I argue it's impossible to measure the total environmental impact of anything, and it's a waste of time to even try. Let's break this down. There is water used at inference time and training time. The humans working on the project consume water. The building in which they did the project uses water. The whole supply chain for the computers? Good luck measuring the water usage in there This may seem pedantic, but I promise there is a point to this. Measuring environmental impact is like trying to understand a neural network. If you want to discourage water usage, the only way is to tax the marginal water used at any step in the supply chain. You don't need to know the total water usage for the last step of the supply chain, in this case, an LLM
