Limiting the rise of the average global temperature to less than 1.5 Degrees Celsius is vital but the question is how do we achieve this? In short, we must keep total global emissions between 2018 and 2050 below 570 gigatonnes of CO2 equivalent with two important stage posts en route. First, by 2030, we need to cut emissions by 23 GT and then, ultimately, every tonne of carbon emitted needs to have an equivalent tonne of carbon removed from the atmosphere, in other words, achieving net zero, by 2050.
