Greenhouse gas (GHG) emissions related to food consumption add to production or territorial accounts by sequestering carbon leaked by trade. Here we assess consumption-based global food emissions between 2000 and 2019 and the underlying drivers using a physical trade flow approach and structural decomposition analysis. In 2019, emissions across global food supply chains reached 30 ± 9 % of anthropogenic greenhouse gas emissions, largely driven by beef and dairy consumption in rapidly developing countries, while per capita emissions in developed countries with a high percentage of livestock of food fell. Emissions outsourced through international food trade dominated by beef and oilseeds increased by ~1 Gt _CO2which is mainly caused by increased imports from developing countries.
