (they can use a voluntary standard).
• Capping value-chain data requests: Companies in scope for CSRD cannot request more information from suppliers with fewer than 1,000 employees than what is required by a forthcoming voluntary SME reporting standard (VSME — the EFRAG Voluntary SME Standard).
• VSME standard: EFRAG published the VSME to give SMEs a proportionate, standardised way to respond to data requests from customers, banks, and investors — reducing the fragmentation cost of answering multiple different questionnaires.

Switzerland: practical tools and market infrastructure

Switzerland has developed practical SME-facing sustainability infrastructure. The federal government’s SME portal (kmu.admin.ch) provides guidance on natural resource management. The “Go for Impact” platform, supported by Swiss Sustainable Finance, helps SMEs conduct materiality assessments and set emissions reduction targets, facilitating access to sustainable finance instruments. The Swiss banking sector’s integration of ESG into lending creates direct financial incentives for Swiss SMEs to demonstrate sustainability performance.

Vietnam: green credit as the primary SME lever

For Vietnamese SMEs, the primary ESG driver is access to green credit. The SBV’s policy framework — reduced credit risk weights, interest rate subsidies for green investment, and a new Green Taxonomy — creates financial incentives that are more immediately relevant to Vietnamese SMEs than disclosure compliance. Vietnamese SMEs exporting to the EU face additional pressure through CBAM (for carbon-intensive sectors) and supply-chain data demands from European buyers.

United States: market and state-level dynamics

US SMEs are primarily affected by market-driven ESG demands (buyers, investors) and, for those doing business in California, by state-level obligations that apply to their large corporate customers. California’s SB 253 will require large companies to report Scope 3 emissions — creating supply-chain data demands that reach through to SME suppliers.

China: listing ecosystem and supply-chain positioning

Chinese SMEs that are part of the supply chains of large listed companies — particularly those subject to mandatory exchange sustainability reporting — face increasing data requests. Unlisted SMEs are primarily affected through market pull rather than direct statutory requirements. For SMEs seeking access to international capital markets or development finance, ESG governance and reporting capacity is an increasingly important prerequisite.

Common SME barriers and how to address them

Institutional examples: ESG strategy in practice

The following examples illustrate how ESG strategy is operationalised across sectors and jurisdictions, and how regulatory context shapes disclosure choices, target-setting, and governance design.

Financial institutions

BNP Paribas (EU — France)

BNP Paribas’ sustainability strategy illustrates how EU banks translate ESG obligations into portfolio policy and client engagement. The bank publishes detailed sectoral financing policies (fossil fuel exclusions, transition support commitments), transition-financing targets, and climate-focused reporting aligned with TCFD pillars and ESRS. Its ESG strategy is operationalised through sector-level limits, client transition engagement programmes, and financed emissions tracking under the PCAF standard.

HSBC (UK)

HSBC’s climate strategy focuses on financed and facilitated emissions targets, disclosed through structured ESG datapacks that reference PCAF methodology, include quality scores for data completeness, and are subject to external limited assurance. The approach demonstrates how a global bank under UK regulatory expectations manages the tension between ambitious transition commitments and data quality limitations — acknowledging gaps transparently while building toward more complete coverage.

UBS (Switzerland)

UBS structures its sustainability approach around strategic pillars — investing for a sustainable future, financing the transition, and reducing its own footprint — and discloses extensively under Swiss corporate law, TCFD, and voluntary best-practice frameworks. Its sustainability report demonstrates how Swiss financial institutions align with evolving standards while maintaining the flexibility of a market-driven (rather than fully prescribed) reporting architecture.

JPMorgan Chase (USA)

JPMorgan Chase’s climate report provides detailed disclosure of financed and facilitated emissions by sector, transition financing targets, and climate risk integration methodology — illustrating how major US financial institutions maintain comprehensive voluntary disclosure in the absence of mandatory federal requirements. The report is framed around investor and stakeholder expectations rather than regulatory compliance, demonstrating the market-driven nature of US financial sector ESG practice.

ICBC (China)

ICBC’s sustainability report reflects the alignment of Chinese bank ESG strategy with national policy priorities: green finance volumes, energy sector transition support, and alignment with national carbon neutrality targets are prominently featured. The report structure follows governance–environment–social pillars consistent with exchange sustainability reporting guidelines, demonstrating how Chinese banks integrate national policy objectives with emerging international disclosure standards.

Vietcombank (Vietnam)

Vietcombank’s ESG report demonstrates an emerging-market financial institution adopting structured ESG reporting that covers sustainable finance initiatives, environmental management, and governance — consistent with SSC guidance and the SBV’s green credit policy framework. The report references international frameworks (GRI) while reflecting the priorities of the Vietnamese regulatory context, including green credit growth targets and climate risk capacity building.

