A report shows what contempt they have for pollution controls. Apparently they have done virtually nothing to reduce pollution, with some still emitting as much particulate matter as 1m cars a day. The annual survey of 63 ships, conducted by the German environment group Nabu, refused to recommend a single one for adequately reducing its environmental impact in 2017. It accused the industry of having “contempt” for the health of its customers, saying companies had reneged on promises to clean up their fleets. “Last year the sector claimed 23 ships would be operating with soot filters,” said Nabu’s Dietmar Oeliger. “The truth is not a single filter is working at present.”
