There's a difference between a market and a significant market.

Cost-to-benefit analysis, sure. But you still need a realistic comparison of the costs side of the equation to do that.

People were whining about the energy costs of regular data centers long before AI came along.

That invites a lot of questions like is it lower carbon to have a zoom call than fly out for a meeting? Do the travel emissions of an imported tomato offset the heating emissions for a local out-of-season hothouse tomato? If I'm going to make one personal sacrifice, is it more effective to give up red meat, bike to work, or make my next holiday less far away?

Intentionally ignoring evidence is just dumb; decisions made purely on vibes are often going to be wrong.

So your alternative is what? Just say a tonne is a tonne?

It's adequate for the purpose at hand.

Lots and lots of math and analysis.

My understanding is it is fairly well settled on a chemical & lifespan basis. I am not sure of what impact initial altitude has.

Anaerobic bacteria produce methane. When oxygen is present, the aerobic pathway outcompetes anaerobic because more energy is available, producing CO2 instead.

GHG are usually measured in tonnes of CO2 equivalent (GWP) where methane is about 80x as much warming as the same mass of CO2 over a 20 year period, or about 25x as much warming over a 100 year period.

This is also what's going on in the steady replacement of various refrigerants with lower-GWP alternatives.

40% thrown away does not necessarily imply all others are better.

Normally imperfect produce goes to processing plants (juice, cans, pies etc.) but I'm not sure if there's any significant market for banana chunks/puree.

But all of those are net emissions?

Desire-to-die is potentially a reasonable way to describe 15 hours in an economy airline seat, or stuck in/as traffic.

I.e. so fed up with this that you'd rather be dead.

I feel like the axes need better labeling. Putting the labels on the negative is confusing.

A lot of the emissions from food are not things that are already in the carbon cycle.

• Deforestation to turn forest into farmland.

• Fossil fuels for equipment and to manufacture fertiliser.

• Methane from animals is significantly more potent than if that same carbon was released as CO2.

Electric buses have a battery from a probably reputable supplier, with a decent BMS.

Escooters often come from AliExpress.

There is a difference.

“Spotify already pays nearly 70% of every dollar it generates from music to the record labels and publishers

Sounds like the issue might be with the record labels...
