The US Environmental Protection Agency (EPA) has recently declared the repeal of greenhouse gas emission limits that were put in place during the Biden administration for coal- and gas-fired power plants. Additionally, it has unveiled a plan to dismantle the remaining climate emission standards applicable to the power sector. This decision marks a substantial rollback of US climate policy and has ignited widespread debate.

Power plants represent the second-largest contributor to greenhouse gas emissions in the US, trailing only behind the transportation sector. They are responsible for nearly a quarter of the country's total emissions. The repealed regulations mandated that coal-fired power plants either shut down by 2039 or implement technology to capture 90% of their emissions by 2032. Similarly, new gas-fired power plants would have been required to curtail emissions concurrently.

The EPA asserts that this policy shift could lead to savings of $310 billion for US households. However, environmental organizations and public health groups caution that it will inflict billions of dollars in damages on public health and the environment, while also intensifying global warming.

Analysts suggest that this regulatory rollback is closely linked to the burgeoning electricity demand in the US, particularly the escalating power requirements of AI data centers. Projections indicate that by 2030, data center electricity consumption in the US will constitute nearly 12% of the nation's total electricity usage, thereby imposing greater demands for a stable and uninterrupted power supply.
