Food systems account for over one-third of global greenhouse gas emissions |
Food system emissions were estimated at 18 billion tonnes of carbon dioxide equivalent in 2015, or 34 per cent, though down from 44 per cent in 1990, indicating gradual decline even as these emissions kept increasing.
The report was co-authored by Francesco Tubiello, a senior statistician and climate change specialist at the UN Food and Agriculture Organization (FAO), in collaboration with researchers at the European Commission's Joint Research Centre in Ispra, Italy.
It presents a database, known as EDGAR FOOD, which can be used to assess how changes in consumer behaviour or technology, may impact food system-derived greenhouse gas emissions.
EDGAR FOOD incorporates key land-use data for over 245 countries that has been compiled by FAO. The information goes back to 1990 and spans multiple sectors, which will enable tracking of ongoing and future trends.
Food systems more energy intensive
The report highlights how global food systems are becoming more energy intensive, reflecting trends in retail, packaging, transport and processing, whose emissions are growing rapidly in some developing countries.
Roughly two-thirds of food system emissions come from agriculture, land use and changes in land use. The figure is higher for developing countries, but is also declining significantly as deforestation decreases and food processing, refrigeration and other “downstream activities” increase.
