At #utsg2023 (a UK transport conference in Cardiff), and had one of the best and most relevant opening talks I’ve been to - from Lee Waters, Wales Deputy Minister for Climate Change and also Transport - because they've put transport under climate change.
Among other interesting things - they've just changed the default urban speed limit in Wales to 20mph rather than 30. Done a major review of road infrastructure investment.

Someone asked about closing Cardiff Airport and he said that's not on the table yet - still perceived as too many economic + 'national prestige' reasons not to stop subsidising air travel until the rest of the UK does
In his opinion, in a state of climate emergency, investment in buses is going to give much more climate reduction per dollar, quicker, than investment in rail in Britain

@timrichards he may also have been thinking more about shorter trips, between adjacent towns and <1-2 hours, say.
