With the Paris climate goals in prospect and the latest IPCC reports in mind, it is urgent and necessary that the healthcare sector also looks at how to limit global warming. Healthcare is a major producer of greenhouse gasses, air pollution and waste. In addition, it uses a lot of raw materials and energy. Both the World Health Organization, the World Dental Federation and national parties are trying to draw up an agenda based on goals to make the healthcare sector more sustainable. English research shows that the largest emissions in oral care are caused by travel, purchasing and use of materials and energy use in practice. Based on these topics, steps can be taken to become more sustainable. The e-book 'Sustainable oral healthcare practice' provides a good starting point for this.
