ve over, Volkswagen, there's a new diesel stink in town. Focus shifting from diesel car emissions to the generators on construction and demolition sites. Reuters correspondent Barbara Lewis says Volkswagen's help expose a wider scandal.>> Nobody is actually making claims about how clean or dirty These things are but there are an awful lot of them.
And they are running 24 hours a day, adding to air quality which is already killing 9500 people a year in London.>> Emissions Analytics found a small generator emitting roughly six times more nitrogen dioxide than a London bus and 15 times more particulate matter. Nick Molden's firm helped expose the Volkswagen scandal and says it's opened a can of worms.
>> It has served to rip the lid off. All these related issues about engines emitting either more than they should do from a regulated point of view. Or in reality, they emit more than people have ever thought.>> Estimates put the emissions from generators at 12% of all pollution in London, but more research is needed, according to air quality analysts KCL.
>> We have to have a greater understanding of how these machines generate emissions, and how we can prevent those emissions from having a negative health impact.>> While 400,000 early deaths a year are thought to be linked to diesel pollution, the European Union is yet to phase in limits for small generators.
So no one is breaking the law.
