This technical document provides updated emission estimates for greenhouse gases from ships. According to estimates presented in this study, international shipping emitted 796 million tonnes of CO2 in 2012, which is about 2.2% of the total global CO2 emissions for that year. By contrast, in 2007, before the global economic downturn, international shipping is estimated to have emitted 885 million tonnes of CO2, which is 2.8% of the total global CO2 emissions for that year.
