Common Ground Publishing LLC. Preparation: Please read the assigned article and prepare answers to the following questions by summarizing in your own words: What is an 'upstream supply chain'? Interpret the large numbers found on the diagonal in Table 3, such as the 2057 AU$m transaction within the Textile sector. Describe the main application of environmental input-output analysis. Lecture 2: Group Presentation Date: April 18 Content: Online group presentations on various topics related to Industrial Ecology, focusing on specific keywords of interest. Featuring a guest lecture by the senior editor of Nature on Springer Nature. (The online link will be provided in advance through ITC-LMS.) Lecture 3: Current Research Interests in Industrial Ecology Date: April 25 Content: Introduction of major trends in Industrial Ecology research, based on keywords proposed by each group in Lecture 2. Introduction to scientific research methods in industrial economy, including topic definition, data collection, quantitative research, and summarization. Lecture 4: Data Collection and Quantification Analysis in Industrial Ecology Date: May 2 Content: Online session on group-based presentations using the IPAT model for data collection and quantification analysis. This lecture aims to enhance understanding of conducting environmental research questions in chosen fields. (The online link will be provided in advance through ITC-LMS.) Lecture 5: Basics of Input-Output Analysis Date: May 9 Content: Introduction to Leontief’s conceptual input-output framework, development of fundamental mathematical relationships from the interindustry transaction table, exploration of key assumptions of the Leontief model, and implications of these assumptions. Discussion on national accounts and linear algebra, including data sources, treatment of exports and imports, role of imports, and globalization aspects. Lectures 6 & 7: Basic Mathematics of Input-Output Analysis - I & II Dates: May 16 & May 23 Content: These lectures are part of a series focusing on the mathematical exercises and practices within the context of input-output analysis. They cover the introduction to, and extension of, Leontief’s input-output model, highlighting the conceptual framework, mathematical relationships, and practical applications in analyzing regional and global economic activities. Lecture 8: EEIO Analysis Application: Household Consumption and Industry Sectors Date: June 6 Content: Exploration of environmental impact analysis through EEIO, focusing on sustainability concepts, energy-resource-greenhouse gas relationships, and pollution measurement using an input-output table of the global economy. Lecture 9: EEIO Analysis Application: Household Consumption Behaviors Date: June 13 Content: In-depth analysis of the carbon footprint of household consumption behaviors using EEIO, with practical examples and case studies. Discussion on identifying key sectors contributing to household carbon emissions and strategies for reduction. Reading Material: Jiang, Y., Long, Y., Liu, Q., et al. (2020).
