methane detection from space

Explainer: Satellite-based emissions monitoring and MRV

Introduces satellite-based measurement, reporting, and verification (MRV) for greenhouse gas emissions. Over 30 satellites now measure CO₂ and methane from orbit, with GHGSat detecting individual facility emissions as small as 100 kg/hr of methane. Explains how satellite MRV underpins carbon markets, regulatory enforcement, and corporate Scope 1–3 reporting.
