Global emission reduction trajectories associated with a 66% chance of avoiding more than 2°C warming by starting year. Solid black line shows historical emissions, while dashed black line shows emissions constant at 2016 levels. Data and chart design from Robbie Andrew at CICERO and the Global Carbon Project.

2018 global emissions hit 36.2 gigatonnes, globally. Ideally, that suggests a lowering to 20% around 2040 to 2045.
