A group of climate activists walked out of a panel at the U.N. climate summit in Madrid, Spain on Thursday to protest the presence of Shell, BP and Chevron.

Representatives from the oil companies were taking part in an event organized by the International Emissions Trading Association.

This comes as the Spanish government is facing criticism for reaching out to Endesa, Spain’s biggest corporate greenhouse gas polluter, to sponsor the U.N. climate talks.
