Rather good BBC1 programme on the impact of flying, cheap flights in the UK, and the illusion of SAFs, offsets and so on. Justin Rowlatt and Fran Scott present. Dieter Helm lays down the truth about offsets and markets. And a series of liars spin yarns. Some look remarkably unconvinced by their own bullshit. #flyingless https://www.bbc.co.uk/iplayer/episode/m001zq7n/what-they-really-mean-for-you-cheap-flights
