How big are the new climate pledges from the US, UK, EU, Canada & Japan?

I reckon they could cut emissions in 2030 by roughly an extra 2bn tonnes of CO2e

That's quite a lot…

…but still tiny compared with the 12-32GtCO2e "emissions gap" to 1.5 or 2C

This is very much a back-of-the-envelope number and depends what you assume would have happened, before the new pledges.

We can expect to see more sophisticated estimates from @climateactiontr & @UNEP

@climateactiontr @UNEP Also – this assumes the new ambitions are turned into reality

That's very much a big "if"

here's the @climateactiontr analysis
