The petroleum industry is described as the 'one of the world's least ethical industries' in a report by the Ethical Consumer Research Association.

In the ECRA report, taking into account corporate responsibility and enviromental impact, they recommend as 'overall best buys' (read 'lesser of the evils');- Murco (Murphy Oil Corp.), Anglo & Repsol (Repsol/Spanish State) and Q8 (Kuwaiti State).

Of course the only real ethical choice is not to use fossil fuel at all. Alternatives to fossil fuels include; electricity (when produced by non-polluting renewable sources), biofuels; Biodiesel, Ethanol (which do pollute), and, perhaps most promising, hydrogen. However the most practical ethical choices to make when considering transport are; walking, cycling or even shared or public transport.
