MOTs: Increased Particulate Matter Testing

Jim Shannon Excerpts

Tuesday 24th January 2023 Westminster Hall

[Mr Barry Sheerman (Huddersfield) (Lab/Co-op)]

I beg to move,

That this House has considered increased particulate matter testing during MOTs.

I refer to my declaration in the Register of Members’ Financial Interests. It is a real pleasure to serve under your chairmanship, Mr Hollobone. Air pollution is one of the greatest public health challenges of our time. As we speak, in this place and beyond, people are being poisoned by filthy, unsafe air. Indeed, today the Mayor of London issued a high air pollution alert across the capital.

A diesel particulate filter, or DPF, captures and stores dangerous emissions. It can be found at the back of a diesel exhaust system and can reduce emissions from a vehicle by around 80%. In some instances, a faulty DPF is responsible for the same amount of pollution as a three-lane, 360-mile traffic jam. That is the distance between my constituency of Huddersfield and Land’s End in Cornwall. That truly terrifying fact must spur us on to identify and remove dangerous faulty filters. I emphasise that just one faulty filter in one car can spread that amount of poison.

[Jim Shannon (Strangford) (DUP)]

I thank the hon. Gentleman for giving way. He has been quite insistent and persistent in highlighting this issue. He said that a faulty DPF on a single vehicle can cause the same amount of pollution as a 360-mile traffic jam. Does he agree that while we are putting fresh restrictions on business and manufacturing, there is a simple and effective way of cutting emissions? If so, will he put forward his ideas?

[Mr Sheerman]

I thank the hon. Gentleman for his intervention and he is absolutely right; I will address his point during my remarks.

Increased particulate matter testing during the MOT would ensure that we identified faulty DPFs that are not picked in the current testing regime. I am pleased to see, from the Government’s open consultation on the MOT, which was published last week, that the Government want to adopt particulate number testing.

As chair of the Westminster Commission for Road Air Quality, I have been campaigning on this issue for a long time, and it looks as though we are making some progress at last. If the Government are looking for a legislative vehicle, my Motor Vehicle Tests (Diesel Particulate Filters) Bill is due for Second Reading on 24 March. I am very happy to share it, and all credit for it, with the Minister.

Before I speak more about changes that we can make to the MOT, it is worth dwelling on the life-changing harmful effects of air pollution, which my Bill would help to mitigate. It is estimated that up to 36,000 people die prematurely each year from the effects of air pollution in our country. The total cost to the NHS and social care will be £1.5 billion by 2025 and £5.1 billion by 2035.
