Vehicle Emissions: What are they and how are they measured under the new MOT Test?

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.

Diesel Scrappage: What is it all about?

In recent weeks there has been much talk about diesel emissions and how they are affecting pollution levels around the globe. Diesel engine vehicles are one of the main causes of concern for pollution levels, especially on the back of the Dieselgate scandal, where Volkswagen pleaded guilty in the US to allegations they hid true vehicle emission levels during emissions testing.

Despite the new technology being used in electric and hybrid vehicles, as well as average petrol cars, hundreds of thousands of daily use vehicles are powered by diesel engines, as they are seen to be the most fuel efficient. So, in the face of a potential oncoming vendetta against diesel as a fuel, what can UK motorists do?

Diesel emissions are a real problem when it comes to pollution

 

Government Plans

The British government are currently drafting plans to try and reduce the amount of emissions in cities around the UK. Their ‘Clean Air Plan’ aims to tackle dirty and polluted air, reducing overall pollution. Clean air zones could be set up in dozens of cities and towns, according to the document.

Unsurprisingly, London has the highest levels of air pollution in the UK. According to a 2014 Public Health England report, poor air quality in inner London alone is responsible for 7.2 per cent of deaths in the capital, while previous studies have linked air pollution to 40,000 premature deaths a year in the UK.

The plans to try and reduce emissions have become necessary as the UK has struggled to keep within EU limits on some pollutants, particularly nitrogen dioxide (NO2), which is produced by diesel engines and is linked to a range of respiratory diseases, including asthma. Some 37 of the 43 regions of the UK are in breach of NO2 limits. (BBC)

 

How would the ‘Clean Air Plan’ affect motorists?

The series of documents on a clean air strategy cover a wide variety of options, the most radical measure being considered is what’s termed a “targeted” car scrappage scheme. In its technical documents supporting the plan, modellers estimate that such a scheme could take 15,000 diesel and older petrol cars off the road.

“Under this scheme, 15,000 Euro 1-5 diesel cars/Euro 1-3 petrol cars are replaced with electric cars. The grant level that has been assumed for this option is £8,000,” the documentation states. (BBC)

The suggestion is that a scheme could be brought in within two years.

In a statement, The Department for Environment Food & Rural Affairs (DEFRA) said: “Local authorities are already responsible for improving air quality in their area, but will now be expected to develop new and creative solutions to reduce emissions as quickly as possible, while avoiding undue impact on the motorist.” (Auto Express)

The Clean Air Plan suggests a grant of up to £8,000 for diesel scrappage

 

The UK Government previously introduced a £300million vehicle scrappage scheme in 2009 that applied to all old vehicles. In return for scrapping their old car or van, owners were given £1,000 from the Government towards a new vehicle. However, it seems the incentive to choose a more eco-friendly car will require a larger grant to get motorists to give up their long-serving diesel vehicles.

While there are benefits to embracing a diesel scrappage scheme, it has been reported that motorists could also face a ‘triple whammy’ when it comes to costs, in order to ensure the grants provided to those taking part in the scheme are cost effective. Parking charges, pollution charges, and a new tax increase are all potential dangers for a driver’s wallet.

 

Is my car eligible for the diesel scrappage scheme?

It’s expected that the scrappage scheme will target the oldest diesel vehicles on the road, which also tend to be the dirtiest. Any diesel car or van that’s more than 10 years old is likely to be eligible for the scheme, while more modern diesels will be exempt.

Initially, it’s believed that the scheme will only apply to the 10 most polluted cities in the UK, with London, Birmingham, Manchester and Liverpool all on the list. However, it’s possible that if the initial trial is a success then the scheme could be rolled out nationwide. (Car Keys)

At present, the Clean Air Plan has only been through a first draft, and will likely take some time to be completed. If you’d like to read more about the plan and the results of the consultation that inspired it, you can take a look at the .Gov website here.