Non-financial enterprises

Siemens (EU — Germany)

Siemens links ESG to product strategy rather than treating it purely as compliance. Its sustainability publications frame ESG around enabling customer emissions reductions (avoided emissions through technology), scaling value-chain transparency, and driving operational decarbonisation — illustrating how industrial companies in the EU combine regulatory compliance (CSRD, CSDDD) with commercial value creation through sustainability.

Unilever (UK)

Unilever’s integrated reporting and governance disclosures show board-level sustainability oversight, sustainability metrics embedded in executive performance management, and detailed value-chain social and environmental data. Unilever’s approach illustrates how a global FMCG company operationalises double materiality in practice — assessing both financial risks from ESG topics and its impacts on people and the environment across a complex, multi-tier supply chain.

Nestlé (Switzerland)

Nestlé’s Non-Financial Statement explicitly references Swiss Code of Obligations obligations and covers environmental performance, social and labour matters, human rights, and anti-corruption. The document demonstrates how Swiss corporate law anchors ESG reporting while voluntary alignment with EU CSRD expectations anticipates value-chain data demands from EU customers and partners.

Microsoft (USA)

Microsoft’s environmental sustainability reporting is organised around four quantified 2030 goals: carbon negative, water positive, zero waste, and protecting ecosystems. The approach is KPI-driven and explicitly includes Scope 3 value-chain emissions — despite no federal mandate requiring it — reflecting investor expectations, California state law applicability, and the company’s global regulatory exposure. Microsoft is also a significant case study for the AI and digital footprint ESG challenge: the company discloses the environmental impact of data centre expansion and AI workload growth.

BYD (China)

BYD’s sustainability reporting through its Hong Kong listing demonstrates how a major Chinese industrial company communicates ESG performance across governance, environmental (including its product’s direct contribution to fleet electrification and emissions reduction), and social dimensions. The report reflects both investor expectations from international capital markets and the Chinese policy context of mandatory sustainability reporting expansion and national carbon neutrality targets.

Vinamilk (Vietnam)

Vinamilk illustrates the hybrid approach common among leading Vietnamese listed companies: mandatory market disclosures required under securities regulation combined with voluntary sustainability reporting aligned with international best practice. The company’s sustainability communications reflect the dual pressures of domestic regulatory compliance and export market ESG requirements — particularly relevant given the EU’s CBAM and supply-chain due diligence frameworks.

Key ESG metrics and reporting frameworks

Core KPI families across jurisdictions

Reporting standards: the global landscape

IFRS S1 and S2 (ISSB)

The International Sustainability Standards Board’s IFRS S1 (general sustainability-related financial disclosures) and S2 (climate-related disclosures) provide the emerging global baseline for investor-focused sustainability reporting. S1 and S2 build directly on TCFD and are being adopted, referenced, or aligned with by over 20 jurisdictions globally. They are the backbone of the UK’s UK SRS, China’s national standards in development, and reference points for Swiss reporting.

ESRS (EU)

The European Sustainability Reporting Standards under the CSRD are the most detailed and prescriptive sustainability reporting standards globally. They cover 12 topical areas across environment (E1–E5), social (S1–S4), and governance (G1), plus cross-cutting standards (ESRS 1 and 2) covering general principles and governance disclosures. Following Omnibus I, a revision process is underway to reduce lesser-priority datapoints and clarify materiality application.

GRI Universal Standards

The Global Reporting Initiative’s Universal Standards are the most widely used voluntary sustainability reporting framework globally, adopted by companies in over 100 countries. GRI supports impact-oriented reporting and is particularly prevalent in markets without a mandatory disclosure framework — including Vietnam, where leading issuers reference GRI as a supplementary standard. GRI standards are also explicitly referenced in ESRS, which allows companies using GRI to partially meet ESRS requirements.

Strategic outlook: uncertainties and implications for organisations

Key uncertainties as of March 2026

EU ESRS revision and SFDR reform

Omnibus I directs a revision of ESRS within six months of entry into force — expected by late 2026 — to remove lesser-priority datapoints, strengthen materiality application guidance, and align with revised CSRD scope. Companies should treat ESRS requirements as a moving target in the near term and build data systems capable of adaptation. SFDR reform will change product classification categories and disclosure requirements for asset managers and financial advisers; the timeline for finalisation is unclear.

