Space-Based Climate Technology

Space-based climate technology uses satellites to monitor and measure climate change indicators including greenhouse gas concentrations, methane emissions from oil/gas infrastructure, deforestation rates, sea level rise, and ocean temperature. The sector is growing rapidly as carbon markets and ESG regulations create demand for verifiable emissions data.
