Focus of the ICT sector supplement

• Focus on implementation of the GHG Protocol
  hence adheres to principles of GHG Protocol and
  its interpretation of ISO
• Practitioners Guide
• written by practitioners for practitioners
• focus on how to assess GHG emissions of ICT
  products (goods services)
• examples / case studies
• supporting data
• Reference and use of existing work and
  approaches for embodied carbon - PAIA, iNEMI

ICT sector supplement
GHGP ICT sector supplement covers goods and
services, focus on assessment of greenhouse gases
(no other environmental factors) ITU-T
methodology more high level, focused on
different activities such as utilization of
software, storage of goods and work processes.
Does not divide into use phase, embodied
emissions and operational activities. ETSI
methodology wider LCA - covers for example
emissions to water and ground, water and land
use. Doesnt offer assessment/calculation
approach EC pilot project will test
compatibility

Telecom Network Services GuideObjectives

• Provides guidance for ICT stakeholders in
  calculating GHG emissions associated with telecom
  network services (TNS)
• Offers methodology approach and options to
  identify GHG reduction opportunities over the
  life cycle of a service
• Provides a means of understanding emissions
  sources and prioritizing them to then help in
  reducing them
• It is NOT a guide for product labeling or
  comparative assertion
• TNS comprises 3 core elements
• Customer domain
• Service platform
• Operational activities
• Guide covers
• Scope, boundary, functional unit
• Methodologies, hierarchical approaches,
  references for details
• Generic topics covered in Intro / Overview

TNS Element Use a Embodied b
Customer domain Detailed use phase measurement directly measure power consumption of the ICT equipment through physical power monitoring under specific operating conditions and usage profile. Use estimation estimate typical energy consumption of ICT equipment based on categorical equipment type, anticipated usage profile, and relevant country/region location of usage. 3. LCA phase ratio modeling use-phase GHG emissions can be modeled as a percentage of the total life cycle GHG emissions, accounting for the equipment type, usage profile and country/region of usage. ICT Equipment Detailed LCA use data from detailed LCA to determine the ICT equipments GHG emissions. Embodied estimation estimated GHG assessment from techniques such as Components estimation techniques based on categorical component similarities (e.g. iNEMI ICT LCA estimation) Equipment estimation techniques based on ICT equipment type parametization (e.g. PAIA laptop parametization) 3. LCA phase ratio modeling embodied GHG emissions can modeled as a percentage of the total life cycle GHG emissions. ICT Supporting Infrastructure treated separately

Service platform Bottom-up model total service platform energy consumption can be calculated bottom-up from an inventory of equipment. Coarse/fine-grain models a combination of data requirements and energy modeling parameters to yield a certain level of information for the use phase. Top-down model apportionment of energy to individual telecom services calculated with ratio of capacity used by customer or service and mean traffic being carried by the network. Follow approaches as per Customer Domain Embodied phase 2. Screening estimation where significance is low, use existing LCA studies as proxies.

Emissions Elements Operational Activities
Approaches for assessing GHG emissions of Operational Activities (Listed in decreasing order of accuracy) Approaches for assessing GHG emissions of Operational Activities (Listed in decreasing order of accuracy)
TNS Element Use e Embodied f
Operational activities and non-ICT infrastructure Primary Data Assessment - assess GHG emissions from resources (people and equipment) involved in delivering the TNS service, their specific work assignments, and their time allocations. Secondary Data Assessment - assess GHG emissions from resources involved in delivering the TNS service by using costs and conversion factors from economic input / output tables and apportionment factors based on the type and extent of operational activities. Primary Data Assessment use primary data from a detailed life cycle assessment (typically carried out by the owner / maintainer of the operational / non-ICT infrastructure). 2. Screening estimation from a practical standpoint, these activities in the embodied phase may be represented as either a simplified percentage of the total LCA emissions, e.g. 1, or it may be excluded due to the relatively small impact (less than 1).

Customer Domain Use / Embodied Ratio Modeling
Approach - Example

• Example a small chassis router has typical
  active power consumption of 100 W at 24x7
  utilization, and a life expectancy of 7 years
• Step 1 calculate the routers use-phase GHG
  emissions
•  
• Euse 100 W x 8760 hrs/yr x 7 yrs x 1
  kwh/1000 Wh x 0.537 kg CO2e/kwh
•  
• Euse 3293 kg CO2e GHG conversion factor for
  appropriate region of use
•  
• Step 2 estimate the routers embodied-phase GHG
  emissions using historical LCA data showing the
  LCA ratio for use / embodied emissions for
  different equipment types (see table)
•  
• Eemb Euse 20 80 3293 kg CO2e x (20
  / 80) 823 kg CO2e
• Eemb 823 kg CO2e

Example Data
Equipment Category Use / Embodied Phase LCA Ratio (Cu and Ce)
Wireless Access Point 75 / 25
Router, small chassis 80 / 20
Telepresence system 85 / 15
Note full life cycle GHG emissions can also be
estimated as Euse Eemb 4116 kg CO2e
