Learning from product carbon footprinting
3. Choosing between similar products can lower your carbon footprint:
• Fresh pasta products have a higher carbon footprint (typically 10% to 20% higher) than dried pasta products (due to chilling in store and during transit).
• Washing up using a full dishwasher with dishwasher tablets has a lower carbon footprint than washing up by hand using washing up liquid (for smaller loads you’re better off washing by hand though).
1. Geography makes a difference:
• Producing cucumbers seasonally in Spainwithout heating results in a significantly lower carbon footprint than producing cucumbers in UK or Dutch heated greenhouses.
• A bunch of red roses from Kenya has a significantly lower carbon
footprint then one from Holland (due to the increased quantity of fuel and electricity consumed in the Dutch operation)
2. So does the way a product is used:
• The energy required to cook baked potatoes makes up about 70% of their footprint. For boiled potatoes, boiling potatoes with the saucepan lid on, rather than off, saves up to 80% of the energy used to cook potatoes.
• The majority of the carbon footprint of a pair of jeanscomes from the energy required to wash and dry them.
