CO2-Correct Food, Menus Minimize Greenhouse Gases
They then devised a weekly weight allowance for each food, which when followed, would reduce the use of greenhouse gases by about a third. Surprisingly, the list features foods such as chocolate, ice cream and red meat, but anyone wanting to reduce their carbon footprint must only eat them in relatively tiny quantities.
Some food groups, such as dairy products and meat, produce much bigger emissions of greenhouse gases such as carbon dioxide than others because of the way they are manufactured and brought to market. The production of fruit, vegetables and legumes is much less likely to produce such high emissions.
