I'm still a bit fuzzy on how this'll actually work, but I'm glad the SEC's forcing companies to take climate change seriously as a business risk.

SEC to Require Climate-Change Risk Disclosures Under New Plan

Companies will need to reveal detailed information about their greenhouse gas pollution under a new U.S. Securities and Exchange Commission plan, portending a major shift in how corporations must show they are dealing with climate change. 

For the first time ever, the agency plans to require businesses to outline the risks a warming planet poses to their operations when they file registration statements, annual reports or other documents. Some large companies will have to provide information on emissions they don’t make themselves, but come from other firms in their supply chain.
