Greenwashed Silvertown tunnel pollutes, trashes the climate, and steamrollers democracy

London’s Labour Mayor, Sadiq Khan, is pushing ahead with the Silvertown tunnel project despite evidence that it will worsen already chronic air pollution problems and undermine chances of meeting climate targets.

Campaigners opposed to the £2 billion-plus project, to build a new tunnel under the Thames between Newham and Greenwich in east London, gathered on Saturday at a Health Summit to hear researchers explain the project’s harmful health effects.

This article is based on a talk at the start of the meeting by SIMON PIRANI, about why, even at this late stage, the project can and should be stopped, and about some of the campaigners’ achievements.

The only arguments in favour of the tunnel are that it will reduce traffic jams at the Blackwall tunnel. These arguments isolate the problem of these jams from all other problems in the world.

Supporters of the tunnel ask us: “What will you do about traffic jams?”

We say: reduce the total number of cars on the road. Which we need to do anyway, to address the appalling levels of air pollution and the danger of global warming.

If you read the London mayor’s transport policy of 2018, it looks as though this is the plan. It has big headlines about non-car transport modes. But the small print, the reality, is very different. The reality is that road transport in private cars is subsidised and supported, and support for other modes is being eaten away.
