Economists have long argued that a carbon tax is the most efficient route to cleaning up the climate. That takes the “externality” of climate emissions and makes them internal, but also gives companies flexibility to reduce emissions in ways that make the most economic sense.

But a carbon tax is a non-starter in the U.S. Congress has put it off the table. And even companies that favor climate efforts worry a tax would simply create a pile of government revenue to be used for other purposes.

Enter Kerry, who according to reports is “discussing a framework” that would allow companies to buy “high-quality carbon credits” to meet their net zero goals and use the money to accelerate the clean energy transition in developing countries. Many companies already purchase so-called “offsets”—from organizations that plant trees, for instance—to help meet climate goals. But the process is opaque, and it’s not always clear that the money spent is actually accelerating the climate transition. If Kerry’s “framework” can guarantee that money spent on offsets actually goes to projects that promote progress toward net zero, it could be embraced by governments and companies alike.

So watch this space. With Republicans slated to gain seats in Congress in today’s U.S. elections, further climate legislation is dead. But with most Fortune 500 companies having now adopted net zero targets—and with many of them still unclear on how to meet them—a voluntary scheme that produces high-quality “offsets” could gain traction.

PwC breakaway

A bunch of Cypriot PwC partners have broken away from the mothership so they can keep raking in the rubles. The Big Four auditor has refused to service Russian clients since just after the Ukraine invasion in February. But there’s a lot of Russian business in Cyprus, hence the splintering off of what is now a boutique firm called Kiteserve. Around half the new firm’s clients have Russian links, though it claims this will reduce over time. Financial Times

Elizabeth Holmes

Bitcoin seizure

U.S. federal prosecutors have applied for the forfeiture of over $1 billion in Bitcoin that was stolen from the underground site Silk Road in 2012 by a man named James Zhong. When the IRS seized the virtual coins a year ago, they were worth over $3 billion, but the intervening period has not been good to Bitcoin. Silk Road was a drug and money-laundering marketplace that got shut down in 2013, with creator Ross Ulbricht being sent away for life. Reuters
