”Plastic film, 2020” has a climate footprint of 3.0 kg CO₂e/kg. This value is updated when there are changes in the way the product is made, and when we update our calculations to match the latest climate science.
|Climate Footprint History|
CarbonCloud guarantees that this number can be compared to all other food products with a common yardstick, on our growing community of climate footprints.
Agriculture leads to greenhouse gas emissions through biological soil organic processes, manure management, enteric fermentation and carbon leakage from organic soils. There are also emissions from fossil fuel use in machinery and the production of inputs such as fertilizers and pesticides. Finally there is the consumption of fossil fuels and electricity on farm for drying and other processes. By far the most important greenhouse gases from agriculture are nitrous oxide (N2O), methane (CH4) and carbon dioxide (CO2).
Most food products have gone through some sort of processing. It could be cleaning, heating, cooling, drying, mixing, sterilization, fermentation or many other things. These processes usually consume natural gas, biogas, oil and/or electricity. Some processing also requires the use of chemicals.
Transporting goods on water is usually very climate efficient per km, since container ships carry huge loads at slow speeds with little fuel consumption. Over land fossil-powered trucks are commonly used for longer distances, which increases the climate footprint. Trains, where possible, are similar to container ships in that they move large amounts of goods at low climate burdens, especially if electrically powered. Airplanes are used for certain fresh foods that are consumed far away from where they are produced. This is the most energy demanding way of transport per km.
In warehouses energy is consumed mainly for lighting, space heating, refrigeration and ventilation. In refrigerated warehouses leakage of refrigerants contribute to climate change since these are powerful greenhouse gases.
Energy and raw resources used when packaging products along the production chain.
An ingredient that uses carbon material that has been extracted from the ground. Includes oil, coal and similar.
All activities that are not attributable to any other category. This includes production of ingredients where the “agriculture” and “refinement” steps are not distinguishable.
