Figure 1. — Quantification and prevention of premature deaths resulting from long-term PM_2.5 exposure as a result of achieving different clean air targets. (a) Premature deaths resulting from long-term PM_2.5 in China at current levels (2013–2020) and projected reductions under the World Health Organization (WHO) interim target (IT) or air quality guidelines (AQGs) scenarios. The double-arrowed lines show the additional avoidable deaths (AADs) resulting from the last-step and big-step scenarios based on 2020 PM_2.5 levels; note that the AADs varied depending on different PM_2.5 baselines. (b) AADs attributable to long-term PM_2.5 exposure by achieving the new AQGs (NAQGs) compared to the previous AQGs (last-step scenario) or National Ambient Air Quality Standards (NAAQSs) of China (big-step scenario) under different PM_2.5 baselines, from 2013 to 2020. (c) County-level maps of the spatial distribution of AADs under the last-step and big-step scenarios for China for 2013 and 2020. In panels (a) and (b), the error bars represent 95% confidence intervals, produced from Monte Carlo simulations. In panel (c), data for the Taiwan Province and some small islands are not available.
