Sign the fossil fuel non-proliferation treaty

Cardinal Michael Czerny, Prefect of the Vatican’s Dicastery for Promoting Integral Human Development, has expressed support for the fossil fuel non-proliferation treaty and announced last week that all new exploration and production of oil must be phased out to prevent global temperatures from rising to a “precipice.” 

Sign the treaty

This is why over 250,000 individuals, including Greta Thunberg, Cardinal Czerny, and me; more than 1500 organizations, including the Laudato Si Movement and; and 62 cities, including Paris, London, Geneva, and Yakima, Washington have signed the treaty. From the treaty’s website:

  • Climate change, like nuclear weapons, is a major global threat.
  • The main cause of the climate emergency is fossil fuels — responsible for 86% of all carbon dioxide emissions in the past decade.
  • Join them by endorsing the Fossil Fuel Non-Proliferation Treaty today.

Read more at, sign the treaty today, and continue your efforts to wean you and your family from fossil fuels! Then spread the word to others including your elected leaders and tell them you want them to sign the treaty and to double down on their efforts to stop the proliferation of fossil fuels and climate change. 

Working together, we can help take care of our common home.
