Drawing inspiration from the International Campaign to Ban Landmines — which spurred 164 nations to sign an international treaty banning the production, use, and stockpiling of landmines — and the Treaty on the Prohibition of Nuclear Weapons, the Fossil Fuel Non-Proliferation Treaty Initiative seeks to foster international cooperation. Its goal is to halt the expansion of oil, gas, and coal, phase out their existing production, and accelerate a fair and equitable transition to a fossil-free future. CIEL is a founding member and serves on the steering committee for the treaty. This initiative has gained tremendous support worldwide from a growing number of governments, parliamentarians, health professionals, Nobel Laureates, civil society organizations, and individuals. They all recognize the urgency of ending the fossil fuel era rapidly and equitably, while ensuring the well-being of workers, communities, and countries that rely on fossil fuels to create secure and healthy livelihoods.
