Document Summary
Limiting global temperature increase to 1. 5 c requires major transformations that need to begin immediately. We provide 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. We used modeled scenarios to provide guidance on what needs to happen in each sector. The stringency of the 1. 5 c limit significantly constrains the levels of freedom to spread emission reductions across sectors, countries and over time. Efforts in all of these sectors that begin by 2020, and accelerate by 2025, will be needed to reach zero carbon dioxide emissions by mid-century, and zero greenhouse gas emissions overall roughly in the. For all ten elements we show there are signs that the transition of this magnitude is possible: in some specific cases it"s already happening.
