I am wondering about a specific carbon footprint comparison (i.e. total global warming potential per litre) between soy milk and cow's milk.
This would of course depend on where and how they are produced, but I'd like to know if people have sources that could potentially be gathered (or an article that already did a meta-analysis of some sort!) to have a general idea of the order of magnitude of the difference.
