My latest just out today in @sciencemagazine: "The costs of “costless” climate mitigation," joint with Matt Kotchen & James Rising.

IPCC, McKinsey, energy-systems models & climate-economic ones have quite a bit of disagreement around what it costs to cut emissions.

The biggest disagreement: how much of it is free, and what does "free" mean.

Or more to the point, what does it take to get the free stuff actually done. (Hint: It takes policy.)
