Food Waste & Climate Change: Learn How Food Waste Contributes to Global Warming
Every time we throw away uneaten food, we’re not just wasting nourishment—we're feeding a much bigger problem: climate change.

Food waste is one of the most overlooked contributors to global greenhouse gas emissions. According to the United Nations Food and Agriculture Organization (FAO), if food waste were a country, it would be the third-largest emitter of greenhouse gases—behind only China and the United States.

🌍 The Scope of the Problem
Globally, we waste about 1.3 billion tonnes of food every year, amounting to nearly one-third of all food produced. This waste occurs at every stage of the supply chain—from farms and factories to supermarkets and households.

But the environmental footprint of food waste extends far beyond the discarded produce.

🔥 How Food Waste Fuels Climate Change
When food is thrown away and ends up in landfills, it decomposes anaerobically—meaning it breaks down without oxygen. This process produces methane (CH₄), a greenhouse gas over 80 times more potent than carbon dioxide (CO₂) in the short term.

Key Environmental Impacts of Food Waste:
Methane Emissions: Rotting food in landfills emits massive amounts of methane.

Wasted Resources: All the water, energy, labor, and fuel used to grow, harvest, process, package, and transport that food are also wasted.

Deforestation & Land Use: Land cleared to produce uneaten food contributes to biodiversity loss and carbon release.

According to Project Drawdown, reducing food waste is the most impactful solution to reversing climate change, surpassing even solar power and electric vehicles in its potential benefits.

🍽️ The Role of Households and Businesses
Households are the largest contributors to food waste globally, particularly in urban areas.

Restaurants, supermarkets, and food producers also account for significant losses due to overproduction, mislabeling, and poor inventory management.
