Greenhouse Gas Emissions Performance

Annual greenhouse gas emissions by scope

Annual Greenhouse Gas Emissions

The stacked bar chart displayed on this page shows our annual greenhouse gas emissions for the years 2010 to 2017. Each year's emissions data are divided into scopes 1 (direct), 2 (indirect energy) and 3 (other indirect) emissions.

The chart highlights that scope 3 emissions have remained fairly steady over the previous six years, ranging from a low of 11,670 tCO2-e in 2012 to a high of 13,907 tCO2-e in 2010. In 2016 the University began off-setting the emissions related to air travel and fleet vehicle fuel use. This explains the reduction in scope 3 emissions commencing in 2015.

Scope 1 and 2 emissions vary across the years as a result of the operation of the gas powered trigeneration system located at the Melbourne (Bundoora) campus. In years when this system operated for the majority of the year scope 1 emissions, which include emissions from the combustion of natural gas, increase and scope 2 emissions from purchased electricity decrease. The opposite occurs in years when the system only operates for a portion of the year.
