The government body charged with protecting our countryside is helping to kill it by running diesel cars and vans.
Natural England does not have a single pure electric vehicle among its fleet of 106 Toyotas, Land Rovers, Vauxhalls, Fords and Mitsubishis.
Fifteen are hybrids which can run a short distance on electricity.
Diesel has been blamed for an increase in cases of heart disease and premature deaths because of the tiny particles pumped out.
Last night green campaigner Greg Archer, of the Transport and Environment pressure group, said the £153million-a-year quango needed to clean up its act.
He said: “Natural England should be setting an example. Protecting nature and climate are two sides of the same coin.”
Electric vehicle pressure group FairCharge, added: “It smacks of hypocrisy when ministers are encouraging mass adoption of EVs.”
The Government has brought forward a ban on new petrol and diesel cars to 2030.
Natural England, which is headed by £130,000-a-year Marian Spain, says it is “greening its operations”, including intending to replace its vans with electric models next year.
The Department for the Environment said: “Natural England owns vehicles to carry out essential work, including on nature reserves.
"This needs heavy duty vehicles to access more difficult terrain.
"There are at present no suitable electric models on the market for all of this work.”
