New cars will have to pass tougher EU examinations to measure their CO2 outputs from today, following the scandal that saw Volkswagen use software to cheat previous emissions tests.

Volkswagen’s new chief executive has told more than 20,000 workers the company will have to review planned investments and contain costs as it works to overcome a scandal over vehicles that cheated on emissions tests.

Irish motorists caught up in the Volkswagen emissions scandal have been advised to compile their fuel receipts and proof of motor tax bills because they could be entitled to damages.
