Article from Netherlands Environmental Assessment AgencyReducing global meat consumption would reduce greenhouse gas emissions and cut the costs of climate policy substantially. This is the result of a PBL study published in Climatic Change. Apart from a reduction in methane and N2O emissions, vast agricultural areas would become unused, mostly as a result of reduced cattle grazing, and could take up large amounts of carbon. Shifting worldwide to a healthy low-meat diet would reduce the costs of stabilising greenhouse gases at 450 ppm CO2 eq. by more than 50%.
Abstract
Climate change mitigation policies tend to focus on the energy sector, while the livestock sector receives surprisingly little attention, despite the fact that it accounts for 18% of the greenhouse gas emissions and for 80% of total anthropogenic land use. From a dietary perspective, new insights in the adverse health effects of beef and pork have lead to a revision of meat consumption recommendations. Here, we explored the potential impact of dietary changes on achieving ambitious climate stabilization levels. By using an integrated assessment model, we found a global food transition to less meat, or even a complete switch to plant-based protein food to have a dramatic effect on land use.
