In early 2020, the SaladStop! Sustainability team completed an assessment to estimate the carbon footprint of all salad bar offerings in Singapore. SaladStop!'s carbon information reflects the total estimated carbon dioxide equivalent (CO₂e) associated with an ingredient. A CO₂e is a unit of measurement that describes emissions from all different greenhouse gases (GHG) as a single number. This is done by measuring emissions from various GHG based on their global warming potential. Then converting the amounts of other GHG to the equivalent amount of carbon dioxide with the same warming.
The emissions from ingredients vary as different ingredients require more energy for growth and production. Plant-based produce typically has a lower carbon footprint than animal-based products. The distance the ingredient has to travel and the method of travel also influence emissions at the transportation stage.
