What is CO₂e?

You’ve probably heard of carbon dioxide (CO₂), perhaps from your chemistry class in school. But you might not be so familiar with CO₂e. Carbon dioxide equivalents (CO₂e) are a measure used to indicate the climate impact of a food product or meal in the Floop app.

What is the difference between CO₂ and CO₂e?


CO₂e means carbon dioxide equivalents. You'll see we use CO₂e a lot in the Floop app.


CO₂ only refers to one gas: carbon dioxide. However, CO₂e refers to several different greenhouse gases, including; methane, nitrous oxide and fluorinated gases (F-gases).


These greenhouse gases all contribute to global warming, which is responsible for climate change.


Carbon dioxide accounts for most greenhouse gases, at somewhere around 75%. This high value helps explain why it tends to take the limelight when talking about climate change.


Methane (CH₄) accounts for 17%, Nitrous Oxide (N₂O) for 6%, and F-Gases account for the remaining 2% of greenhouse gases.  


Why does the Floop app use CO₂e?


The Life Cycle Assessment tool used for Floop’s carbon footprint calculation considers all greenhouses gases produced at each stage of a food product's lifecycle. 


The Floop app calculates the total greenhouse gases from all ingredients in your meal to provide you with a single carbon footprint value (CO₂e) for your meal.


This value helps you see which of your meals and food choices produce less CO₂e and thus have a lower impact on the climate.