US federal trajectory

The SEC climate rules are stayed and undefended; litigation in the Eighth Circuit continues without SEC participation. The federal climate disclosure landscape is unlikely to stabilise in 2026. However, California’s state law requirements, international regulatory obligations for US companies with global operations, and investor demand will maintain ESG disclosure pressure on large US companies regardless of the federal outcome.

UK SRS mandatory effective dates

The UK has published UK Sustainability Reporting Standards for voluntary use, but mandatory application requires future legislation. The timing and scope of any mandate — particularly whether it applies to listed companies, large private companies, or both — remains unsettled. The UK’s approach is to monitor international developments (ISSB adoption, EU outcomes) before legislating.

China implementation depth and Vietnam evolution

China’s exchange sustainability reporting guidelines are mandatory for FY 2025 reports (due April 2026); broader applicability through national sustainability disclosure standards is in phased development. The depth of practical implementation — particularly on Scope 3 and supply-chain data — will take several years to become clear. Vietnam’s regulatory evolution through successive amending circulars creates some uncertainty; primary source accessibility in English remains inconsistent.

Strategic implications for organisations

For multinational corporations

• Build a single ESG data architecture capable of satisfying both double materiality (EU, Switzerland) and enterprise-value materiality (UK, US, China) requirements — the incremental cost of the broader double materiality approach is lower than maintaining parallel systems.
• Prioritise value-chain data infrastructure now: Scope 3 and supply-chain social data are the highest-difficulty, longest-lead-time challenge — and the fastest-growing regulatory requirement across jurisdictions.
• Integrate ESG into transition planning at board level: supervisory expectations in the EU and UK, and investor stewardship codes globally, are elevating transition planning from a disclosure exercise to a strategic governance function.
• Monitor ESRS revision and SFDR reform closely: material changes to EU datapoint requirements in late 2026 will affect both reporting obligations and data systems investment.

For financial institutions

• Financed emissions measurement and portfolio alignment are becoming the central ESG metric for financial institutions globally. PCAF adoption, data quality improvement, and sector-level target-setting are strategic priorities.
• Product governance and anti-greenwashing compliance (SDR in the UK, SFDR in the EU, general securities law in the US) require robust internal controls on sustainability-related marketing and product classification.
• Climate scenario analysis and stress testing are supervisory expectations in the EU, UK, and Switzerland — and increasingly in other jurisdictions. Building institutional capability in this area is a multi-year investment.

For SMEs

• Focus on the data foundations: Scope 1 and 2 emissions calculation, basic workforce and governance metrics, and supply-chain mapping — these are stable regardless of framework changes and directly address customer and lender data requests.
• Use standardised tools: the VSME standard (EU), national SME guidance portals, and industry association toolkits reduce the cost and complexity of ESG reporting significantly compared to bespoke approaches.
• Treat ESG readiness as a commercial asset: SMEs with credible, structured sustainability data can differentiate in procurement, access preferential finance, and position as resilient supply-chain partners — a competitive advantage that compounds over time.

Conclusion

ESG strategy has completed its transformation from a discretionary, narrative exercise to a governance-anchored discipline with legal, financial, and operational consequences. Across the six jurisdictions reviewed in this report, the direction of travel is consistent: quantitative, audit-ready, investor-facing disclosures are replacing vague sustainability narratives; climate risk is treated as a financial risk; and value-chain accountability is extending from large corporations through to their suppliers.

The divergences remain real and material. The EU’s double materiality requirement, mandatory taxonomy KPIs, and value-chain due diligence obligations under CSDDD represent a depth of ESG integration that no other jurisdiction currently matches. The US federal retreat from climate disclosure creates a bifurcated landscape where California state law and investor demand carry obligations that federal regulation has abandoned. China’s state-directed model — integrating national carbon markets, mandatory exchange reporting, and green finance policy — is rapidly formalising into a comprehensive and enforceable regime. Vietnam is building the legal infrastructure for green finance from the ground up, using incentives rather than mandates as the primary lever.

For organisations operating globally, the practical implication is clear: build ESG strategy and data architecture around the most demanding requirements — the EU’s double materiality framework, CSRD/ESRS datapoints, and value-chain due diligence obligations. This investment satisfies all other jurisdictions’ current and foreseeable requirements. It also positions the organisation for the convergence that is under way: the gap between double materiality and enterprise-value materiality is narrowing as investors globally recognise that impact data is risk data.

The organisations best positioned for the decade ahead will be those that treat ESG not as a reporting function but as a strategic intelligence system: a capability for understanding how their business affects and is affected by the world around it, and for turning that understanding into competitive advantage, capital efficiency, and long-term resilience.
