World Health Organization Confirms Diesel Fumes as Carcinogenic

UK motorists who are making the swap to LPG powered vehicles had further reason to switch following the announcement on 12 June by the International Agency for Research on Cancer (IARC) - part of the prestigious World Health Organization (WHO) - that diesel-engine exhaust causes cancer. Existing LPG autogas customers have known for some time that LPG autogas is a healthier fuel than either petrol or diesel. But, there is now even more reason to switch to LPG autogas.

Based on recent research, the WHO has decided to name diesel fume a grade-1 cancer-causing substance. It claims that diesel fumes could potentially be as big a public health threat as second-hand smoke, increasing the chances of lung cancer and bladder cancer.

LPG autogas emissions are especially low with respect to noxious pollutants, such as carbon monoxide, nitrous oxides and unburned hydrocarbons, which together contribute to ground-level ozone – a major cause of respiratory illness. And it is not just diesel that causes cancer: gasoline contains benzene and various other unregulated substances that are known to be carcinogenic. On top of that, LPG autogas performs better than petrol and, according to some studies, diesel, with respect to greenhouse-gas emissions when emissions are measured on a full fuel-cycle basis and when the LPG autogas is sourced mainly from natural gas processing plants.

Mike Chapman, Autogas Manager for UKLPG said:

“These reports confirm what we have always said regarding the health advantages of running an LPG autogas vehicle also the savings in fuel costs for the average motorist who converts to LPG have never been higher. “

Added to this, A Which? investigation has found that diesel cars are often more expensive to run than petrol cars. A Which? comparison of diesel and petrol versions of six popular car models has found that petrol engines can often be the more cost effective choice for drivers covering a typical annual mileage. Diesel engines may deliver cheaper fuel bills than their petrol counterparts initially but it takes many years before they actually save the average driver money.

The Which? study also considered reliability, taking information directly from the 2012 Which? Car Survey, which found that petrol cars are generally more reliable than diesels – both in the first three years of their life (the typical warranty period), and even more so between four and eight years-old.
