Can we really count on land to deliver climate mitigation?

Our new highlight unpacks what AR/BECCS can do — and where uncertainties bite (carbon stocks, permanence, local climate effects).

By this time yesterday, we were seeing everyone again for the Climate Research Communication Network 6th Meeting!

We kept doing what this network does best:connect project/comm managers & DEC people from EU climate projects so we don’t all reinvent the wheel &so we can amplify each other’s work💪🌍
