Oils from any source still produce CO2. Greenhouse gas.


I'm surprised by that statement Mary. Surely the point is whether a fuel
is carbon-neutral or not. If you burn veg oil in your boiler, your net
CO2 contribution is almost zero (processing/transport costs mean it
isn't *zero*). This is a far 'greener' way of heating your house than
using electricity derived from any source other than nuclear.

By the way - global warming - despite what the media would have you
believe, scientific opinion is still very much divided over whether
*any* of the observed global warming is anthropogenic in nature.
