"17/20 busiest air routes in Europe cover distances <700 km - exactly the kind of distances where city-to-city trains can offer faster, cleaner & more sustainable journeys -- if the right infrastructure exists. #trains #publictransport #highspeedrail "
High Speed Rail like the Eurostar (HS1) can compete with domestic flights in a way that slow local stopping services (which are also mega important!) can't.
If we had more High Speed Rail that would increase the area you can travel to in 6 hours or less - making it more feasible to ban more short haul flight routes!
Look at this view of Great and Green Gable. You cannot see a single tree or shrub. The sheep have eaten everything.
We hiked for 8h on a sunny April day - I don't think I saw a single flower or insect on the peaks.

Aha! Found some trees!
They're growing on small ledges on cliffs near the stream with little grazing pressure.
Well done little guys.

Our article: How could we enable low carbon behaviours to reach #NetZero for food & transport?* ow.ly/urXc50Gm1f3@MarteauTM@NickJChater
*more plant-based diets, active travel & public transport; less driving.

💡Diet and land travel are key sectors for health and sustainability
⛽️Food production is 26% and land travel 12% of global GHG emissions
⚰️Outdoor air pollution leads to more deaths than HIV&malaria combined: nature.com/articles/natur…

Current govt policies are insufficient to rapidly decarbonise & reach #NetZero
We need policies led by evidence and citizens' values. Citizens' assemblies often recommend more ambitious climate policies than govts'.
Crunching some numbers:
🚄#HS2 's construction is 8-14 million tCO2 (~12)
🔌1 electric car (Nissan leaf)'s construction is ~10 tCO2
🚘The UK has ~44.5 million petrol&diesel cars
🤯Replacing them all with EVs would take 445 million tCO2 or *37* HS2s
🚉HS2 = 1.2 million EVs
/1
For context, 10t CO2 = 1 UK person /year
Also, #HS2 will last much longer than 1.2 million electric vehicles.
Plus there's ecological impacts of lithium mining for EV batteries. Though building rail takes more concrete?Still :#RailNotRoad @Greens4HS2 /2
