The printing industry has always been the key source of volatile organic compound(VOC) emissions in China. However, owing to complexity raw materials and processes, fine emission inventory its future reduction potential VOCs from have not well characterized. In this study, existing factors were improved, considering neglected semi/intermediate VOCs(S/IVOCs). An period 2011-2020 China was compiled. Through scenario analysis, under different scenarios 2030 predicted, analyzed. increased first then decreased 2011-2020. Compared with that 2011, by 29.6% 2020, an average annual growth rate 3.0%. This mainly due increasing consumption demand market lack effective measures for integrated management VOCs. 2020 861 Gg. Gravure packaging processing two most important accounting 52.0% 28.7%, respectively. Guangdong, Jiangsu, Zhejiang largest contributors VOC emissions, 44.12% total emissions. 1187 Gg, 684 362 Gg baseline scenario, general control strict 37.9% 20.6% 57.9%, are still focus reduction.
