5 November 2015, Carbon Brief, Q&A: What does the VW scandal mean for CO2 emissions? The Volkswagen (VW) emissions scandal spilled over into climate policy on Tuesday, after the company admitted to “irregularities” in its CO2 testing results. The firm’s share price — already down 60% after revelations it had deliberately cheated air pollution tests — fell a further 9% by Wednesday morning. However, the irregularities also have implications for CO2 emissions, as well as UK and EU climate targets. Carbon Brief investigates. What are CO2 test “irregularities”? On Tuesday, VW issued a “clarification” about the CO2 emissions testing of up to 800,000 of its vehicles in Europe. The statement says: “During the course of internal investigations irregularities were found when determining type approval CO2 levels…It was established that the CO2 levels and thus the fuel consumption figures for some models were set too low during the CO2 certification process.” Though the precise nature of these problems remains unclear, it has attracted wide media coverage. The Times notes petrol cars have become embroiled in the scandal for the first time. The BBC says the “dirty laundry” is piling up for VW. The Guardian says VW might have manipulated CO2 tests, in addition to its now-notorious “defeat device” for NOx air pollution. The New York Times says VW’s pollution problems have taken a “costly new turn”. A Guardian live-blog says costs for VW could exceed the €2bn it has set aside. Current EU regulations limit car CO2 emissions to no more than 130 grammes of CO2 per kilometre, notes Politico. This is set to fall to a fleet-wide average of 95gCO2/km in 2020. In the UK, vehicle excise duty is linked to CO2 emissions meaning some cars may have had unduly low rates, says Autocar. The Telegraph says some drivers could face higher taxes. However, this year’s budget changed the rules to decouple car tax and CO2 emissions from 2017. Read More here
