- impose a maximum limit on size, weight and fuel consumption of cars, ban SUVs and pickup trucks (and no, a tax won't work because the rich will simply buy their "freedom"). Exceptions only upon proof of need (e.g. commercial or farming usage).
- ban all inner-country flights of less than 2 hours duration (this one is not that applicable to the US but more towards Europe)
- improve passenger high speed rail networks in accessibility, affordability and speed
- improve (or, in some places, create) usable public transport systems to reduce the need for cars
- entirely ban naval cruise ships unless fueled by renewable fuel
- construct immense amounts of solar and wind electricity generation, invest into storage mechanisms and power-to-gas
- impose bans or limitations on concrete for construction (8% of global CO2 emissions result out of the manufacturing of concrete!)
- ban "fast fashion", impose durability requirements on clothing
- force all manufacturers to provide spare parts, 3D designs and tooling needed for repairs, no matter what kind of thing
- impose per-capita meat consumption quotas. Yes, this is communism-style, but we cannot sustainably continue with mass animal farming at the scale we are at.
