Pitch

Based on Pathways to Deep Decarbonization reports for Other Developed Countries, prepared by the Deep Decarbonization Pathways Project.


Description

Summary

This seed proposal is based on several Pathways to Deep Decarbonization reports relevant to Other Developed Countries, reports prepared in 2015 by the Deep Decarbonization Pathways Project (DDPP). The proposal was prepared by a member of the Climate CoLab staff. We invite other CoLab members to link to this proposal or to use it as a starting point for creating new proposals of their own. DDPP has not reviewed or endorsed this proposal.

DDPP is a collaborative global research initiative to understand how individual countries can transition to a low-carbon economy consistent with the internationally agreed goal of limiting anthropogenic warming to less than 2 degrees Celsius (°C).

It was convened under the auspices of the the Institute for Sustainable Development and International Relations (IDDRI) and the Sustainable Development Solutions Network (SDSN).

The country teams include researchers from leading institutions in their respective countries, acting independently; they do not represent the official positions of their national governments.

The Other Developed Countries included in the DDPP exercise were: Australia, Canada, Japan, Mexico, and South Korea (reports for the first three countries have been completed, and reports for the latter two were pending as of October 2015).

In total, the Other Developed Countries included in DDPP were projected to reduce their emissions from the energy sector (which was the primary focus of DDPP) from approximate 5.5 Gigatons (Gt) of CO2 in 2015 to approximately 1 Gt in 2050.   

These reductions are expected to be achieved through a combination of increased efficiency, decarbonization of the electric power sector, and switching from direct burning of fossil fuels to low-carbon electricity.  

For a graph that shows the emission pathways for the all Other Developed countries as a group, see DDPP, Pathways to Deep Decarbonization in Australia, page 15.

Explanation of the emissions scenario calculated in the Impact tab

The EMF-27 model was used, and variables were selected to align with the DDPP projection for Other Developed Countries:

  • Policies in place to achieve 450 parts per million atmospheric concentrations of CO2
  • Energy efficiency increases at nearly double historical rates
  • No constraints on low-carbon energy sources
     

These resulted in reductions in CO2 emissions from energy by 2050 in line with the DDPP report.
