Scope 3 emissions are challenging for many companies doing GHG reporting or target-setting. This is due to the complexity of tracking processes upstream and downstream of the value chain of their services. Telstra engaged Edge to conduct their Scope 3 Greenhouse Gas emission assessment. Edge assessed all 13 Scope 3 categories, including the embedded emissions of Telstra’s suppliers. The deliverables were a CDP-compliant emissions report and a calculation tool to facilitate annual updates by Telstra.
