Greenhouse Gas Emissions Performance

Annual Greenhouse Gas Emissions

Greenhouse Gas Emissions from 2010-2017 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 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.
