Full Expensing Is Pro-Growth, Pro-Environment Policy

Introduction

In this joint white paper, Nick Loris—Executive Vice President of Policy at C3 Solutions—and Josh T. Smith—energy‑policy lead at the Abundance Institute and visiting fellow with C3—propose replacing today’s patchwork of clean‑energy tax credits with permanent, economy‑wide full expensing for all new capital investments and R&D. Immediate expensing lets businesses deduct the entire cost of plant, equipment, and research in the year the spending occurs, eliminating multi‑year depreciation schedules that discourage up‑front investment. By giving every industry—from advanced manufacturing to next‑generation clean energy—the same neutral tax treatment, the authors argue, Congress can spur broad‑based private investment without picking winners or losers.

The analysis shows full expensing delivers more growth per federal dollar than targeted subsidies while still advancing environmental goals. Tax‑Foundation modeling suggests a permanent policy would boost long‑run GDP by roughly 1.8 percent, create hundreds of thousands of jobs, and strengthen U.S. competitiveness, all at just over one‑quarter the projected ten‑year cost of maintaining Inflation Reduction Act credits. Because every sector can claim the deduction, immediate expensing also offers a politically viable swap: lawmakers can phase down ballooning subsidies yet remain pro‑investment and pro‑environment, giving businesses the long‑term certainty they need to build America’s cleaner, more prosperous energy future.

Federal Critical Minerals Investments Need a Cost-Benefit Test

Last week, the Trump Administration announced more than $2 billion in new federal money for battery and critical minerals companies. The largest piece was a $1.4 billion loan to the silicon-anode battery maker Sila Nanotechnologies, alongside smaller deals for a scandium mine, a rare-earth-free magnet maker, a direct government ownership stake in a bauxite company, and grants for mining schools. It is the latest in a long series of federal investments; by the administration’s own count, it has signed or approved minerals deals worth nearly $40 billion since taking office.

We Know How to Reduce Wildfire Risk. Policy Is Standing in the Way

Over the past few weeks, smoky skies have spread across the United States and Canada. From the Canadian fires that pushed the Northeast and Great Lakes air quality to dangerous levels last month to the fires burning in the Northwest today, there seems to be no end in sight. The need to reduce fire risk is apparent, and we know how to do so through active forest management. Yet policy continues to slow those efforts down and that urgently needs to change.

Federal Grid Reforms Pick the Right Route and the Wrong Builder

America’s power grid is really a patchwork of regional grids, each with their own operators, with few high-capacity lines connecting them. This fragmentation comes at a real cost for customers, who are often unable to access cheaper power available just across a state or regional border. The Department of Energy’s recent National Transmission Needs Study identifies several of these cases, where regions’ electricity costs would decline substantially if they were connected by a high-capacity transmission line. Providing these benefits to consumers, however, requires confronting not just the incentives that discourage utilities from building interregional lines, but the state laws that let incumbent monopolies control who builds them.
