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.
