Carbon-Footprint-Assessment

Carbon Footprint Assessment

As a way to develop superior techniques that will better conserve the atmosphere ,  Dole Food Company, Inc. requested that Soil & More International B.V. conduct a study and calculate a comprehensive CO2e (carbon dioxide equivalent) footprint of its bananas.  Click here to access the full report.

The term “carbon footprint” represents the sum of all greenhouse gas emissions caused by a product’s life cycle. The system boundaries of the footprint are defined below. “Greenhouse gas emissions” stands for compressible fluids that have been assigned a coefficient for their global warming potential by the Intergovernmental Panel on Climate Change (IPCC). This study includes different greenhouse gases that are emitted during different stages of a product life cycle: carbon dioxide (CO2), methane (CH4), and nitrous oxide (N2O), as well as chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs). Because the Global Warming Potential (GWP) of methane and nitrous oxide is higher than that of carbon dioxide’s, these two gases are stronger greenhouse gases. In the following footprint, all identified greenhouse gases are converted into CO2e by multiplying them with the GWP value.

Table 1: Greenhouse gasses included in this study with their GWP value

Type of Gas Chemical Formula Global Warming Potential (GWP)
Carbon dioxide CO2 1
Methane CH4 25
Nitrous oxide N2O 298
Hydrochlorofluorocarbons HCFCs 124 – 14,800[1]
Chlorofluorocarbons CFCs 4,750 – 14,400
