Air pollution and emissions
Completed
1. Weakened Obama-era fuel economy and greenhouse gas standards for passenger cars and light trucks.
2. Revoked California’s power to set stricter tailpipe emissions standards than the federal government.
3. Withdrew the legal justification for an Obama-era rule that limited mercury emissions from coal power plants.
4. Replaced the Obama-era Clean Power Plan, which would have set strict limits on carbon emissions from coal- and gas-fired power plants, with a new version that would let states set their own rules.
5. Canceled a requirement for oil and gas companies to report methane emissions.
6. Revised and partially repealed an Obama-era rule limiting methane emissions on public lands, including intentional venting and flaring from drilling operations.
7. Loosened a Clinton-era rule designed to limit toxic emissions from major industrial polluters.
8. Revised a program designed to safeguard communities from increases in pollution from new power plants to make it easier for facilities to avoid emissions regulations.
9. Amended rules that govern how refineries monitor pollution in surrounding communities.
10. Weakened an Obama-era rule meant to reduce air pollution in national parks and wilderness areas.
11. Weakened oversight of some state plans for reducing air pollution in national parks.
12. Relaxed air pollution regulations for a handful of plants that burn waste coal for electricity.
13. Repealed rules meant to reduce leaking and venting of powerful greenhouse gases known as hydrofluorocarbons from large refrigeration and air conditioning systems.
14. Directed agencies to stop using an Obama-era calculation of the social cost of carbon that rulemakers used to estimate the long-term economic benefits of reducing carbon dioxide emissions.
15. Withdrew guidance directing federal agencies to include greenhouse gas emissions in environmental reviews. But several district courts have ruled that emissions must be included in such reviews.
16. Revoked an Obama executive order that set a goal of cutting the federal government’s greenhouse gas emissions by 40 percent over 10 years.
17. Repealed a requirement that state and regional authorities track tailpipe emissions from vehicles on federal highways.
18. Lifted a summertime ban on the use of E15, a gasoline blend made of 15 percent ethanol. (Burning gasoline with a higher concentration of ethanol in hot conditions increases smog.)
19. Changed rules to allow states and the E.P.A. to take longer to develop and approve plans aimed at cutting methane emissions from existing landfills.
In progress
20. Submitted notice of intent to withdraw the United States from the Paris climate agreement. (The process of withdrawing cannot be completed until November 2020.)
21. Proposed relaxing Obama-era requirements that companies monitor and repair methane leaks at oil and gas facilities.
22. Proposed eliminating Obama-era restrictions that, in effect, required newly built coal power plants to capture carbon dioxide emissions.
23. Proposed revisions to standards for carbon dioxide emissions from new, modified and reconstructed power plants.
24. Began a review of emissions rules for power plant start-ups, shutdowns and malfunctions. One outcome of that review: In February 2020, E.P.A. reversed a requirement that Texas follow emissions rules during certain malfunction events.
25. Opened for comment a proposal limiting the ability of individuals and communities to challenge E.P.A.-issued pollution permits before a panel of agency judges.
26. Delayed issuing a rule limiting greenhouse gas emissions from aircraft. (The E.P.A. acknowledged it is legally required to issue the rule, but has not done so yet. The delay is being challenged by environmental groups.)
27. Proposed limiting pesticide application buffer zones that are intended to protect farm workers and bystanders from accidental exposure.
Drilling and extraction
Completed
28. Made significant cuts to the borders of two national monuments in Utah and recommended border and resource-management changes to several more.
29. Lifted ban on drilling in the Arctic National Wildlife Refuge.
30. Rescinded water pollution regulations for fracking on federal and Indian lands.
31. Scrapped a proposed rule that required mines to prove they could pay to clean up future pollution.
32. Withdrew a requirement that Gulf oil rig owners prove they can cover the costs of removing rigs once they stop producing.
