On February 12, 2026, the US EPA officially rescinded the 2009 'endangerment finding' that classified greenhouse gases as threats to public health. This historic move marks the largest deregulatory action in US history, raising questions about its impact on climate policies, regulations, and the environment. Below, we explore what this change entails and how it might affect the future of climate action in the US.
-
Why did the US EPA rescind the 2009 climate finding?
The EPA's decision to rescind the 2009 endangerment finding was driven by a desire to reduce regulatory burdens and promote economic growth. The administration argues that the finding was based on controversial science and that removing it will lead to less government interference, lower costs for businesses, and increased energy independence.
-
How will this affect climate regulations and emissions standards?
With the rescission, federal greenhouse gas emissions standards for vehicles and power plants are at risk of being rolled back or eliminated. This could lead to increased emissions, less oversight of polluters, and a slowdown in efforts to combat climate change through federal regulation.
-
What are the legal challenges and environmental concerns now?
Environmental groups and some states are likely to challenge the EPA's decision in court, arguing it undermines decades of climate policy and scientific consensus. Critics warn that removing the endangerment finding could lead to higher pollution levels, worsening air quality, and greater climate-related risks.
-
What does this mean for US climate commitments?
The rescission could hinder the US's ability to meet international climate commitments, such as those under the Paris Agreement. It signals a shift away from federal leadership on climate issues, potentially impacting global efforts to limit warming and reduce greenhouse gases.
-
Could this decision be reversed in the future?
Yes, future administrations could restore the 2009 finding or establish new regulations based on scientific evidence. Legal challenges and political changes will play a significant role in determining whether this deregulatory move is permanent or temporary.
-
What are the economic arguments for and against the repeal?
Supporters claim that rescinding the finding will save Americans trillions in regulatory costs, boost economic growth, and promote energy independence. Opponents argue that the economic benefits are short-term and that the long-term costs of increased pollution and climate damage outweigh the savings.
