Potatoes are the sustainable carbohydrate, according to the results of new research from Cranfield University, in which scientists compared the total greenhouse gas emissions (GHGE) and water usage for potatoes against rival carbohydrates, rice and pasta.

The comparative study was commissioned by industry group the Potato Council, which is seeking to boost the profile and environmental credentials of the humble spud. The Council said, "Environmental concerns when it comes to food production are major issues for both the farming and manufacturing industry."

The Potato Council plans to present the research findings to levy payers at a meeting in Warwickshire next month. Caroline Evans, Potato Council's head of marketing and corporate affairs, said, "The study builds on our previous research work to show that GB potatoes are healthy. The industry has made significant advances in sustainable production methods and it is important that we focus on generating maximum and consistent exposure for these messages amongst Government and agencies, as well as consumers."
