A freedom of information request by Carbon Brief has revealed the risks to prisoners in England and Wales from overheating in summer, according to internal assessments by the Ministry of Justice.
Under a low-emissions scenario, consistent with keeping global warming below 2C by 2100, the assessment showed that 96 of the 122 prisons and young offenders institutions in England and Wales will be at “high” (red on the graphic) or “very high” (dark red) risk of overheating in the summer months over 2020-39.
