Large scale reduction in meat consumption
The National Week Without Meat aims to inspire a large proportion of the Dutch population to eat less meat. What is the reduction in environmental impact if one person eats no meat on one day of the week for a whole year? The reduction in climate change impact is 98.7 kg CO2
equivalents, or a journey in an average car of more than 560 kilometres. The reduction in land use impact is more than 66 square metres and the reduction in water use is almost 970 litres. Of course, these savings would be lower if the meat is replaced with products such as eggs, tofu, meat substitutes or nuts.
It should be noted that if a very large group of consumers replace meat in their diet with alternative products, this may result in changes to the life cycles of these products and the way nutrients are consumed. More extensive calculations would then be needed to determine the final environmental impact, taking account of various efficiency and substitution effects.
