The Securities and Exchange Commission (SEC) approved a new rule on March 6 requiring public companies to disclose emissions and other climate-related details. This regulation, aimed at increasing transparency for investors on climate risks, is expected to boost the sustainable accounting industry, potentially increasing spending by filers on assurance firms by up to $907 million a year, an 18% increase over current levels. However, the rule has faced significant opposition, leading to a flurry of lawsuits from states, companies, and nonprofits, with West Virginia Attorney General Patrick Morrisey accusing the SEC of exceeding its authority. The Fifth Circuit Court has temporarily blocked the rule, prompting reactions from various sectors. House Republicans celebrated the court's decision, while the rule's suspension has sparked debates about the SEC's approach to climate disclosure and its implications for the fossil fuel industry.
