Voters in Berlin go to the polls this weekend to decide on a proposal that would force the city government to drastically ramp up the German capital’s climate goals.
Sunday's referendum, which has attracted considerable financial support from U.S.-based philanthropists, calls for Berlin to become climate neutral by 2030, meaning that within less than eight years the city would not be allowed to contribute further to global warming. An existing law sets the deadline for achieving that goal at 2045, which is also Germany's national target.
