This is the 2024 update of the Compendium of WHO and other UN guidance on health and environment. The Compendium is a comprehensive collection of available WHO and other UN guidance for improving health by creating healthier environments. It provides an overview and easy access of more than 500 actions, and a framework for thinking about health and environment interventions. It covers a broad range of areas such as air pollution, water, sanitation and hygiene, climate change, chemicals, radiation, or food systems. Guidance is classified according to principal sectors involved, level of implementation (national, community, health care), the type of instrument (taxes, infrastructure etc.) and the category of evidence. The Compendium compiles existing guidance from hundreds of documents in a simple and systematized format. To ensure the most up-to-date information is provided to the end users, the Compendium is updated on a regular basis and incorporates the latest major WHO or other UN guidance on health and environment. The target audience includes any decision-makers with relevance to health and environment, and those assisting them (such as mayors, staff in ministries, UN country staff etc.). The Compendium has been prepared by WHO in cooperation with UN Environment, UNDP and UNICEF.

WASH in health care facilities is essential for quality care – on this there is universal consensus. Many countries are taking action, but more collaborative, focused and expansive effort and investments are needed. This report focuses on global and national efforts and progress to improve water, sanitation, hygiene (WASH), cleaning and health care waste management in health care facilities. It builds upon the first update of progress published in 2020. In addition, in response to demands from countries and health actors on providing a consolidated package of information and interventions on climate-resilient and sustainable infrastructure services in health care facilities, data on electricity and examples of electrification are included. It includes a summary of country progress in implementing national actions (“practical steps”) articulated in the 2019 World Health Assembly Resolution on WASH in health care facilities, drawing on data from a “country tracker” and provides insights on successful approaches and challenges from country experiences in improving and sustaining WASH in health care facilities. The main audiences for the report are national health authorities; those engaged in WASH and infection prevention and control (IPC) in health care facilities, including ministries of health, water, infrastructure, energy and financing; global and national WASH and health partners, including donors and health funders; and actors working on climate-resilient and low-carbon health care facilities and health systems.
