COP26: Limiting Global Temperature Rises

Ben Lake Excerpts

Thursday 21st October 2021 Commons Chamber

[Ben Lake (Ceredigion) (PC)]

I would like to echo the words of my hon. Friend the Member for Brighton, Pavilion (Caroline Lucas), who quoted the IPCC’s most recent report, which stated that

“unless there are immediate, rapid and large-scale reductions in greenhouse gas emissions, limiting warming to…1.5 °C…will be beyond reach.”

Today, we live in a world with global warming of 1.1°C, yet it is a world already ravaged by forest fires and increasingly frequent extreme weather events. It is a world made poorer by rapid biodiversity loss and made more geopolitically unstable by profoundly changing climate patterns. Despite that, my generation may be living through the last days of relative climatic, environmental and ecological stability. It is this realisation that makes COP26 and its outcome so important.

Like others, I can see that the Government’s net zero strategy published this week was an important but overdue intervention. Its ambitions for renewable electricity generation are laudable, the emphasis on decarbonising household heating welcome, and the desire to reduce the greenhouse footprint of our transport sector commendable. And yet, action falls short of the rhetoric, especially when addressing the costs of the transition for households. The heat pump strategy, for example, needs to go further. Indeed, it will benefit only about 0.3% of Welsh households. Instead, greater capital resourcing should be given to the Welsh Government, who are responsible for housing as a devolved competence, so that they can implement a whole-house approach, addressing both insulation and heating supply.

That is just one example, but unfortunately, there are many more, which prompts the question: why? It seems that the answer lies in the Treasury and perhaps its hesitancy to accept the climate crisis for what it is: an existential crisis. It is short-sighted in the extreme for some to suggest that we cannot afford the transition. It is the cost of inaction that is unaffordable. The Treasury’s “Net Zero Review” details that the number of natural catastrophes has risen markedly since the 1980s and Munich Re has calculated that global disasters exacerbated by climate change caused $210 billion-worth of losses in 2020 alone. Meanwhile, the Climate Change Committee found the annual net cost over the next 30 years for the UK’s transition to net zero to be £10 billion, or 0.5% of GDP.

Does the hon. Gentleman agree that we need to find positive ways to allow our constituents to be involved in making our cities and towns greener? For example, the new 110,000-tree Hempsted woods in my constituency will give every schoolchild the chance to plant at least one tree. That will be alongside the green energy from solar, wind and hydrogen that we hope to produce there. Does he agree that this is the sort of local initiative that goes alongside the national commitments?

[Ben Lake]

I am very grateful to the hon. Gentleman for his intervention and I agree wholeheartedly. If we are to get to grips with the crisis, it will require both the national and local action that he described so eloquently.

The cost of inaction is unaffordable. Even if we were to disagree on that point, the alternative—a world aflame, flooded and barren—outweighs any short-term Treasury reservations about the cost of the green transition. To put it simply, we can and must do more. I urge the Government to support the COP26 President in the final weeks before the summit so that we achieve global successes on emissions commitments and ensure that the Chancellor’s forthcoming Budget meets the biggest challenge of our age.
