Letter: Cure for car addicts

Sir: James Cadle's greenhouse effect figures (Letters, 22 November) are misleading: transport accounts in the UK for 22 per cent, and world- wide for 28 per cent, of CO2 emission (OECD, 1993).

Even more serious is the unconscionable waste of fossil fuel. Evidence shows a permanent decline in global oil production within the next 20 years (Nature, Vol 387). Continuing car use increase world-wide will increase the discrepancy between demand and supply, with the certain outcome of wars for oil. One oil war, however disguised, has happened already, in the Gulf in 1991.
