Heat summary of Chapter 14
The UK has committed to reaching net zero greenhouse gas emissions by 2050. There must be a careful consideration of how net zero policies are carried out, to make sure they do not accidentally make the effects of hot weather worse.
Improvements in building insulation as part of net zero policies could reduce energy consumption and greenhouse gas emissions. However, this might also increase the risk of homes becoming too hot during hot weather, if ventilation is not improved at the same time.
Making more green spaces in cities, such as planting trees, is highlighted as a nature-based solution related to climate action policies. This can help reduce the urban heat island effect, and also provides cooling during heatwaves. Similarly, protecting existing forests and planting new trees in order to sequester carbon can inadvertently provide additional habitat for vectors that carry diseases. Equally, more opportunities to spend time in nature can have mental health benefits.
The shift towards walking, cycling and using electric vehicles can reduce greenhouse gas emissions, however the increase in outdoor activities might expose more people to heat during hot weather, especially if adequate shading and cooling infrastructure is not in place.
