20、umption and greenhouse gas (GHG) emissions related to their operations. It provides the necessary knowledge to prepare inventories and meet the societal demands emerging from a low-carbon economy and the challenge of higher energy prices. The Recommendation focuses on the energy consumption and GHG

21、emissions resulting from ICT activities and ICT organizations. This Recommendation covers The assessment of the life cycle perspective environmental impact of ICT goods, networks and services used by a non-ICT organization (“ICT in organizations“), e.g., PCs, servers, data centers and networks withi

22、n the organizations premises, based on the Recommendation ITU-T L.1410 and an aggregation to an organizational level for first and second order effects. The assessment of the environmental impact of an ICT organization (“ICT organizations“) based on ISO 14064-1 and b-GHG Protocol. The interpretation

23、 of these impacts. The reporting of these impacts in a transparent manner. Rec. ITU-T L.1420 (02/2012) 1 Recommendation ITU-T L.1420 Methodology for energy consumption and greenhouse gas emissions impact assessment of information and communication technologies in organizations 1 Scope The increasing

24、 proliferation of information and communications technology (ICT) has led to concerns regarding its environmental impact. Taking into consideration the ongoing efforts within the United Nations Framework Convention on Climate Change (UNFCCC) to combat climate change, ITU-T decided to develop an inte

25、rnationally agreed upon methodology to help the ICT Sector to make an inventory of the environmental impact, including greenhouse gas emissions and energy consumption, of ICTs in organizations. This Recommendation can be used to assess the energy consumption and GHG emissions of ICT related to organ

26、izations for two different purposes. Firstly, it can be used to assess the life cycle GHG emissions (first and second order effects) emerging from the use of ICT in non-ICT organizations, based on the Recommendation ITU-T L.1410. Secondly, it can be used as a supplement to ISO 14064-1 and to b-GHG P

27、rotocol for ICT organizations intending to assess their own organizational energy consumption and GHG related impact. This Recommendation is intended to allow organizations to assess their direct GHG emissions (generally referred to as scope 1), their indirect GHG emissions (generally referred to as

28、 scope 2) and their other indirect GHG emissions (generally referred to as scope 3). It also allows organizations to assess their energy consumption by developing an energy inventory focusing on secondary energy used by the assessed organization itself. However, it should be noted that this Recommen

29、dation will not address: GHG removal, which needs not be considered since ICT activities do not directly remove GHG, Other effects (apart from first or second order effects), such as rebound effects, since these effects are still under research to a large extent, Other environmental impacts like for

30、 example depletion of abiotic resources, acidification, eutrophication, stratospheric ozone depletion, photo-oxidant formation and human toxicity. 1.1 Assessment of impact from the use of ICT in non-ICT organizations For the assessment of the first and second order effects when using ICT in non-ICT

31、organizations, this Recommendation defines an assessment framework (principles, concepts, requirements and methods) to be used by any kind of organization (except for ICT organizations) when quantifying and reporting the energy consumption and the GHG emissions of ICT activities. 1.2 Assessment of i

32、mpact from ICT organizations For the assessment of an ICT organization, this Recommendation provides a methodology to assess both the energy consumption and the GHG emissions of its activities over a certain period of time for the following emissions: direct GHG emissions energy indirect GHG emissio

33、ns and other indirect GHG emissions. 2 Rec. ITU-T L.1420 (02/2012) This Recommendation covers the following items: design and development of the inventory components of the inventory quality management requirements of the inventory reporting of the inventory results. 2 References The following ITU-T
