California Gov. Gavin Newsom signs law requiring big businesses to disclose emissions

California will soon require big businesses to report a wide range of greenhouse gas emissions. California Gov. Gavin Newsom signed the nation’s most sweeping emissions disclosure law for companies making more than $1 billion annually. The law will apply to more than 5,000 businesses. Advocates say it will lead to more transparency about how businesses contribute to climate change. They also hope it will nudge companies to examine how they can lower their emissions. But opponents of the bill say the rules will be burdensome and lead to inconsistent reports. State regulators will have to sign off on how the rules will be implemented.
