The oil spilled from the tanker Solar 1 which sank in heavy seas off the Philippines on 11th August 2006. The vessel was chartered by Petron, the largest oil company in the Philippines and was carrying 2 million litres of Bunker Oil.
Greenpeace called on the Philippines government to hold the oil firm Petron and it's partners accountable for damages to the environment and people's livelihoods resulting from the worst oil spill in Philippine history.
