UK Extreme Heat

Baroness Hayman Excerpts

Thursday 26th June 2025 Lords Chamber

[Baroness Anderson of Stoke-on-Trent (Lab)]

I thank my noble friend. As a former trade union officer, this is something that I have discussed every summer in my adult life. My noble friend is aware of the current situation with regard to the Workplace (Health, Safety and Welfare) Regulations, which require employers to provide a reasonable indoor temperature in the workplace. Obviously, what is reasonable depends on what work you are doing and where you work, which is why in the Moses Room yesterday we had to have the doors open and the fans on. I think it is appropriate that appropriate mitigations are made, but my noble friend will be aware that these conversations are ongoing, and the very nature of this Question ensures that I had yet another conversation about it yesterday.

[Baroness Hayman (CB)]

I declare my interest as a director of Peers for the Planet. Should we not be aware, in discussing this Question, that extreme heat affects us in certain ways, but extreme heat overseas can have devastating effects on crops, with drought, famine and population changes and movements, so we should not treat this lightly? Alongside the need for mitigation, resilience measures and everything that the Minister has said, is not the proof of the increased likelihood of these sorts of episodes an absolute clarion call for this country not to withdraw or retreat from our commitment to domestic progress and international leadership on fighting further climate change?

[Baroness Anderson of Stoke-on-Trent (Lab)]

The noble Baroness raises excellent points about why we are having to have these conversations in the first place. It is clear that the chance of 40-degree days in the UK is now 20 times higher than it was in the 1960s, and we have a 50:50 chance of a 40-degree day within the next 12 years. This is changing within the UK, and obviously that has a knock-on effect on climate elsewhere, which is why we need to take this extremely seriously in terms of our impact on the environment and why I was so pleased to see in our industrial strategy, which we published on Monday as part of our plan for change, that we made commitments to green jobs, investment in green energy, embedding net zero and challenges to climate change within our plans for government across every department.
