  • The UN Climate Panel said in a 2007 report that by 2020 cuts of between 25-40% subject to an international agreement, Australia would commit to a reduction of 25% from the 2000 level by 2020 (previously, there was to be a reduction of 15% Australian 2020 targets include a 20% of power supplied from renewables The European Union has committed to a 20 percent reduction by 2020, and says it will go to 30 percent if others also make strong cuts. Japan targets 25% reduction by 2020 compared with 1990 levels. US target is to be at 1990 levels by 2020 According to the Intergovernmental Panel for Climate Change (IPCC), developed economies must reduce greenhouse gas emissions by 80-95% by 2050 in order to avoid dangerous climate change. What does this world look like? New power sources, renewable, nuclear, clean coal? Cities? Transport? Work? Homes? Growth vs Sustainability or Growth & Sustainability? We are facing a Carbon Chasm – To cut emissions in developed economies by the required 80% by 2050, we need to see a minimum annual global reduction rate of 3.9% per annum. However, analysis of reduction targets from the Global 100 companies shows they are currently on track for an annual reduction of just 1.9% per annum. If we were all to continue on that trajectory we will not achieve the required reductions until 2089
  • 6% is the same as the steel industry Data centre growth in demand. IDC analyst Michelle Bailey says US companies spent approximately $5.8 billion powering servers in 2005 and another $3.5 billion or more keeping them cool. That compares with approximately $20.5 billion spent purchasing the equipment. The cost and availability of electricity is emerging as a key concern for IT managers when building data centres, in many cases trumping such traditional considerations as seismic stability, purchase price, and quality of life for employees
  • Outline holistic approach to Green IT must consider the all aspects of sustainabiltiy
  • Draw attention to lack of general awarness of these facts within IT deparments Consume less and save more Link this back to the Green IT Consulting Offering

  • © Accenture 2001 Phase 1 was exploiting low hanging fruit / energy efficiency Gartner estimate 15-20% achievement across the market Phase 2 of Green IT will build on this Lock sustainability into business processes Tackle more complex issues and opportunities Build KPIs esp energy efficiency into governance processes Phase 2 more joined up across org, Facilities, CSR, Cultural Change Team Energy (and increasingly carbon) will continue its progression to being a critical, costly and constraining resource The bar on good practice will continue to rise 3 -5 yrs Impact on governance and process Failure will be spiralling energy cost and potential reputation risk Facilities owner power bill = problem

  • These reasons cited for not establishing a Green TI policy are generic and not Green IT specific. If there was an increased understanding of the business benefits the barriers to Green IT policy would not be so high Source:

  • Dematerialisation – the substitution of high carbon products and activities with low carbon alternatives e.g. replacing face-to-face meetings with videoconferencing, or paper with e-billing SMART motor - motor is “smart” when it can be controlled to adjust its power usage to a required output SMART logistics - The logistics of this vast operation (including packaging, transport, storage, consumer purchasing and waste) are inherently inefficient. For instance, vehicles often carry little or nothing on return journeys SMART buildings - The term ‘smart buildings’ describes a suite of technologies used to make the design, construction and operation of buildings more efficient, applicable to both existing and new build properties SMART grids - A “smart grid” is a set of software and hardware tools that enable generators to route power more efficiently, reducing the need for excess capacity and allowing two-way, real time information exchange with their customers for real time demand side management
