Life Cycle Considerations for Improving Sustainability Assessments in Seafood Awareness Campaigns

It is widely accepted that improving the sustainability of seafood production requires efforts to reverse declines in global fisheries due to overfishing and to reduce the impacts to host ecosystems from fishing and aquaculture production technologies. Reflective of on-going dialogue amongst participants in an international research project applying Life Cycle Assessment to better understand and manage global salmon production systems, we argue here that such efforts must also address the wider range of biophysical, ecological, and socioeconomic impacts stemming from the material and energetic throughput associated with these industries. This is of particular relevance given the interconnectivity of global environmental change, ocean health, and the viability of seafood production in both fisheries and aquaculture. Although the growing popularity of numerous ecolabeling, certification, and consumer education programs may be making headway in influencing Western consumer perceptions of the relative sustainability of alternative seafood products, we also posit that the efficacy of these initiatives in furthering sustainability objectives is compromised by the use of incomplete criteria. An emerging body of Life Cycle Assessment research of fisheries and aquaculture provides valuable insights into the biophysical dimensions of environmental performance in alternative seafood production and consumption systems, and should be used to inform a more holistic approach to labeling, certifying, and educating for sustainability in seafood production. More research, however, must be undertaken to develop novel techniques for incorporating other critical dimensions, in particular, socioeconomic considerations, into our sustainability decision-making.     

Carbon labelling of grocery products: public perceptions and potential emissions reductions

Public perceptions of a UK carbon labelling trial were assessed via three focus groups. The public found it very difficult to make sense of labelled emissions values without additional information. There was also little evidence of a willingness to use labels for product selection. There is a strong case for using carbon reduction labels to indicate a programme of on-going emissions reductions, rather than expecting consumers to incentivise emissions reductions by actively choosing the lower carbon variant of two or more products. The normalisation issues and emissions reduction potential of carbon labelling are discussed.
