Amidst the debate on salmon aquaculture in BC, science-backed data showing the sustainability of BC farmed salmon is sometimes ignored or forgotten. We reprint results of a 2016 study
Salmon raised in the ocean have the lowest overall cost to the environment, says a research on consumers’ most common protein choices. The research, prepared for the British Columbia Salmon Farmers Association (BCSFA) by Ottawa-based RIAS Inc, looked at the production of salmon versus other major proteins in terms of energy use, greenhouse gas emissions, eutrophication potential, water use and land use.
Results indicate that BC farm-raised salmon is 24-percent less costly to the environment than chicken, while beef has a cost that’s 500-percent greater than salmon raised in an ocean environment.
The study used a life-cycle analysis (LCA), defined by the United Nations Environmental Programme as “a tool for the systematic evaluation of the environmental aspects of a product or service system through all stages of its life cycle.”
“Health professionals agree that salmon is by far the most healthy protein choice for people to eat, this study shows it’s also the most healthy protein for our planet,” said Jeremy Dunn, who was the executive director of the BC Salmon Farmers Association when the study came out. “With the world population estimated by the United Nations to grow by over 2 billion by 2050, governments must consider the full environmental costs of the food we grow and eat.”
