eaSi-system - Framework for systematic SDG impacts assessment

Value chain modelling

  • Global value chains
    For the global value chain modelling, we combine input-output tables and bilateral trade data. Moreover, we include technology specific data related to the value chain of the technology. To estimate the Rest of the World impacts, we perform econometric modelling. In doing so, we create static “what-if” scenarios, where we estimate both short-term investment effects (addressing the construction/investment phase of the technology) and long-term structural change effects (addressing the use-phase of the technology).
  • Material value chains
    We also take into account the specific and detailed material value chains of the technology. In the model, we disaggregate the relevant materials. We split the energy mining (oil, gas and coal) based on the energy balances and bilateral trade. In addition we map the different materials needed for the new technologies to link the location and trade of ore mining – refining – manufacturing value chains of specific materials (e.g. cobalt, rare earth metals, lithium, nickel and copper).

  • We also use other value chain modelling tools, such as:
    • Material flow analysis
    • Life cycle assessment
    • Life cycle costing
    • Techno-economic analysis
    • Value-chain optimization
    • Computable general equilibrium models
    • Supply chain managment / logistics
    • System dynamics modelling
