Climate change mitigation potential in sanitation via off-site composting of human waste

Nature Climate Change, Published online: 01 June 2020; doi:10.1038/s41558-020-0782-4 Human waste in slums is often collected untreated in pit latrines, which emit GHGs and have negative impacts on human health. If adopted in slums globally, off-site composting could reduce methane emissions from the sanitation sector by 13–44% while improving public health.
