What is EPA Doing About Climate Change?
EPA is taking a number of common-sense steps to address the challenge of
climate change. Read asummary of EPA's efforts to reduce carbon pollutionin testimony by Gina McCarthy, Assistant Administrator for EPA's Office of Air and Radiation, to Congress on June 29, 2012.(16 pp,105 K,About PDF)
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. This report tracks annual U.S. greenhouse gas emissions since 1990.
TheGreenhouse Gas Reporting Programcollects 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-senseregulatory initiatives, to reduce GHG emissions and increase efficiency. For example, EPA'svehicle greenhouse gas rules, will save consumers $1.7 trillion at the pump by 2025, and eliminate six billion metric tons of GHG pollution.
Partnering With the Private Sector: Throughvoluntary 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.

Evaluating Policy Options, Costs and Benefits
EPA conducts economy-wide analyses to understand the economic impacts and effectiveness of proposed climate policies. Learn more aboutEPA's economic analyseson climate policies and the associated costs and benefits.
Advancing the Science
EPA contributes to world-class climate research through theU.S. Global Change Research Programand theIntergovernmental Panel on Climate Change.EPA'sOffice of Research and Developmentconducts 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 aboutEPA's International Climate Partnerships.
Partnering With States, Localities, and Tribes
EPA's State and Local Climate and Energy Programprovides technical assistance, analytical tools, and outreach support on climate change issues to state, local, and tribal governments.
Helping Communities Adapt
EPA'sClimate Ready EstuariesandClimate Ready Water Utilitiesprograms help coastal resource managers and water utility managers, respectively, plan and prepare for climate change. Learn more aboutEPA's efforts on adapting to climate change.
