NONE of Britain's biggest companies has a truly green transport policy, according to an Environmental Transport Association survey. Early last year the ETA sent questionnaires to the top 100 FTSE companies in a bid to gauge the corporate environmental transport responsibility of each. Of the 54 who responded, none scored top marks.

Andrew Davis, director of the ETA, said: 'The results indicate there is still much to be done by Britain's top companies if they are to convince us of their commitment to the environment. However, of those who did respond, most had board level commitment to the environment.'

The Trust plans to repeat the exercise later this year. Among the questions FTSE 100 companies will be asked are: Does the company have a cash for car scheme? Does the company encourage car pooling in company vehicles? Has the company taken into account the influence of free fuel on levels of personal mileage? Does the company encourage long journeys to be made by rail combined with local transport? Does the company provide cycle parking, loans for cycle purchase and cycle mileage allowances?

When the results were published in September, 1997, Safeway, Marks & Spencer and Unilever were among 15 deemed companies with the greenest transport policies, Argos, Railtrack and SmithKline Beecham were middle ranking with 17 others, while EMI, Imperial Tobacco and Thames Water found their way on to the 19-strong 'least green transport' list.
