Fuel for thought
Tuesday, January 27th, 2009It hopefully hasn’t gone unnoticed that Addison Lee’s efforts to reduce the negative effect of our business on the environment has been fairly relentless. In addition to the recognition we have received in the shape of prestigious awards from the Energy Savings Trust and the accolades bestowed upon us by the London Green 500, there are constant behind the scenes efforts made by our Corporate Social Responsibility team. The environmental issue is clearly not going to go away in a hurry. Companies such as Addison Lee have a definite obligation to source the ‘greenest’ methods of transport and fuel, which leads nicely on to one of the most contentious subjects of all - hybrid vehicles.
The private hire industry has undoubtedly seen an upsurge of smaller firms adding hybrid vehicles to their fleet, with some companies opting only to have non-diesel cars. The concept appears to be very noble, but what it is not often reported is the methodology involved in creating these battery operated ‘runarounds.’
It is a popular misconception that the Toyota Prius is the greenest vehicle on the road. In fact, nothing could be further from the truth.
The Prius is powered by not one, but two engines: a standard 76 horsepower, 1.5-litre gas engine found in most cars today and an additional battery powered engine that deals out 67 horsepower and 295ft/lbs of torque below 2000 revolutions per minute. Essentially, the Toyota Synergy Drive System, as it is so called, propels the car from a dead stop to up to 30mph. This is where the largest percent of gas is consumed. The battery is recharged through the braking system and when the gasoline engine takes over anywhere above 30mph.
Building a Toyota Prius causes considerably more environmental damage than a standard diesel car. As previously mentioned, the Prius is partly driven by a battery, which contains nickel. The nickel is mined and smelted at a plant in Sudbury, Ontario. The plant produces 1,000 tons of nickel annually and has caused so much environmental damage to the surrounding landscape that NASA has used the ‘dead zone’ around the plant to test moon rovers. The surrounding area is devoid of any life for miles.
It was reported by the Canadian Greenpeace energy coordinator, David Martin, that the acid rain around Sudbury was so severe that all plant life was destroyed and the soil slid off the hillside.
However, the environmental damage does not stop at the plant. The nickel is subsequently transported via massive container ships to the largest nickel refinery in Europe. From there, the nickel is flown to China to produce ‘nickel foam.’ From China, it is then sent to Japan and finally, the completed batteries are shipped to the country of sale, completing a multi-continent journey required to produce a single Prius battery.
Addison Lee has given considerable thought to adding hybrid vehicles into our fleet. As London’s largest minicab company and with a proud history of reinvesting profits into innovation and technological advancements, if we considered it to be both environmentally friendly and better for our clients, we wouldn’t hesitate to do so. However, it is our absolute belief that this simply isn’t the case.
