As of May 20th 2018 the MOT test for vehicles in the UK changed – but what does that mean when it comes to emissions? Never fear, Trust My Garage is here with the answers!
What are emissions?
The Department for Transport (DfT) states that emissions are pollutants created by petrol, diesel and alternatively-fuelled engines. These pollutants are; carbon monoxide, oxides of nitrogen, un-burnt hydrocarbons and particulate matter. The levels of pollutants present in each vehicle can depend on vehicle technology and the state of maintenance of the vehicle – so older cars have a tendency to produce more emissions.
Why do emissions matter?
Like all pollutants, they cause immediate and long-term effects on the environment. Car exhausts emit a wide range of gases and solid matter, which has been cited as a cause of global warming, acid rain, environmental damage and human health damage. Engine noise and fuel spills also cause pollution. Nitrous oxide emissions have also been shown to contribute to the depletion of the Ozone layer around the Earth.
How is the new MOT test combatting emissions?
The MOT test now includes updates for the amount of emissions a diesel vehicle can produce – with garages also having to update their Diesel Smoke Meters to ensure they meet requirements for testing. Find out what the .Gov website states about emissions testing here.
As well as this, if your car is new enough to have a Diesel Particulate Filter (DPF), evidence that it has been tampered with – or the presence of exhaust smoke of any colour – will now constitute a ‘major’ MOT fault. This will need to be rectified before a pass can be issued.
What else is being done to help?
Over time, vehicle manufacturers have realised the importance of emissions and pollution for the environment. The ‘Euro 6’ emission standard has provided a benchmark form of legislation, and as of September 2015 all mass-produced cars sold from this date need to meet the set requirements. The aim of Euro 6 is to reduce levels of harmful car and van exhaust emissions, both in petrol and diesel cars.
Emissions of air quality pollutants from road vehicles have been reduced by improving the quality of fuels and by setting increasingly stringent emission limits for new vehicles. As an example, it would take 50 new cars to produce the same quantity of air quality pollutant emissions per kilometre as a vehicle made in 1970.
How can motorists help?
When you’re driving you may not think about the impact your vehicle could be having on the environment – but if you’re concerned about reducing the effects of pollution, there are some very simple tips to utilise:
Drive Steadily – hard acceleration and braking forces your vehicle to work harder, creating more emissions from your exhaust.
Don’t overload – the additional weight will require you to use extra power. This means that your engine is using more fuel to accommodate the extra kilos.
Have regular services – By keeping your vehicle well maintained you can ensure all its internal parts are working efficiently, putting less stress on your motor and the environment! Don’t forget, you can book a service and find your nearest Trust My Garage member here with our ‘Find a Garage’ map.
Stretch your legs – if you feel comfortable walking or cycling, then do so! Leaving your vehicle at home means it definitely can’t emit any pollutants.
