7. GREENTOUCH (www.greentouch.org)
Bell Labs Initiated Global Research Consortium representing industry, government
and academic organizations
New Innovation Model for sustainability
Launched in May 2010
Focus on energy efficiency, sustainability and growth
Holistic and ambitious: Goal of 1000x
60 member organizations with 350+ leading scientists
Recognized by the World Economic Forum as an industry-led best practice toward
sustainability
Moving from fundamental research into the pre-competitive area through
standardization
Leading Green ICT: cooperation with other NGOs such as GeSI, ITU-T, GreenGrid,
Carbon Trust, ITRS
Deliver by 2015 Architectures, Specifications and Roadmap and
Demonstrate Key Technologies to Increase Network Energy
Efficiency by a Factor 1000 Compared to 2010
8. WHY NETWORK ENERGY EFFICIENCY?
Green Revenue
Services from Services
Bits
Total Traffic Delivered to User per second
Network Efficiency =
Total Power per User Watts
Carbon
Footprint Costs
Makes both Environmental and Economic Sense

11. CONCLUSIONS
ICT NETWORKS ARE GROWING RAPIDLY
• Scaling networks is becoming more difficult
• Bringing focus to energy efficiency
TRANSFORMING ICT AND RESEARCH COMMUNITIES
ICT NETWORKS ARE ORGANIZING TO ADDRESS CHALLENGES
FOR A • Dramatic, holistic change, but over long term evolution
SUSTAINABLE • Cooperative organizations
FUTURE
such as GreenTouch guiding (re)evolution
SEVERAL PROMISING RESEARCH DIRECTIONS
AND INITIAL RESULTS HAVE BEEN OBTAINED
• End to end network architectures and management
