Air and Water Pollution: Impact — House of Lords, 2017-10-26
Topic: Environment
Susan Miller (Liberal Democrats, Centre to centre-left): My Lords, we know that air and water pollution are killers, but the recently published Lancet commission finding that more than 50,000 UK deaths are attributable to pollution each year—now, in the 21st century—really is a shocking statistic. Of those UK deaths, more than 28,000 are linked to air pollution and over 3,000 to water pollution. As well as the deaths that pollution causes, it drastically affects the quality of life. My noble friend Lady Walmsley will no doubt expand on that Over recent decades, the main reason that successive Governments have cleaned up air and water is that the EU has championed a cleaner environment. The ambient air quality directive sets legally binding limits of major air pollutants that impact public health, such as particulate matter and nitrogen dioxide. Despite this, the UK Government have made little effort in this area so in February 2017, the European Commission gave the UK a final warning over its failure to meet air pollution limits for nitrogen dioxide. Thus, after years of inaction, the Government published their air quality plan but that delay has cost us dearly. My noble friend Lady Jolly will detail the severe costs in terms of health, heart and respiratory diseases and so on that that delay induced The public are paying with their health, with costs to the NHS, yet the UK Government still provide billions of pounds of public funds to subsidise the domestic production and consumption of fossil fuels—some £6 billion per year domestically and some £3.5 billion abroad, according to a report last month from the Overseas Development Institute. By contrast, the Green Alliance has found that due to renewable energy funding cuts, clean energy investment will fall by 95% over the next three years. Greg Clark has launched his green growth strategy to lead the world in fighting climate change, but at the same time the Chancellor has announced a new £5 million fund for oil and gas exploration in the North Sea, hoping to find another 10 billion to 20 billion barrels of oil. That seems pretty contradictory Of course, car manufacturers are well ahead of the Government here. They are well on the way to planning how to phase out fossil fuel-only cars. I think my noble friend Lord Strasburger will be talking about that. I am sure he shares my frustration that the Government have passed so much of the responsibility for cleaning up city air to local authorities, without introducing in parallel a high-polluting vehicle scrappage scheme, which many city leaders have requested. I know my noble friend Lady Randerson will outline the challenges and explain what a Liberal Democrat green transport scheme would contain The health impacts of water pollution will prove to be much more serious than we realise. One threat is from relatively new compounds. An example is microplastic contamination, which has been found in 72% of tap water samples in Europe. I commend the Government on starting to address this matter, because it is very urgent. They intend to ban cosmetic microplastics. The Microbeads Coalition, which includes Greenpeace, has said: "The ban announced by the UK government is world-leading in its ambition to successfully put a stop to this source of marine pollution" But I must say, shame on the cosmetics industry for lobbying against the ban in Brussels. I must also commend the Government on the UK signing up to the UN Environment clean seas campaign and making various voluntary commitments on marine protected areas, including in our overseas territories Another threat from new materials is well outlined in the Parliamentary Office of Science and Technology’s POSTnote on nanomaterials: "Engineered nanomaterials may end up in lakes, rivers, oceans, aquatic sediments and soils. When nanomaterials enter water, they tend to aggregate together ... So far, most studies into the effects … on aquatic life ... suggest that nanomaterials can reduce growth, reproduction, locomotion, breathing and feeding" That is pretty much life itself. There is a caveat: that the studies so far, "used higher concentrations of nanomaterials than current predicted exposure levels", but nanomaterials are a very real danger. Will the Minister tell the House what further research into this the Government are intending to do? Nanomaterials accumulate at the bottom of the food chain and food crops can absorb them, so there are a number of threats I now turn to the main causes of water pollution besides new materials and how we can tackle them. The first is sewage. There are still 31,000 combined sewer overflows in the UK. As soon as there is heavy rain, these sewers discharge untreated human sewage into our rivers. Failure to implement much-needed sustainable urban drainage systems has cost us and our environment dearly. A question really sticks in my mind: what do you get if you mix a gallon of sewage with a gallon of storm water? The answer is two gallons of sewage—it is fairly obvious. The question comes from the city manager of Philadelphia in the US, which has become a model of how to build green infrastructure to deal with the issue. It had old Victorian sewers too, but in 2000 it began to plan 19 square miles of green infrastructure to cope with 9 billion gallons of sewage: rain gardens, porous pavements, lots of trees, and green roofs in public and private spaces. Everyone is signing up to it. We had a presentation on that in this House, so there was a chance for the Government at that time to take up the idea, but instead they did nothing. London faced a similar issue. Storm water was washing into the Thames. It is only as a result of my noble friend Lady Ludford’s petition that proceedings have resulted in the 25 km storm tunnel which will start to deal with this issue. Our cities need to take a leaf out of Philadelphia’s book The second source of pollution in water is agricultural. Many products are used on farmland for good reason, for example nitrogen and phosphates, but become pollutants once they wash into water. Besides encouraging minimal input use—precision farming, organic farming and so on—what else could be done? South West Water has taken a positive approach and found that reducing pollution at source, rather than treating water downstream, has a truly surprising benefit-cost ratio of 65:1. Its upstream thinking programme supports farmers who are upstream of key water supplies with grants and advice, so that they can manage their business with clean water and a healthy natural environment in mind Clearly, any future farming support must be linked to a clean record, but Brexit poses a risk of actually increasing agricultural water pollution. Why? Removing slurry costs farmers about £12.50 a tonne, and if all of a sudden common agricultural policy subsidies go, farmers will be unable to afford clean-up schemes while transitioning to a more positive way of dealing with this, such as the example I have just cited. There is also a danger that any pollution may go unchecked post Brexit if the Government continue to view reporting requirements as an example of technical requirements that they want to get rid of. The impact assessment lists reducing reporting requirements as a potential cost saving. That is totally wrong. British citizens have every right to know whether the state of their environment is a source of danger to their health. I urge the Government to maintain the reporting requirements and the bodies necessary to do that What do we need from the Government in the short term to tackle some of these issues? Next year’s review of the national planning policy framework would be a good start. The Government could choose to introduce effective planning requirements for sustainable drainage systems that tackle the sewage situation. I am sure the Minister appreciates that a new agricultural policy whereby land is a crucial part of a newly recognised green infrastructure would be a major part of addressing this need to clean up our water. A commitment must be made to match spending on farm support, while ensuring that the public goods element of any support expands, and the idea that you just bring in some land and get support for it is a thing of the past. Unfortunately, water legislation has been knocked on to the back burner by Brexit. We should by now have had a review of the licensing system for water abstraction and permitting for sewage overflows, but they have both been heavily delayed by Brexit. Brexit leaves little time and no political space to tackle these basic, crucial issues of everyday life I end with a plea. If Brexit does happen, we will seek to ensure that the Government continue with environmental reporting requirements, with no cancellation of reporting as a "technical requirement" or seeing it as a cost-saving measure. We will need measures in place to ensure that we continue actually to clean up our air and water. I beg to move.
