ITU-T SERIES L SUPP 57 PDF

This Supplement to the L.1420-series of Recommendations gives guidance for telecommunication operators to assess their Scope 3 emissions. This guidance has been jointly developed with the Global Enabling Sustainability Initiative (GeSI) and the GSM Association (GSMA).

It harmonizes methods for telecommunication operators to assess and report their Scope 3 GHG emissions, and to increase the coverage and transparency of the reporting. Based on criteria including association with portfolios and the control and complexity of reporting, this guidance prioritizes Categories 1 to 2 and 11 of the GHG Protocol (which addresses the life cycle impact of company portfolios) in particular and Category 3 (which is closely linked to Scope 1 and 2), although all categories are addressed.

This guidance is intended to supplement, not supersede, existing standards. Thus, different parts present various levels of detailed guidance, as needed.

Its technical content is equivalent to the technical content of the joint publication "Scope 3 Guidance for telecommunication operators" released jointly in 2023 by GSMA, GeSI and ITU-T.
