Natural Environment — House of Lords, 2015-01-15
Topic: Environment
William Bradshaw (Liberal Democrats, Centre to centre-left): My Lords, we were very glad to hear from the noble Lord, Lord Callanan. He brings two things with him. First, he is an engineer. Both Houses of Parliament are woefully short of people with technical knowledge in the various engineering fields. Secondly, he comes from the north-east. One has only to sit and listen to recent introductions to notice how many come from Greater London. This House is very short of people who have a regional perspective on things. To this particular House he brings a third quality: he must feel a lot younger than he did before he came here, being surrounded by so many more mature people I will concentrate my remarks on two or three things. First is the question of emissions. Emissions in town and city centres concern me greatly. A lot of work is being done on the Euro 5 and Euro 6 engines, to which the noble Lord, Lord Callanan, referred. However, a great deal of the pollution in our towns and cities comes from the refrigeration and cooling units on lorries that deliver food and other perishables to shops and airports. These refrigeration engines, which are diesel-powered, do not have the means to send their exhaust through the exhaust cleaning system of the engine. You might clean up the engine that is propelling the lorry, but you have an extremely polluting cooling system attached I am aware from a letter I received from the Minister this morning that there is work going on in Europe on non-road mobile machinery mechanisms, but there is a solution to the problem I have outlined. It is to use compressed air or compressed nitrogen engines to run the cooling units that are so prevalent in the traffic of today. The plethora of delivery vehicles running round from various shops, delivering goods to your home, is all very well but the vehicles bring a lot of pollution with them and this is scarcely recognised. Can the Minister say whether this non-road mobile machinery includes supplementary engines mounted on the road vehicles? I am not sure that it does. The happier news is that there is a technical solution. It is a British solution that has been developed and is going through, I think, the advanced stage of trials. If it is adopted—I am not an engineer and cannot comment on the technology—it will make a huge contribution to cleaning up the air in cities. I know there is debate about the effects of climate change but there is no debate about the health hazards of vehicle emissions The second thing I would like to ask the Minister concerns low emission zones. There are low emission zones in a few places and I have noticed that the Mayor of London intends to make the City—or the whole of London, actually—a low emission zone by 2020. It is important to give people fair warning of these things. Up to a few years ago, they had been encouraged to buy diesel cars. Suddenly to reverse that and say that these cars will now be prohibited is very hard, but if you give notice people can adjust. They sell and buy cars and adjustments can be made, as they have had to be made to buses. I have been involved in the bus industry, as I think is fairly well known I put this point and to some extent I turn to the remarks of the noble Lord, Lord Callanan, about the competitiveness of British industry. There is a lack of inventiveness and a lack of capacity to ensure that good ideas are developed here and exported around the world because they are seen to be necessary and good value. The point about stimulating research, innovation and development here is one that I have heard echoed round this Chamber on many occasions, but it is absolutely important for industries in the area from which the noble Lord, Lord Callanan, comes I will not keep noble Lords any longer but I will be pleased to give the Minister the information I have on air engines, and I would be glad to send it to anybody else who is interested.
