The Impacts of Climate Change and the Trump Administration’s Anti-Environmental Agenda in Idaho

Idaho is under increasing threat from climate change, with two different $1 billion extreme weather events occurring from 2017 through 2019.

Just in the past three years, the Trump administration has attempted to roll back at least 95 environmental rules and regulations to the detriment of the environment and Americans’ public health. Moreover, the administration refuses to act to mitigate the effects of climate change—instead loosening requirements for polluters emitting the greenhouse gases that fuel the climate crisis. This dangerous agenda is affecting the lives of Americans across all 50 states.

Between 2017 and 2019, Idaho experienced two severe wildfires. The damages of these events led to losses of at least $1 billion.

Impacts of climate change

Extreme weather


  • Idaho currently experiences five days of dangerous heat per year, but this number is projected to double to nearly 10 days per year by 2050. This endangers the lives of the more than 40,000 people living in Idaho who are especially vulnerable to extreme heat.

Impacts of the Trump Administration’s anti-environmental policies


  • In March 2020, the Trump administration announced its final rule to overturn Obama-era fuel efficiency standards for cars. These weakened fuel standards will lead to higher greenhouse gas and particulate matter emissions and will cost Idaho residents nearly $56.6 million
  • The Trump administration is attempting to gut climate considerations from major infrastructure projects by eliminating the “cumulative impact” requirement of the National Environmental Policy Act. This is concerning because Idaho’s economy relies heavily on its tourism, agriculture, and outdoor recreation industries—all of which are highly dependent on climate and weather conditions and are threatened by the extreme weather events and higher temperatures driven by a changing climate.

Air quality

Water quality

  • Since 2019, the Trump administration has been in the process of weakening legislation regarding lead pipes. The proposed legislation gives companies twice as much time to remove lead pipes in systems testing for high lead levels. This is especially concerning in Idaho, which was recently named “the new Flint” regarding its dangerous levels of lead in water. A 2018 report found that 20 schools in Idaho’s capital city of Boise tested for high levels of lead. Furthermore, a historic building in Moscow, Idaho, tested positive for both lead and copper.
