ESG rule shifts raise disclosure stakes

Sustainability reporting is entering a tougher phase as companies, investors, and regulators reassess how climate and environmental data should be collected, validated, disclosed, and used in decisions.

The latest changes span voluntary standards, disclosure infrastructure, and financial regulation. The Science Based Targets initiative has published Version 2.0 of its Corporate Net-Zero Standard, CDP is splitting into a commercial business and charitable foundation with backing from Permira, and the Financial Conduct Authority is consulting on simpler climate reporting rules for investment products.

Together, the developments point to a more practical and commercially sensitive disclosure environment. Companies are still under pressure to produce climate and environmental information, but the focus is shifting towards usability, implementation, data quality, technology investment, and the cost of reporting.

SBTi’s updated Corporate Net-Zero Standard builds on the first version launched in 2021. The organisation says Version 2.0 reflects advances in climate science, lessons from implementation, and stakeholder feedback. It includes a revised framework for companies setting and managing science-based net zero targets, with more emphasis on transition planning, progress tracking, and practical implementation.

The revised standard arrives after sustained debate over Scope 3 emissions, carbon removals, renewable electricity accounting, and the limits of corporate control over value chain emissions. Companies have often found it easier to set high-level targets than to deliver them across complex supply chains, product portfolios, capital plans, and procurement systems. The new framework responds to that execution gap, while increasing the need to show how targets connect to real operating decisions.

CDP’s restructuring adds another layer. The global environmental disclosure system is becoming two separate organisations: a commercial entity backed by Permira and CDP Foundation, a charitable organisation focused on science-led environmental disclosure. CDP said its 2026 disclosure cycle will continue as planned during the transition.

The restructuring has already sharpened questions over how environmental disclosure systems are funded and governed. The new model could support investment in technology and data services, but it also places greater scrutiny on trust, independence, pricing, and the relationship between disclosure standards and commercial data products. Those questions were central to earlier coverage of how CDP’s restructuring sharpens disclosure questions for companies and investors that rely on its platform.

In the UK, the FCA is taking a more targeted approach to investment product reporting. The regulator has proposed removing detailed product-level reports based on the Task Force on Climate-related Financial Disclosures and replacing them with simpler information for retail investors, while allowing institutional clients to request core greenhouse gas emissions data. The FCA estimates the changes could save investment companies around £20m a year.

The proposal, covered in FCA plans simpler climate reporting, forms part of a broader attempt to reduce complexity while preserving useful information on financially material climate risks. After several years of expanding disclosure obligations, regulators are now having to decide which data genuinely helps investors, customers, and companies make better decisions.

The common problem is that disclosure volume has grown faster than disclosure usefulness. Companies respond to overlapping questionnaires, investor requests, regulatory frameworks, customer demands, ratings agencies, and voluntary standards. The administrative burden has increased, yet many users still complain that information is inconsistent, hard to compare, or disconnected from financial decisions.

Simplification can reduce cost and improve engagement, but it can also remove detail. Commercialisation can fund better tools and data infrastructure, but it can raise questions over access, independence, and incentives. Tougher net zero standards can improve credibility, but they can also expose the gap between public commitments and operational capability.

Finance teams are becoming more central to the next phase. Climate and environmental information now affects capital expenditure, impairment assumptions, insurance, procurement, cost of capital, investor relations, risk registers, and audit processes. As disclosure rules become more focused on decision usefulness, they require closer integration with finance, governance, and operations.

Companies that treat ESG reporting as a periodic compliance exercise will find the system harder to manage. Stronger internal emissions data, supplier information, risk assessment, controls, and governance routines can serve several frameworks at once, reducing duplication while making the information more useful internally.

The latest changes do not remove pressure from ESG reporting. They make the task more exacting. Vague claims will face less tolerance, weak data will be harder to defend, and disclosure will need to connect more clearly with business decisions.
