Modelling Worldwide Polluting Household Energy
At least 2.6 billion people in low- and middle-income countries rely on polluting fuels like wood or coal for cooking, causing dangerous levels of household air pollution attributed to 3.8 million deaths per year by the World Health Organization.
Researchers in the Statistics and Data Analytics group work with the WHO on an ongoing basis to estimate worldwide use of different fuels for cooking, using an advanced Bayesian hierarchical model they developed called the Global Household Energy Model. The WHO uses these estimates in monitoring two key Sustainable Development Goal indicators: ‘Mortality rate from the joint effects of household and ambient air pollution’ (3.9.1) and ‘Population with primary reliance on clean fuels and technologies’ (7.1.2). These estimates also feature prominently in the 2019, 2020, and 2021 editions of Tracking SDG7: The Energy Progress Report.
