Ontario Regulation 452/09 - Greenhouse Gas Emissions Reporting

Last updated: 23 September 2019
Guidelines for submitting GHG emissions report.

Formula for calculating CO2e
4. GHG emissions in tonnes of CO2e shall be calculated for the purposes of this Regulation by applying the following formula:

emissions in tonnes carbon dioxide equivalent = the sum of the total emissions of greenhouse gas i expressed in tonnes times the global warming potential for greenhouse gas i,

where,

E = the GHG emissions in tonnes of CO2e,

GHGi = the total emissions of greenhouse gas i expressed in tonnes,

GWPi = the global warming potential for greenhouse gas i,

n = the number of greenhouse gases,

i = the greenhouse gas.
