Assumptions and methodology
The Exponential Climate Action Roadmap is based on backcasting, meaning that we have charted out how emissions need to decline and investigated how fast different solutions need to be implemented to get us there. Emissions reductions are set for each sector of the global economy to follow the Carbon Law of halving each decade from 2020. This background document explains the backcasting model, sectoral baselines, and the sources we have drawn solutions from in more detail.  More details…

Trajectories in detail
We assessed 76 climate solutions, sorted in 33 overarching solution categories, which together provides a halving of emissions for all sectors. This document shows in detail all the solutions that were included and how much each provided.  More details…
