The Canadian and the UK governments launched the Powering Past Coal Alliance at the United Nations Framework Convention on Climate Change 23rd session of the Conference of the Parties (COP23), in Bonn, Germany, in November 2017.
There, 27 national, provincial, state and city governments endorsed the Declaration to support the phase-out of unabated coal power.
At the December 2017 One Planet Summit, the Alliance expanded further, adding 24 international organisations, investors, major consumer brands and generators of electricity. By supporting the transition from coal to clean power generation, these leading businesses are helping to move markets and increase financing for cleaner energy choices.
In April 2018 at the Bloomberg New Energy Finance Global Future of Energy Summit in New York, the co-founders of the Alliance, Ministers McKenna and Perry, signed a letter of collaboration with Bloomberg Philanthropies to support best practice approaches to the coal transition. In parallel, additional members joined the Alliance, bringing the total to 28 countries, eight sub-national governments, and 28 businesses.
At the September 2018 Global Climate Action Summit, a further 10 sub-national governments joined the alliance. They were closely followed by South Korea's Chungcheong province, the first Asian member, joining in early October.
