The NHS has a substantial carbon footprint. Yet one part of its environmental impact receives relatively little attention: maternity care.
The health service is responsible for an estimated 4% to 5% of England’s greenhouse gas emissions. A 2025 report from the Royal College of Obstetricians and Gynaecologists estimated that selected maternity care activities in England generated about 205,000 tonnes of carbon dioxide equivalent (CO₂e) in 2022–23.
