An inside look at the footprint of salmon

The document outlines a four-step process for calculating the carbon footprint of salmon, covering feed production, farming, processing and packaging, and transportation. It details how data on waste, electricity, fuel, and packaging are converted into CO2 equivalents to identify mitigation opportunities and track progress toward the "The Salmon of 2030" benchmark.

• The carbon footprint calculator for salmon aquaculture focuses on four critical phases: feed production, salmon farming, processing & packaging, and transportation to distribution centers.
• To calculate emissions during the processing and packaging phase, the tool gathers specific data on live-weight waste, electricity consumption, fuel usage, and the quantity and type of packaging used.
• The calculator applies different emission factors based on the source or method; for example, landfilling organic material generates approximately 0.7 kgCO2e per kg, whereas composting generates about 0.01 kgCO2e, and coal-based electricity produces about 1 kgCO2e/kWh compared to 0.02 kgCO2e/kWh for hydropower.
• The tool is designed to allow GSI member companies to compare their values, share effective reduction strategies, and track progress toward a benchmark called "The Salmon of 2030".
