Democratic presidential candidate Joe Biden's "clean energy revolution" and climate goals stand in stark contrast with the policies President Donald Trump has pursued during his first term, underscoring the significant impact the presidential election will have on U.S. environmental and energy policy.

The congressional elections also will impact significantly the country's environmental and energy policy, as the next Congress can shape policy not just through its constitutional powers, but also through the reversal of many of the Trump administration's late-term rules via the Congressional Review Act.

In this three-part article, we outline both candidates' key environmental and energy policies, including how the candidates might — or might not — achieve their policy goals.

The first installment identifies the Trump administration's significant lateterm rules that a unified Democratic Congress may seek to invalidate to minimize Trump's legacy.

The second installment will analyze the policy differences between Trump and Biden on environmental issues including domestic energy, air quality and international climate diplomacy, and consider some likely consequences of those differences.

This third installment will cover the candidates' positions on water quality, biodiversity and federal lands, and environmental justice.


With two weeks remaining before the 2020 elections, both presidential candidates have had ample time to define the policy goals they would seek to accomplish in the energy and environmental space if elected. As he did during the 2016 campaign and throughout his first term in office, Trump has made statements espousing a commitment to environmental protection, as part of a broader focus on job growth and an America-centric "energy dominance." In practice, the Trump administration has altered the cornerstones of U.S. policy and regulatory approaches to climate change, air quality, clean water and other environmental priorities through administrative processes and in the courts.

Former Vice President Biden, on the other hand, has proposed a number of plans designed to build a "clean energy future," including, most notably, a goal to achieve a carbon pollution-free power sector by 2035. While many aspects of Biden's environmental goals reflect the policies of the Obama administration, Biden's proposals also reflect his campaign's messaging on climate change and environmental justice.

The Congressional Review Act

The candidates' proposed policies and the president's oft-touted regulatory rollbacks take center stage in public discussions, but a number of the Trump administration's environmental and energy accomplishments could be subject to the equivalent of a legislative veto from the next Congress via a unique legislative mechanism known as the Congressional Review Act.

Enacted in 1996, the CRA affords Congress the opportunity to reject by a simple majority vote of both chambers (with no filibuster available) any rule adopted by the executive branch, with one key limitation: The CRA applies only to rules finalized within 60 session days for the U.S. Senate or 60 legislative days for the U.S. House of Representatives before the date on which the previous Congress adjourned its final session.1

The temporal reach of the next Congress' authority to override a rule depends upon the date Congress adjourns at the end of this year, which means the CRA could reach back to rules finalized as early as May 20 of this year or as late as sometime last month.2 The CRA also contains a so-called lookback provision that resets the 60-day clock if Congress adjourns for the end of the year before the 60 days have tolled. In that case, the clock begins again on the 15th session day in the Senate and the 15th legislative day in the House.

Fully aware of the power of the CRA with a new president and Congress (the 115th Congress in 2017 overturned 15 Obama-era rules), the Trump administration worked feverishly over the last few months to finalize a number of significant rules that have reshaped both long-standing and recent U.S. environmental and energy policies.3

Among the rules that could be vulnerable under the CRA is a July final rule from the Council on Environmental Quality that reforms and expedites the National Environmental Policy Act process for reviewing projects with significant environmental impacts.4 Despite Trump's June executive order directing the heads of all agencies to identify ways to reduce the scope of or avoid entirely the NEPA review process in light of the COVID-19 pandemic, the administration may not have finalized the Council on Environmental Quality rule and other NEPA-related rules in time to avoid vulnerability under the CRA.5

Additionally, although regulations finalized prior to the CRA deadline ultimately may escape this quick demise from the next Congress, many tenets of the Trump administration's signature environmental and energy policies may be otherwise susceptible under a potential Biden presidency, the next Congress or both.

The CRA process becomes more important (or less so) depending upon the outcome of the congressional elections. Absent Democratic control of both the House and Senate, it is unlikely that Congress would be inclined to use this particular tool to overturn Trump administration regulations. Nevertheless, other tools are available through Congress' legislative powers (including the appropriations and budget process imbued in Congress' power of the purse) to alter or delay these Trump rulemakings when the next Congress convenes in January 2021.

Lastly, it is important to note that the Trump administration's most significant rules will continue to be litigated well beyond the 2020 elections.


1 5 U.S.C. § 801(d).

2 Given the House of Representative's 2020 calendar, the earliest possible date to which the provisions of 5 U.S.C. § 801(d) could extend is May 20, 2020. However, this date almost certainly will be pushed to a more recent date depending on the date on which Congress adjourns for the final time in 2020. Most often, this date takes place in June or July. See Daniel R. Perez, Upcoming CRA Deadline has Implications for Regulatory Oversight by Congress (Dec. 11, 2019), (providing overview of the CRA).
