EPA’s environmental performance

Emissions scopes and sources


We thoroughly review our operations to identify activities that generate greenhouse gas (GHG) emissions. This includes our direct activities, as well as those that occur upstream and downstream of these direct activities. Once all sources have been identified, they are categorised based on the Corporate Standard's approach to accounting and reporting, using scopes (Figure 1).Overview of scopes

Scopes help to distinguish between direct and indirect emissions sources. The Corporate Standard defines three scopes:

Scope 1

Direct GHG emissions that occur from sources that are controlled by the organisation. The following scope 1 emission sources were identified as part of our review:

  • natural gas – tenant
  • transport fuels – vehicle and boat fuel
  • refrigerants – building, kitchen, laboratory and vehicle refrigeration.

Scope 2

Indirect GHG emissions associated with purchased energy commodities including electricity and steam. Scope 2 emissions physically occur at the facility where the energy commodity is produced. The following scope 2 emission sources were identified as part of our review:

  • purchased electricity
  • high temperature hot water.

Scope 3

All other indirect GHG emissions that are a consequence of the activities of the organisation, but occur from sources not owned or controlled by the organisation. These refer to emissions from activities that are upstream or downstream including the supply chain and waste management. The following scope 3 emissions were identified as part of our review:

  • natural gas – trigeneration plant
  • base building natural gas – communal areas where EPA is a tenant
  • base building electricity – communal areas where EPA is a tenant
  • natural gas transmission and distribution losses – tenant and base building
  • electricity transmission and distribution losses – tenant and base building
  • fuel extraction, production and transportation
  • stationary fuels – backup generators
  • reticulated water
  • air travel
  • taxi travel
  • public transport
  • staff commuting
  • waste
  • office paper
  • catering services
  • printing and publication services
  • courier services.
