SAGE (Spatial Asset Greenhouse Gas Emissions)

SAGE (Spatial Asset Greenhouse Gas Emissions) fuses data from a six-mission satellite constellation — ESA Sentinel-5P TROPOMI, NASA OCO-2 and OCO-3, and JAXA GOSAT-I, GOSAT-II and GOSAT-GW — to produce directly measured Scope 1 emissions and satellite-derived Scope 2 estimates at individual asset resolution. Co-located CO₂, CH₄, NO₂, CO and SO₂ retrievals fingerprint combustion versus fugitive emission sources, with quantified uncertainty typically in the 5–20% range. Results roll up to company and portfolio level, support monthly and annual GHG disclosures, and are certified to ISO 14064-1 and the GHG Protocol. Historical baselines extend 10+ years.
