Good morning. It’s quite hard to visualise a number like 646 gigatons. That’s the amount of CO2 emissions which will be produced by 195 major fossil fuel projects currently in the works, and I can tell you that it’s about the same weight as 627bn Volkswagen Polos or 3,230bn Shetland ponies, but that probably isn’t a lot of help.
Luckily, there are more straightforward descriptions available. 646 gigatons in emissions is, on its own, 146 gigatons more than the entire carbon budget available if we are to have a chance of avoiding catastrophic global heating. And the projects that will produce those emissions are known as carbon bombs.
