Fig. 5: Comparison of overall NPV economic costs for 3 years in terms of the world total and aggregated regions, and the carbon budget.
From: Climate change mitigation costs reduction caused by socioeconomic-technological transitions
All economic values are expressed in NPV from 2020 to each year of analysis. The “Mitigation cost in default scenarios” corresponds to the mitigation cost under default scenarios. “Benefit of socioeconomic-technological transition in mitigation cost” is derived from the GDP loss differences between the IST and default scenarios. “Climate change impacts” are the direct output of the emulator using the global mean temperature, which includes market and non-market sectors. “Air pollution mortality changes” are derived from the PM2.5 concentration generated by a chemical transport model, which was fed into the health impact function and monetised by the VSL (Value of Statistical Life) and the relative changes to baseline scenarios are presented.
