Work on a national, government-controlled label to highlight food products' climate footprint is underway in Denmark, and some seafood executives fear what story it might tell.

The label, which would be the first climate label regulated by a government, will require food manufacturers and retailers to specify the total amount of carbon emissions that production of the product has generated.

A panel created by Denmark Minister for Food, Agriculture and Fisheries Rasmus Prehn is scheduled to present a proposal for the new label by the end of the year.
