How will progress against the 20Megatonnes target be measured?
Annual emissions attributed to products sold in Carrefour stores by each participating supplier will be compared to the baseline year of 2019. The full methodology is available here.
What are Greenhouse Gases (GHGs)?
The Greenhouse Gases are Carbon Dioxide (CO2), Methane (CH4), Nitrous oxide (N2O), Hydrofluorocarbons (HFCs), Perfluorocarbons (PFCs), Sulfur hexachloride (SF6) and Nitrogen trifluoride (NF3). Different GHGs can have different effects on the Earth’s warming. They are reflected in the measure called Global Warming Potential (GWP). The GWP is a measure of how much energy the emissions of 1 ton of a gas will absorb over a given period (usually 100 years), relative to the emissions of 1 ton of carbon dioxide.
How are GHGs measured?
GHGs are usually expressed in carbon dioxide equivalent (e.g., kg CO2e), by converting amounts of other GHGs to the equivalent amount of CO2. This is done by multiplying the mass of GHGs by their global warming potential (GWP).
