Carbon Mapper

Founded in 2021 and based in Pasadena, California, Carbon Mapper is an Earth observation company focused on tracking and quantifying point-source greenhouse gas emissions, specifically methane and carbon dioxide. The company utilizes precision visible-infrared imaging spectrometers deployed on satellites and aircraft to detect and measure emissions at a facility scale. Carbon Mapper distinguishes itself through a commitment to open data accessibility, providing observations via a public data portal to maximize impact and transparency.

Currently, the company’s data portal showcases observations of over 27,000 methane plumes and 5,000 CO2 plumes globally, representing a substantial volume of emissions data. Carbon Mapper operates as a unique public-private partnership, supported by philanthropic funding, and is actively deploying a constellation of satellites to enable sustained, high-frequency monitoring of key regions.

Recent activity highlights Carbon Mapper’s growing influence in the climate technology space, with presentations at events like the 2025 AGU meeting and COP30, as well as recognition of its CEO on the 2025 TIME100 Climate list. The company’s data is intended to support mitigation efforts by providing actionable insights to governments, industry, and non-profit organizations, facilitating science-based decision-making and emissions reduction strategies.
