Anna Arenillas | It is widely known that planetary boundaries (Stockholm Resilience Centre, 2021) are being transgressed by human activity and that the food value chain is a significant contributor to such transgressions. Climate change – fostered by greenhouse gas emissions, which increase the global average temperature – is one of them. As a matter of fact, food production accounts for 26% of global greenhouse gas emissions. On top of that, not all types of food contribute to the carbon footprint equally. In fact, beef emits 49.89 kgCO2eq per 100 grams of protein throughout all of its value chain, particularly at the farming stage.
