The present document was developed jointly by ETSI TC EE and ITU-T Study Group 5. It will be published respectively by ITU and ETSI as Recomme

35、ndation ITU-T L.1410 and ETSI Standard ETSI ES 203 199, which are technically-equivalent.

Introduction The present document has been developed to complement ISO 14040 1 and ISO 14044 2 for the environmental assessment of the li

37、fe cycle impact of ICT goods, networks and services. The present document defines a set of requirements to reflect the quality that practitioners should strive for. At this stage some of the requirements put forward here are considered as challenging due to life cycle assessment (LCA) tool limitatio

38、ns, a lack of data, limitations in data granularity, etc. It is thus recognized that compliance to all requirements in the present document may not be possible at the time the present document is published. However, to foster results of LCAs becoming more transparent and, for the quality of data and

39、 LCA tools to improve over time, the present document is defining the requirements outlined in the following pages. The present document requires that deviation(s) from the requirements are clearly motivated and reported. For further details regarding compliance refer to clause 5.2. The development

40、of information and communication technologies (ICTs) has led to concerns regarding its environmental impact. Taking into consideration the ongoing efforts within the United Nations Framework Convention on Climate Change b-UNFCCC to combat climate change, ITU-T and ETSI decided to enhance their previ

41、ous work by jointly developing an internationally agreed methodology to help the ICT sector to assess the environmental impact of ICT goods, networks and services. The present document also gives guidance to the assessment of software. Unlike many products and services sold in the world today, ICT d

42、istinguishes itself by its double-edged nature. On the one hand, ICTs have an environmental impact at each stage of its life cycle, e.g. from energy and natural resource consumption to e-waste. On the other hand, ICTs can enable vast efficiencies in lifestyle and in all sectors of the economy by the

43、 provision of digital solutions that can improve energy efficiency, inventory management and business efficiency by reducing travel and transportation, e.g. tele-working and video conferencing and by substituting physical products for digital information, e.g. e-commerce. ETSI ETSI ES 203 199 V1.3.1

44、 (2015-02) 8These different levels of impact are acknowledged in some academic literature as the three order effects of ICTs: First order effects (or the environmental load of ICTs): the impacts created by the physical existence of ICTs and the processes involved, e.g. energy consumption and GHG emi

45、ssions, e-waste, use of hazardous substances and use of scarce, non-renewable resources. Second order effects (or the environmental load reduction achieved by ICTs): the impacts and opportunities created by the use and application of ICTs. This includes environmental load reduction effects which can

46、 be either actual or potential, such as travel substitution, transportation optimization, working environment changes, use of environmental control systems, use of e-business, e-government, etc. NOTE: E.g. if an ICT service offers a reduced need for transport, the travel substitution replacing trans

47、portation by car is actual - the car does not run - whereas the reduced need for travel by public transport is potential - the plane, train or metro is still running if the timetable has not changed. However, the large scale deployment of video conferencing and tele-working (telecommuting) in the fu

48、ture will likely change lifestyles and impact on social structure and while it is expected to substantially reduce traffic volume, further research is required to assess what the full impact (including rebound effects) will be. Other effects: include the impacts and opportunities created by the aggr

49、egated effects on societal structural changes by using ICTs; particularly include, for some ICT services such as tele-working or video conferencing, the time gained by an end user using an ICT service which then may cause additional impact e.g. a leisurely drive and economic activities, which are difficult to track. Such additional impacts are often defined as “rebound effects“. Most of the benefits of ICTs lie in the second order effects via increased efficiency, transparency, speed of transactions, rapid market-clearing, long-tail effects and so on. There are e
