Volvo\'s take on biodiesel
Saw this on volvospy.com...
It was a follow up press release issued by Volvo a few weeks after Volvo completely condemned the use of biodiesel based on that study we discussed here a while back.
The post:
Volvo issued a press release concerning bio-diesel at the beginning of the month (May), suggesting it was 10 times more carcinogenic than low sulphur diesel
Since then, however, a following release has been issued by the company. Reproduced in full:
Volvo Cars is committed to raising awareness and discussion of environmental issues and, for instance, recently sponsored the Green Fleet Conference and Forum in Stratford.
In Volvo's opinion, the perfect fuel for the future is still open to discussion as there are advantages and disadvantages of each alternative.
In its press release of 1 May 2001 Volvo Car UK stated that biodiesel emissions are more carcinogenic than standard low sulphur diesel, based on research carried out at the Chalmers University of Technology in Gothenburg. Although this research contains some interesting results, a recent update from the University states that its study does not allow direct conclusions about corresponding emissions from diesel engines.
However, a broad view of several other studies of biodiesel indicates an increase of nitrous oxide emissions (NOx) compared with diesel. Regarding hydrocarbon emissions (HC), both reduced and increased emissions are reported and further studies are now continuing in all these areas.
Despite biodiesel's biodegradable and renewable benefits, Volvo Cars' experiences indicate some questionable environmental characteristics and, from a user perspective, can have some disadvantages compared to conventional fuels. The potential supply is limited to a few per cent of the current diesel consumption and so could never meet demand.
Where biodiesel is available, Volvo Cars advises a low grade mix (up to five per cent) with diesel. This will give the same carbon dioxide reduction contribution in relation to the amount of fuel available.
