Formula E is one of the greenest racing series in the world, as the cars the racers drive are all-electric, so it was curious when climate change protesters disrupted a race in Germany on Sunday.

Several white-shirted activists climbed the fences of the Tempelhof compound in Berlin and sat in front of cars already off the starting grid. Letzte Generation (Last Generation) posted a video of protesters disrupting the start of the race. The protesters were taken off the track by security guards.

“Time to slow down. Because we are on the road to climate hell with our foot on the gas,” the group said via Reuters.

A Formula E spokesman said the protest was «unrelated to the event».

«Security services stopped the outage quickly and safely,» the spokesman said. «The event was able to go ahead as planned.»
