This is but one example of governments around the world moving to offer tax breaks and subsidies to promote the far more carbon-neutral biofuels of ethanol and biodiesel. Under the United Kingdom's Renewable Transport Fuels Obligation, five percent of transport fuel sold by 2010 must come from renewable sources. This relatively small percentage is expected to cut carbon emissions by an amazing 1m tonnes, equivalent to taking 1m cars off the road.
Businesses are getting behind emissions reductions schemes as well, for example, the giant Tesco supermarket chain is currently trailing a system developed by Clean Air Power, which enables its truck fleet to run on a mixture of natural gas and diesel. Not only does this allow Tesco to meet local emissions regulations, but they will save considerably on their fuel bill as well. The chance to improve the bottom line will always get a company's attention, but often its individual employees that bring such opportunities into focus for business. If you're working for a company, make sure you take a look around for a chance to save them money, and your environment as well.
