The BBC has published an online carbon emissions calculator tool which can be used by anyone to calculate the climate footprint of different common food groups, including potatoes.
When one activates the calculator to determine the footprint of potatoes as a food source, it becomes clear that potatoes are and remain one of the most environmentally friendly, low carbon additions to anyone’s evening meal.
For example: If you were to input that you have two small potatoes per serving 3-5 times per week with a meal, the calculator indicates that your consumption of potatoes is contributing 9kg to your annual greenhouse gas emissions. That’s the equivalent of driving a regular petrol car 25 miles (40km), or the same as heating the average UK home for 1.5 days. The calculator also indicates that potatoes contribute less to greenhouse gases than rice (most), pasta, oatmeal, and bread.
