That factoid always hides the real issue. The biggest reason that that factoid is true is that the 100 biggest companies includes a large amount of the fossil fuel industry, and that that industry produces most emissions in the world. A company like Saudi Aramco produce 4% of global emissions.

We need to reduce our dependency on fossil fuels.

For full clarity, it's also not the 100 biggest corporations that produce most emissions, but the 100 biggest companies. A massive amount of the global emissions are done by state-owned companies.

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)

Don't corporations just serve their patrons?

The smaller ones are most likely less efficient (which blocked their growth). So it'd be a game of whack-a-mole where every hit makes everything worse...
