Some alternative vehicle fuels such as liquid coal can cause more harmful greenhouse gas emissions than petrol or diesel, scientists warn. "Liquid coal, for example, can produce 80% more global warming pollution than [petrol]," says the US non-profit environmental group, the Union of Concerned Scientists. Some people have billed liquid coal, the name for petrol or diesel derived from coal, as a potential replacement to the oil on which countries rely heavily to fuel vehicles.

Likewise another alternative fuel, petrol from tar sands, is estimated to have 14% more global warming potential compared with standard petrol, says the union in its latest report Biofuels: an important part of a low-carbon diet.
