- Households of 1 or 2 people should not buy food in bulk because it may be wasted and food producers should offer cost-effective smaller packages.
- Cut out or reduce foods that are high in calories but low in nutritional value. This could result in a 29% reduction in emissions and would also have a positive impact on health.
- Buy less sweet bakery foods and ready-made, processed foods. Though individually, these foods have a low carbon emission, the large amount of these items that are purchased adds up to significant emissions.
These finding were the result of a study (Large-Scale Microanalysis of U.S. Household Food Carbon Footprints and Reduction Potentials | Environmental Science & Technology (acs.org) conducted on 57,000 American households.
