This week, the leaders of the Group of Seven (G7) economies — Canada, France, Germany, Italy, Japan, the United Kingdom and the United States, plus the European Union — will assemble in Hiroshima, Japan, for their 49th summit. Climate action will, rightly, be high on the agenda. With climate impacts mounting and the transition to low-carbon energy at a crossroads, the group must make sure that the action it takes is swift and decisive, and works both in its member countries’ best interests and in those of the wider world.
