It describes the present limitations of air-quality monitoring and emissions estimates, then develops scenario inputs from projected population growth, rising incomes, and urbanization to model agriculture, energy (including households and transport), and waste pathways. Using emissions inventory methods and integrated modelling frameworks (including atmospheric chemistry and Earth system simulations), it projects substantial increases in pollutants such as PM2.5 and ozone, associated with large cumulative premature mortality over 2015–2063 and widespread reductions in crop yields, with notable losses for staple crops by mid-century.
