Other environmental impacts
|System(s) covered by the methodology||
o ICT activities in non-ICT organisations
o ICT organisations
o Identifying energy consumption and GHG impacts of the organisation
o Providing information to decisions-makers in organisations
o Selecting relevant indicators for monitoring of environmental performance
o Understanding improvements in GHG emissions over time
o Assessing first and second order effects defined in ITU-T L.1410 emerging from the use of ICT in non-ICT organisations.
o GHG offset is not taken into account.
o For ICT organisations, it can be used as a supplement to ISO 14064-1 and GHG Protocol standards. Scope 1 and Scope 2 GHG emissions shall be included. GHG emissions in scope 3 should also be included. For scope 3 GHG emissions, a reference table indicating the reporting structure and scope 3 sources is given in Appendix I.
o The general steps include:
o An uncertainty assessment for GHG emissions shall be performed in accordance with clause 5.4 of ISO 14064-1 (ICT organisations)
o The result needs to be aggregated to an organisational level and on an annual basis.
o Assessing GHG impact and energy consumption of ICT in organisations, the following aspects shall be addressed in accordance with the considered scopes:
o For scope 3 GHG emissions, impact from all life cycle stages except the use stage should be divided by the operational life time to get the yearly impacts.
o Cut-off principles described in ITU-T L.1410 are applicable to scope 3 categories.
