Reducing carbon emissions in aquaculture: Using Carbon Disclosures to identify unbalanced mitigation strategies
The production of Scottish Atlantic salmon (Salmo salar) involves a global supply chain with greenhouse gases (GHG) emitted at every step. With the UK government setting a net zero target by 2050, and the Scottish Government having committed to achieving net zero by 2045, the Scottish salmon aquacul...
