The return to the Paris Agreement and the appointment of John Kerry as the new US Special Presidential Envoy for Climate, with promises to work closely with allies on all energy and climate matters, indicate a new paradigm: international energy and climate cooperation is again back on the agenda. The days of the Trump administration’s “energy dominance” approach seem to be over. That is great news for the global climate movement, but also for friends and allies across the world. But so far, these are just declarations and intentions. The new president will likely meet a lot of opposition in Congress, as well as from the powerful shale gas and oil lobbies. Also, climate activists probably will not be happy with all of President Biden’s ideas. For example, his renewed interest in modern nuclear power as a clean energy source might not please everyone in the European Union (EU), especially not Germany. Nevertheless, hopes are up for a transatlantic New Energy Deal between the United States and the EU in light of new policy substance with ambitious climate targets, and a new tone.
