For nearly two decades, the Endangerment Finding served as the legal bedrock of American climate policy, compelling the Environmental Protection Agency to treat carbon pollution as a threat to human survival. Today, that foundation is gone. Following the Trump administration's landmark repeal, the very framework used to regulate US emissions has vanished.

In this episode of Climate Court Voices, Noah Perch-Ahern, an attorney at Greenberg Glusker LLP, joins us to break down the fallout, from the firestorm of litigation hitting the courts to the sudden, high-stakes shift toward a patchwork of state-level regulations.

In 2015, a Dutch court became the first in the world to order a government to take stronger action on climate. Since then, climate litigation has evolved into a global accountability system used by private actors, civil society and individuals locally, regionally, nationally and internationally to hold governments and corporate polluters accountable.

In this episode of Climate Court Voices, Lucy Maxwell, Co-Director of the Climate Litigation Network, helps us understand how a surge in climate lawsuits in the past decade has forced governments to set clear rules for national climate action, influenced public opinion, and reshaped how investors and regulators perceive climate risk. She discusses key court battles and the legal building blocks they have established, how corporate climate litigation is beginning to catch up, and what cases we should look out for in 2026.

In 2016, the KlimaSeniorinnen – an association of over 2,000 senior Swiss women – launched a legal challenge against their government, alleging that inadequate climate policies violated their fundamental human rights. After years of dismissals in domestic courts, the group secured a landmark victory at the European Court of Human Rights in April 2024. The ruling was unprecedented, marking the first time an international court has recognized that state climate inaction constitutes a human rights violation.

In this episode of Climate Court Voices, we sit down with Elisabeth Stern, a cultural anthropologist and board member of KlimaSeniorinnen. Elisabeth shares the group's journey from grassroots organization to legal pioneers, detailing the dismissals they faced at home and the ongoing uphill battle to ensure the Swiss government turns this historic judgment into tangible climate action.
