Sucking up CO2

Data and science for climate action

Big Picture 

Addressing the climate crisis requires action on several fronts, including critical reductions in emissions and large-scale deployment of carbon removal. Solutions need to respect science and support just outcomes, and there’s no time left for approaches that don’t work.

How it Works

CarbonPlan builds open tools and resources for the evaluation and deployment of robust climate programs. They share learnings through public communication and collaboration with journalists. And they help organizations in the public and private sector make better decisions to advance their climate goals.

Unfair Advantage

CarbonPlan’s team brings together cross-cutting expertise in open science, climate change science, and climate policy. Their focus on transparency and quality is setting a high bar on the design of climate programs. They’ve also structured their organization to avoid conflicts of interest and be able to call out objectively what’s working — and what’s not.
