Rode, A., Carleton, T., Delgado, M. et al. Estimating a social cost of carbon for global energy consumption. Nature 598, 308–314 (2021)

Objective:

  • Design a fully modular bottom up architechture, Data-driven spatial climate impact model to develop partial socia cost of carbon (SCC) for individual subsectors of the global economy

Case:

  • Global countries

Methodology:

  • DSCIM mode:
    • Match data
    • OLS: historical temperature distributions on national annual per-capita energy consumption
    • Coupled model intercomparison project phase 5
    • damage function
    • probabilistic climate-carbon cycle model

Data Source

  • Energy consumption: IEA (0.25*0.25), electricity and direct fuel consumption across reisidential, commercial, industrial and agricultural end-uses in 146 countries
  • Daily temperature: Global meteorological forcing dataset
  • Future temporature: Nasa earth exchange global daily downscaled projections
  • National income per capita are derived from the shared socioeconomic pathways

Findings:

  • Population’s income per capita is a key determinant of how its end-use energy consumption responds to temperature
  • U-shaped electricity-temperature relationship can be observed, and L-shaped fuels-temperature relationship is identified; these impacts can be enhanced by income growth
  • Population adapt to their long-run climate in ways that change their energy consumption during hot and cold periods
  • Most of the world is expected to increase net annual per-capital electricity consumption and decrease consumption of other fuels due to climate change
  • Hot and wealthy locations show large net increases in electricity consumption
  • 1 t of CO2 emitted today generates a total energy expenditure burden valued at -US $13.93 to -US0.69
