The ten most important short-term steps to limit warming to 1.5˚C

Climate Action Tracker Briefing

Published: 16/11/2016

Limiting global temperature increase to 1.5°C requires major transformations that need to begin immediately. In this brief, the Climate Action Tracker (CAT) provides insights on the ten most important steps that need to be taken in specific sectors in the short term—to 2020 and 2025—if the Paris Agreement temperature goal is to be met.

The CAT team used modelled scenarios to provide guidance on what needs to happen in each sector. The stringency of the 1.5°C limit significantly constrains the degrees of freedom to spread emission reductions across sectors, countries and over time.

Efforts in all of the key sectors that begin by 2020, and accelerate by 2025, will be needed to reach zero globally aggregated carbon dioxide emissions by mid-century, and zero greenhouse gas emissions overall roughly in the 2060s.

For all ten elements the Climate Action Tracker shows that there are signs that a transition of this magnitude is possible: in many cases it’s already happening. Achieving these ten steps in the period to 2020 and 2025 would put the world on a pathway to limit global temperature increase to 1.5°C.
