🗞️ Driving the news: The California Air Resources Board (CARB) has postponed the formal rulemaking process for its landmark climate disclosure laws—SB 253 and SB 261—until Q1 2026
• The delay follows significant public feedback and ongoing discussions regarding the scope of companies covered
• However, the reporting start dates remain unchanged, with enforcement discretion expected during the initial cycles

🔭 The context: California’s SB 253 and SB 261, signed into law in 2024, are among the most ambitious climate disclosure mandates in the U.S., applying to thousands of companies doing business in the state
• SB 253 requires Scope 1, 2, and 3 emissions reporting from firms with revenues over $1 billion, while SB 261 mandates climate risk disclosures for companies with revenues above $500 million
• These laws are proceeding even as the U.S. SEC’s national climate disclosure rules face uncertainty and delays

🌍 Why it matters for the planet: Robust emissions and climate risk disclosures are critical for enabling transparent, data-driven action on climate change
• California’s regulations cover Scope 3 emissions—often the largest share of a company’s footprint—and push U.S. firms toward value chain accountability
• As federal efforts stall, the state’s leadership sets a precedent for climate governance and can accelerate private-sector decarbonization by requiring greater visibility into emissions hotspots and financial exposure to climate risks

⏭️ What's next: CARB is expected to release its rulemaking proposal in early 2026, alongside continued consultations with stakeholders
• A draft reporting template for Scope 1 and 2 emissions has been issued to guide voluntary compliance in the 2026 cycle, with feedback due by October 27
• Companies are advised to begin preparing internal systems and value chain data collection ahead of mandatory Scope 3 disclosures beginning in 2027

💬 One quote: “If these rules are implemented as planned, California will have the most comprehensive emissions disclosure framework in the U.S., potentially reshaping corporate climate accountability nationwide.” – Environmental policy analyst (unnamed, contextual synthesis)

📈 One stat: Over 4,000 U.S. companies are expected to fall under the scope of California’s new climate disclosure laws, according to CARB’s preliminary list
