Air and Water Pollution: Impact

Earl of Caithness Excerpts

Thursday 26th October 2017 Lords Chamber

[The Earl of Caithness (Con)]

My Lords, I am grateful, as we all are, to the noble Baroness for securing this debate. It is the second time that we have discussed air pollution in a few months; the last debate, on 3 July, was introduced by my noble friend Lord Borwick, who I am glad to see in his place. I am particularly grateful that the noble Baroness included water in this debate, which is important. However, I would say to her that I was sad she was a little negative. There are plenty of positives to be taken from what has happened, which I shall mention.

To me, pollution is anything that is toxic, harmful or a nuisance. As a result, pollution is not a simple problem, but a number of different ones. It is an international, a national and a local issue, and not a simple problem to address. It is hard to tackle because its effects, which may be long-term and subtle, are often difficult to trace to a particular cause and that makes coming up with a solution very difficult. We cannot eradicate pollution. Even if we can trace the cause, a solution might be hard because it might have been caused by human error, thoughtlessness or incompetence. Our constant challenge therefore is to mitigate the chances of pollution happening. Air and water are essential for life but, as the noble Baroness rightly said, pollution can kill.

Most of the damaging effects of air pollution occur across the life cycle and can begin at conception. The effect can range from premature birth to declining lung function, especially in later life. In the UK, air pollution costs businesses and healthcare services over £20 billion annually and is estimated to result in about 40,000 premature deaths—what a waste. In addition, air pollution causes a reduction in agricultural yields, irreversible damage to ecosystems and biodiversity, as well as damage to historical buildings and monuments—just look at this place. The effect of pollution on plants and ecosystems has been well noted for many years and I am reminded of what the great Scottish gardener WW Pettigrew, who did so much to create the beautiful parks in Cardiff before he moved to Manchester, wrote about pollution in 1928—some 90 years ago. I therefore support what the Minister said when he wound up the debate in July. He said: “The need to improve” our,

“air quality is of paramount importance”.—[Official Report, 3/7/17; col. 774.]

I hope he will give water the same high priority.

Despite the current problems, substantial improvement in air quality has been delivered. UK emissions of nitrogen oxides fell by 70% between 1970 and 2015 and almost 20% between 2010 and 2015. In February this year the UK was compliant with all current EU and international emission reduction targets, which have been applied since 2010. I take the completely contrary view to the noble Baroness: the EU has let us down, particularly on emission standards. EU businesses, German car-makers and the Commission have been very poor and have not helped anybody on the European continent. New targets have been signed up to and I have little doubt that, whichever Government are in power, every effort will be made to meet them. These new standards will affect business decisions vital for this country’s growth, such as the new runway in the south-east. But it is right that such issues of natural capital are included in the planning stage.

Even if we had no air pollution from within the UK we would still have air pollution because, at times, over half our air pollution comes from abroad, bringing with it in many cases diseases which are damaging both to us and to the environment. Whether we are in or out of the EU, we will have to work with international partners to improve not only their standards but also the measuring of those standards, and the uncensored publication of the true situation.

Being an island does not isolate us from incoming air pollution, but it helps us hugely with water. Our rivers are our own and do not contain another country’s pollution. As with air, water quality is a success story. In the early 1990s just 28% of bathing waters in England met the highest standards. Now it is 93.2%, with even tougher standards being implemented. In 2016, compliance with the EU drinking water directive was 99.96%. The public supply in England provided for a population of over 54.5 million people and came through 313,000 kilometres of mains pipes. Water companies carried out nearly 4 million tests of which only 1,132 failed to meet the necessary standards—that is impressive. We are truly spoilt in this country and take what we have very much for granted.

It is easy to think of polluters as industry and businesses. Those are the easy targets. It is much more difficult for us to acknowledge our contribution as individuals. I mentioned gas boilers in our previous debate, but a recent study in America shows that gas ovens are increasing internal NOx and carbon emission pollution by anything between 20% and 40%. This is mostly due to bad ventilation. When it comes to water, we as individuals pollute through such items as sewage, wastewater, soaps, washing detergents, oil poured down the drain, high rain street run-off, particularly from our cars, and litter. There is to be a 25-year plan, and that needs to involve individuals and resonate with them, because it is often the poorest and most vulnerable who are affected by pollution although, as I said, they also contribute to the problem.

Post Brexit, we have a huge opportunity to improve our position. I suggest to the Minister that it is the Government, their agencies and local authorities which should continue to set the standards, but let us go back to something like Her Majesty’s Inspectorate of Pollution—not subject to ministerial control, as it was in my day, but totally independent, so that the Government set the standards and we take away from their agencies the enforcement thereof. Let us have an independent inspectorate.
