Exclusive - Britain, Canada ally to boost support for global coal phase-out

Britain and Canada will urge nations at U.N. climate talks on Thursday to join them in a global alliance to phase out coal, a letter seen by Reuters shows, defying U.S. lobbying in favour of the fossil fuel at the same event.Since the signing of the Paris Agreement in 2015, which aims to wean the world economy off fossil fuels, several countries have pledged to phase out coal, including Britain, Canada, France and the Netherlands.
