Switching from an omnivorous to a vegan diet can reduce daily greenhouse gas emissions by 46%, while also lowering land and water use and maintaining nutritional balance.
Vegan diet can halve your carbon footprint, study finds
Only around 1.1% of the world's population is vegan, but this percentage is growing. For example, in Germany the number of vegans approximately doubled between 2016 and 2020 to 2% of the population, while a 2.4-fold increase between 2023 and 2025 to 4.7% of the population has been reported in the UK.
