Dietary changes are already underway. Companies such as Hilton, IKEA and Max Burgers have signed a “Cool Food Pledge” to reduce the food-related emissions they provide by 2030 by 25% compared to 2015, an ambitious goal to keep global warming below 1.5 degrees Celsius. The results show that even if fossil fuel emissions were immediately halted, some level of food conversion will be needed to keep global warming below 1.5 degrees Celsius above pre-industrial levels, which is the most optimistic goal of the Paris agreement. This change in diet will not happen without action by businesses and governments, which will need to show leadership and create an environment conducive to change, supporting consumers, businesses and food producers and encouraging changes in their behaviour and practices. According to a new study, the world cannot meet its most ambitious climate goals without eating less meat. This regime change … would be relatively easy to implement, as it only affects one type of food. In addition, some high-consumption countries have already reduced per capita beef consumption from historic highs, indicating that further changes are possible. Urban dwellers generally consume meat and milk higher than the population of the great land.
Hong Kong – where I come from – is an infamous case; About 40% of our daily caloric intake comes from meat, egg and dairy products. Adopting a diet of “most plants” would not only be a doctor`s recommendation to their patients, but also one of the deepest pathways to a sustainable planet with a stable climate. The lessons of this summary of science are clear: the great potential for reduction comes not only from the vegan or vegetarian diet, but also from dietary changes that replace ruminant meat (most often cattle) with meat from monogastric animals (i.e. non-ruminants, most often chickens and pigs). But how much do diets need to change to meet climate targets? An international team of 36 researchers and I have tried to answer this question in the Eat Lancet Committee for Healthy Eating Sustainable Food Systems. We have developed recommendations for healthy, healthy and nutritionally balanced health nutrition, which, combined with other changes in the food system, achieves the climate food goal and other environmental goals, including land and water use and fertilizer use.
