Climate change is an enormous risk to the economy and markets. If the world manages to solve its collective action problem, investors will cheer — but, as with any major change, there will be winners and losers.

What to watch: Moody's, the ratings agency, is putting together what it calls a "framework to assess carbon risks." Individual companies will be given a carbon transition assessment, or CTA, which measures how well they'll be able to operate in a low-carbon economy.

"Issuers assigned the highest scores, CT-1 and CT-2, exhibit advanced positioning for carbon transition. These companies typically have a business model that benefits from the transition to a low-carbon economy. By contrast, companies assigned the lowest scores, CT-9 and CT-10, exhibit poor positioning and typically have business models that are fundamentally threatened by carbon transition over any time horizon, including the long term."
— Moody's Investors Service

Why it matters: Carbon transition risk is already built into Moody's existing credit ratings, but it's not a large part of those ratings, largely because it's far from clear that a major carbon transition is actually going to happen. Now that Moody's is separating out this risk into a discrete CTA score, investors will be able to get a much clearer idea of which companies are successfully positioning themselves for a green future.

Trump refuses to commit to peaceful transfer of power if he loses

President Trump repeatedly refused to say on Wednesday whether he would commit to a peaceful transition of power if he loses the election to Joe Biden, saying at a press briefing: "We're going to have to see what happens."

The big picture: Trump has baselessly claimed on a number of occasions that the only way he will lose the election is if it's "rigged," claiming — without evidence — that mail-in ballots will result in widespread fraud. Earlier on Wednesday, the president said he wants to quickly confirm a replacement for Justice Ruth Bader Ginsburg because he believes the Supreme Court may have to decide the result of the election.

"Not enough": Protesters react to no murder charges in Breonna Taylor case

A grand jury has indicted Brett Hankison, one of the Louisville police officers who entered Breonna Taylor's home in March, on three counts of wanton endangerment for firing shots blindly into neighboring apartments.

The state of play: Angering protesters, the grand jury did not indict any of the three officers involved in the botched drug raid on homicide or manslaughter charges related to the death of Taylor.
