It's been more than 25 years since food packaging added nutrition facts to help consumers make more nutritious choices when shopping for food. Now, there's a push to further influence consumer choices by displaying a product's carbon footprint data on its label.

Carbon footprint labeling is not a new idea. The Carbon Trust, a U.K. non-profit, launched one of the world's first carbon footprint certification programs and product carbon footprint labels in 2007. 

Some U.K. brands have been working with this independent organization since 2012 to assess the carbon emissions associated with their products. But carbon footprint labeling is still in an early stage and facing challenges to widespread adoption.

Jack Bobo, CEO of Futurity and an expert on food sustainability, explains the opportunities and challenges around implementing carbon footprint labeling, and whether the practice could change consumers' buying decisions.
