Please enter the most recent measurement for your scope 3 emissions in tonnes of CO2 equivalent. Please state when this was last measured and provide further information on the scope and method of measurement, if applicable, in the notes section. If you do not measure scope 3 emissions, please enter zero as your numerical answer and state this clearly in the notes section.
For more information on scope 1, scope 2, and scope 3 greenhouse gas (GHG) emissions, please see the knowledge base article for question XB6.
Scope 3 emissions are defined as follows by the Greenhouse Gas (GHG) Protocol’s Corporate Accounting and Reporting Standard:
Scope 3: Other indirect GHG emissions
Scope 3 is an optional reporting category that allows for the treatment of all other indirect emissions. Scope 3 emissions are a consequence of the activities of the company, but occur from sources not owned or controlled by the company. Some examples of scope 3 activities are extraction and production of purchased materials; transportation of purchased fuels; and use of sold products and services.
Scope 3 emissions are the hardest scope to measure. Scope 3 is an optional reporting category and it is quite common for an organisation to measure its scope 1 and scope 2 emissions, but not its scope 3 emissions. If you do not measure scope 3 emissions, please enter zero as your answer and state this clearly in the notes section.
Whilst measuring scope 1, scope 2, and scope 3 emissions is relatively new, there are a number of resources available to support you. A good place to start is the The Corporate Accounting and Reporting Standard from GHG Protocol. GHG Protocol have also developed a suite of calculation tools to help.
We encourage you to speak openly with your clients and customers about measuring greenhouse gas emissions, if it is something they request of you. There is a lot of work to be done in this space and it is expected to mature over time through cross-sector collaboration.
