Are old cars really worse polluters than new ones? | Letters

If so, Ford should prove there's merit to its new scrapping scheme, writes Dr Kevin BannonAs the motor car industry is at the forefront of environmental degradation both globally and locally, it is only right that manufacturers take a lead in tackling the problem (Ford launches ?2,000 scrappage scheme, 22 August). Instead, they offer only a scheme to sell more cars based on an unproven theory. This appears to posit that the pollution created by running an "old" car is so much greater than that of running a "new" one, that an environmental disaster might be delayed if we buy new cars more quickly. If Ford will reveal their figures for this old/new pollution differential and compare them with an evaluation of the pollution created in manufacturing a brand-new vehicle, then we might establish whether or not they know what they are talking about.Dr Kevin BannonLondono Join the debate - email guardian.letters@theguardian.com Continue reading...
