Put a Lid on Landfill Methane

    Newer Older

    Landfills are rich in methane-producing bacteria that decompose garbage. Typically, excess methane simply leaks into the atmosphere, but a system of pipes can capture the gas underground and divert it to power plants instead. Installing such systems on a broad scale could reduce human-caused methane emissions by 8 percent, according to modeling conducted by Shindell's team. Visible here are pipes that are part of a methane capture system at a landfill in the state of Washington.

    This slideshow highlights key emission control strategies that could help limit the release of black carbon and methane into the atmosphere. NASA's Drew Shindell and a team of colleagues from around the world have published a study in Science that highlights how various regions and countries would benefit by limiting emissions of the two pollutants.
