Book (series)Methods for estimating greenhouse gas emissions from food systems
Part III: energy use in fertilizer manufacturing, food processing, packaging, retail and household consumption
2021Also available in:
No results found.This paper is part of a series detailing new methodologies for estimating key components of agri-food systems emissions, with a view to disseminate the information in FAOSTAT. It describes methods for estimating greenhouse gas (GHG) emissions from fossil fuel-based energy use in agri-food systems processes outside agricultural land, i.e. those associated with pre- and post-production activities – in an effort to inform countries of the environmental impacts of agri-food systems and the possible options to reduce them. -
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 (series)Methods for estimating greenhouse gas emissions from food systems
Part VI: fluorinated gas emissions
2023Also available in:
No results found.This paper is part of a series detailing new methodologies for estimating key components of agrifood systems emissions, with a view to disseminate the information in FAOSTAT. It describes methods for estimating greenhouse gas (GHG) emissions from the agrifood system, and in particular fluorinated gases (F-gases) from refrigeration systems in the food system cold chain, from food processing to food transport, retailing and household consumption processes. Based on the proposed methodology, we build a new database of GHG from F-gases used in the agrifood system, by country and with global coverage, for the period 1990–2021.
