Harmonized Commodity Description and Coding System (HS) 2017. Methodology:Bilateral trade flows of environmental goods are estimated by aggregating, by partner country, HS 6-digit commodities identified as environmental goods based on OECD and Eurostat, The Environmental Goods & Services Industry: Manual for Data Collection and Analysis, 1999, and IMF research. Total goods imports and exports by partner country are estimated by aggregating all commodities. Environmental goods trade balance by partner country is calculated as environmental goods exports to a given partner country less environmental goods imports from a given partner country. A positive trade balance means an economy has a surplus in environmental goods with a given partner country, while a negative trade balance means an economy has a deficit in environmental goods with a given partner country.Total trade in environmental goods by partner country is calculated as the sum of environmental goods exports to a given partner country and environmental goods imports from a given partner country.Methodology Attachment Environmental Goods Harmonized System Codes
