how can we reduce food waste

Reducing food waste starts with small daily habits: plan what you buy, store it properly, use leftovers creatively, and donate or compost what you can instead of throwing it away. These steps save money, cut emissions, and help ease pressure on global food systems.

Why food waste matters

• Around 40% of food produced globally is lost or wasted between farm and fork, even though that food could feed all food-insecure people worldwide.

• Food waste also means wasted water, energy, land, and about 8–10% of global greenhouse gas emissions.

Smart shopping and planning

• Make a weekly meal plan and shopping list so you only buy what you can actually use.

• Avoid bulk buys for perishable items, and don’t shop when hungry, which pushes people to overbuy.

Storing and using food better

• Check your fridge and pantry often, using a “first in, first out” rule so older items are eaten first.

• Learn basic storage tricks (like keeping fridges between 1–5°C and using the freezer for extra portions and leftovers).

Cooking, leftovers, and compost

• Plan “leftover nights,” make soups, stir-fries, or casseroles from odds and ends instead of binning them.

• Compost unavoidable scraps like peels and coffee grounds to keep them out of landfills and feed soil.

Sharing, donating, and system change

• Choose “ugly” but perfectly edible fruits and vegetables that often get left behind in stores.

• Support or join local food-rescue programs and donate safe surplus food to food banks and pantries where possible.

Every time a meal is planned, a list is written, or leftovers are rescued, food moves from “future trash” to “real nourishment” for people and the planet.

TL;DR: To reduce food waste, plan your meals, buy only what you need, store food correctly, eat leftovers, donate what’s still good, and compost the rest.
