Ou, Y., Roney, C., Alsalam, J. et al. Deep mitigation of CO2 and non-CO2 greenhouse gases toward 1.5°C and 2°C futures. Nat Commun

Objective:

• Explore how CO2 and non-CO2 GHG mitigation pathways jointly affect the ultimate level of temperature change

Case:

• Global

Methodology:

• IAM: GCAM

Data Source

• Emission: CEDS
• Non-CO2 mitigation: EPS

Findings:

• Global CO2 and non-CO2 GHG emissions continue grow throughout the century, driven by increasing population and GDP

• When further accounting for non-CO2 abatement measures, non-CO2 emissions show a decreasing trend

• When additionally including system-wide non-CO2 mitigation measures in comprehensive GHG abatement, industrial and cooling-related HFCs emissions are heavily reduced
