Volkswagen has softened its stance on tough new European carbon dioxide emissions targets for automakers, betting it can absorb more stringent cuts than its rivals, sources familiar with the matter have said.

The EU last month raised its target for cuts in net greenhouse gas emissions to 55% by 2030 from 1990 levels instead of 40% and Europe's automakers will find out in July what their contribution on carbon dioxide emissions is expected to be.

Three sources said that Volkswagen, which owns car brands including Porsche, Audi, VW, Seat and Skoda, is quietly letting policymakers in Brussels know that it would support more ambitious cuts in emissions than other car manufacturers.
