Four Ugandan farmers filed a case with London’s High Court on Tuesday, aiming to stop the East African Crude Oil Pipeline (EACOP) from starting to operate by asking the court to apply Uganda’s laws against the project’s UK-registered company.The controversial 1,443-kilometre (897-mile) pipeline, majority-owned by French energy company ​TotalEnergies, aims to carry crude from Ugandan fields for export through neighbouring Tanzania. About 80% has been built so far, according to its developers.The pipeline’s first oil exports are expected as soon as October, according to its developers, and the campaign group Avaaz, which is backing the farmers’ crowdfunded lawsuit, called it "one final chance to stop one of the worst oil pipelines on the planet”.The claim, filed by London law firm Leigh Day, argues that EACOP Ltd's role in developing and operating the pipeline breaches Ugandan laws that protect citizens’ right to a clean and healthy environment.One of the claimants, Racheal Tugume, told a press conference she had been displaced from her land due to the pipeline’s construction, which she said had damaged local rivers, wildlife and ecosystems that communities depend on for their livelihoods just as erratic weather linked to climate change takes an increasing toll.
