Suncor: report on sustainability 2014

2013 greenhouse

gas performance

Our Report on sustainability provides an annual

accounting of our greenhouse gas (GHG) emissions,

both in terms of absolute emissions and emissions

intensity. The latter is calculated by using

full-year net production and the carbon dioxide

equivalent (COe) emitted from operated facilities.

corporate GHG intensity is calculated based on net corporate production,
which also removes inter-business unit transfers.
