Summary: | The amount of carbon dioxide (CO2) equivalent greenhouse gas emissions from the production of farmed seaweed. This includes every step of the process, including drying, which is a large portion of greenhouse gas emissions from seaweed production. | |
Method: | This value comes from a compilation of life cycle analysis studies. They used hierarchical Bayesian modeling to estimate both off-farm and on-farm stressors at the species level and used global production values to obtain means for taxonomic groups. The upper and lower bounds reported represent 50% of the width of the distribution of the parameter obtained from Bayesian modeling. | |
