Bristol Ict Workshop2

  1. 1. Bristol Green ICT Workshop Dave Zammit Neil Evans March 2009
  2. 2. The Camco Group is an international leader in identifying opportunities and providing solutions to carbon risk. Bristol ICT Carbon Footprint 1
  3. 3. Introductions Bristol ICT Carbon Footprint 2
  4. 4. Agenda Setting the scene Bristol ICT carbon footprint Activity A – your Green ICT progress Green ICT database and case studies Activity B – Group discussions on blockers/enablers and shared experiences with Green ICT Where next? Bristol ICT Carbon Footprint 3
  5. 5. Objectives 1. To inform attendees about the Bristol ICT project, Bristol’s ICT footprint, and what BCC and Connecting Bristol are planning on doing to tackle this as a specific climate change issue for the city 2. To discuss the range of Green ICT measures that exist and their potential for saving energy, carbon and costs 3. To understand the extent to which Green ICT measures have already been implemented 4. To understand what the barriers are to implementing these measures across Bristol and how BCC and Connecting Bristol can help Bristol ICT Carbon Footprint 4

  7. 7. Climate Change Update CO2 emissions and equilibrium temperature increases for a range of stabilisation levels Figure SPM.11. Global CO2 emissions for 1940 to 2000 and emissions ranges for categories of stabilisation scenarios from 2000 to 2100 (left-hand panel); and the corresponding relationship between the stabilisation target and the likely equilibrium global average temperature increase above pre-industrial (right-hand panel). Approaching equilibrium can take several centuries, especially for scenarios with higher levels of stabilisation. Coloured shadings show stabilisation scenarios grouped according to different targets (stabilisation category I to VI). Right-hand panel shows ranges of global average temperature change above pre-industrial, using (i) “best estimate” climate sensitivity of 3°C (black line in middle of shaded area), (ii) upper bound of likely range of climate sensitivity of 4.5°C (red line at top of shaded area) (iii) lower bound of likely range of climate sensitivity of 2°C (blue line at bottom of shaded area). Black dashed lines in the left panel give the emissions range of recent baseline scenarios published since the SRES (2000). Emissions ranges of the stabilisation scenarios comprise CO2-only and multigas scenarios and correspond to the 10th-90th percentile of the full scenario distribution. Note: CO2 emissions in most models do not include emissions from decay of above ground biomass that remains after logging and deforestation, and from peat fires and drained peat soils. {Figure 5.1} Bristol ICT Carbon Footprint 6
  8. 8. Met Office Hadley Centre The ten warmest years on record have occurred since 1997. Global temperatures for 2000-2008 now stand almost 0.2 °C warmer than the average for the decade 1990–1999. Bristol ICT Carbon Footprint 7
  9. 9. Climate Change Update It has been clear for some time that greenhouse gas emissions have been accelerating at a rate higher than even the worst-case emissions scenarios used by the Intergovernmental Panel on Climate Change (IPCC) in the 2007 report. Arctic Ocean Diversity (Arcod) “Hansen points out that when temperatures increased to between 2 and 3 degrees above today's level 3.5 million years ago sea levels rose by 25m, not the 59cm being predicted by the IPCC” Refers to James Hansen, Nasa Bristol ICT Carbon Footprint 8
  10. 10. Climate Change Update The Policy Climate Change Act 2008 •Legally binding targets: • GHG emission reductions of at least 80% by 2050 • CO2 emission reductions of at least 26% by 2020 •Carbon budgeting system • Caps emissions over five year periods • The first three carbon budgets will run from 2008-12, 2013-17 and 2018-22 •Committee on Climate Change • A new independent, expert body to advise Government • Annual reports to Parliament on the UK’s progress towards targets and budgets Bristol ICT Carbon Footprint 9
  11. 11. Climate Change Update The Carbon Reduction Commitment (CRC) •Mandatory auction based emissions “cap & trade” scheme •Designed to be revenue neutral • Auction revenues recycled back to participants based on their baseline (”footprint”) emissions and scaled by their actual emissions and position in “league table” •Aimed at large organisations not covered by CCA & EU ETS • Business & public sector •Designed to have a “light touch” administration •Administered by Environment Agency •Final guidelines due out end March ?

  22. 22. Data centres – Virtualisation of servers What is the issue? -The principle is to consolidate multiple operating systems onto one server. Barriers to virtualisation -In large organisations servers are often purchased through departmental budgets (server hugging) -Tenders often issue a performance spec for servers -Tenderers can respond to this by overspecifying -Spec should include a carbon emissions target. Bristol ICT Carbon Footprint 21
  23. 23. Data centres – Virtualisation of servers Benefits -increase server utilisation to between 60 and 80% (from a base of 10-20%) -The number of servers can be greatly reduced (in one example from 1,000 to 80) -A larger number of CPU’s per server means a lower electricity bill and lower maintenance costs -Less space required – typically 70% less -Reduce electricity bill by 70% -Reduce cooling requirement by 50% Bristol ICT Carbon Footprint 22
