Ggggrreeaat for the environment? Kelloggs vs General Mills

In the global effort to limit climate change and reduce greenhouse gas emissions (GHGs), the energy and transportation sectors are the most obvious targets, but perhaps not the biggest. Consider the food business. Agriculture alone produces up to 35% of the world’s greenhouse gas emissions (and uses 70% of the water).

By some estimates, humanity may need to produce as much food in the next 40 years as it did in the last 8,000. And that can’t happen if we don’t get the carbon and water footprint of agriculture under control. Because of this, food giants like Kellogg and General Mills are getting serious about emissions.

Deciding which food manufacturing company to support can be a tough decision, so we’ve tried to break down two of the more known chains and what your purchase will support.

Ethically partners with CSRHub as a primary data source, which in turn, aggregates over 700 data sources, compiling them into simple, easy to digest grades. 

General Mill’s score is a few points above Kellogg’s. The biggest differences are seen in the Environment and Social Responsibility categories. General Mills will cut absolute GHGs by 28% by 2025 “across the entire value chain.” By 2050 it will slash emissions up to 72%, with the exact number TBD, but at a pace that will keep them “in line with scientific consensus.” Kellogg’s 2050 target is to cut its own and supplier emissions by 65% and 50% respectively. 

As consumers of the food products these companies manufacture, we must continue to hold these entities responsible for how they treat their employees and how their productions affect our environment.  If you’re a Kellogg’s advocate and want to see more evidence that they’re committed to these areas, email our CEO at and let us know. We’d love to hear from you.
