The Growing Interdependence of the Internet and Climate Change

  1. 1. Invited Talk Negotiating the Downturn: Emerging Stronger Australian Industry Group National Forum Parliament House Canberra, Australia August 17, 2009 The Growing Interdependence of the Internet and Climate Change Dr. Larry Smarr Director, California Institute for Telecommunications and Information Technology Harry E. Gruber Professor, Dept. of Computer Science and Engineering Jacobs School of Engineering, UCSD
  2. 2. Australia’s National Broadband Network (NBN) Can Be Leveraged to Speed Climate Goals • NBN Goals – Connect 90% of Households with Fiber in Eight Years – Remaining 10% by Satellite or Wireless – 100 Mbit/s Broadband Per House – Driven by Consumer Internet, Telephone, Video – “Triple Play”, eHealth, eCommerce… • “Smart” Electric Grid – Reduce Household and Building Energy Usage – Avoid Peak Loading • Video Conferencing to Avoid Transportation • Plug-In Hybrid with Renewable Electricity Generation • Cloud Computing and Storage at Renewable Sites
  3. 3. ICT is a Critical Element in Achieving Countries Greenhouse Gas Emission Reduction Targets GeSI member companies: • Bell Canada, • British Telecomm., • Plc, • Cisco Systems, • Deutsche Telekom AG, • Ericsson, • France Telecom, • Hewlett-Packard, • Intel, • Microsoft, • Nokia, • Nokia Siemens Networks, • Sun Microsystems, • T-Mobile, • Telefónica S.A., • Telenor, www.smart2020.org • Verizon, • Vodafone Plc. Additional support: • Dell, LG.
  4. 4. The Earth is Warming Over 100 Times Faster Today Than During the Last Ice Age Warming! Monnin, et al., Science v. 291 pp. 112-114, Jan. 5, 2001. http://scrippsco2.ucsd.edu/program_history/keeling_curve_lessons.html CO2 Rose From CO2 Has Risen From 185 to 265ppm (80ppm) 335 to 385ppm (50ppm) in 6000 years or in 30 years or 1.33 ppm per Century 1.6 ppm per Year
  5. 5. Global Climate Disruption Early Signs: Arctic Summer Ice is Rapidly Decreasing “The Arctic Ocean will be effectively ice free sometime between 2020 and 2040, although it is possible it could happen as early as 2013.” --Walt Meier, Research Scientist at the National Snow and Ice Data Centre at the University of Colorado http://news.cnet.com/8301-11128_3-10213891-54.html
  6. 6. CO2 Emissions From Energy-Shell ”Blueprint” Scenario: An Aggressive CO2 Emission Reduction Scenario www-static.shell.com/static/public/downloads/brochures/corporate_pkg/scenarios/shell_energy_scenarios_2050.pdf China and India resisted signing up for a global goal of halving greenhouse gas emissions by 2050.—Reuters July 8, 2009 China India
  7. 7. In Shell’s “Blueprints” Scenario, 60% of Electricity is Generated by Renewables by 2050 90% of All OECD Coal and Gas Power Plants Use Carbon Capture and Sequestration
  8. 8. Ice Core Record Has Been Extended Using Plankton: Today’s CO2 is Higher Than in Last 2 Million Years! With No Policy Change, MIT Estimates ~900ppm by 2100 550 Possible Level by 2100, Shell “Blueprints” Scenario 500 450 400 Today’s CO2 Level 350 Hönisch, et al. Science 19 June 2009 Vol. 324. pp. 1551 - 1554
  9. 9. We are Unlikely to Limit CO2-Equivalent Emissions Below 450ppm Limiting GHG concentrations to 450 ppm CO2-equivalent is expected to limit temperature rises to no more than 2°C above pre-industrial levels. This would be extremely challenging to achieve, requiring an explosive pace of industrial transformation going beyond even the aggressive developments outlined in the Blueprints scenario. It would require global GHG emissions to peak before 2015, a zero- emission power sector by 2050 and a near zero-emission transport sector in the same time period…
  10. 10. We Are Transitioning to a New Climate State -- Unlike the Rapid Recovery with Acid Rain or Ozone Hole Susan Solomon, et al., PNAS 2/10/2009 v. 106 pp1704-9 Assumes CO2 Increases to a Maximum and Then Emissions Abruptly Stop Warming Persists for Over 1000 Years Warming During the Industrial Age -- Last 200 Years
  11. 11. “It Will Be the Biggest Single Peacetime Project Humankind Will Have Ever Undertaken”
  12. 12. The Global ICT Carbon Footprint is Roughly the Same as the Aviation Industry Today But ICT Emissions are Growing at 6% Annually! Most of Growth is in Developing Countries the assumptions behind the growth in emissions expected in 2020: • takes into account likely efficient technology developments that affect the power consumption of products and services • and their expected penetration in the market in 2020 www.smart2020.org
  13. 13. Reduction of ICT Emissions is a Global Challenge – U.S. and Canada are Small Sources U.S. and Canada Together Fall From 25% to 14% of Global ICT Emissions by 2020 www.smart2020.org
  14. 14. ICT Industry is Already Acting to Reduce Carbon Footprint

Application of ICT Can Lead to a 5-Fold Greater Decrease in GHGs Than its Own Carbon Footprint While the sector plans to significantly step up the energy efficiency of its products and services, ICT’s largest influence will be by enabling energy efficiencies in other sectors, an opportunity that could deliver carbon savings five times larger than the total emissions from the entire ICT sector in 2020. --Smart 2020 Report Major Opportunities for the United States* – Smart Electrical Grids – Smart Transportation Systems – Smart Buildings – Virtual Meetings * Smart 2020 United States Report Addendum www.smart2020.org
