Building on the success of the three previous editions, HCWH Europe held its annual European Healthcare Climate Summit in October 2022. Supported by the Scottish Government and NHS Scotland, the summit brought together a wide variety of stakeholders to discuss what climate-smart healthcare looks like in practice. In the event report, we describe tangible and replicable case studies from across Europe, which were presented at the summit, giving healthcare providers the opportunity to learn and replicate in their own operations.
