Carbon Mapper® Data Portal

Methane and carbon dioxide super-emitters can be difficult to identify and address because conventional inventories often lack precise, facility-level observations. The Carbon Mapper® Data Portal makes emissions intelligence publicly accessible, helping operators, governments, researchers, and climate organisations identify significant point sources and support direct mitigation.

The portal presents observations generated with precision visible-infrared imaging spectrometers carried by satellites and aircraft. Carbon Mapper processes these observations to pinpoint plumes, quantify emission rates, and track sources over time.

• Plume Detection: Identifies methane and CO₂ point-source plumes using imaging spectroscopy.
• Facility-Scale Localisation: Pinpoints emissions at the granularity needed to associate observations with individual facilities or infrastructure.
• Emissions Quantification: Estimates emission rates so users can understand the scale and significance of detected events.
• Geospatial Visualisation: Publishes global observations through a map-based public web portal.
• Ongoing Monitoring: Supports repeated observations and tracking of super-emitter activity across priority regions.

Its distinctive value is the combination of satellite-enabled facility-scale measurements, transparent public access, and science-backed methods designed to translate emissions data into practical mitigation action.
