Seafood CO2 Emissions Profiling Tool

Welcome to the Sea Fish Industry Authority's greenhouse gas emission profiling tool for seafood products from capture fisheries.

The purpose of this tool is to allow users to explore the carbon implications of sourcing and supplying seafood. This will provide a better understanding of the major contributors to the "carbon footprint" of seafood products. It also provides insight into the influence that some aspects of the seafood production chain have on carbon emissions. Major potential drivers of emissions that the tool addresses include direct fuel inputs to fishing, the form and scale of transport used and the amount of time products are held in cold storage. In this tool, we have also incorporated yield rates and the degree to which processing co-products (wastes) are utilized, and users may alter these variables.

In many instances, the tool will result in estimates of total greenhouse gas emissions associated with finished seafood products that accurately reflect real world conditions (over 90% accurate). In some cases, however, the emissions estimated by this tool will not adequately reflect real world conditions because aspects of the production chain are not accounted for. Examples of these could include emissions associated with bait acquisition and storage, emission intensive packaging, etc.

Please note that this tool is intended for information purposes only and is not intended to establish the carbon footprint of a seafood product. If you are looking for a definitive carbon footprint for your product, please contact the Carbon Trust for further guidance. It should also be noted that aquaculture-sourced products are not currently supported. We hope to add this if interests warrants.

We have attempted to build a tool that is robust, easy to use and flexible. Please try it out and let us know what you think. You can reach us at: carbon@seafish.co.uk.

Description of your supply chain
  Enter your data
Please provide a name for the chain you wish to model:
Fishing / Harvesting Method
Choose the fishing technique and target which most closely represents those used in your chain:
Yield of landed to live weight
Value between 1% and 100%:By yield of landed to live weight, we mean the ratio between the weight of the fish as landed and its live weight as caught. For example, if the fish is gutted, with the head left on, the yield would be around 60 to 70%, depending on the species.
% (e.g. after gutting at sea)
Yield of final processed form to landed weight
Value between 1% and 100%:By yield of final processed form to landed weight, we mean the ratio between the weight of processed product and the weight of the landed fish or shellfish. For example, if the fish upon landing is gutted with head on and your final product is a filet, the yield would be around 50 to 60%, depending on the species.
%
Are the co-products from processing used in any other product?By co-product, we mean all parts of the fish or shellfish not used in the main seafood product that results from processing (e. g. heads, skin, viscera, etc). Click “yes” if some or all co-products are used by yourself or others. If all co-products are treated as waste (i.e. landfilled or incinerated), click “no”. Yes
No

Pre-processing refrigeration
Was the fish frozen upon landing prior to be transported to processing? Yes
No
Total days refrigerated on fishing boat:We mean the time the fish spent in a refrigerate room on the fishing boat before being landed days
Duration of outbound refrigerated container transport:How many days did the fish spend in a refrigerated container on its way from where it was landed to where it was processed? days
Duration refrigerated storage pre processing:How many days did the fish spend in stationary cold storage prior to being processed? days
Post-processing refrigeration
Was the product frozen after processing? Yes
No
Duration refrigerated storage post processing:How many days did the seafood product spend in stationary cold storage after processing? days
Duration of inbound refrigerated container transport:How many days did the seafood product spend in a refrigerated container on its way from where it was processed to its final destination? days
Duration of refrigerated tractor trailer truck transport:How many days did the seafood product spend in a refrigerated tractor trailer unit on its way from where it was processed to its final destination? days
Duration of refrigerated delivery van transport:How many days did the seafood product spend in a refrigerated delivery van on its way from where it was processed to its final destination? days
Duration of final product refrigerated storage:How many days did the seafood product spend in stationary cold storage at or near its point of final consumption? days
