Montreal-based GHGSat has ordered two additional satellites from SFL Missions for its greenhouse gas monitoring constellation. The two companies have been longtime partners, with SFL Missions building 11 satellites for GHGSat over the past decade. 

These satellites will be GHGSat-C18 and -C19. They will be built on SFL’s high-performance 15 kg NEMO satellite platform. GHGSat ordered two satellites from SFL last year as well. 

GHGSat monitors greenhouse gas emissions from space with proprietary sensor technology, monitoring industries like oil and gas, coal mining, and waste management. It works with companies and governments including ExxonMobil, Aramco, and the UK Space Agency to address methane emissions.

“SFL has been a trusted partner throughout our journey, and their expertise has played a critical role in helping us push the boundaries of what’s possible in environmental monitoring,” said Stéphane Germain, CEO of GHGSat. “By leveraging their expertise in building microsatellite technology, we have been able to transform the emissions-monitoring industry with innovative, low-cost solutions that deliver actionable emissions data from space.”
