In the heart of Montana, a young climate activist, Eva Lighthiser, is making waves with her lawsuit against the US President, Donald Trump. Her story is not just about legal battles; it's a testament to the power of youth activism and the urgent need to address the climate crisis. As a 20-year-old, Eva is challenging the very foundations of her state's policies, which she believes are endangering her future and that of her generation. But what makes her journey truly remarkable is the personal growth and the sense of community she has cultivated along the way.
Eva's affinity for the natural world is deeply rooted in her upbringing. Growing up in Livingston, Montana, she developed a profound connection with the outdoors, often camping and climbing mountains. However, it was her involvement in youth-led climate litigation that truly shaped her path. In early 2020, she learned about Our Children's Trust, a non-profit law firm advocating for environmental justice. The idea of youth-led litigation resonated with her, and she became a plaintiff in Held v Montana, a case challenging the state's pro-fossil fuel policies. This experience not only taught her about the legal system but also about the power of collective action.
The Held v Montana case, which went to trial in 2023, was a groundbreaking win for the plaintiffs. It demonstrated the potential for young people to hold governments accountable for their environmental actions. However, Eva's journey didn't stop there. In early 2025, she was approached about becoming the lead plaintiff in Lighthiser v Trump, a federal lawsuit challenging the Trump administration's pro-fossil fuel policies. This was a moment of clarity for her, as she realized the magnitude of her challenge.
The lawsuit, Lighthiser v Trump, is a bold move, employing sweeping arguments to block several pro-fossil fuel executive orders. While it has faced legal challenges, Eva remains steadfast in her belief that such litigation is necessary to push the courts forward. She sees it as a way to educate judges about the climate harms facing young people and to force the government to acknowledge its role in causing harm.
Eva's personal growth is evident in her ability to mentor younger plaintiffs and unite young environmentalists. Jorja McCormick, a 17-year-old plaintiff in the Lighthiser lawsuit, credits Eva for making the legal process seem approachable. Eva's mother, Erica, is proud of her daughter's impact but worries about the scrutiny the lawsuit could bring, especially from a president who seems to prioritize retribution against his critics.
Despite the challenges, Eva remains optimistic. She believes that youth-led climate litigation is essential to pushing the courts forward and that bold actions are necessary to create change. In her words, 'There are risks. But if you never take risks, nothing good happens.' Her story is a powerful reminder of the potential for young people to drive meaningful change and to hold those in power accountable for their actions.
