Internal briefing for Inside Practice. Coverage focuses on ESG developments shaping legal practice, law-firm operations and corporate legal department work.
Disclosure & Reporting
SEC moves from climate-disclosure mandate to rescission
The SEC proposed rescinding its 2024 climate-related disclosure rules in their entirety, with a 60-day comment period after Federal Register publication. For securities, governance and public-company teams, the immediate point is not that climate disclosure disappears, but that U.S. federal mandatory disclosure strategy is again turning on materiality, anti-fraud risk and issuer-specific controls.

Accountancy Europe backs revised ESRS stability after the 3 June consultation deadline
Accountancy Europe said the European Commission’s revised ESRS strike a workable balance between simplification and Green Deal objectives, while warning that only practice will prove whether the burden reduction is real. Law firms advising CSRD reporters should treat the post-consultation phase as a governance and implementation window rather than a reason to pause double-materiality, perimeter and assurance planning.

EFRAG restarts the non-EU group standard for companies with significant EU activity
EFRAG is resuming work on a non-EU ESRS group sustainability reporting standard for groups with significant EU activity under CSRD Article 40a, with a July exposure draft, 100-day consultation and field testing. Cross-border legal teams should expect multinational clients to ask whether EU-facing reporting can be reconciled with ISSB, local listing rules and group-level controls.

UK SRS moves toward FCA rulemaking for listed-company reporting
Latham’s June UK PLC update notes that the UK-endorsed ISSB standards, now UK SRS, are moving toward FCA rules for listed companies, with a policy statement expected in autumn 2026. For legal and governance teams, the UK track is becoming a practical board-calendar issue: disclosure controls, finance ownership and Companies Act reporting strategy need to be aligned before formal obligations land.

ASIC turns first mandatory sustainability reports into a disclosure-quality checklist
ASIC reviewed early Australian sustainability reports and flagged practical lessons on disclaimers, cross-referencing, measurement uncertainty, climate targets and material information. The legal takeaway is sharply operational: ESG reporting is now being tested as statutory disclosure, not voluntary narrative.

Brazil’s CVM makes ISSB-aligned sustainability reporting voluntary
Brazil’s CVM revoked the mandatory path for ISSB-based sustainability financial reporting for public companies, making the regime voluntary for fiscal years beginning January 1, 2026. The shift creates a strategic disclosure choice for issuers and counsel: whether to keep reporting for investor positioning, and how to manage opt-out notices, assurance and the three-year continuity rule for companies that opt in.

Climate & Greenwashing Litigation
ESG statements are moving deeper into UK securities-claims risk
Slaughter and May warns that ESG statements, even aspirational and forward-looking ones, are increasingly relied on by claimants and scrutinised with hindsight. For issuers and advisers, this turns sustainability copy, supply-chain assurances and governance claims into verification workstreams that need the same discipline as financial disclosure.

Boohoo ESG accountability decision sharpens the securities-claims playbook
Travers Smith’s ESG library highlights the Boohoo s.90A FSMA case management decision as a sign that reliance, causation and case sequencing will shape future ESG accountability claims. Litigation teams should watch how securities claims around sustainability and supply-chain statements are structured before they become post-event crisis work.

Climate governance is being reframed as a board-level legal and fiduciary question
Legal Charter 1.5 and Chapter Zero are convening non-executive directors, general counsel, senior executives and legal professionals during London Climate Action Week to discuss climate and nature through legal and fiduciary lenses. For firms, this is a market signal that climate advice is moving from specialist ESG teams into mainstream board governance and director-duty counselling.

Supply Chain & Human Rights
Canada’s S-211 reporting cycle makes forced-labour due diligence publicly auditable
Canada’s S-211 regime requires covered government institutions to report by May 31 on steps taken to prevent forced and child labour in supply chains, with reports made public and held in a Public Safety Canada registry. In-house legal and procurement teams should assume the next wave of scrutiny will focus on supplier checks, board sign-off, registry consistency and remediation evidence.
EUDR simplification cuts burden but keeps the 30 December 2026 implementation date in view
Baker McKenzie’s update on the Commission’s EUDR simplification review notes expected compliance-cost reductions of about 75%, while making clear that the regulation is not being reopened and large and medium companies still face the 30 December 2026 application date. Supply-chain counsel should treat simplification as a scoping and systems issue, not a deferral.

CSDDD Omnibus changes push due diligence toward risk-based scoping
Recent Omnibus coverage describes a narrowed CSDDD approach, higher thresholds, delayed compliance and a more risk-based scoping exercise using reasonably available information. For legal teams, the likely work shifts from universal supplier questionnaires to defensible scoping, escalation, evidence trails and governance of severe-risk findings.

ESG Backlash & DEI
Four state attorneys general sue ISS over alleged ESG-disclosure failures
Texas, Nebraska, Iowa and West Virginia sued ISS, alleging the proxy adviser failed to disclose that ESG considerations shaped voting recommendations. The case set keeps ESG backlash squarely in the proxy-advice and stewardship ecosystem, forcing corporate counsel to monitor both shareholder-voting mechanics and state consumer-protection theories.

Corporate racial disclosure may become a rare left-right governance convergence point
The Columbia Blue Sky Blog argues that corporate racial disclosure may attract support from both sides of the political spectrum even as DEI remains contested. For legal and governance teams, that suggests DEI-risk counselling may be moving away from slogan-level positions toward disclosure design, board oversight and defensible data architecture.

Firm Sustainability & Net Zero
Legal Business ESG Summit puts litigation, green claims and AI on the legal-leadership agenda
Legal Business, powered by Legal 500, is positioning its July ESG Summit around regulatory divergence, ESG litigation risk, governance, green claims, transition finance, responsible investment and AI’s impact on ESG compliance. For law firms, the agenda shows ESG becoming a client-facing advisory, disputes, governance and technology topic rather than a standalone sustainability vertical.
