As 2025 draws to a close, the global climate and sustainability landscape remains in flux. This edition highlights how regulatory developments are increasingly defined by two parallel trends: streamlining and retreat in established markets, and deeper international alignment in emerging ones.

In Europe, the EU’s Omnibus initiative is simplifying overlapping ESG frameworks, including the CSRD, CSDDD, and EU Taxonomy. Its aim is to reduce administrative burdens and improve compliance efficiency. Meanwhile, the United States is seeing a mix of federal deregulation and proactive state-level action, with extended compliance timelines and new climate disclosure laws taking shape. Beyond these regions, Asia-Pacific jurisdictions such as China and Singapore have introduced mandatory climate disclosure rules aligned with global standards, while Mexico and South Africa are embedding international frameworks into domestic law.

This edition highlights:

  • South Africa’s move to a compulsory carbon-control regime, marking a turning point in its climate policy.
  • The U.S. Clean Air Act Subpart OOOOb and changes to GHG reporting and chemical regulations.
  • The EU’s expanded product sustainability rules, forced labor regulations, and the Critical Raw Materials Act.
  • Updates to key regulations covered in previous editions, including California’s SB 253 and SB 261, revised climate reporting timelines in Singapore, proposed changes to the EU Omnibus, and expanded state-level activity on EPR and building performance standards in the United States.

ERM’s Global Regulations Radar offers a high-level overview of the most significant ESG and EHS regulations impacting companies with global operations. As regulatory landscapes evolve, organizations must stay agile—adapting to new requirements, managing compliance risks, and seizing opportunities for sustainable innovation.
