The EU and China both endorse the Open Coalition - that's huge.
Carbon pricing is one of our best assets for the climate.
Over 80 countries now have a carbon price.
Today we launch the Open Coalition on Compliance Carbon Market.
Together with Brazil and other partners, let’s do it right, and let’s do it together.

Really fun listen. My only minor complaint is that they describe the amassing of the shadow fleet as an "unintended consequence," suggesting that policymakers didn't expect it. I know for a fact that's not the case!
Maybe economists should replace "unintended" with "unavoidable" (Greek shippers?)

When Russia invaded Ukraine, western countries sanctioned Russian oil. But Russian oil exporters quickly sailed around them, building a shadow fleet of rickety oil tankers to move that sanctioned oil around the world.
