  5. Measuring and Mitigating GHGs: Salmon

There are millions of farms globally, each using a unique set of practices to cultivate their products in the local climate and soil. For any commodity, there are many thousands of different production systems and many different sources of greenhouse gases. Relative GHG emissions of producing the same product may differ drastically depending on how and where it is grown. To fully understand how to mitigate emissions and on which farms to focus mitigation efforts, we need a better grasp of variations and gaps in data. Salmon emissions are dominated by the emissions embedded in the feed salmon eat, but on-farm rearing and transport also add to the overall footprint.
