A nonprofit group, Carbon Mapper, will use data from NASA’s EMIT mission, plus current airborne and future satellite instruments, to survey waste sites for methane emissions. Observations from the Earth Surface Mineral Dust Source Investigation (EMIT) and other NASA science instruments will be pa
Methane is a potent greenhouse gas, the source of roughly a quarter to a third of global warming caused by humans. The aim of the new initiative is to establish a baseline assessment of global waste sites that emit methane at high rates. This information can support decision-makers as they work to reduce the concentration of the gas in the atmosphere and limit climate change.
“Currently, there is limited actionable information about methane emissions from the global waste sector. A comprehensive understanding of high-emission point sources from waste sites is a critical step to mitigating them,” said Carbon Mapper CEO Riley Duren. “New technological capabilities that are making these emissions visible – and therefore actionable – have the potential to change the game, elevating our collective understanding of near-term opportunities in this often overlooked sector.
“NASA JPL has a decadelong track record of using airborne imaging spectrometers to make high-quality observations of methane point-source emissions,” said Robert Green, EMIT’s principal investigator at JPL. “With EMIT we have employed the same technology in a spaceborne instrument, enabling us to collect information on localized methane sources from orbit.”
