The UK, France and Germany have been accused of hypocrisy for lobbying behind the scenes to keep outmoded car tests for carbon emissions, but later publicly calling for a European investigation into Volkswagen’s rigging of car air pollution tests.
 
 Leaked documents seen by the Guardian show the three countries lobbied the European commission to keep loopholes in car tests that would increase real world carbon dioxide emissions by 14% above those claimed.
 
 Just four months before the VW emissions scandal broke, the EU’s three biggest nations mounted a push to carry over loopholes from a test devised in 1970 – known as the NEDC – to the World Light Vehicles Test Procedure (WLTP), which is due to replace it in 2017.
