Global Sb emission until 2050 is projected with 3 scenarios based on 2013 EIA outlook.
World countries are divided into 4 regions with similar technology development level.
We use transformed normal distribution function to reflect emission factor variation.
Future Sb emission will peak at 2020–2025 and then decline under 2 control scenarios.
Control of Sb from MSW incineration and coal burning in top 10 countries is critical.
