Net-zero greenhouse gas mitigation potential across multi-tier supply chains

This dataset suports the fidings of the current Sicence Based Target initiative scope 3 standards emission coverage across four major production countries: the United States, South Korea, China and Mexico. Environmentally-extended input-output models are used to generate all tables in the dataset, which is presented as an .xlsx file, consisting of five sheets with the following infomation: table 1: percentage of emissions intensitity of four countries by tier and scope. table 2: companrison between emissions intensity and total emissions weighted by final use. table 3: composition of weighted total emissions by tier and scope. table 4: emissions coverage of Science Based Target initiative's scope 3 standards. table 5: case study of two sectors.
