In 2022, France promised 1 billion trees within a decade; four years later, a court...

France's Council of State struck down Decree No. 2025-401 on 15 July 2026, which funded the one billion trees in ten years plan.

The court ruled that the decree violated France's Environmental Charter because the public was not consulted before adoption.

State subsidies covering 40% to 65% of forest renewal costs were deemed to significantly impact biodiversity, soil health, and wildfire risks.

Environmental group Canopée brought the case; its separate challenge to a related administrative order was rejected as filed after the legal deadline.

France's High Council for Climate reported that 21% of forest plantations failed completely in 2025 due to severe drought.
