The SEC did a sensible thing on climate change. A right-wing campaign is trying to kill it.

As drought spreads and sea levels rise, the economic impacts of climate change will run in the trillions of dollars. The insurance firm Swiss Re projects climate disasters would cost the world as much as $23 trillion by 2050, bigger than the impact from the pandemic and the Great Recession of 2009 combined.

It’s reasonable business planning to account for all this foreseeable risk — just like planning for cyberattacks or business disruptions from a pandemic. Last year, for instance, the US had to spend $145 billion dealing with floods, fires, and other climate-related disasters.

Yet somehow, climate change has fallen through the cracks of US financial regulation. Publicly traded companies are required to disclose information about “material” risks that affect their company regardless of their cause, from sanctions to supply chain chaos. But there are no uniform standards for disclosing how much fossil fuel pollution they generate or the impact that climate change could have on their future growth. Instead, companies have been left free to inflate their environmental progress, all with little scrutiny from the public.

This kind of information is, in theory, essential to a functioning free market, so investors can make decisions based on complete information. But fossil fuel interests, conservative ideologues, and corporate trade groups are striving to keep shareholders in the dark on climate risks.
