SFP_pollution_graphic_1920x1080x_edited

April 29, 2025: Trump’s first 100 days in office have been the most harmful 100 days of any administration for climate, clean energy, public health, and communities, especially our most vulnerable communities. During its first 100 days, the Trump administration’s actions have accelerated the climate crisis and endangered communities’ health, driven up costs and undermined economic growth. The rollbacks tracked below – cuts to extreme weather preparedness, frozen investments, and blocked pollution protections, and more – will have a devastating impact that lasts far beyond 100 days.

Trump’s 100 Days, 100 Harms is an attempt to paint a picture of the pain the new administration has already inflicted on the climate, economy, health, and wellbeing of the American people.
