The United States (US) is facing the biggest environmental rollback in its history after a week of sweeping announcements from the Trump administration. Key agencies moved to weaken water protections, endangered species rules, and limits on offshore drilling, triggering public anger, praise from industry, and warnings of major legal battles ahead.
Below are the five biggest changes now underway, the data behind them, and voices reacting to the shift.
1. Up to 55 million acres of wetlands could lose federal protection
The Environmental Protection Agency (EPA) proposed a new definition of “waters of the United States” that removes federal safeguards from millions of wetlands and small streams. Environmental groups say the change could strip protection from up to 55 million acres, or roughly 85% of all wetlands nationwide.
The move weakens the 1972 Clean Water Act, which has long protected waterways from pollution. EPA officials argue the new rule provides “clarity” for farmers and developers.
2. Endangered Species Act changes could factor in economic losses
Federal wildlife agencies unveiled new rules allowing economic considerations, such as lost revenue from unused land, when deciding whether to list a species as endangered. Scientists warn this shifts the law away from biology and toward market interests. Pat Parenteau, a professor at Vermont Law and Graduate School, called the week “the week from hell for environmental policy,” warning of “irreparable harm.”
3. New offshore drilling plans cover 1.3 billion acres
The Interior Department proposed opening nearly 1.3 billion acres of U.S. coastal waters to oil and gas exploration.
As many as 34 lease sales could take place in areas including California, the Gulf of Mexico, and Alaska’s Arctic waters.
Industry groups welcomed the plan, saying it strengthens U.S. energy security. Environmental groups vowed to sue.
4. Clean energy offices removed from the Department of Energy
A revised Department of Energy (DoE) organizational chart dropped three major clean energy offices:
- The Office of Clean Energy Demonstrations
- The Office of Manufacturing and Energy Supply Chains.
- The Grid Deployment Office
These offices previously supported solar, wind, battery storage, and grid modernization projects. The cuts follow earlier moves by President Trump to remove Biden-era decarbonization funding.
5. Strong public support for protections sets stage for legal fights
While industries such as farming, oil, chemicals, and real estate back the rollbacks, public opinion leans the other way.
Polling from the International Fund for Animal Welfare shows:
- 4 in 5 Americans support the Endangered Species Act
- 81% are concerned about environmental and wildlife protection
Earthjustice attorney Kristen Boyles said, “Most people are not going to allow the sacrifice of our natural world to a bunch of billionaires and corporate interests.”
EPA Administrator Lee Zeldin defended the changes, saying he aims to write rules “durable enough to outlast future elections.” He added, “We will do more deregulation in one year than past governments have done across all agencies combined.”
A politically symbolic week
The policies were released as world leaders met at the COP30 climate summit in Brazil. President Trump became the first US president in 30 years not to attend, signalling his shift away from global climate diplomacy.
The administration says the changes support its “energy dominance” agenda focused on expanding fossil fuel production.
Environmental groups say the rollbacks violate long-standing federal obligations and promise to challenge each proposal in court.
Final decisions could take up to two years, and many cases may reach the Supreme Court.
For now, the United States enters a new era of environmental policy, one marked by fierce debate, sharp divisions, and a fight over the country’s natural future.
