The United States Agency for International Development's (USAID) global hunger and food security initiative, the Feed the Future project, is addressing food loss and waste. By addressing food loss and waste, greenhouse gas emission mitigation is also addressed. By only focusing on dairy systems of 20 value chains in 12 countries, food loss and ...
The authors found that agriculture and waste—including landfills and wastewater management—were responsible for releasing almost double the methane emissions into the atmosphere as fossil fuel ...
The carbon footprint explained Comparison of the carbon footprint of protein-rich foods [1]. A formal definition of carbon footprint is as follows: "A measure of the total amount of carbon dioxide (CO 2) and methane (CH 4) emissions of a defined population, system or activity, considering all relevant sources, sinks and storage within the spatial and temporal boundary of the population, system ...
Food recovered by food waste critic Robin Greenfield in Madison, Wisconsin, from two days of recovery from dumpsters [1]. Food loss and waste is food that is not eaten. The causes of food waste or loss are numerous and occur throughout the food system, during production, processing, distribution, retail and food service sales, and consumption.
That matters because food waste contributes over half the planet-warming methane emissions that come from landfills, according to the Environmental Protection Agency.
On the demand side, limiting food waste is an effective way to reduce food emissions. Changes to a diet less reliant on animal products such as plant-based diets are also effective. [127]: XXV This could include milk substitutes and meat alternatives. Several methods are also under investigation to reduce the greenhouse gas emissions from ...
"Local food" campaigns may be motivated by protectionism rather than genuine environmentalism. [46] When looking at total greenhouse gases (not just carbon dioxide), 83% of emissions come from the actual production of the food because of the methane released by livestock and the nitrous oxide due to fertilizer. [45]
Furthermore, the carbon dioxide emissions from food waste that decomposes in landfills, etc., amount to 2.5 kilograms of carbon dioxide per kilogram of food and also produce methane, a greenhouse gas with 25 times the warming potential of carbon dioxide. [105] Food waste also represents a loss of the energy to transport foods from producers to ...
