24 February: Researchers Brick Medak and Felix Heilmann of think tank E3G call on German chancellor Merkel to take the reins on Nord Stream 2, agree a moratorium on the construction and organise a summit with key actors Russia, the U.S., Ukraine, eastern European countries, the European Commission, the companies involved and civil society. “Now is the time for diplomacy,” they write in an op-ed in Tagesspiegel Background. Parallel to the summit, an international panel of experts should be commissioned to shed light on the energy and climate policy background of the pipeline in a study, they say.
