Steele,

"What? Bulldust. Diesel emission standards have nothing to do with the fight against Climate Change but rather they are an effort to tackle the very real issue of diesel pollutants, some of which have been shown to be highly carcinogenic."

Do you really think that diesel emission standards have nothing to do with the push for climate change?

How very naive.

SR you are totally unbelievable. What a convenient memory.

Diesel cars were pushed by some very dumb academics, & climate change gravy train riders, as a way to reduce CO2 emissions from cars. Typically as with all things climate change, these fools are unable to see past their bright ideas to see the actual consequences of those ideas.

Now those climate change fools want to ban the diesel cars they promoted from the city centers where they prefer to live.

Dear Is Mise,

Oh good lord mate, emission standards being discussed here are different to efficiency standards.

A case in point is removing lead from petrol actually dropped the efficiency making it worse for CO2 emissions.

The particulate matter being caught in these filters is highly problematic an is a leading cause of cancer.

"In Australia, diesel engine exhaust is the second most common cancer causing agent (carcinogen) workers are exposed to, behind ultraviolet radiation exposure."

How about you admit you were wrong and be happy that today you at least got to learn something.

AC,

The whole thing about VW emissions was that VW lied about their emission control: it wasn't what their specifications claimed. That, and the cutting out of engines causing at least one death doesn't seem to be related to climate change.

Steele,

"Black carbon, a short-lived climate pollutant, is the second highest contributor to global warming after CO2. Black carbon has a warming effect many times more powerful than carbon dioxide, but it persists in the atmosphere for only a few weeks – so measures to reduce black carbon can also have an immediate effect on slowing the pace of climate change.

Diesel transport is one of the world’s major sources of black carbon (along with household biomass cookstoves). Not only does black carbon have a significant warming effect, but it is also a major component of particulate matter, the air pollutant most closely associated with increased air-pollution related mortality and morbidity."

Frivolous & unnecessary activities by frivolous minded people are the cause of pollution. Nature is the cause of Climate change !
