Trump's First Year: Rolling Back Environmental Regulations

President Trump's administration took a new approach to the environment and the management of EPA, reversing many of the decisions made by President Obama. His major policy decisions included leaving the Paris Climate Accord, reevaluating the Clean Power Plan, and cleaning up Superfund sites around the United States.

This is part of our series on Trump's first year, looking at foreign policy, the judiciary, energy and the environment and the economy.
