The environment is, as ever, dominating the political landscape and Prime Minister Gordon Brown's commitment to the green agenda is firm: 'Just as we manage our financial budgets over the economic cycle with prudence and discipline,' he has stated. 'So we will have to manage our carbon budgets with the same prudence and discipline.' Motorists, in particular, are being called upon to exercise caution and restraint - in other words, to go green.

Low emission, wallet-friendly hybrid cars have grabbed the attention of eco-Hollywood celebrities and now they are in a Lexus showroom near you with the brand leading the solution to companies seeking to reduce their transport carbon footprint.

The hybrid (petrol-electric) RX 400h SUV, GS 450h and LS 600h are in all showrooms giving Lexus more environmentally-friendly hybrid models than any other manufacturer.

Meanwhile, the launch of the first diesel Lexus has seen businesses queuing up to add the IS 220d to their fleet as they help drivers reduce their benefit-in-kind tax bills due to the car's low CO2 emissions.
