We have to decarbonise completely, and we have to do it yesterday. If you're in any doubt about that, look at the recent Pathway Report commissioned by Polestar and Rivian in collaboration with Kearney, using open-source data, which forecasts that, on current trajectories, humanity will have exhausted its forever global carbon budget by 2035. After that point, my friends, we will overshoot the Intergovernmental Panel on Climate Change (IPCC)'s 1.5-degree limit by 75 per cent by 2050.
