Shell documents show years of Nigeria pipeline pumping despite pollution warnings

British multinational Shell continued operating a major oil pipeline in Nigeria for years even though internal documents show it knew the line was causing widespread pollution. The disclosure centres on the Nembe Creek Trunk Line, a 60-mile pipeline in the Niger Delta that carried crude from inland oilfields to a coastal processing site. The documents were released in the context of ongoing legal proceedings in the UK brought by communities in the Niger Delta.
