ExxonMobil has sued California over a pair of state laws that force big companies to disclose financial climate risks to shareholders and the full greenhouse gas emissions resulting from their businesses — arguing that the measures violate the company’s free speech. It’s the latest example of Exxon, the biggest U.S. oil company, wielding the First Amendment as both a shield and sword in court.
The California Climate Accountability Package, which passed in 2023, would make companies doing business in California disclose emissions that result from the use of their products — also known as “Scope 3” emissions. That category makes up the vast majority of emissions from the oil and gas industry, but companies including Exxon have fought to avoid making them transparent.
