The Health & Safety Executive (HSE) is the United Kingdom's national regulator for workplace health and safety. It is responsible for the encouragement, regulation, and enforcement of workplace health, safety, and welfare, and for research into occupational risks in Great Britain. HSE works to reduce work-related death, injury, and ill health.

HSE is committed to sustainability and has integrated environmental considerations into its operations. The organization aims to minimize its carbon footprint and has implemented various initiatives to reduce energy consumption and waste. However, detailed information on specific sustainability certifications or ESG reports is limited.

HSE's approach to sustainability includes promoting safe and sustainable working practices across industries. By ensuring compliance with health and safety regulations, HSE indirectly supports environmental sustainability by preventing accidents and incidents that could lead to environmental harm.

Overall, while HSE's primary focus is on health and safety, it recognizes the importance of sustainability and strives to incorporate it into its regulatory framework and operational practices.
