A two week experiment by BBC Future has found some thought-provoking ways to lower emissions from our food, writes Veganuary : “What is clear from our experiment (and more importantly, from rigorous scientific research) is that on average a plant-based diet has significantly fewer emissions.” It stated that the tweaks to our diets that would result in the greatest fall in emissions were: – Reducing animal products – eating fewer of them, or replacing with a plant-based alternative – Focusing on what you eat rather than food miles – Cooking efficiently, and saving ovens for special occasions rather than everyday use – Batch cooking to prepare food using a fraction of the energy – Avoiding food waste, through careful planning and creative cooking You can read about the experiment in full here .
