Eve Tamme discusses contracted durability in carbon dioxide removal with Luke Pritchard, exploring its implications and challenges in the policy landscape.

In this episode, Eve Tamme digs into contracted durability with Luke Pritchard, Director at Beyond Alliance, a coalition of major carbon dioxide removal buyers. Last month, Beyond Alliance published a white paper with RMI and the American Forest Foundation, developed with input from both engineered and nature based CDR developers, setting out what contracted durability could look like and how it fits into the wider policy landscape.
