Food Carbon Footprint: Challenges and Opportunities

Abstract

“Carbon Footprint” (CF) term has become popular over the last decade due to the high rate of climate change. Food related GHG emissions is a main cause of climate change, which needs to be reduced. Following the raising awareness of the food impact on carbon footprint of consumers, a number of recent studies have analysed how the citizen contribute to the reduction of emission of carbon ‘footprint’. This paper identifies the challenges and opportunities in being able to evaluate carbon ‘footprint’ (named CF) of food choices and we reviewed some current approaches of CF calculator tools at dish ingredient level, or recipe level, and finally, applications that help to reduce Carbon Footprint of foods.
