Nghiên cứu này sử dụng các bảng cân đối liên ngành (còn gọi là bảng IO - input output table) các năm 2007, 2012 và cập nhật cho 2018 để xác định hiện trạng sản xuất nhựa và tiêu dùng nhựa (theo các ngành kinh tế) của Việt Nam trong giai đoạn 2007-2018. | Sử dụng bảng IO trong phân tích gánh nặng môi trường của ngành bao bì nhựa PET tại Việt Nam VNU Journal of Science Earth and Environmental Sciences Vol. 36 No. 2 2020 90-98 Original Article Using IO Table in Analyzing the Environmental Burden of PET Plastic Packaging Industry in Vietnam Ta Thi Yen1 2 Nguyen Thi Anh Tuyet1 1 Hanoi University of Science and Technology 1 Dai Co Viet Hai Ba Trung Hanoi Vietnam 2 Hanoi University of Natural Resources and Environment 41A Phu Dien Tu Liem Hanoi Vietnam Received 23 February 2020 Revised 16 April 2020 Accepted 09 June 2020 Abstract Plastic industry plays an important role in the economic development. The PET plastic packaging industry is the largest segment of the plastic industry accounting for of GDP of Vietnam s plastic industry. However the current production and consumption of PET in Vietnam are having significant environmental impacts. This study uses input-output tables IO tables in 2007 2012 and updated for 2018 to determine the current status of plastic production and plastic consumption by economic sectors in Vietnam during the period of 2007 - 2018. At the same time the research integrates IO tool and LCI to identify the environmental burden in the PET plastic packaging life cycle through PET s demand of other economic sectors. The results show that the two biggest PET plastic consumers are food processing sectors and electronics sectors and these industries are also responsible for the highest indirect GHG emissions. This result can form the basis for developing a sustainable plastic packaging production and consumption strategy for Vietnam. Keywords IO table LCI plastic emission economic. Corresponding author.
