Since taking office last year, President Trump has made eliminating federal regulations a priority. His administration, with help from Republicans in Congress, has often targeted environmental rules it sees as overly burdensome to the fossil fuel industry, including major Obama-era policies aimed at fighting climate change.

To date, the Trump administration has sought to reverse more than 70 environmental rules, according to a New York Times analysis, based on research from Harvard Law School’s Environmental Regulation Rollback Tracker, Columbia Law School’s Climate Tracker and other sources.

The Environmental Protection Agency has been involved in more than a third of the policy reversals identified by The Times. Scott Pruitt, the head of the E.P.A. who spearheaded the administration’s agenda of environmental deregulation, resigned after facing a number of ethics scandals. Andrew Wheeler, the new acting chief of the agency, is a former coal lobbyist who also wants to roll back environmental regulations.

Rules targeted for reversal so far include key Obama-era efforts to curb planet-warming greenhouse gas emissions, as well as broader air and water pollution controls and protections for threatened animals and habitats. The Trump administration has, in many instances, pared back these regulations in favor of more expansive energy extraction policies — often as a direct response to petitions from oil, gas and coal companies. Mr. Trump has argued that supporting the fossil fuel industry strengthens the economy.

The list above represents two types of policy changes: rules that have been officially reversed and those still in progress. Other rules, summarized at the bottom of this page, were undone but later reinstated after legal challenges.

The process of rolling back regulations has not always been smooth, in part because the administration has in some cases skipped steps like notifying the public and asking for comment. In several cases, courts have been asked to intervene to get agencies to follow their own policies.

All told, the Trump administration’s environmental rollbacks could lead to at least 80,000 extra deaths per decade and cause respiratory problems for more than one million people, according to a recent analysis conducted by researchers from Harvard University. That number, however, is likely to be “a major underestimate of the global public health impact,” said Francesca Dominici, a professor of biostatistics at the Harvard School of Public Health.
