Health system decarbonization on obstetric and newborn units

The healthcare industry makes up 4.6 % of greenhouse gas (GHS) emissions worldwide. Although it is not known what proportion of GHGs come from obstetric and newborn units, newborns and pregnant individuals are likely to face some of the largest consequences from climate change. We review the literature in the areas of decarbonization on labor and delivery (L&D) and neonatal units and describe innovations from the fields of surgery and anesthesia. Best practices for L&D include refining disposable equipment packs, decreasing the use of single-use medical devices, adequately triaging waste, and decreasing the use of potent anesthetic gases such as nitrous oxide and desflurane. In neonatal settings, similarly triaging waste and decreasing the use of plastics containing endocrine disrupting chemicals can lower the carbon and environmental footprint and improve neonatal health. Additionally, avoiding unnecessary cesarean deliveries and increasing breastfeeding practices are also likely to improve the carbon footprint of L&D and neonatal units.
