VW must devise a solution that achieves the NOx standard correctly and minimises CO 2 emissions and clearly show that it works in order to restore trust in the vehicle industry and in government oversight.
Millions of vehicles on roads in the UK and around the world may be operating without properly certified on-road emissions controls, as a result of test manipulation. It is also unclear as to whether the post hoc technical solutions will mean that the emission control systems used to pass the tests will be operationalised for real-world use, at the expense of fuel efficiency and CO 2 emissions, or whether some alternative solution is possible that can achieve both goals.
Although it is accepted that consumers will have purchased these vehicles for differing reasons, fuel efficiency is likely to have been an overriding factor for many. Any solution that results in reducing this aspect is unlikely to be popular and, unless mandatory, will not be taken up by many owners. While emissions reduction may not have been paramount in the minds of all consumers, it is not acceptable that other, potentially more vulnerable, members of the public should continue to be exposed to elevated NOx emissions if the vehicle recall turns out to be optional.
The Real Driving Emissions RDE Euro 6c test, introducing Portable Emissions Measurement Systems PEMS , which is proposed to come into force in , should therefore be a welcome, if belated, change in legislation; however, this is contingent on these new tests being reliable.
A new era of transparency is required. For public trust to be regained the onus is on all motor manufacturers to demonstrate accuracy and compliance, and on governments to ensure rigour, independence and transparency in the process and results.
Competitive advantage and profit margins must not be allowed to take precedence over public health. Diesel light-duty vehicles have received market preference and excise duty incentives due to their fuel efficiency. However, if these results have been influenced by running emission control systems inadequately in real-world use, the viability of the future use of diesel-fuelled vehicles in urban areas needs to be reassessed.
As well as emission tests being required to reflect real-world conditions, diesel vehicles must be required to reflect emission test controls in real-world urban conditions. The message that diesel is environmentally superior to petrol must be expunged from the political, public and commercial consciousness — it is no longer acceptable that there should be a trade-off between public health and climate change and entirely unacceptable that government policy should skew this false choice at the expense of public health.
EPUK therefore calls for a joined-up policy approach across government departments, which clearly recognises and actively communicates the public health AND climate change implications of diesel and petrol to enable consumers to make a rational and informed decision regarding fuel-type and, indeed, mobility choice. This manipulation of the testing regime may seem like just another corporate scandal, but it has caused a substantial amount of illness and death.
As such it has incurred a massive personal cost to the individuals affected, and to the NHS and the economy as a whole. There may be grounds for legal action to recover some of these costs, and to ensure that further deaths can be avoided. Road transport is one of the biggest sources of pollution in the UK, contributing to poor air quality, noise disturbance, congestion and climate change.
Of the 34 million vehicles on our roads, 28 million are cars. Whilst travel by car is often the only practicable option, there are simple steps we can all take to reduce the number of journeys we take and their impact on the environment. The EU has agreements with motor manufacturers that aim to reduce average CO 2 emissions from new cars. Colour-coded labels, similar to those used on washing machines and fridges, are now displayed in car showrooms showing how much CO 2 new models emit per kilometre.
However, as traffic levels are predicted to increase, road transport will continue to be a significant contributor to greenhouse gas emissions. Air pollutants from transport include nitrogen oxides, particles, carbon monoxide and hydrocarbons. All have a damaging impact on the health of people, animals and vegetation locally.
Air quality in the UK is slowly improving, but many areas still fail to meet the health based national air quality objectives and European limit values — particularly for particles and nitrogen dioxide.
In town centres and alongside busy roads, vehicles are responsible for most local pollution. Vehicles tend to emit more pollution during the first few miles of journey when their engines are warming up. Although new technology and cleaner fuel formulations will continue to cut emissions of pollutants, the increasing number of vehicles on the road and miles driven is eroding these benefits. Sources include engine noise, tyre noise, car horns, car stereos, door slamming, and squeaking brakes.
Vehicles have been subject to noise standards for many years through EU legislation. The sound of engines is a problem in towns and cities, while in more rural areas tyre noise on busy roads, which increases with speed, is the main source.
Low-noise road surfaces, effective noise barriers in sensitive locations, and low noise tyres can all help reduce noise levels. Vehicles have a major impact on the environment through their construction, use and eventual disposal. In addition to these emissions of carbon dioxide and other air pollutants, the vehicle and related industries e. Vehicle use affects our whole quality of local life.
Traffic can be dangerous and intimidating, dividing communities and making street life unpleasant. Abandoned vehicles cause nuisance, whilst air pollution and traffic noise can make urban living uncomfortable. This banding is linked to the voluntary colour coded CO 2 A — M labelling scheme. VED discounts are available for alternatively fuelled cars, e.
Air pollutant emissions , such as hydrocarbons, oxides of nitrogen and particulate matter can lead to smog and adverse health impacts such as respiratory illness, cardiovascular disease and cancer. The Euro level listed for each vehicle indicates the air pollution standard that the vehicle meets in Australia. The Australian Design Rules require all vehicles supplied to the Australian market to meet a minimum standard currently Euro 5.
However, many vehicles sold in Australia meet tougher Euro 6 standards adopted in the European Union and other markets. The principal emissions from motor vehicles by volume are greenhouse gases, which contribute to climate change. In vehicles, the principal greenhouse gas is carbon dioxide CO 2 , but vehicles also produce the greenhouse gases nitrous oxide and methane.
Not all vehicles have the same impact though. The vehicle's level of CO 2 emissions is linked to the amount of fuel consumed and the type of fuel used. The road transport sector depends on petroleum based fuels. Releasing some emissions and causing some air pollution is an unavoidable by-product of using a motor vehicle. But there are simple steps you can take to make sure your vehicle's emission levels are as low as possible.

When hydrocarbons and NOx combine in sunlight, they produce ozone. High in the atmosphere, a layer of ozone protects us from the sun's ultraviolet rays.
When holes in the atmosphere's ozone layer allow ozone to come closer to Earth, it contributes to smog and causes respiratory problems. Air pollutants emitted from cars are believed to cause cancer and contribute to such problems as asthma, heart disease, birth defects and eye irritation. Emissions from cars increase the levels of carbon dioxide and other greenhouse gases in the atmosphere. At normal levels, greenhouse gases keep some of the sun's heat in the atmosphere and help warm Earth.
That said, many scientists believe that burning fossil fuels such as gasoline causes greenhouse gas levels to spike, leading to global warming. Scientists use sophisticated instruments to measure concentrations of harmful substances in the air, but it's tough to say exactly what percentage of air pollution comes from cars.
This makes sense, because many other human activities contribute to air pollution as well. In fact, the production of electricity by coal-fired power plants and other sources can cause more pollution than most cars. If that wasn't enough, we pollute the air when we heat our homes and public buildings with fuels other than electricity — just as we do when we drive our cars.
Even people who don't drive add to pollution when they buy goods and services that involve fuel when they're made or delivered. What we do know is that the transportation sector is responsible for over 55 percent of NOx total emissions inventory in the U.
Volatile organic compounds, or VOCs, are gases that are emitted into the air from products or processes, according to the American Lung Asociation , and come from deisel emissions and the burning of gasoline. Although the U. Environmental Protection Agency EPA declared cars " mobile sources" of pollution , they aren't the only culprits.
Big trucks, bulldozers, ships and boats, trains and even snowblowers pollute the air.
