Climate Interactive and MIT analyzed Paris pledges and mid-Century strategies of different countries.  The pledges themselves are not capable of limiting global temperature increases well below 2° Celsius.  However, they identified 600 pathways that can.

Climate Interactive analyzed the latest nationally-determined contributions to global cuts in the greenhouse gas emissions.  Assuming the contributions are made in full, atmospheric CO2 is projected to reach about 670 parts per million (ppm) and global average temperature increase is projected to reach about 3.5° Celsius above pre-indutrial levels.

Climate Interactive did not post underlying data for its analysis when the above graphic was updated on December 11.  However, prior analyses show a continual rise in global greenhouse gas emissions throughout the 21st Century until 2100 when projections stop.  That is, the projections do not indicate stabilization of global emissions, atmospheric greenhouses gases or global temperature.
