As the state returning officer announced in the early afternoon, participation in the “Berlin 2030 climate-neutral” referendum in the 2,208 polling stations was eleven percent nationwide by 12 p.m. It had previously been announced that 18.8 percent of those entitled to vote had been issued with voting cards that entitle them to vote by post or in advance in electoral offices.

The initiative is considered accepted if a majority of those voting and at least 25 percent of those entitled to vote vote yes. If both come about, an amendment to the Berlin Climate Protection Act with the advanced climate target would come into force immediately.

The current state government, on the other hand, is not aiming for climate neutrality until 2045. She does not consider the step to be feasible by 2030. "This Sunday we can make a one-off decision to do real climate protection," Fridays for Future Berlin campaigned for approval. The initiative was also supported by a call from Berlin artists.