33. Approved construction of the Dakota Access pipeline less than a mile from the Standing Rock Sioux Reservation after the Army Corps of Engineers had said it would explore alternative routes. (A court has since ruled the agency must investigate how the pipeline is impacting the environment and local tribes, but it can continue to operate in the meantime.)
34. Changed how the Federal Energy Regulatory Commission considers the indirect effects of greenhouse gas emissions in environmental reviews of pipelines.
35. Revoked an Obama-era executive order designed to preserve ocean, coastal and Great Lakes waters in favor of a policy focused on energy production and economic growth.
36. Permitted the use of seismic air guns for gas and oil exploration in the Atlantic Ocean. The practice, which can kill marine life and disrupt fisheries, was blocked under the Obama administration.
37. Loosened offshore drilling safety regulations implemented by the Obama after following the 2010 Deepwater Horizon explosion and oil spill, including reduced testing requirements for blowout prevention systems.
38. Lifted an Obama-era freeze on new coal leases on public lands. In April 2019, a judge ruled that the Interior Department could not begin selling new leases without completing an environmental review. In February, the agency published an assessment that concluded restarting federal coal leasing would have little environmental impact.
In progress
39. Proposed opening most of America’s coastal waters to offshore oil and gas drilling but delayed the plan after a federal judge ruled that Mr. Trump’s reversal of an Obama-era ban on drilling in the Atlantic and Arctic Oceans was unlawful.
40. Repealed an Obama-era rule governing royalties for oil, gas and coal leases on federal lands, which replaced a 1980s rule that critics said allowed companies to underpay the federal government. A federal judge struck down the Trump administration’s repeal. The Interior Department is reviewing the decision.
41. Proposed revising regulations on offshore oil and gas exploration by floating vessels in the Arctic that were developed after a 2013 accident. The Interior Department previously said it was “considering full rescission or revision of this rule.”
42. Proposed “streamlining” the approval process for drilling for oil and gas in national forests.
43. Recommended shrinking three marine protected areas or opening them to commercial fishing.
44. Proposed opening more land in the Alaska National Petroleum Reserve for oil drilling. The Obama administration had designated about half of the reserve as a conservation area.
45. Proposed lifting a Clinton-era policy that banned logging and road construction in Tongass National Forest, Alaska.
46. Approved the Keystone XL pipeline rejected by President Barack Obama, but a federal judge blocked the project from going forward without an adequate environmental review process. Mr. Trump later attempted to sidestep the ruling by issuing a presidential permit. Initial construction has started, but the project remains tied up in court.
Infrastructure and planning
Completed
47. Revoked Obama-era flood standards for federal infrastructure projects that required the government to account for sea level rise and other climate change effects.
48. Relaxed the environmental review process for federal infrastructure projects.
49. Revoked a directive for federal agencies to minimize impacts on water, wildlife, land and other natural resources when approving development projects.
50. Revoked an Obama executive order promoting climate resilience in the northern Bering Sea region of Alaska, which withdrew local waters from oil and gas leasing and established a tribal advisory council to consult on local environmental issues.
51. Reversed an update to the Bureau of Land Management’s public land-use planning process.
52. Withdrew an Obama-era order to consider climate change in the management of natural resources in national parks.
53. Restricted most Interior Department environmental studies to one year in length and a maximum of 150 pages, citing a need to reduce paperwork.
54. Withdrew a number of Obama-era Interior Department climate change and conservation policies that the agency said could “burden the development or utilization of domestically produced energy resources.”
55. Eliminated the use of an Obama-era planning system designed to minimize harm from oil and gas activity on sensitive landscapes, such as national parks.
56. Withdrew Obama-era policies designed to maintain or, ideally, improve natural resources affected by federal projects.
In progress
57. Proposed plans to speed up the environmental review process for Forest Service projects.
Animals
Completed
58. Changed the way the Endangered Species Act is applied, making it more difficult to protect wildlife from long-term threats posed by climate change.
59. Relaxed environmental protections for salmon and smelt in California’s Central Valley in order to free up water for farmers.
