Emissions = Activity Data * Emission Factors
Estimation of GHG emissions
Activity data: • data on the magnitude of a human activity resulting in emissions or removals of GHG during a given period of time (IPCC, 1996);
• typically derived from statistic;
• availability and quality as primary driving factors that determine the accuracy and reliability of the GHG emissions inventory.
Emission factor: • average emission rate of a given GHG, relative to units of the activity data (IPCC, 1996).
From IPCC, 2006
Main activity data used for the emissions estimate
Rice Cultivation Harvested area
Enteric Fermentation Manure
Number of animals
Synthetic Fertilizers N Fertilizer consumption
Crop Residues Yields & Harvested area
Recommendations IPCC 2006 Guidelines on activity data
• Importance of official national data
• FAO can support Member Countries with:
– global datasets (FAOSTAT and FRA);
– guidance on performing surveys and census; and
– cross-check national and international datasets to ensure completeness and consistency in GHG inventories.
FAOSTAT as a source of activity data
• FAO has a long maintained global datasets on agricultural and forest data, extremely valuable for National Greenhouse Gas (GHG) inventories for the AFOLU sector (IPCC, 2006).
• FAOSTAT provides a global coverage of statistical data in different domains:
• Production: Livestock, Crops • Resources: Fertilizers, Land
• Data are collected through questionnaires compiled by Member Countries.
