Climate Policy

Climate policy covers the choices governments make about whether and how to reduce greenhouse gas emissions, adapt to a changing climate, and manage the economic and international relationships tied to energy use. In the United States, this work is split across Congress, federal agencies like the EPA and Department of Energy, the courts, and international negotiations, with states and cities often setting their own rules on top of federal baselines.

Working with other countries is a core piece of the puzzle, since greenhouse gases cross borders and no single nation can address climate change alone. The International Climate Agreements category explains how the United States joins, negotiates, and sometimes withdraws from these pacts, and what is at stake for American funding and influence when it does.

Domestic rules and institutions shape how climate goals translate into everyday policy, from vehicle standards to home appliances to the White House offices that coordinate environmental review. Federal Climate Policy covers these mechanics, while How Earth Day Inspired the White House’s Environmental Watchdog traces how the modern system of environmental oversight came to exist.

Economic tools and targets are where much of the policy debate plays out. Carbon Pricing looks at putting a cost on emissions through taxes or trading systems, while Emissions Reduction Strategies covers regulatory approaches agencies use to cut pollution over time. These questions increasingly overlap with broader concerns about national resilience, as described in Why Climate Change Is Now Treated as a National Security Threat.
