Helping used car buyers go green

Article date: 23 April 2008

Used car buyers can now reduce their carbon footprint with a helping hand from HPI, as it introduces its CO2 Certificate. Free with every HPI Check, the CO2 Certificate highlights the level of CO2 emissions a vehicle creates, using the industry standard CO2 emissions rating chart - similar to those already being displayed on new vehicles. 

"Today, environmental issues are at the forefront of everyone's mind, influencing the food we buy, the holidays we take and the cars we drive," explains Nick Lindsay, director for HPI. "Indeed, transport accounts for one third of UK emissions. For every 6,000 miles the average car travels, it produces its own weight in CO2 emissions and with 30 million cars on UK roads today, this represents a huge carbon burden. Delivered immediately via email once a HPI Check is conducted online, our CO2 Certificates are the ideal tool for those car buyers who would like to compare the emissions of one car with another, helping them reach an informed and greener buying decision."

In a seven band A-G grading*, with category A being the lowest for emitting  levels of CO2 and G being the highest, the certificates enable consumers to consider environmental data when determining a suitable vehicle for their needs. The sheets also offer practical advice to motorists on factors such as the impact driving behaviour has on fuel economy. Car buyers simply conduct a HPI Check online or by phone and will automatically receive the free environmental information sheet.

Nick Lindsay concludes: "Despite a growing number of green concept cars hitting motor shows, none have made great strides into the marketplace. Rather than waiting for a revolution in green motoring, motorists need to look at what they can do now to stem the tide of emissions. With CO2 emissions at the top of everyone's agenda, HPI aims to help used car buyers reduce their carbon foot print and stay on the road to a greener future."

HPI's guide to eco-motoring

  • Consider at the type of fuel you use. Diesel is more energy efficient than petrol.
  • Clear your car of unnecessary clutter - an extra 50lb of weight reduces the fuel economy of your car by up to 1%.
  • Check your tyre pressure is correct to reduce petrol costs by 10%.
  • Avoid jack rabbit starts and over-revving. Wearing soft soled shoes allows you to feel the pedals.
  • Sticking to the speed limit is proven to be good for the environment.
  • Every time you stop then start again in a traffic queue, the engine uses more fuel and therefore produces more CO2. Anticipate the flow of traffic.
  • Idling increases emissions by 13% so avoid doing it - switch off the engine if you can do so safely.
  • Driving in the highest gear appropriate and changing gear early can boost fuel economy by 10%.
  • Use gears wisely to avoid revving which accelerates emissions.


* The CO2 bandings provided are intended as a guide to the emissions of the vehicle and equate to the current Vehicle Excise Duty bandings. Older vehicles may use alternate VED bandings based on emissions or engine size. Visit for the VED banding relating to vehicles manufactured before 2001.
