Bruckner, B., Hubacek, K., Shan, Y. et al. Impacts of poverty alleviation on national and global carbon emissions. Nat Sustain 5, 311–320 (2022)

Objective:

• Can we lift millions of people out of poverty while controlling carbon emissions

Case:

• Global countries

Methodology:

• MRIO
• Matching GTAP and WBCD
  • $B^{2n+1} = diag(R^{2n+1})B^{2n}$
  • $B^{2n+2} = B^{2n+1} diag(S^{n+1})$

Data Source: partial open

• Expenditure dataset: WBCD, 116 countries and 201 expenditure bins
• GTAP

Findings:

• The highest country-average carbon footprints in high-income countries

• The consumption of the bottom half of global carbon emitters was contributing only one-tenth of global carbon emissions, while consumption of the top 10% was contributing almost half of all emitted CO2

• Consumption of people living in poverty is associated with an especially small part of carbon emissions
• Poverty alleviation is possible with minor increases in global carbon emissions
