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.

Oil prices in Asian trading are up a bit on these reports, but maybe the market is flush enough to absorb some shut in of Russian oil?

This is described as an "exemption" but since the UK and EU plan to align carbon markets so that UK and EU firms will pay the same price that's not quite right. It's instead aligned w the EU intent to credit domestic prices already paid. More a mini coalition!

Two points counter the top-line narrative in this piece:

2. The coming "climate competitiveness strategy” could be a #CBAM?!?
