• 23 states led by California and New York sue Trump over climate regulations.
• The lawsuit addresses the revocation of the "endangerment finding" from 2009.
• Critics argue the decision undermines public health and increases pollution.
• The Trump administration maintains that the repeal benefits the economy.
• Similar lawsuits have been filed by environmental organizations.

A coalition of 23 states, primarily led by California and New York, has filed a lawsuit against President Donald Trump's administration in response to the decision to revoke the "endangerment finding" that underpins critical climate regulations. This action, lodged in the U.S. Court of Appeals for the District of Columbia, challenges the Environmental Protection Agency's (EPA) move to revoke a 2009 conclusion that asserts greenhouse gases endanger public health and the environment, according to Al Jazeera and Reuters.

The lawsuit also contests the EPA's decision to eliminate federal rules that limit greenhouse gas emissions from vehicles, which affects models from 2012 to 2027. Attorney General Letitia James of New York stated, "Instead of helping Americans face our new reality, the Trump administration has chosen denial," highlighting the potentially devastating impacts on public health and climate initiatives, according to BBC and Reuters.

Environmental advocates argue that rolling back the "endangerment finding" could lead to increased health risks and pollution levels, affecting millions across the country. Critics of the Trump administration's decisions assert that this reversal will elevate gasoline prices and could impose additional costs on U.S. drivers, potentially reaching over $3 billion annually by 2035, as suggested by environmental groups challenging the rollback, according to Al Jazeera and BBC.

President Trump has positioned the revocation as a necessary step to enhance the economic viability of the fossil fuel industry, which he accuses Democrats of hindering through excessive regulations. The president has characterized the previous climate policies as detrimental to the economy, describing them as a "disastrous Obama-era policy" while calling for a "victory" over what he terms radical energy measures established by his predecessors, according to Reuters and BBC.
