Abstract
This paper evaluates CO_2 emissions generated during the manufacturing phase of global production network and discusses requirements analysis of green sustainable policies of global production network to prevent carbon leakage arising from transnational production. It calculates CO_2 emissions from electricity used in manufacturing, emissions during transport from mining to manufacturing countries and emissions during transport from manufacturing countries to market. A case study of electric vehicle (EV) production includes outcomes calculated CO_2 emissions in the manufacturing phase and transportation phase: for production in China, India, Thailand, Germany, Japan and Mexico to market in Japan, German and Singapore. It is illustrated that CO_2 emissions during manufacture of EVs vary significantly, depending on the carbon intensity from electricity generation and each country's technical efficiency, and transport has a minor influence on emissions.
