The UK and Canada have joined with 24 other nations and regional states to launch a new global alliance aimed at phasing out coal-fired power and weaning the world off the most carbon intensive form of electricity generation. The new group was officially launched on the sidelines of the COP23 Summit in Bonn on Tuesday... The aim of the Alliance is to gain 50 national and regional signatories by the time of next year's UN climate change summit in Poland. Businesses are also being invited to formally signal their backing for the group and its goals... But while the new coalition will work with businesses, civil society, and governments to offer technical and practical help to accelerate the transition away from coal, the Alliance said it recognised that not all countries can completely phase out the use of unabated coal at the same rate... [and] that there needed to be a "just transition" to ensure workers in the coal sector were presented with new economic opportunities as the transition to cleaner energy continues.
