The Math of the AI Environmental Impact
We recently had post here that posited that AI was a severe environmental impact, and there was no math, which I thought was a shame and not really becoming for women in tech. We should work from a position of good data.
Here's the best breakdown I can do right now.
Training models were estimated to cost about 25-30 million tons of carbon in 2025. Compare that to the video game industry, which burned through more than 80 million tons of carbon in 2025. (80 million tons is just what the big studios admitted to.)
Usage of AI varies. Basic models cost about 1/3 of a gram of carbon per query. Heavier hitting AI models cost about 3/4 of gram. We can assume that some models cost more like 1.5 grams per query. Assuming 250 heavy hitting prompts in a day, which would be exceeding overkill usage, that's just about 1/3 of a kilogram per work day, or assuming about 250 workdays in a year, less that 100 kilos of carbon a year from that worker. (Less than 200 pounds.)
But I said heavy hitting, someone like me who is using AI for documentation is hitting well less than half that. We're looking at about 12 kilos or 26 pounds of carbon each year.
Anything that adds to the footprint isn't great, but that's insubstantial compared to other things that many of us do with very little consideration. The average American goes through 14-16 TONS of carbon a year. AI usage, in the office setting, at the highest imaginable use is about 1% of their total impact on the planet each year.
As a point of comparison, the average Disney vacation is just over 2 tons of carbon, spent in a matter of days. Another and possibly more salient point: the average "Korean" skincare routine is about 20 kilos, or 40 pounds of carbon a year. That doesn't include makeup or haircare. Add in haircare and makeup, and you've got another 50-100 kilos of carbon being produced. Food waste? Even if you throw out just about one fridge worth of food in a year, that's 80-100 kilos of carbon being straight up wasted.
AI is adding to a burdened environment, but it's far from being a major aggressor in the climate battle.
If you are genuinely concerned about the carbon impact of the AI you are being required to use at work, I'd suggest these actions:
- Ask for hybrid days to offset the carbon. The average commute puts 6-10 kilos into the atmosphere every day.
- Ask for casual Fridays when hair and makeup isn't expected, which reduces carbon needed to be 'presentable' on those days.
- Ask them to turn up the thermostat in the summer and down in the winter and tell people to dress for it.
- When upgrades or renovations are being discussed, ask for sustainable choices and energy star appliances.
