That's right - the financial regulator is now planning on having public companies disclose their greenhouse gas emissions and climate risks, according to the Washington Post and Bloomberg, who cited two people familiar with the matter.

The new rule is expected to be proposed this week and (of course) is being heralded by deep economic thinker Senator Elizabeth Warren. The rules means that "hundreds of businesses would be required to measure and disclose greenhouse gas emissions in a standardized way for the first time," WaPo wrote. 

"The American people and financial investors have a right to know the risks of these investments, and it's taken far too long for the SEC to take action," she told WaPo.

We're not sure if the Washington Post wrote this with a straight face or not, but they commented that the change in rules could "transform the SEC into one of the country's leading enforcers of climate-related disclosures" - a role that everybody knows the SEC was originally intended for, right?
