The U.S. government has released a strategy to reduce methane emissions, which comprise nearly nine percent of all the greenhouse gas emitted as a result of human activity in the U.S.
The new strategy builds on progress to date and takes steps to further cut methane emissions from landfills, coal mining, agriculture and oil and gas systems through cost-effective voluntary actions and basic standards.
Methane pollution is projected to increase to a level equivalent to over 620 million tonnes of carbon dioxide pollution in 2030 without additional action to reduce emissions.
Landfills: In the summer of 2014, the U.S. Environmental Protection Agency (EPA) will propose updated standards to reduce methane from new landfills and take public comment on whether to update standards for existing landfills.
Coal Mines: In April 2014, the Department of the Interior’s Bureau of Land Management (BLM) will release an Advanced Notice of Proposed Rulemaking (ANPRM) to gather public input on the development of a program for the capture and sale, or disposal of waste mine methane on lands leased by the federal government.
Agriculture: In June, in partnership with the dairy industry, the USDA, EPA and DOE will jointly release a “Biogas Roadmap” outlining voluntary strategies to accelerate adoption of methane digesters and other cost-effective technologies to reduce U.S. dairy sector greenhouse gas emissions by 25 per cent by 2020.
Oil and Gas: Building on success in reducing methane emissions from the oil and gas sector through voluntary programs and targeted regulations, the Administration will take new actions to encourage additional cost-effective reductions. Key steps include:
In the spring of 2014, EPA will assess several potentially significant sources of methane and other emissions from the oil and gas sector. EPA will solicit input from independent experts through a series of technical white papers, and in the fall of 2014, EPA will determine how best to pursue further methane reductions from these sources. If EPA decides to develop additional regulations, it will complete those regulations by the end of 2016.
Later in 2014, the BLM will propose updated standards to reduce venting and flaring from oil and gas production on public lands.
As part of the Quadrennial Energy Review, and through DOE-convened roundtables, the Administration will identify “downstream” methane reduction opportunities. Through the Natural Gas STAR program, EPA will work with the industry to expand voluntary efforts to reduce methane emissions.
