This week, Sloan Speck (Colorado, Google Scholar) reviews a new work by Roberta F. Mann (Oregon, SSRN) & Tracey M. Roberts (Samford, Google Scholar), The Long and Winding Road: The Inflation Reduction Act’s Energy and Environmental Tax Credits, 78 Nat’l Tax J. 223 (2025) (download here).
The Inflation Reduction Act of 2022 introduced a generational suite of energy and environmental tax credits. Then, in July 2025, the One Big Beautiful Bill Act rolled back many of these credits, most notably for consumers, in an explicitly partisan rebuke of the IRA’s ambitious climate change goals. In this context, it’s worth revisiting Roberta Mann and Tracey Roberts’s recent National Tax Journal article, The Long and Winding Road: The Inflation Reduction Act’s Energy and Environmental Tax Credits, which details the history and political economy of these types of tax benefits to show both continuity and change in the IRA’s pathbreaking package.
From the perspective of Mann and Roberts’s insightful article, the OBBBA may illustrate yet another kink in the United States’ uneven path toward—and often-ambivalent relationship with—environmental stewardship. Published before the OBBBA, Mann and Roberts’s article treats the IRA’s tax credits not as a self-contained policy program, but as an episode in a longer story about the American state, the political economy of energy, and the tax system’s peculiar capacity to do public work indirectly. The OBBBA simply is the next chapter in this tale. More crucially, however, Mann and Roberts give a foundation for understanding the OBBBA as a predictable reversion to the policy mean—as a legislative move that preserves important parts of the IRA’s legacy while reinscribing the fiscal caution, entrenched interests, and political constraints that have characterized U.S. environmental policy since the 1970s.
