A low-carbon diet is a way of eating that results in fewer emissions of carbon dioxide, which is a harmful kind of pollution. When you eat food, it takes energy to grow, process, package, and get the food to your plate. This energy usually comes from burning fossil fuels, like coal and natural gas, which create carbon dioxide when burned. Eating a low-carbon diet means eating food that takes less energy to produce, and therefore creates fewer emissions. It generally involves eating more plant-based foods, like vegetables and fruits, and avoiding processed and/or imported foods. It also means reducing waste by only buying and eating what you need.
