What Is Climate Change Policy and Why Is the US Falling Behind?

The United States has now withdrawn from the Paris Climate Agreement twice. In between, it rejoined, made significant domestic policy commitments, and began a partial energy transition.

In 2026, US climate policy is in its most confused state — with formal international disengagement, continued domestic clean energy growth from market forces and still-active tax credits, and escalating physical and economic consequences from climate change that don't pause for political cycles.

The Policy Whiplash

Obama: US joined the Paris Agreement in 2016, committed to 26-28% emissions reductions by 2025 (from 2005 levels), funded international climate adaptation through the Green Climate Fund.

Trump 1.0: Withdrew from Paris Agreement (effective 2020), reversed dozens of environmental regulations, expanded fossil fuel leasing.

Biden: Rejoined Paris Agreement on Day 1 (2021), passed the Inflation Reduction Act (IRA) with approximately $370 billion in clean energy tax credits and investments — the largest climate legislation in US history — and committed to 50-52% emissions reductions by 2030.

Trump 2.0: Withdrew from Paris Agreement again on Day 1 (2025), declared energy emergency, attempted to freeze IRA funding (partially blocked by courts and by Republican members of Congress who don't want to kill clean energy jobs in their districts).

The whiplash creates uncertainty for long-term investment planning, damages US credibility in international negotiations, and creates legal chaos for businesses that made multi-year commitments based on Biden-era policies.

Why IRA Tax Credits Are Hard to Kill

The Inflation Reduction Act passed in 2022 created tax credits for solar installation, wind energy, electric vehicles, battery manufacturing, and clean energy industry. These credits are already generating investment — over $300 billion in announced clean energy manufacturing in the US in 2022-2024.

The investment is disproportionately flowing to Republican-held districts in the Sun Belt and Midwest, where land is cheap and utilities are building large solar and wind projects.

Republican members of Congress from these districts have not supported repealing the IRA credits that are driving jobs and investment in their areas. This creates an unusual coalition: most Republicans support rolling back climate policy, but some Republicans protect the specific provisions that benefit their constituents.

The result: the IRA's market distortions continue largely intact even under a president hostile to climate policy, because the political economy of already-committed investment is powerful.

The China Clean Energy Reality

While the US debates policy, China has become the world's dominant clean energy manufacturing power:

• China produces approximately 80% of the world's solar panels
• China produces more than half of global wind turbines
• Chinese EV manufacturers (BYD, etc.) have become global competitors to US and European automakers
• China's installed solar and wind capacity exceeds the US by a wide margin and is growing faster

This creates a paradox for the Trump "America First" approach to energy: the clean energy transition is happening globally regardless of US policy. American firms compete in that transition or cede the market to China. Withdrawing from climate commitments doesn't stop the transition — it just determines who leads it.

Tariffs on Chinese solar panels and EVs are meant to protect US manufacturers. But those tariffs also raise the cost of clean energy deployment in the US, slowing a transition that has both climate and economic benefits.

The Physical Reality

Climate change is no longer primarily a future risk management problem. It is a current economic problem.

State Farm withdrew from California homeowner insurance market in 2023 due to wildfire risk. Multiple insurers have reduced or eliminated coverage in Florida for hurricane risk. Insurance markets in high-risk areas are either failing or being replaced by state-run last-resort insurers at much higher premiums.

The Federal Emergency Management Agency (FEMA) has had to request supplemental appropriations in multiple recent years as disaster costs exceed projections. The disasters aren't getting less expensive.

Agricultural regions in the American West are experiencing persistent drought. The Colorado River basin — water supply for 40 million people across seven states — is in multi-decade decline.

The question for US policy is not whether climate change has economic costs. Those costs are already appearing in insurance markets, disaster budgets, agricultural production, and infrastructure damage. The question is whether prevention is cheaper than adaptation and loss — and on that question, every mainstream economic analysis says yes.
