Scope 3 Emissions

In addition to the Scope 1 and 2 emissions described in the LGOP Protocol, there are other sources of emissions related to local government operations, but over which local governments do not have clear operational or financial control. Scope 3 emissions include all of these other indirect emissions, which include, but are not limited to, emissions from:

o Transport-related activities from vehicles not owned or controlled by the local government (Chapter 12.2.1)

  • Employee commute
  • Business travel
  • Contracted service

o Supply chain services (Chapter 12.2.2)

  • Upstream production of materials and fuels (e.g. mining, extraction, refining, manufacturing, production of materials, fuels, and electricity, etc.)
  • Upstream and downstream transportation of materials and fuels
  • Waste generated by local government operations (if the local government does not own the landfill where waste is sent)

Although reporting Scope 3 emissions is considered optional, local governments are encouraged to identify and measure all Scope 3 emission sources to the extent possible. The LGOP Protocol provides guidance on assessing Scope 3 emissions in Chapter 12. Estimates for Scope 3 emissions are acceptable as long as the estimation approach is transparent and the data used for the analysis is adequate to support the objectives of the inventory. For any Scope 3 emission sources assessed, consider whether the quantification methodologies described elsewhere in the LGOP could be useful.
