British oil giant BP said Wednesday that it will quit three US-based trade bodies as part of a review of climate policy under new chief executive Bernard Looney. "BP today announced that ... it will leave three US-based organisations -- American Fuel and Petrochemical Manufacturers, the Western States Petroleum Association and the Western Energy Alliance," it said in a statement. The London-listed energy major added that the move followed "an in-depth review examining the alignment of the climate-related policies and activities of trade associations with BP's positions". Wednesday's announcement came two weeks after Looney declared that BP aimed to achieve "net zero" carbon emissions by 2050 -- but gave no detail on how it planned to hit the target. BP had also forecast earlier this month that traditional oil and gas production would decline gradually as cleaner energy output increases. "BP will pursue opportunities to work with organisations who share our ambitious and progressive approach to the energy transition," Looney added on Wednesday. "And when differences arise we will be transparent. But if our views cannot be reconciled, we will be prepared to part company." BP still however belongs to 30 trade associations around the world, including the powerful American Petroleum Institute. Wednesday's news was ridiculed by environmental campaign group Greenpeace. "Judge a company by the company they keep," said Mel Evans, climate campaigner for Greenpeace UK. "BP are sticking with the American Petroleum Institute, the lobby group who wrecked Obama's methane restrictions." She added: "This report appears to be tokenistic, inadequate and hypocritical -- like all of BP's climate plans that we've seen so far." jbo-rfj/rl
