When organic waste ends up in landfills, it produces methane — a powerful climate pollutant —as it decomposes.
In the U.S., landfills are our third largest source of methane and a major driver of climate change. They also emit large amounts of health-harming and even cancer-causing pollution, such as toxic benzene, that endangers nearby communities. And to make matters even worse, they cause noise and odor problems.
Recent scientific studies indicate that landfills may be an even greater source of pollution than we thought. A study led by scientists at Carbon Mapper and recently published in the journal Science surveyed 20% of open U.S. landfills and found significant point source emissions at the majority (52%) of sites.
Earlier work based on data from the TROPOMI space satellite looked at 73 landfills and found their pollution…
