The world leaders who congregated in Sharm El Sheik for the first two days of COP27 have left and, whilst the climate negotiators get to work, the thematic days of the conference have begun.

Wednesday was finance day, with a host of side events around the pavilions discussing the often thorny issues surrounding climate finance. It was also the day that former US Vice-President Al Gore launched a project to provide accurate, granular emissions date, and revealed that, in many cases, emissions are much higher than previously reported.
