I beg to move,

That leave be given to bring in a Bill to set standards as to the emissions particulate sensing technology to be used in roadworthiness tests for diesel vehicles; and for connected purposes.

As you know, Mr Speaker, I have been a Member for a very long time, but it is 20 years since I last moved a ten-minute rule motion, so I hope everyone will be tolerant of me today.

I declare my interest as chair of the Westminster Commission for Road Air Quality, as an active member of the all-party parliamentary group on air pollution and as chair of the World Health Organisation’s global network for road safety legislators.

Throughout my career in this House, as many colleagues may know, I have been a passionate campaigner for the environment, and I know that colleagues on both sides of the House share the view that we and all our constituents have an inalienable right to breathe clean air. It is now clear that toxic air is one of the greatest public health challenges of our time, affecting pregnant women, the elderly and our children and grandchildren. No one is exempt from breathing poisonous, polluted air in our country.

As a former Chair of the Select Committee on Education, and in much of my other work, I have always believed in pursuing good, evidence-based policies. On air pollution, the experts and the science are crystal clear. The challenge cannot be overestimated and it urgently requires not just a joined-up approach, or just a cross-party and cross-sector partnership, but a recognition of the huge scale of the challenge we face.

The Government are fully aware, because they have the records, that up to 36,000 people a year are dying from breathing polluted air. Indeed, it was linked to over 150 deaths in my Huddersfield constituency in 2020. Not only is it a tragic loss of life to this invisible killer but there is a huge economic cost, estimated at £20 billion annually, from the accumulation of treating health conditions and days missed at work.

This is a challenge that we are morally obliged to solve, but reducing air pollution is also vital to our economy, to our health and to the general wellbeing of our society. I am particularly proud to have worked over the past few years with Professor Sir Stephen Holgate, one of our greatest experts on this issue.

It is estimated that just short of 30% of our noxious emissions come from the transport sector, and over 90% of these emissions come from road transport vehicles—the cars, vans and lorries we see every day. Many of the challenges we face on air pollution will take major research, innovation and intervention, which will take considerable time and resources, but we also have an opportunity to seek more rapid, achievable wins. This Bill is at the top of the list.

Tackling diesel emissions can be achieved relatively speedily and, if this House so chooses, the Bill would have a profound impact on air quality in our towns, cities and communities in the short term. The World Health Organisation has made it crystal clear that diesel emissions have a dangerous impact on human health, especially respiratory health.

My hon. Friend the Member for Lewisham East (Janet Daby) is familiar with the scale of the challenge, given the tragic case of Ella Kissi-Debrah. Ella’s death and the evidence linked to her case shows just how devastating toxic air can be in urban spaces. Her mother, Rosamund, continues to campaign passionately for change to the law, and we must not let her efforts be in vain.

This brings me to the core purpose of my Bill. All diesel vehicles need to be fitted with fully functioning and fully operational diesel particulate filters—DPFs. A DPF captures and stores dangerous emissions released by the vehicle. If DPFs are not working and are not checked properly, that is how we get the pollution. Independent research shows that a single faulty filter produces the same amount of pollution as a three-lane, 360-mile-long traffic jam with vehicles that have proper, functioning DPFs fitted. That is the distance between my constituency of Huddersfield and Land’s End.

To be fair, as a country, we have made some moves in the right direction. In 2014 and 2018, MOT tests became marginally more rigorous to ensure the proper working of these filters. But now, in 2022, we are being left behind and our MOT tests in this area are once again insufficient and out-of-date. Governments in countries such as the Netherlands, Belgium and Germany are making faster progress in reducing the levels of ultrafine particulate matter through simple improvements in MOT testing. This is of particular concern to me because one of the things that this does is to accelerate the ageing process. Looking around the Chamber, that concerns some of us very much indeed. In the Netherlands, 10 improved models of devices that test the efficiency of these filters are already set to be approved by this July. The Dutch, using more sensitive technology, are picking up on the real efficiency of these filters. The revised test would require improved sensing technology set at 250,000 particles per cubic centimetre. The current testing system in the UK picks up only 1% of faulty filters. With the higher standard used in the Netherlands, it is estimated that 15% more filters would be identified as faulty.

Checks on diesel particulate filters do make up part of the current requirements for diesel vehicles, but at present the test seeks only to determine if these filters are obviously defective or actually missing. I have been in touch with the Secretary of State for Transport and his ministerial team about this issue on several occasions and have always been told, “We already have safeguards in operation.” However, the fact is that thousands of vehicles are falling through the cracks of this out-of-date testing system, to the serious detriment of air quality and public health nationwide. So, in essence, my Bill would bring the UK up to the highest possible standards in MOTs. It would introduce new sensing technology that would identify less obviously defective but still dangerous filters. It would ensure that vehicles are roadworthy and fit for Britain’s roads. Finally, these more stringent tests would protect the health and wellbeing of millions of drivers, passengers and pedestrians throughout our country.

This Bill is entirely realistic in its ambitions. Its proposal is tried, tested and has been rolled out repeatedly in other countries. It is a small change to make but it would potentially have huge, life-saving impacts. Other countries’ experience has shown the best practice that we can achieve. It is now clear that all we must do is to follow these examples and build consensus across this House and across industry to get these emissions down. In my experience, so many of our constituents want to play a role in addressing the climate change crisis. They may not be Greta Thunberg, David Attenborough or Bill Gates, but they want to help to make a difference in their communities and in our constituencies.

I believe that responsible citizens would readily change their behaviour and support these efforts if they were made aware that their vehicle had a broken filter and was poisoning the air we all breathe. Last week, I presented a Bill to the House that would put a duty on every local authority to audit the quality of its air and annually report this to Parliament. With the support of this House, MOT providers, road users and pedestrians would be able to proceed in the confidence that these changes can be brought into effect without unsustainable costs for garages or for drivers.

What is clear is that we cannot afford to wait. We are making advances in technologies such as hydrotreated vegetable oil fuel—with the help of Lord Tebbit’s son, William Tebbit—and hydrogen and battery technologies are moving forward, but not fast enough. The UK should not be a follower in making MOT tests more rigorous; it should be a leader. We continue to hold the presidency of COP26 and there is still a window to show decisive, bold and thoughtful leadership. Let us take this step together and move closer towards achieving a goal that we should all share across this House: that our children, grandchildren, friends, family and loved ones are united in the right to breathe clean air.

Question put and agreed to.

Ordered,

That Mr Barry Sheerman, Clive Efford, Christine Jardine, Geraint Davies, Kim Leadbeater, Dr Philippa Whitford, Huw Merriman and Sir Robert Goodwill, present the Bill.

Mr Barry Sheerman accordingly presented the Bill.

Bill read the first time; to be read a Second time on Friday 18 March, and to be printed (Bill 252).

Mr Deputy Speaker (Mr Nigel Evans)

Barry taught me politics at Swansea University, so it is wonderful to be here for his ten-minute rule Bill.
