For example, clean water, sanitation and hygiene are essential to human health and well-being. Unsafe water and sanitation and a lack of hygiene caused an estimated 870,000 associated deaths in 2016 . Only 71% of the global population has access to safely managed drinking water services; only 45% of the global population has access to safely managed sanitation services; and 60% has basic handwashing facilities in their home. About 25% of healthcare facilities lack basic water services, exposing workers and patients to higher infection risks. More than 80% of countries reported in 2018 that they lacked sufficient funding to meet national WASH targets. As detailed in Section 7.2.2.2, Box 7.3, Section 7.3.1.4 and Section 7.4.2.3, the burden of climate-sensitive WBDs would be reduced if WASH targets were met.
