PROGRESS
18 governments from around the world are now joined together in a call for a global just transition to manage a fast, fair and fully financed phase out of oil, gas and coal via a Fossil Fuel Treaty
Building a bloc of nationsFossil fuels are the main driver of climate change, yet oil, gas and coal aren’t being directly addressed in UN climate negotiations, and there is no global plan to phase them out. Nations least responsible for carbon pollution are paying the biggest price when it comes to climate, health and security impacts.
A group of first mover nations have decided there is no time to waste. They support the three pillars of the proposed Fossil Fuel Treaty and are advocating for other nations to join them.
At UN climate meetings, one single country can veto action given the consensus model. That’s why these first movers are taking negotiations outside of UN processes so real progress can be made to determine how a just transition can take place, including the finance and legal mechanisms needed to ensure no country or community is left behind.
History proves that achieving a Fossil Fuel Treaty is possible. From landmines to ozone depleting chemicals - politics, economics and social norms can change when a group of first mover political leaders and countries, spurred on by civil society and ordinary people, decide to look at threats to humanity for what they are - and do something about it.
5 Phases towards a Fossil Fuel TreatyThese five phases outline the process of how we achieve a Fossil Fuel Treaty, from development and consensus building, to the final ratification and implementation of a final text.
-
In this first phase, the Fossil Fuel Treaty grew our campaign, through building support for the demand, engaging the public, key movements, civil society and media. The Treaty Initiative also enlisted our coalition and expert groups to design Treaty principles. Experts produced and expanded our research and evidence base that demonstrated a need for the phase out of fossil fuels.
-
In the second phase of the Initiative, we are working to build support from a bloc of first mover countries and UN agencies. This also includes building consensus in regional groupings such as the Pacific Islands Forum, Nordic Council, AOSIS, and CARICOM. The Fossil Fuel Treaty also is convening participating and observing nations in high-level dialogues.
-
In the third phase towards a Fossil Fuel Treaty, the Initiative will work on securing formal negotiating mandate inside or outside UN. There will also be convenings of working groups of diplomats.
-
The fourth phase of the Fossil Fuel Treaty centers around negotiations, which are likely to span several multi-week meetings over 12-24 months. During this phase, we will work to ensure the Treaty meets all 3 pillars and principles of the Initiative and finally the ratification of a treaty on fossil fuels.
-
The final phase of the process will include a monitor progress of three pillars, including via a Global Registry of Fossil Fuels. Additionally, the Initiative will work with ally countries and continue to bring more nations in to become members.

Antigua and Barbuda joined Timor-Leste to become the 7th and 8th nations calling for a Fossil Fuel Treaty in 2023, and the first countries outside of the Pacific region. The announcement was made from the stage of the Global Citizen Festival in New York in September 2023.
Hon. Gaston Browne, Prime Minister of Antigua and Barbuda, said in his speech:
"The climate crisis is the most existential threat facing all humanity. It doesn't distinguish between European forests and Caribbean waters. Some carry the burden more than others, as in the case of small Islands developing states. This is why today I'm honoured to announce that Antigua and Barbuda join our Pacific friends in calling for a negotiation of a Fossil Fuel Treaty."

Timor-Leste joined Antigua and Barbuda in the call for a Fossil Fuel Treaty in 2023, making it the 8th nation to do so. Timor-Leste was the first fossil fuel producing country to become part of the group of first mover nations.
H. E. José Ramos-Horta, President of Timor-Leste and and Nobel Peace Prize Laureate 1996, said:
"Our battle against climate change demands collective action. Fossil fuels are the chief culprits, so the world must move away from them. The climate crisis does not share blame equally among nations. Timor-Leste and fellow developing nations contribute the least to climate change, yet we bear the brunt of its immediate environmental and economic impacts. Timor-Leste stands in solidarity with Pacific nations and is formally joining the call for the negotiation of a Fossil Fuel Treaty. Its mission is simple — to halt new fossil fuel ventures, phase out existing ones and fund a fair shift to clean energy. It is more than a climate agreement between nations — it is a health, development and peace accord that can foster genuine well-being and prosperity for all."

Colombia and the Netherlands will host the First International Conference for a Phase-Out of Fossil Fuels in Santa Marta, Colombia, April 28-29, 2026. The conference will advance international cooperation on transitioning away from fossil fuel extraction — reinforcing the objectives of the Paris Agreement and aligning with the recent Advisory Opinion of the International Court of Justice, which confirmed that States have a legal obligation to protect the climate, including by addressing fossil fuel production, licensing and subsidies.
24 countries brought forward the Belém Declaration for a Phase-Out of Fossil Fuels at COP30 in November 2025. The declaration included a call for increased international dialogue and cooperation via the conference in Santa Marta.
Groundbreaking research from the Fossil Fuel Treaty Initiative gives insights on key areas that are relevant for nations, including research on revenue replacement, debt relief and multilateral cooperation.
