That’s basically a different way of measuring the same thing. These corporations don’t just exist in a bubble, many of them are going to be behind the food production either directly or indirectly (e.g. energy companies providing fuel for machinery).
Food is responsible for about a quarter of greenhouse gas emissions[1]. I agree that it’s not realistic to assume this will be solved individually, more pressure needs to be put on these large corporations from governments, but the quickest way you or I can make our own (individually small, collectively large) impact is by cutting out meat from our diet (specifically beef[2]). We are end-consumers of those 100 largest corporations one way or another.
(Not a vegetarian/vegan btw. I’m not trying to shame, I’m certainly not perfect! I just wanted to share the info that it’s not someone else’s problem. We’re all in this together)
