Three young Canadians and two environmental organizations file a lawsuit in Canada against the federal government, arguing it is failing to develop or update a credible climate action plan to meet the country’s stated emissions goals for 2030. The plaintiffs include three young women, with announcements identifying Shirley Barnea from Quebec and Sophia Mathur from Ontario. The legal challenge asks the court to compel the government to “chart a credible, up-to-date course of action” and to take steps to protect Canadians from worsening climate impacts.

Multiple reports say the lawsuit is filed as Prime Minister Mark Carney’s government changes climate and energy priorities. AFP and other outlets describe that, since Carney takes office in March 2025, the administration rolls back or weakens several environmental measures, including a carbon tax for individuals and an emissions cap for the oil and gas sector. The government argues it is pursuing economic resilience amid trade tensions with the United States by accelerating major energy and infrastructure projects.

The plaintiffs point to Canada’s climate targets, including an earlier commitment under Justin Trudeau to cut total carbon emissions 40–45% below 2005 levels by 2030, while noting Carney has acknowledged the target is unlikely to be met. Related climate litigation is also reported in Canada.
