Teleconnecting Consumption to Environmental Impacts at Multiple Spatial Scales

  • Time: 1:00pm - 2:00pm
  • Location: Room 325 (NVC)


Globalization increases the interconnectedness of people and places around the world through markets, flows of capital, labor, services, information, and human migration. In such a connected world, goods and services consumed in one country are often produced in other countries and exchanged via international trade. Thus, local consumption is increasingly met by global supply chains that often involve large geographical distances. As such, local consumption can have negative impacts on both the local and global environment, contributing to climate change, water scarcity, deforestation and other land conversions, all of which impact important ecosystem services.

In this talk, I will first compare bottom-up and top-down approaches for life-cycle assessment. Then I will present some results on consumption-based CO2 emissions, land use, and water use across 129 countries/regions based multi-regional input-output analysis (MRIO), a typical top-down approach.
