More than 1,100 municipal landfills emitted at least 3.7 million metric tons of methane in 2021, which had the climate-warming impact of 66 million gasoline-powered vehicles driving for a year or 79 coal-fired power plants, according to a new report by the Environmental Integrity Project, EIP’s report, “Trashing the Climate: Methane from Municipal Landfills.”
To reduce this major but little-discussed source of potent greenhouse gases, EPA must impose regulations that mandate more gas-collection systems at landfills, require more monitoring and accurate reporting of methane emissions, and encourage more composting, recycling, and reduction in the waste stream by consumers.
