Livestock & fisheries account for 31% of food emissions. Livestock – animals raised for meat, dairy, eggs and seafood production – contribute to emissions in several ways. Ruminant livestock – mainly cattle – for example, produce methane through their digestive processes (in a process known as ‘enteric fermentation’).
Full Answer
How does food loss and waste affect the environment?
Food loss and waste also exacerbates the climate change crisis with its significant greenhouse gas (GHG) footprint. Production, transportation, and handling of food generate significant Carbon Dioxide (CO2) emissions and when food ends up in landfills, it generates methane, an even more potent greenhouse gas.

How is food waste a problem?
Food waste is a problem because it costs Americans billions of dollars in lost revenue, puts a tax on natural and human resources, and harms the environment by contributing to global warming and climate change when food waste is added to landfills and produces the greenhouse gas methane.
Why is food waste important?
Wholesome food that is currently wasted could help feed families in need. Safe and wholesome food that is currently thrown away could help feed hungry people and reduce food insecurity today. Each year, Feeding America and its network of food banks rescues around 3.6 billion pounds of food.
How does food waste affect biodiversity and the environment?
This is a hidden but real cost of food waste: it decimates biodiversity in a number of ways: Deforestation, especially in tropical areas, destroys natural flora and fauna (sometimes to the point of extinction), in the name of creating more land for food production.
How much does food waste contribute to global warming?
about 8%Global food loss and waste generate annually 4.4 GtCO2 eq, or about 8% of total anthropogenic GHG emissions (5). This means that the contribution of food wastage emissions to global warming is almost equivalent (87%) to global road transport emissions (6).
How does food waste affect poverty?
For millions of people in low-income countries, this food waste happens at harvest time. Poor storage leads to pest infestations or mold that ruin crops before they can be eaten. Along with chronic poverty, conflict and natural disasters, food waste is one of the root causes of hunger worldwide.
Why did the FDA relax labeling requirements for packaged foods?
Food and Drug Administration also relaxed labeling requirements for packaged foods as a way to allow restaurants and other foodservice operators a way to sell off their food stocks when their businesses were shuttered (FDA, 2020). Concluding Thoughts. Covid-19 has disrupted the entire food supply chain.
What causes food waste?
At the farm level, food waste is often the result of market factors (for example, price volatility , high labor costs, or lack of labor availability); a product not meeting aesthetic standards for a buyer (most common for grocery retail and foodservice buyers); or damage from weather and pests (Minor et al., 2020).
What are the disruptions in the supply chain?
The disruptions have increased food waste for some supply chain actor s, particularly producers who are strongly tied to the foodservice sector and foodservice operators who were forced to abruptly close. Other supply chain actors, including processors and grocery retailers, likely have not experienced such increases in food waste.
What is the supply chain for food?
The supply chain for food is complex and highly specialized. Producers of perishable products like meat, milk, and fruits and vegetables often grow their crops specifically for either the grocery retail or the foodservice (e.g., restaurants, schools, hospitals, hotels, stadiums, movie theaters) sectors.
What are some examples of dairy industry?
Example 1: Milk – When major buyers of dairy across the country – for example, schools and coffee shops – temporarily closed, the dairy industry suddenly had a surplus of milk on its hands. Cows couldn’t stop being milked, so farmers who couldn’t find alternative buyers dumped huge quantities of their excess milk.

How much of the world's calories are thrown away?
Around one-quarter of the calories the world produces are thrown away; they’re spoiled or spilled in supply chains; or are wasted by retailers, restaurants and consumers. 44 To produce this food we need land, water, energy, and fertilizer inputs. It all comes at an environmental cost.
What is the water footprint of food?
The water footprint of food products gives a useful indicator of their environmental impact. But freshwater scarcity varies across the world: some regions have abundant water resources (meaning agricultural water demands have little impact) whilst others experience severe water stress.#N#We can also look at water footprints in terms of scarcity-weighted freshwater use. Scarcity-weighted water use represents freshwater use weighted by local water scarcity.
Does transportation add to carbon?
For food that is transported by sea, transportation doesn’t actually add much to the carbon footprint. Since most of our food is transported by sea, transport emissions only account for 6% of the carbon footprint of food, on average. 41.
Producer-Level Food Waste
Processor-Level Food Waste
- Processors are often one of the most efficient nodes in the food supply chain when it comes to food waste. Any waste or trimmings at the processor-level are typically re-purposed for other products (for example, animal feed or bioenergy). Covid-19 has undoubtedly impacted food processing facilities and most notably, meat processors. Many meat packi...
Foodservice-Level Food Waste
- The foodservice sector generates waste in both its back-of-house (kitchen waste) and front-of-house (plate waste) operations and can exert more control over back-of-house waste with careful planning and inventory management. However, no amount of planning could prepare foodservice operations for the sudden shuttering of businesses during Covid-19. Many states early on in the …
Retail-Level Food Waste
- At the retail-level, food waste in grocery stores is often attributed to: over-stocking of perishable products like fruits and vegetables to ensure consumers are satisfied with the product assortment and products reaching or nearing their stated or actual shelf life (Gunders, 2012). When Covid-19 hit the U.S., the media consistently reported on empty shelves at grocery stores. First, there wer…
Household-Level Food Waste
- Before Covid-19, households were identified as the largest source of food waste along the supply chain in developed countries like the U.S. (Gunders, 2012; Buzby, Wells, and Hyman, 2014). Several factors contribute to household food waste, including poor planning and inventory management, confusion surrounding date labels, and bulk purchasing (Gunders, 2012). Stockpili…
Efforts to Mitigate Food Waste During Covid-19
- Covid-19 has significantly impacted food waste along the supply chain; however, supply chain actors and policymakers have worked to identify “pandemic pivots” to mitigate food waste. At the farm-level, many farmers donated or sold their products to food banks when possible (Karidis, 2020; Evich, 2020). As food banks are seeing increased use across the country right now, this re…
