EPA is taking a number of common-sense steps to address the challenge of climate change.

Collecting Emissions Data

EPA collects various types of greenhouse gas emissions data. This data helps policy makers, businesses, and the Agency track greenhouse gas emissions trends and identify opportunities for reducing emissions and increasing efficiency.

• The Inventory of U.S. Greenhouse Gas Emissions and Sinks provides the United States' official estimate of total national-level greenhouse gas emissions.

  • June 2013 Climate Action Plan (PDF, 21pp , 318K)
  • March 2014 Strategy to Reduce Methane Emissions (PDF, 15pp, 2MB)
  • August 2014 Biogas Opportunities Roadmap
  • January 2015 Methane Strategy for Oil and Gas Sector
  This report tracks annual U.S. greenhouse gas emissions since 1990.
• The Greenhouse Gas Reporting Program collects and publishes emissions data from individual facilities in the United States that emit greenhouse gases in large quantities.

Getting Reductions

EPA is reducing greenhouse gas emissions and promoting a clean energy economy through highly successful partnerships and common-sense regulatory initiatives.

• Developing Common-sense Regulatory Initiatives: EPA is developing common-sense regulatory initiatives, to reduce GHG emissions and increase efficiency. For example, EPA's vehicle greenhouse gas rules will save consumers $1.7 trillion at the pump by 2025, and eliminate six billion metric tons of GHG pollution. EPA's Clean Power Plan addresses emissions from power plants,

  the largest source of carbon pollution in the country. When the Clean Power Plan is fully in place in 2030, carbon pollution from the power sector will be 32 percent below 2005 levels.
• Partnering With the Private Sector: Through voluntary energy and climate programs, EPA's partners reduced over 345 million metric tons of greenhouse gases in 2010 alone - equivalent to the emissions from 81 million vehicles - and saving consumers and businesses of about $21 billion.
• Reducing EPA's Carbon Footprint: EPA is monitoring emissions from its own energy use and fuel consumption and working to reduce greenhouse gas emissions by 25% by 2020. Learn more about federal greenhouse gas requirements and EPA's Strategic Sustainability Performance Plan.

Evaluating Policy Options, Costs and Benefits

EPA conducts economy-wide analyses to understand the economic impacts and effectiveness of proposed climate policies. Learn more about EPA's economic analyses on climate policies and the associated costs and benefits.

Advancing the Science

EPA contributes to world-class climate research through the U.S. Global Change Research Program and the Intergovernmental Panel on Climate Change Exit. EPA's Office of Research and Development conducts research to understand the environmental and health impacts of climate change and to provide sustainable solutions for adapting to and reducing the impact from a changing climate.

Partnering Internationally

EPA is engaged in a variety of international activities to advance climate change science, monitor our environment, and promote activities that reduce greenhouse gas emissions. EPA establishes partnerships, provides leadership, and shares technical expertise to support these activities. Learn more about EPA's International Climate Partnerships.

Partnering With States, Localities, and Tribes

EPA's State and Local Climate and Energy Program provides technical assistance, analytical tools, and outreach support on climate change issues to state, local, and tribal governments. See the progress made by our pilot communities.

Helping Communities Adapt

EPA's Climate Ready Estuaries and Climate Ready Water Utilities programs help coastal resource managers and water utility managers, respectively, plan and prepare for climate change. Learn more about EPA's efforts on adapting to climate change.
