| Scope |
Organisation env. accounting
|
Product env. assessment
|
|
|
|
|
| System(s) covered by the methodology |
o ICT activities in non-ICT organisations o ICT organisations |
|
| Goals |
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. |
|
| Generic features |
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. |
|
| ICT-specific features |
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. |
