Today I am very pleased to share a two-part episode on exploring the current and future resource use and climate impact of mobility. In fact, mobility is responsible for a large part of CO2 emissions, energy use and material use both for the construction of vehicles and for its associated infrastructures.

This two part episode is a collaboration with the Urban Mobility Explained (UMX), a YouTube channel powered by EIT Urban Mobility (https://www.youtube.com/@urbanmobilityexplained). You can check out their channel and some of their videos as every week they cover quite broadly environmental and social impacts of mobility and solutions from cities around Europe. 

To explore the resource use impacts of mobility I am glad to welcome Karel Van Acker. Karel is professor in sustainable materials management @KU Leuven. His research develops strategies to realize the circular economy and on sustainability assessments of material life cycles.

=== Quantities mentioned ===

(These numbers may be approximations or projections)

- 80% of EU’s rare earths come from China

- 78% of EU’s lithium comes from Chile (https://eur-lex.europa.eu/legal-content/EN/TXT/HTML/?uri=CELEX:52020DC0474)

- 60% of the future metal demand is from electric vehicles

- Lithium consumption increase between 2020 and 2050:

— x21 globally

— x35 in Europe

- Metal consumed for fabrication (other than steel) : 

— Conventional car: 50kg

— Electric car: 200kg

- Metal consumed per MegaWatt produced (other than steel) : 

—"Clean" energy: 16000kg

—Coal/gas: 2000kg

- Seabed mining could supply 10-20% of the world's Nickel

Hello everyone and Welcome to the Circular Metabolism podcast, the bi-weekly meeting where we have in-depth discussions with researchers, policy makers and practitioners to better understand the metabolism of our societies (or in other words their resource use and pollution emission) and how to reduce their environmental impact in a systemic, socially just and context-specific way.
