The global carbon budget left for not to exceed 1.5-degree warming is alarmingly low, only around 300-400 gigatonnes of CO2, meaning no more than 10 years at the current global yearly emissions level of 40 gigatonnes. Moreover, the global average per capita emissions are ~5 tonnes per year, which is equivalent to the GHGs from just private transport in Reykjavik when including long-distance travel. While flights dominate these emissions in Reykjavik, private cars contribute over 2 tons per year per capita - a massive amount in global terms and given the rapidly shrinking carbon budget for 1.5-degree warming. The transformation of the transport sector, therefore, needs to be rapid and profound.
