During the last financial year, GHG emissions totalled 1,678 tonnes compared to 1,015 tonnes for the prior year. This increase is mainly attributable to emissions generated by employees commuting between their home and the head office, which is accounted for in 2012-2013 for the first time.
NOx, SOx and other air pollutant emissions are calculated using data on fossil fuel consumption (natural gas, diesel, propane and gas) and electricity consumption. In 2012-2013, excluding emissions related to commuting, emissions totalled 4.5 tonnes, compared to 4.1 tonnes for the prior year. This change is attributable to an increase in business transportation.
