Satellite data finds landfills are methane ‘super emitters’

Associated Press  

BENGALURU, India — Landfills are releasing large amounts of planet-warming methane gas into the atmosphere from the decomposition of waste and are a significant contributor to such emissions in urban areas, a study suggests. “This is the first time that high-resolution satellite images have been used to observe landfills and calculate their methane emissions,” said Joannes Maasakkers, lead author of the study and atmospheric scientist at the Netherlands Institute for Space Research. “This new work shows just how important it is to manage landfills better, especially in countries like India where landfills are often on fire, emitting a wide range of damaging pollutants,” said Euan Nisbet, an Earth scientist at Royal Holloway, University of London, who wasn’t part of the study. At last year’s United Nations climate conference, 104 countries signed a pledge to reduce methane emissions by 30% by 2030 compared with 2020 levels.
