The SMMT (Society for Motor Manufactures and Traders) recently published their first half year figures relating to sustainability indicators. There has been a significant drop in the CO2 emissions figures of new vehicles registered in the last six months, decreasing by 4.5% to 145.2 gCO2/km. This is great news for those of us who want to see a move towards a more sustainable personal transport system. What we must find out now is what the reasons behind this decrease are so that we can ensure that they continue and prosper.
The background environment that motorists have found themselves in over the past few years has undergone some considerable changes. Firstly and perhaps most importantly the worldwide economic recession has put a brake on people’s finances encouraging them to consider large purchasing decisions in greater detail and look to save money wherever possible. The previous trend of the last decade of upsizing vehicles has been somewhat reversed with motorists now thinking about downsizing to enjoy greater levels of fuel efficiency.
New vehicle sales fell off rather dramatically during the start of the recession as households put off large purchases due to the increased uncertainty in the economy. The UK Government introduced a stimulus plan that encouraged households to part ways with old vehicles (over 10 years old since first registration) in exchange for a £2000 reduction in the costs of a new car. This incentive was widely subscribed to generating a substantial decrease in the average emissions level of the UK vehicle car fleet (under the principle that a new car will be significantly more efficient than a 10 year old vehicle). This incentive did not have any vehicle requirements attached allowing households to trade in their old cars for any new vehicle they desired. It was observed that households subscribing to this incentive generally tended to purchase new vehicles that were below the average new vehicle emissions vehicle. This was a unplanned for additional benefit of the UK Car Scrappage Scheme which not only helped prop up the UK’s large automotive manufacturing sector but also moved the new vehicle market in the right direction of lowering CO2 emissions.
