We welcome the stated aim of delivering an in-person summit and agree that this would allow for the most effective engagement with the widest number of countries— particularly those most at risk of climate impacts. However, the Government must also plan for the distinct possibility that large parts of the summit will have to be moved online or downscaled because of prevailing risks from covid-19. We recommend it outlines the steps it is taking during planning to make COP26 a success regardless of the format. We further welcome the intention to explore how digital events can increase participation in the summit and request further details as they become available.
