Page 1 of 45 Reducing Evaporative Emissions - the Largest Source of VOC Emissions Leading to Haze, and Ozone Formation in China's Major Cities: A Macro and Micro Analysis with Information on International Experience and Related Implications for China Page 2 of 45 EXECUTIVE SUMMARY VOC Emissions are causing 20-30% of the and 47% of the haze problems in China. Additionally, a large fraction of these VOCs is evaporated gasoline from automobiles. The European-based Evaporative Emissions standards, combined with Stage II vapor recovery, are providing China with only 46% control efficiency of combined diurnal, running loss, refueling, permeation, and hot-soak Evaporative Emissions .
