This year’s Global Carbon Budget is out, and it is a treasure trove of charts for anyone who really wants to understand human carbon emissions. The budget is the work of 77 people, from 46 organisations in 14 countries. With that many wonks working together they simply suck up all the oxygen. So all the units are gigatonnes of carbon (GtC), each of which is equal to 3.664 GtCO2 (carbon dioxide is the unit more familiar outside scientific circles). This post is a Wonkblog style overview of where man made carbon emissions come from, where they go and what that means.
