Exxon Mobil sued California late Friday, arguing two 2023 climate laws violate its free-speech rights by compelling emissions and risk disclosures. The rules would require companies to report product-use emissions starting in 2026 under the Greenhouse Gas Protocol and publish climate-related business risks. Exxon calls the measures overreach that misattribute responsibility and create double counting; state officials defend them as transparency. The case echoes a Chamber of Commerce challenge now on appeal, as agencies press ahead and allies and opponents file briefs in a widening disclosure fight.
