👉 ACCA urges phased UK sustainability reporting rollout

The Association of Chartered Certified Accountants has called on the Financial Conduct Authority to phase in new UK Sustainability Reporting Standards (SRS 1 and SRS 2) as the regime expands beyond the former TCFD framework. The proposals increase disclosure scope and data requirements for listed companies, necessitating upgrades in reporting systems, governance and data infrastructure. For investors and financial institutions, delayed or phased implementation may affect comparability and timing of decision-useful data, with implications for portfolio alignment, risk modelling and capital allocation.

👉 Commission opens EU Taxonomy criteria review

The European Commission opened feedback on revisions to the EU Taxonomy’s technical screening criteria on 17 March, with comments due by 14 April and adoption planned by summer 2026. The draft changes would simplify criteria, clarify compliance tests and align requirements with updated EU legislation and technology developments across sectors including energy, transport, manufacturing and construction. For investors and banks, easier taxonomy application could improve usability of alignment metrics in capital allocation, product design and green asset ratio reporting, while reducing processing burden.

👉 GRI launches consultation on expanded pollution disclosure standards

The Global Reporting Initiative has opened consultation on revised pollution reporting standards, including new requirements on soil contamination, enhanced air emissions disclosures (GRI 305), and expanded incident reporting under GRI 306. The proposals aim to address gaps in data completeness and comparability, with consultation open until 8 June. For investors and financial institutions, broader and more granular disclosures may improve risk assessment and portfolio alignment but increase reporting burdens and data processing complexity, particularly where interoperability with EU standards is required.

👉 EU green bond reviewer supervision starts in June

The Commission confirmed that, after 21 June 2026, firms providing external reviews for European green bonds must register with ESMA under the final technical rules for the EuGB framework. The requirement affects external reviewers and issuers using the voluntary label, whose proceeds must be allocated to EU Taxonomy-aligned activities. For investors, centralised supervision should strengthen assurance quality around pre- and post-issuance disclosures, with implications for bond selection, mandate eligibility and greenwashing controls.

👉 California advances Scope 3 disclosure rules for large firms

The California Air Resources Board has outlined implementation pathways for Scope 3 emissions reporting under SB 253, applying to companies with over $1bn revenue operating in California. Scope 1 and 2 disclosures begin in 2026, with Scope 3 required from 2027. Proposed methodologies include spend-based, activity-based and supplier-specific approaches. For investors and financial institutions, increased Scope 3 coverage may improve portfolio-level emissions visibility but introduces data uncertainty, model risk and higher compliance costs across global supply chains.

👉 Switzerland proposes CSRD-aligned sustainability reporting law

The Swiss Federal Council has proposed a Federal Act on Sustainable Corporate Governance aligning reporting and due diligence requirements with EU CSRD and CSDDD frameworks. Reporting obligations would apply to companies with ≥1,000 employees and CHF450m revenue, requiring ESRS-compliant disclosures, while due diligence rules would target firms with ≥5,000 employees and CHF1.5bn revenue. For investors and financial institutions, alignment may improve cross-border data comparability but narrows the reporting perimeter, potentially reducing coverage while increasing compliance and supply chain risk oversight requirements.

👉 UNEP FI has released an ESRS disclosure module that maps banks’ existing PRB impact analysis into ESRS materiality language, creating a structured workflow for portfolio-level impact assessment. For banks, the tool could lower CSRD implementation and assurance costs by reusing existing analysis, improving comparability and audit trails rather than requiring a separate assessment process.

👉 European ESG bond markets entered 2026 with weaker primary supply but resilient demand. ESMA said ESG bonds outstanding from EU issuers reached €2.7tn in 2025, up 8% year on year, while green bond issuance fell 18% to €279bn. EuGB issuance still reached almost €20bn across 20 issuers, indicating that tighter taxonomy-linked structures are gaining market share despite slower overall supply.

👉 The EU green bond segment continued to build scale in March as the Commission prepared full supervision of external reviewers from 21 June 2026. The Commission said more than 30 EuGBs worth about €30bn had been issued so far, around 7% of European green bond issuance in 2025, with deals oversubscribed and supported by a broad investor base.

👉 Divergence between corporate ESG performance and third-party ratings persists due to data architecture mismatches, with agencies such as MSCI, Sustainalytics, S&P Global and LSEG prioritizing standardized, granular disclosures over narrative reporting. For issuers, this creates a transmission gap affecting ratings-linked capital costs and index inclusion. Disclosure optimisation, aligning reported metrics with agency methodologies, emerges as a lower-cost lever versus strategy changes, with implications for investor perception, benchmark positioning and access to passive ESG flows.

👉 UNEP FI has issued ESRS implementation guidance tailored to banks, clarifying application of 2023 standards and proposed 2025 amendments across impact materiality, portfolio-level metrics, and target-setting. The framework integrates existing UNEP FI tools into ESRS workflows, enabling reuse of internal risk and impact data. For banks, this may reduce compliance duplication and improve consistency of disclosures, with implications for comparability, supervisory scrutiny and alignment with CSRD reporting requirements.

👉 UNEP FI has launched the Climate Pathways Navigator, a scenario data platform developed with International Institute for Applied Systems Analysis and Potsdam Institute for Climate Impact Research, providing financial institutions with standardised, sector-level decarbonisation pathways. For banks, insurers and asset managers, access to consistent scenario data supports portfolio alignment modelling, target-setting and client engagement, with implications for transition risk pricing, capital allocation and cross-sector comparability of climate strategies.
