Local Clean Air Targets

Debate between Charles Walker and Alex Sobel

Tuesday 20th October 2020 Westminster Hall

[Alex Sobel (Leeds North West) (Lab/Co-op)]

Absolutely, Chair—in fact, I am due to speak in the main Chamber very shortly, so I will probably have to leave Westminster Hall straight after my speech.

When the books are written about this period in our history, what will they say? Will they say that 2020 was a time when human beings were confronted with a problem—a pandemic—which, with difficulty, we struggled through and that we then went back to normal? Or will they reflect on a lost opportunity to learn the ultimate lesson—that for all our technical advances and complex social structures, we can still be undone by a single sub-microscopic cell? While we try to put out the fires caused by coronavirus with drastic, difficult and restrictive measures, each one causing damage to businesses and families, we must also keep one eye squarely on the kindling of our next crisis, which is burning, for the moment, away from the media’s attention.

Just as the current public health crisis came with warnings from the scientific community—warnings that were too inconvenient to be properly heard, about a problem whose solutions were too expensive to be funded—our next public health crisis will be no surprise to those who are looking. Our next crisis is an environmental crisis, when the price of Government inaction and lacklustre policy will be paid for by our citizens, particularly the most vulnerable. Words that were not in the common parlance of 2019 are features of 2020: covid-19, coronavirus and the R rate. Without action now, the following words will, in the not-too-distant future, be repeated in living rooms up and down the country: nitrogen dioxide—or NO₂—PM10 and black carbon.

As with coronavirus, we are seeing the impact of our poor air quality right now. The World Health Organisation estimates that 7 million deaths worldwide each year are due to exposure to air pollution—500,000 of them in Europe. Air pollution is outranked as a risk factor only by high blood pressure, high blood sugar and smoking, and it poses particular risks to the unborn, young children, the elderly and those who are vulnerable because of existing underlying medical conditions—we are all now well aware of those conditions. It is estimated that outdoor air pollution contributes to 40,000 premature deaths in the UK each year. Indeed, a report by Public Health England describes poor air quality as

“the largest environmental risk to public health in the UK, as long-term exposure to air pollution can cause chronic conditions such as cardiovascular and respiratory diseases, as well as lung cancer, leading to reduced life expectancy.”

Given those stark facts, the problem can no longer be ignored.

Four and a half years ago, eight cities were mandated to solve a problem. One of those cities was Leeds—my city—and it rose to the challenge. It presented the Government with a plan to tackle our air quality issues. Before discussing that, however, let me first give some background information. Leeds, once known as the motorway city of the ’70s, is the largest city in Europe without a mass transit solution. Research by Public Health England shows that PM2.5 concentrations are estimated to cause over 1,000 adult deaths a year in West Yorkshire, with 350 of them occurring in Leeds. That represents 5.5% of the total mortality in the city, and has been calculated to be the equivalent of 3,825 life years being lost.

Constituents of mine see HGVs hurtle along the congested and over-subscribed A660. I have met people from local primary schools in Pool who describe their fear as these lorries pass through their village, due to its position as a thoroughfare connecting North and West Yorkshire. I walk my own children through streets that regularly miss their air quality targets.

Leeds put forward to the Government its plan for a clean air zone costing £40 million. This ambitious policy proposal, which would have taken high-polluting vehicles off our streets, came into being following hard negotiation, including having to challenge the then Secretary of State for the Environment. However, in January 2019, £29 million of funding was given. The charging clean air zone was meant to have been implemented by now, but last week we had the announcement that it would not be coming forward.

There are some stark warnings here. We have seen our air quality improve, due to new vehicles being brought in by First Bus, by HGV operators and by private hire drivers, but what will now become of those vehicles without the charging clean air zone? There is a real risk that those vehicles will go elsewhere.

What of the legal limits themselves? The UK targets ensure that readings of NO₂ do not exceed 40 micrograms per cubic metre; the target for PM10 is also 40 micrograms per cubic metre, and the target for PM2 is 25 micrograms per cubic metre. However, the World Health Organisation limit for PM10 is 20 micrograms per cubic metre, and its limit for PM2.5 is 10 micrograms per cubic metre. So the Government’s targets on air quality are set at much higher levels than those recommended by the World Health Organisation. The solution to our air quality problem in Leeds and in the rest of the country is to raise the clean air levels and to have a new clean air Act.

There are no safe levels of air pollution; there are no levels that will see mortality levels decrease. If current events have taught us anything, it is that we must prioritise tackling not only the current public health crisis but every public health crisis. If we are not to see the same things continuing to happen in Leeds, Manchester and other places, we need more stringent legal limits. That is what the Minister needs to take back to her Department today and what she needs to implement. Otherwise, we will see this public health crisis also spiral out of control.

[Sir Charles Walker (in the Chair)]

I think we can probably afford colleagues seven minutes, until I let them know otherwise.
