Any passing Diesel drivers and Enviro babblers might care to reflect upon the true causes of the present disaster and total silence from Labour on the matter. "The records confirm that ministers and civil servants in the Labour government were well aware that diesel pollution damages air quality (even if perhaps they did not appreciate the full extent). But officials preparing the 2000 Budget argued against higher tax for diesel cars "so we are not seen as being overly harsh on diesel users". Advice from the Treasury's tax policy section presented to ministers stated: "Relative to petrol, diesel has lower emissions of CO2 but higher emissions of the particulates and pollutants which damage local air quality. A diesel supplement is necessary so that we do not create incentives for people to choose diesel vehicles over similar petrol models in order to attract a lower VED rate." Reasons for 'dash for diesel' revealed And of course it was really easy to get that: "I first applied for relevant documents from the Treasury in October 2015, under the freedom of information law and the regulations governing environmental information. Their response to the request has involved considerable delays. At one stage the Treasury argued that it would be against the public interest to release any information, as it would damage the policy development process and inhibit the quality of advice. It later changed its stance and said the application would be too expensive to answer. Eventually officials decided to respond partly to a narrower request. Gordon Brown's office declined to comment."
