Carbon Brief: COP 30 delegate charts

A couple of quick graphics for our COP30 delegate analysis

A bar chart showing the breakdown of delegates attending COP summits over the years since COP1 both "parties" and "observers" have grown steadily peaking at COP28 in Dubai before falling back. Still The most recent COP has close to 60,000 attendees

A bar chart showing the average gender balance of delegations has improved over time

I think this second chart is a bit of an odd one, and I'm not sure it communicates clearly outside the context of the article. To clarify: what's being shown is the average of the gender split across the national delegations. In a simple situation where country A sends a delegation with 75% men and 25% women, and country B has 25% men and 75% women, we'd have a situation where the average gender split is 50/50. This method doesn't take into account the size of the delegations. If country A has only 4 people and country B has 400, then the conference as a whole will have 103 women and 301 men, a long way from the 50/50 that the published chart would show. Ignoring delegations and just calculating the gender split on total numbers of delegates paints a somewhat less rosy picture, as per this draft version of the chart...

A barchart of the same format but in this one the gender split remain more or less flat over the lst 10 years, peaking at 37% women
