Reducing your food waste – many consumers don’t realise that our collective food waste is a major contributor (around 10%) to global greenhouse gas emissions. So, cutting down our food waste is one of the most effective ways that consumers can lead more climate friendly lives. This means planning your meals, shopping only for what you need, storing food correctly, freezing surplus food whenever possible, giving away excess food and making sure you use perishable food items such as dairy before their expiry dates.
