US ends limits on coal and gas plant emissions, removing key tool to battle climate crisis

# Why This Matters The EPA's repeal of emission limits for coal and gas plants represents a fundamental retreat from the regulatory infrastructure designed to curb the power sector's carbon output, which accounts for roughly 25% of U.S. greenhouse gas emissions. By eliminating these standards, the administration has removed one of the most direct mechanisms for forcing utilities to invest in cleaner technologies or reduce generation from fossil fuels, effectively rolling back years of incremental progress toward meeting climate targets. The practical consequence will likely be continued reliance on older, dirtier coal plants that utilities might otherwise have retired, while reducing market incentives for renewable energy investment. For states, cities, and companies that have committed to their own climate goals, this federal action eliminates a backstop that previously pushed compliance across state lines, making those pledges significantly harder to achieve without additional regulation at the state level or through market-driven corporate decisions.
