@clh3 Hi Calvin, I saw that you are a food literacy enthusiast.
Have you seen that some companies put the climate footprint on their food. A 90 gram burger for example has 2.2 kg CO2e and a liter of oat drink has 0.31 kg.
This startup does labelling https://www.carboncloud.com/
The burger company uses another external company to calculate the values.
Their English site doesn't have a menu, but it easy to guess your way to the numbers in the Swedish "meny"
@JohanEmpa I see climate footprint labels on packaging or menus occasionally. I think the labels are most effective when the consumer is open to trying a new food or two.
@clh3 yes, that sounds likely
