Environment Bill

Viscount Ridley Excerpts

Committee stage
Wednesday 14th July 2021 Lords Chamber

[Viscount Ridley (Con) [V]]

My Lords, it is a pleasure to follow my noble friend Lady Noakes, whose expertise on these matters is extraordinary, and to support the very important amendment of my noble friend Lady Neville-Rolfe. This is only the second time I have spoken in Committee, and I will try and keep it brief because I know we are at the end of eight long days.

At Second Reading, I paid particular attention to the issue that some environmental policies do not end up being effective—do not work. Others are worse; they actually produce counterproductive results in environmental and economic terms. This amendment is a way of making sure that this does not happen—at least, not for a long time—that we learn from mistakes, that we put things right and, as my noble friend Lady Neville-Rolfe put it, that we have a fail-safe.

I would like to give four short examples of policies that were brought in to help the environment and ended up hurting it in significant and expensive ways. The first was the policy of encouraging us all to buy diesel cars as opposed to petrol cars 20 or so years ago. There is no doubt, if you go back and look at the debates at the time, that this was pushed as an environmental measure, because diesel cars had lower carbon dioxide emissions per mile. It was pushed strongly by big German car manufacturers as a way of encouraging Governments to think they could get a quick win on the environment. Of course, the effect it had was to increase emissions of nitrogen oxides and particulates, which are much more harmful to human health, as well as to the environment.

The second example is the diversion into compact fluorescent light bulbs. Around 10 years ago, incandescent bulbs were banned, and we were all forced to buy compact fluorescent bulbs. This was pushed strongly as an environmental measure by the large manufacturers of compact fluorescent bulbs because they used less electricity to produce a given amount of light. But they were very unsatisfactory in all sorts of ways, including that they did not switch on very fast, gave a pallid light, were very expensive and were toxic for the environment if they broke. Along came a better technology, the LED bulb, which we have all willingly gone out and bought to replace them. It is even more efficient in terms of the environment, even more energy efficient; it is expensive, but not as expensive as compact fluorescent bulbs; and it has easily replaced both the preceding technologies. My point here is that we did not need the diversion into compact fluorescent bulbs. It probably delayed the arrival of LED bulbs. The evidence on that is quite good.

My third example is the fact that we are burning trees in Yorkshire in Drax power station to keep the lights on in Britain. The trees mostly come from North America; we are stealing the lunch of woodpeckers, beetles and other organisms to have electricity in this country. We are subsidising this. We are calling it renewable, because the trees regrow. But they regrow over decades and, even then, if we are continuing with this, we will presumably cut them down again. Doing this does not make any sense, because burning trees produces more carbon dioxide than coal in the production of electricity. About 7% of our electricity came from biomass burning this morning.

My fourth example is one I referred to in my Second Reading speech and is that some environmental policies have encouraged farmers to make peewit-friendly habitat, where lapwings will come and breed. That sounds good from an environmental point of view, but it has recently become clear that if you do that, but do not control crows, foxes and stoats in the area, you will draw in lapwings to what looks like an attractive place to breed, but they will never see any grandchildren, because the success rate of lapwings in these areas is about 0.1 chicks per pair, which is not sustainable. So you are draining the population of lapwings if you do only one part of the policy and not the other.

A similar point was made in an excellent speech by the noble Earl, Lord Devon, who talked about the problem of making conservation covenants in perpetuity, then struggling with what to do when we find that we have made a mistake in a conservation covenant and have put in place a policy for a piece of land that is inappropriate and doing more harm than good. That is why it is vital that we apply sunset clauses and cost-benefit analysis to environmental policies. We need a chance to pause and say, “Sorry, chaps. I know you are making a ton of money out of this policy, but it is not helping the environment, so we are going to shunt your gravy train into a siding, because it has failed a cost-benefit analysis”. That is what we should be in the business of doing.

Those who support greater action on the environment ought to be especially welcoming of this amendment, because it is all about finding out what works, what delivers good value for money and what should be ditched because it does not work. If the Minister does not like this amendment, I would be grateful if he could set out how he plans to deal with it the next time we find that an environmental policy foisted on us by lobbyists turns out to be counterproductive for the environment.

[Viscount Trenchard (Con)]

My Lords, it is a great pleasure to follow my noble friend Lord Ridley, who gave a fascinating speech. I was much impressed by his four examples of policies that we thought were going to be very good but turned out to be mistakes and had to be changed. I am sure the same will happen with some of the current policies being proposed for the environment and other things that we think, today, are bound to give the right answer when, in 10 or 20 years, some are certain to be counterproductive.

I will not detain the Committee long, but I extend my support to the sensible Amendment 297A in the names of my noble friends Lady Neville-Rolfe, Lord Ridley and Lady Noakes. The Bill takes no account of any negative impacts that the environmental targets set may inadvertently cause. As your Lordships are aware, we do not always get everything right. We should pay attention to the proportionality principle, as sensibly proposed by the Taskforce on Innovation, Growth and Regulatory Reform, chaired by my right honourable friend Iain Duncan Smith.

My noble friend Lady Neville-Rolfe is the strongest advocate of impact assessments in your Lordships’ House. As was also pointed out by the noble Lord, Lord Vaux of Harrowden, planting trees in areas that were not historically forests may assist climate change mitigation, but may also harm biodiversity. Similarly, some actions taken to advance environmental targets may have a negative impact on carbon emissions, such as the plastics tax, which is likely to cause a shift from plastic to glass and aluminium bottles—about which I spoke in an earlier debate. For these and other reasons so well explained by my noble friends, I hope the Minister agrees that it is right to include a sunset clause and that the Government should conduct a cost-benefit analysis if they wish to renew these regulations beyond five years after the passage of the Bill.

On the interesting subject raised by the noble Lord, Lord Berkeley, whose support on other aspects of the Bill I much appreciate, I am conscious of my oath of allegiance to Her Majesty the Queen and of everything His Royal Highness the Duke of Cornwall does for the environment. I would prefer to remain silent on this matter, but I look forward to hearing how the Crown replies to the noble Lord through my noble friend the Minister.
