Carbon Mapper CEO Riley Duren Named to 2025 TIME100 Climate List
Published on: Oct 30, 2025
We’re proud to share that Carbon Mapper’s CEO and founder, Riley Duren, has been named to the 2025 TIME100 Climate list. Now in its third year, TIME100 Climate recognizes 100 leaders driving measurable and scalable climate action across business, science, and advocacy worldwide.
Carbon Mapper CEO, Riley Duren
Duren’s inclusion celebrates his decades-long leadership in advancing emissions transparency and action through innovative remote sensing technologies.
As CEO of Carbon Mapper, Duren leads a team dedicated to a bold mission: reducing greenhouse gas emissions by making methane and CO2 data accessible and actionable. Under his leadership, Carbon Mapper launched the Tanager-1 satellite, in August 2024, with Planet and other partners.
In just its first year in orbit, Tanager-1 has identified and quantified more than 7,000 methane and CO2 plumes around the world, and is working closely with industry, governments, and civil society partners to translate that data into action. Read more about Tanager-1’s first year in space.
Tanager-1 has been especially effective in revealing emissions from traditionally hard-to-observe sources and regions of the world, equipping governments, businesses, and communities with emissions intelligence to drive swift action. The data is also made publicly available through Carbon Mapper’s data portal, available here. This public data is enabling insights into some of the most pressing and mitigable super-emitters society can address to reduce emissions and improve public health today.
I’m honored to be recognized on the 2025 TIME100 Climate list and to be part of a community dedicated to advancing climate solutions. Methane is one of the most powerful greenhouse gases we can address today, and our mission at Carbon Mapper is to make those emissions visible and actionable, through science, collaboration, and transparency.
A 27-year veteran of NASA’s Jet Propulsion Laboratory, Duren helped launch seven successful satellite missions, from Earth-mapping radars to deep-space telescopes. Recognized with two NASA Exceptional Achievement Medals and the Systems Engineering Excellence Award, Duren has authored more than 70 peer-reviewed publications and serves on the National Academies Committee on Earth Science and Applications from Space (CESAS). His work continues to shape the rapidly evolving ecosystem of global emissions monitoring and mitigation.
