Mayor of London Sadiq Khan and Mayor of Rio de Janeiro Eduardo Paes will welcome more than 300 of their fellow city leaders to the C40 World Mayors Summit in Rio today with a single clear message: it is time to move from the era of climate negotiation to the decade of delivery, with cities taking the lead.

The mayor of Rio de Janeiro, Brazil, says COP30 must include the voice of subnational governments.
