BookletThe share of agri-food systems in total greenhouse gas emissions
Global, regional and country trends 1990–2019
2021Also available in:
No results found.Emissions from agri-food systems are those generated by farm production activities (crops and livestock), land use change and pre- and post-production processes. The first two components result in emissions generated on agricultural land, while the third refers to emissions from supply chain processes including transport, processing and input manufacturing, as well as from household consumption and waste. While emissions on agricultural land are well characterized in the literature, with FAO disseminating annual updates that are widely used and inform the periodic assessments of the Intergovernmental Panel on Climate Change, the quantification of emissions generated in agri-food systems beyond the farm gate is a more recent endevour. This analytical brief presents results of the first database on agri-food systems beyond the farm gate developed by FAO. Statistics on absolute emissions and their shares are disseminated at the country, regional and global level, over the period 1990–2019. The database covers, in addition to emissions on agricultural land, pre- and post-production processes in agri-food systems, such as those linked to: i) the production of inputs (fertilizers, materials for food packaging); ii) energy generation and consumption in food supply chains (food processing, transport and retail) and at the household level (cooking and refrigeration); and iii) waste disposal (such as in landfilling, incineration and wastewater management). -
Book (stand-alone)Agriculture, forestry and other land use emissions by sources and removals by sinks
1990-2011 Analysis
2014This report discusses new knowledge on anthropogenic greenhouse gas (GHG) emissions from agriculture, forestry and other land use (AFOLU) activities made available through the new FAOSTAT Emission database. The database is available globally, with country detail, for all agriculture, forestry and land sub-categories available in FAOSTAT and in the Forest Resources Assessment (FRA). GHG emissions are computed from official national activity data and geo-spatial analyses, applying international st andard methodologies of the Intergovernmental Panel on Climate Change (IPCC) to ensure consistency with GHG Inventory processes established under the climate convention. The analysis shows increases in emissions of agriculture (from 4.6 to 5.0 Gt CO2 eq yr-1 in 1990s and 2000s; 5.3 Gt CO2 eq yr-1 in 2011), decreases in deforestation rates (from 4.6 to 3.8 Gt CO2 eq yr-1 in 1990s and 2000s; 3.7 Gt CO2 eq yr-1 in 2010), and decreases in forest sinks, albeit with a reversal since the mid-2000s (f rom -2,9 to -1.9 Gt CO2 eq yr-1 in 1990s and 2000s values; -2.1 Gt CO2 eq yr-1 in 2010). At the same time, the data show that GHG intensity of products (i.e., GHG emissions per unit commodity produced) decreased during 1990-2010, but that if no further mitigation measures and technical efficiency improvements are implemented, future emissions may further increase by up to 30% by 2050. Better information on AFOLU emissions is critical in many developing countries, given the potential to identif y and fund actions that can usefully bridge national food security, resilience, mitigation and development goals into one coherent package. -
Brochure, flyer, fact-sheetFAO’s work on Climate Change: Greenhouse Gas Emissions from Agriculture, Forestry and Other Land Use 2016At the Paris climate conference (COP21) in December 2015, 195 countries adopted the first-ever universal global climate agreement that sets out a global action plan to limit global warming to well below 2°C. A key outcome was the Enhanced Transparency Framework (ETF) to build trust and confidence on countries’ contributions and progress.
