Joannes De Wilde - Fiber for a greener future

  1. 1. Fiber for a greener future (SUDEFIB) Committee Joannes De Wilde FTTH Council Europe Amsterdam CUD 23 september 2008
  2. 2. Sustainable Development and FTTH Broadband usage is an opportunity for sustainable development FTTH is maximizing the offer for new services w/ minimum materials & maintenance How FTTH participate to sustainable development taking into account networks sourcing, implementation, consumption, recycling? Our mission: Quantify the Sustainable Development Impact of FTTH solutions looking at various European cases
  3. 3. Tele-presence: A good Busi…Home
  4. 4. FTTH is creating a new environment More Less • Teleworking • Life constraints & stress • Video-conference • Inefficiencies of services • Medicine, healthcare • Intense operations • Governance • Infrastructures/transport • Education • Environmental changes • P2P, exchanges • Collective costs • Video surveillance, etc. • Business • Personal • Family benefits • Societal • Local enhancement
  5. 5. Study Introduction • Information society network are providing solutions for heavy energy consumptions sectors, such as transport and building sectors • FTTH networks bring environmental benefits in many fields. The present study focuses specifically on the areas of teleworking and telemedicine • FFTH solutions provide higher bandwidth than all other broadband solutions. The project compares the environmental impact of a network to these associated benefits • The use of Life Cycle Assessment (LCA) to illustrate this comparison was made by PricewaterhouseCoopers to generate the necessary quantitative data This work has been done according to ISO 14040 standard
  6. 6. Hypothesis • Data sources and modeling were mainly provided by the FTTH Council SUDEFIB (Sustainable Development Fiber) Committee Data are weighted as European average • FTTH network deployment – 3 scenarios were considered for the calculation: urban dense, urban wide and rural areas. – 4 types of deployment techniques are considered (existing ducts or urban sewage, traditional trench, micro-trench, aerial hanging) – The life span of the FTTH passive infrastructures was chosen as 50 years • Selected benefits – Teleworking, telemedicine and home assistance are assessed – Telemedicine looked up three cases: teledialysis, telemedical meetings and medical imaging transfer – From the current trends (2010-2011) in FTTH networks use, we have chosen the following percentage - 10% of the working population could telework 3 days per week - 20% of the population 75 years old and over could benefit from home assistance
  7. 7. Example of a technique modelling Ready-mixed 63 m3 3 MJ Light fuel oil concrete (Blowing machine consumption) 130 m2 1000 m Road bitumen Outdoor optical fiber cable 1 km of micro-trench 1605 L 116 kg Diesel oil Polyethylene (HDPE) (Civil works engine consumption )

  9. 9. Analysis of results & main outcomes • As a main quantitative finding, the environmental impact of the deployment of a typical FTTH network will be positive in less than 10 years considering only the three selected services • The use of the network (power consumption) represents only 6% of the total impact • Additional either existing or developing applications will further emphasize these results • Beyond its environmental-friendly aspects, FTTH solutions offer additional social and economical benefits
  10. 10. Depreciation of FFTH network (in years) Total Primary Energy 12.0 10.0 Depletion of abiotic Human Toxicity 8.0 b 6.0 resources 4.0 2.0 0.0 Eutrophication Greenhouse effect Photo-oxidant Air Acidification formation * For a deployment scenario made of 60% in urban dense areas, 30% in urban wide areas and 10% in rural areas • Years (0.0 – 12.0) represents the depreciation of the FTTH Network. • quot;Total impact of fiber network implementationquot; takes into account full life cycle including production of passive and active equipments, transport, implementation, power consumption and end of life. • quot;Environmental savingsquot; are represented by one of teleworking, home assistance and the three telemedicine case studies.
  11. 11. Relative contributions of the different FFTH network deployment phases to climate change potential impacts 4. Passive fiber network deployment 78% 5. Network power consumption 3. Transport 6% 0% 1. Cable and passive 6. End of life 2. Active 1% equipment equipements production production 7% 8% • Regarding the potential greenhouse gas impact, the deployment phase is predominant and represents approximately 80% of the total impact of FTTH network • In particular, the key impacting parameter over the carbon emissions is the length of new ducts (meters) per home passed
  12. 12. Normation • If we consider only the projection of FTTH number of user according to IDATE (20 millions for 2015) for the first 10 years of network implementation, greenhouse gas emission savings per user are of 250 kg approximately. This is equivalent to a car travelling 1 700 kilometers. For the next 10 years .... • Consequently, sustainability of FTTH solutions will be demonstrated if: – user experience is growing – bottlenecks such as network access are removed • The present study considers an overall approach of FTTH alternative networks and associated services. In particular, it considers PON and Point to Point configurations using aggregated data
  13. 13. Other contributions FTTH can contribute to other fields not assessed in the present study (see also DG JRC report quot;The future impact of ICTs on environmental sustainabilityquot;) • Energy demand • Supply chain management • E-commerce • Tele-meetings • Dematerialized products and services • Intelligent transport systems • Facility management • Production progress management • Improve service and product utilization
  14. 14. Conclusion • This study is based on European inputs. An eco-design approach can be adopted on a case by case basis. The scope can be extended to other geographical contexts (US and Asia through local FTTH Councils work) or to specific local deployments • FTTH network solutions represent a responsible investment for: – Operators – Public bodies – Shareholders – Utilities • FTTH networks provide decisive leverage to policy makers “FTTH networks enable society changes for a sustainable future”… just imagine!
