Part of the debate – in the House of Lords at 9:15 pm on 24 July 2023.
My Lords, I welcome the noble Earl, Lord Russell, to his place, It was an excellent maiden speech and I look forward to working with him in the coming years. I also congratulate the noble Lord, Lord Krebs, on securing such a timely debate.
As we convene this evening, fires rage across Europe. Families have had to be evacuated from Rhodes and now Corfu, and temperatures have broken all records. Parts of southern Europe exceeded 47 degrees yesterday. People are struggling, roads are melting and crops are failing in the extreme temperatures. Unfortunately, this is not a unique phenomenon. Last year, 61,752 people died across Europe due to excess temperatures.
Earlier this month, your Lordships’ House questioned the Government on potential global temperature rises of 4% by 2100. While I pray that our planet will not experience such an increase, it is no longer beyond the realms of possibility. However, it is nearly recess, and I wish to be slightly more hopeful. No one who has listened to the calibre of this evening’s debate should question our collective desire to achieve net zero and try to mitigate the worst excesses of the damage already done. This debate has also demonstrated the sheer scale of the issues in front of us, as each noble Lord has highlighted a different threat posed.
Climate change is no longer an academic theory: we are living through the realities every day, and the impact of our changing environment is beginning to affect every part of our lives. It is crucial that we not only seek to mitigate the damage we have done to our environment but prepare effectively to manage the impact of changing temperatures on our daily lives.
As we have heard throughout the debate, the impact of climate change is indiscriminate. Let me touch on some of our deepest concerns. As the NFU has stated, last year was the driest on record in the UK since 1911. This has had an impact on both our domestic agri-businesses and our long-term water table and biodiversity, which in turn will have an impact on the security of our food supply.
Rising temperatures and the increased frequency of extreme weather events are contributing to crop damage and loss, with potentially dramatic consequences for both domestic and global food security. The Government have put many of their eggs in the basket of gene-edited climate-resistant crops, having passed enabling legislation for the development and marketing of such products earlier this year. Can the Minister provide an update on this work and the ongoing discussions being held with stakeholders?
On a similar theme, earlier this year we saw disruption to supply chains as a result of extreme weather conditions in north Africa and across the Mediterranean. Supermarkets called for government support, but Ministers resisted on the basis that supply-chain issues should be resolved by business, not the state. Can the Minister assist the House by letting us know what steps the Government have taken to track progress made by retailers in relation to supply-chain diversity and appropriate mitigations? Do the Government expect the introduction of import checks later this year to exacerbate shortages when they arise?
Moving to a different aspect of security just touched on, I declare my interest as an honorary captain in the Royal Navy. One of the issues less frequently discussed when we look at the impact of climate change is how it impacts our national security at a tangible level. In 2017, the Pentagon published a report highlighting that rising sea levels were having an impact on the functionality of its Norfolk shipyard, the largest naval facility in the world. In the last century, sea levels at Norfolk have risen by 1.5 feet and remediation works totalling $300 million are now under way. I know how much work all our services are doing to move to net zero, but remedial works will be necessary. Can the Minister assure the House that the relevant discussions are under way and will be fully funded?
I move on to our energy supply. One of the consequences of extreme temperatures is an increased demand for energy for both air conditioning and other forms of cooling, as well as a need for enhanced heating, for longer periods in both domestic and business premises. What long-term assessments have the Government made of these increases in demand, both in the additional energy that would be required to power new units—earlier this year, a coal power station was put on standby in case air-con use caused a surge in power usage, although evidently that has not been a requirement for us this summer—and the potential longer-term consequences of relying on systems that expel hot air into the environment?
On housing infrastructure, today the Government announced that they plan to meet their manifesto commitment to build 1 million houses before the next general election, seemingly by focusing on urban regeneration using permitted development rights. Putting aside the practicality and the politics of this rehashed commitment, the announcement does lead to some questions following on from the recent report from the Climate Change Committee, as outlined by the noble Lord, Lord Deben. The committee stated that its confidence in the Government to meet their medium-term targets had decreased over the last year. Specifically on our housing infrastructure, it noted the importance of updating building regulations to ensure that new homes meet higher environmental standards. Can the Minister assure the House that these will be expedited to apply to all newbuilds?
Regarding our current housing stock, it has been reported that a third of the funding pot allocated for improved insulation and green energy installations has yet to be spent. In light of recent reports suggesting that the Energy and Utilities Alliance is seeking to delay the transition to heat pumps, can the Minister confirm that the Government will not be swayed and that they are committed to delivering more sustainable housing?
A recurrent theme of today’s debate is that climate change is an international issue, that unless we work with others to protect our natural resources we will all fail, and that it will be harder for smaller and less wealthy countries to meet their commitments. During the passage of the Financial Services and Markets Bill, the Government resisted an amendment to increase transparency around financial institutions’ investment in firms that contribute to deforestation. Ministers eventually offered a compromise, but the review may not surface for many years. Given the obvious urgency, can the Minister confirm a timescale for the review?
The issue of climate change is all-encompassing and increasingly terrifying. I would like to conclude in a slightly more positive manner. As this is one of the last debates before the Recess, I wish your Lordships a relaxing and enjoyable break.
