Our mission

Our mission is to drive greenhouse gas emission reductions by making methane and carbon dioxide data accessible and actionable.

Data and Science

Our data portal includes observations of methane and CO2 super-emitters across the globe. We detect, pinpoint and quantify emissions at a facility-scale and make this data available to the public, providing accessibility and transparency to maximize impact.

Open data portal

A unique public-private partnership

To accomplish our mission, Carbon Mapper leads a unique coalition of partners — powered by philanthropy — to develop and deploy two satellites with capabilities to detect and quantify methane and CO2 super-emitters at a level of granularity needed to support direct mitigation action.

Translating data to impact

Our data helps fill gaps in understanding the size and scope of methane and CO2 emissions and supports direct mitigation from facilities and operators. We partner with groups across government, policy, industry, and nonprofit groups to help translate data into meaningful insights and tools that help decision-makers around the globe.
