🗞️ Driving the news: California’s Air Resources Board (CARB) has released draft guidance for corporate climate risk disclosures under SB 261, a new law requiring large companies — those with at least $500 million in global revenue — to report climate-related financial risks starting January 1, 2026
• The five-point checklist clarifies expectations for companies and aims to address industry concerns about implementation amid incomplete final regulations

🔭 The context: SB 261 is part of a broader legislative push in California to improve corporate climate transparency
• Alongside SB 253, which mandates full value chain emissions reporting for firms with over $1 billion in revenue, these laws position California at the forefront of U.S. climate disclosure policy
• Together, they mirror elements of the EU’s Corporate Sustainability Reporting Directive (CSRD) and anticipate federal rules from the U.S. SEC that have faced legal delays

🌍 Why it matters for the planet: Mandatory climate risk disclosures increase accountability, enabling investors, regulators, and civil society to evaluate corporate exposure to climate threats and transition risks
• By embedding climate analysis into financial decision-making, SB 261 could help steer capital away from high-risk, high-emissions assets and drive more resilient business strategies in the face of worsening climate impacts

⏭️ What's next: CARB will finalize the rules for SB 261 later this year, ahead of the law’s enforcement date. Businesses are expected to begin submitting disclosures in 2026, with compliance reports due annually
• As SB 253 also comes into effect in stages, corporations must prepare for increased scrutiny of both climate risks and emissions, likely prompting more robust sustainability governance and data tracking systems

💬 One quote: “This guidance is a signal to companies that climate risk is now a core part of doing business in California — not just a sustainability add-on.” — Environmental law expert (paraphrased, as direct quotes were not provided in the article)

📈 One stat: SB 261 applies to all companies with $500 million or more in global annual revenue doing business in California — a threshold that could capture thousands of firms across sectors
