Climate change is real and happening all around us. Taking action to fight the urgent threat of climate change offers an opportunity to build more resilientinfrastructure, protect public health, advance environmental justice, strengthen America'sworking communities, and spur American technological innovations.
EPA's work is improving society’s understanding of climate change and its impacts on human health and the environment. The data, tools, and resources that EPA develops can also be used by other agencies, organizations, states, Tribes, and communities to help tackle the climate crisis effectively, equitably, and sustainably.

Measuring Emissions Data
EPA is responsible for measuring greenhouse gas emissions using two programs designed to help the public and policymakers understand the nation’s total emissions as well as the sources and types of these emissions at individual facilities.
Reducing Emissions
EPA works with industry and others to reduce greenhouse gas emissions through regulatory initiatives and partnership programs. Within the Agency, EPA implements a range of strategies to reduce its own greenhouse gas emissions, increase energy efficiency, and take other steps to reduce its carbon footprint.
Investing in Our Future
EPA is making historic investments to tackle climate change, protect public health, create jobs in communities across the country, and deliver a more equitable future.
Evaluating Policy Options, Costs, and Benefits
EPA conducts analyses to understand the physical and economic impacts of climate change under different emission scenarios and to quantify the economic impacts and effectiveness of proposed climate policies. EPA also provides free tools to state, local, and Tribal governments to help them evaluate their own clean energy policies and programs.

EPA’s Participation in the U.S. Global Change Research Program
EPA is one of 13 federal government agencies working as part of the U.S. Global Change Research Programto help the world understand, assess, and respond to global change. EPA participates in the Sustained Assessment Working Group and contributes to the program's development of the National Climate Assessment.
Advancing the Science
EPA conducts research on climate change to understand its impacts and help manage its risks. EPA partners with other federal agencies and international organizations to coordinate research. EPA’s research includes efforts to better understand the links between climate change and air quality, ecosystems, and human health.

WildfireResearch and Toolbox
Wildfires are increasing, in part because of climate change.EPA is conducting research to advance understanding of wildfire smoke impacts and protect public health.Learn about actions people can take to reduce their risks from smoke exposure with EPA’s Smoke-Ready Toolbox for Wildfires.
Partnering Internationally
EPA is engaged in a variety of international activities to advance climate change science, monitor the environment, and promote activities that reduce greenhouse gas emissions. EPA establishes partnerships, provides leadership, and shares technical expertise to support these activities.
Helping Communities Reduce Emissions and Adapt
Climate change is happening and affecting communities, livelihoods, and environments. In response, EPA is providing technical assistance, tools, and resources to help state, Tribal, and local governments in planning, adapting, and building climate resiliency.
