My Lords, it is a pleasure to follow the noble Earl, Lord Caithness, and an even greater pleasure to hear a Conservative Peer—a hereditary one at that—speaking so eloquently about climate change, because this is a problem that the UK is not facing up to in a coherent way, so the more that we can do with this Bill, the better. It is not really a surprise that the concept of zero carbon is not in the Bill, because most of it was written before we signed up to that. It was drafted three years ago, and I regret that more redrafting was not done before it came before your Lordships’ House. The Government have had over a year since they put a commitment to net-zero carbon emissions by 2050 into law. I will be very forgiving with the Minister and suggest that they have just not got around to updating this legislation yet.
The amendments in the group, including my Amendment 274, seek to bring the Bill up to date with our net-zero carbon commitment and ensure that agriculture and land management play their proper role in achieving net zero. Agriculture plays a huge role in our carbon footprint and it will grow proportionally as other sources of emissions are reduced. It is therefore essential that the Government should set out a clear trajectory for agricultural emissions and a credible strategy to achieve that. Of course, we have to think about other parts of the economy as well. If we insist on carrying on flying as we did in the past pre coronavirus, other bits of the economy will have to do more to bring our emissions down to zero carbon—so there is that thought as well.
There are some differences between Amendments 272 and 274. Amendment 274 would require net-zero agriculture emissions by 2050, whereas Amendment 272 does not contain this net-zero requirement. Instead, it would require the Secretary of State to have “due regard” to Section 1 of the Climate Change Act. This would mean that agriculture would make some contribution towards the wider goal of net-zero emissions across the economy, but I believe that net zero is possible, and indeed achievable and desirable, for agriculture, and I urge noble Lords to aim to include the amendment in the Bill on Report.
I turn now to the Minister. I have a few things to which I hope that he or she—I cannot see who it is—can give a response. Does the Minister think that net-zero carbon emissions in agriculture is actually achievable by 2050, and what about the important role that setting this out in law will play at stimulating innovation and investment in the right things? Will the Minister undertake to work with noble Lords from across the House to update the Bill by Report stage to reflect the big change in net-zero legislation that occurred last year after the Bill was first drafted? I look forward to the Minister’s response.
