In general, GHG emissions are estimated by multiplying activity data by the associated emission factor.
Emissions = activity data \u00d7 emission factor

Activity data refer to the quantitative amount of human activity resulting in emissions during a given time period. The annual activity data for fuel combustion sources, for example, are the total amounts of fuel burned over a year.

Emission factors are based on samples of measurement data, and are representative rates of emissions for a given activity level under a given set of operating conditions. It is the estimated average emission rate of a given pollutant for a given source, relative to units of activity.

Guidelines produced by the Intergovernmental Panel on Climate Change for countries reporting to the United Nations Framework Convention on Climate Change provide various methods for calculating GHG emissions from a given human activity. The methods for estimating emissions are divided into 'tiers,' each encompassing different levels of activity and technological detail. The same general structure is used for all tiers, while the level of detail at which the calculations are carried out can vary.

Greenhouse gas emissions are reported in carbon dioxide equivalents (CO2 eq), determined by multiplying the amount of emissions of a particular greenhouse gas by the global warming potential of that gas. Environment and Climate Change Canada (ECCC)

","comments_limitations":"The Greenhouse gas emissions indicators are comprehensive but some emission sources have not been included in the indicators because they are not reported in the National Inventory Report. Owing to their relatively small contributions to the total emissions, these excluded sources do not significantly affect the overall completeness of the inventory. A detailed explanation of the excluded emission sources can be found in Annex 5 of the National Inventory Report. Although reported in the National Inventory Report, emissions and removals from the land use, land use change and forestry sector are excluded from national totals and subsequently not reported as part of the Greenhouse gas emissions indicators.

En g\u00e9n\u00e9ral, pour \u00e9valuer les \u00e9missions de GES, on multiplie les donn\u00e9es sur les activit\u00e9s par le facteur d'\u00e9mission associ\u00e9.

\u00c9missions = donn\u00e9es sur les activit\u00e9s \u00d7 facteur d'\u00e9mission

Les donn\u00e9es sur les activit\u00e9s se rapportent \u00e0 la somme quantitative d'activit\u00e9s humaines entra\u00eenant des \u00e9missions durant une p\u00e9riode donn\u00e9e.

Les facteurs d'\u00e9mission sont bas\u00e9s sur un \u00e9chantillonnage de mesures de donn\u00e9es effectu\u00e9es et sont des taux repr\u00e9sentatifs des \u00e9missions pour un niveau d'activit\u00e9 donn\u00e9 selon un ensemble pr\u00e9cis de conditions d'exploitation.
