The activists unfurled banners with the message: "Cancelled: Climate Risk", and held up photos of 30 Greenpeace activists currently jailed in Russia.
"This is part of a long fight to save the climate and the Arctic," Truls Gulowsen, the programme Manager for Greenpeace in Norway, said in a speech to the conference. "As long as the oil industry continues its greedy hunt for Arctic oil that the planet cannot afford to burn, we will use any opportunity we get to keep telling them the truth."
After twenty minutes, a squad of ten police arrived in the hotel and escorted the activists from the building. No arrests have been made.
