Marine Tondelier, the national secretary of the Ecologists, outlined the party's dual campaign—focused on both ecological priorities and political unity—during an event at the party's headquarters in Paris on September 3, 2026. Tondelier emphasized the urgency of "abolishing climate privileges," a term she used to describe the disproportionate environmental impact of wealthier individuals and corporations. As part of this effort, she proposed a 1% tax on the largest inheritances, those exceeding 4 million euros, which she estimated would generate 15 billion euros annually. This funding would be directed toward climate adaptation and resilience efforts, particularly in light of France's recent extreme weather events. Tondelier pointed to the record-breaking heatwave France experienced, which marked the hottest summer since temperature records began in 1900. She criticized the government's lack of preparedness, citing decisions such as the cancellation of orders for Canadair firefighting aircraft and the reduction of the Green Fund, a financial mechanism aimed at supporting environmental projects. She argued that these actions reflect a failure to take the climate crisis seriously and underscore the need for a broader ecological transformation to secure the future. In addressing criticism that ecologists are to blame for environmental issues, Tondelier defended the party’s stance, stating that ecological transformation is not only a moral obligation but also a prerequisite for true freedom. She emphasized the need to respect planetary boundaries, arguing that this is essential for long-term survival. Tondelier also highlighted the importance of economic restructuring, referencing past efforts in the Pas-de-Calais region to shift from coal to renewable energy, such as wind power. She stressed the need for unemployment compensation to support workers during this transition to new industries. Regarding France's debt, Tondelier noted that while the idea of canceling part of the country's debt with the European Central Bank (ECB) was discussed in 2020, she considered the proposal of canceling only France's debt as not credible. She called for a broader discussion on the ECB's role in the ecological transition, suggesting that the bank should penalize "brown assets"—those tied to fossil fuels—by excluding fossil fuel projects from loan guarantees. She also raised concerns about artificial intelligence (AI), urging an immediate moratorium on data center projects that do not ensure European sovereignty, and advocating for public control and European leadership in AI development. Tondelier criticized the current digital infrastructure for being fragile, authoritarian, and excessively resource-intensive, especially in the context of growing water scarcity.
