It's admitted now that switching to diesel fuel was a mistake but it was made in the 1990's, 20 years ago. Not as much was known then about Climate Change and it was not as politically significant.
The rise of diesel in Europe the impact on health and pollution
In a bid to reduce CO2 emissions in the 90s, Europe backed a major switch from petrol to diesel cars but the result was a rise in deadly air pollution
The rise of diesel in Europe: the impact on health and pollution
David Fisk, chief scientist and policy director in the department of environment and transport in the 1990s, told the Guardian that there had been “concern” in government when it was proposed that diesel be backed over petrol.
“The motor manufacturers made a démarche to the department of the environment, showing that a major switch to diesels would lead to a substantial drop in CO2 emissions,” Fisk said. He added that the air quality division in the then-Department of the Environment, Transport and the Regions (Detr) saw there was a problem he said – that local air pollution would increase as a result – so a national system of air quality standards was created.
Former
Greenpeace UK chief Stephen Tindale, who was working on air pollution in the department of the environment at the time, remembers a battle between environment and air pollution divisions.
“Air quality was
just not on the political agenda in the late 1990s. In 1997, Labour’s policy was for a 20% cut in CO2 emissions by 2020. Tony Blair wasn’t obsessed with climate but he saw the political and soundbite advantage. The department of health was dozy, with Frank Dobson and then David Blunkett in charge.”
A senior civil servant, now retired, who worked in the department for transport but asked not to be named, said that cost-benefit studies of a switch to diesel were done by government but climate change was “the new kid on the block” and long-term projections of comparative technologies were not perfect.
But the mistake was recognized years ago and the direction was changed. All European countries backed the Paris Accord to reduce emissions. We didn't. Why?
