Japan and Taiwan share a common demographic challenge — shrinking, aging populations that are quietly reshaping how we consume, produce, and impact the environment. Rising medical demand, shifting household structures, and generational differences in lifestyle all leave distinct marks on our collective carbon footprint.

This talk dives into how Environmentally Extended Input-Output Analysis (EEIOA) and Life Cycle Assessment (LCA) can quantify the hidden environmental costs of everyday household consumption — and how these footprints vary across generations.

As we navigate both a climate crisis and a demographic shift, what does a truly sustainable society look like? Join us to explore the data — and the path forward.

日本與台灣同樣面臨少子化與人口老化的雙重壓力，這不僅衝擊社會保險體系，更悄悄重塑了整體社會的消費與供給結構——從醫療需求的激增，到各世代截然不同的生活型態，都在影響地球的生態。

本次講座將介紹如何透過「環境延伸投入產出分析」與「生命週期評估」，量化家庭日常消費所帶來的直接與間接碳排放，並進一步分析不同世代家庭的碳足跡結構，為永續消費與生產政策提供數據基礎。

在氣候危機與人口結構改變雙重挑戰下的時代，我們該如何找到兼顧環境與社會的永續路徑？
