  1. Introduction To Green IT Sheraz Ahmad Mohammad El Wali

  2. Contents • Thefield of Green IT • IT compresstime, space and complexity • Green IT bridgesfromhumanscales to environmentalscales • Personal and institutional IT system • Human-Centered Computing and EHCC • BroadenHorizon(Time, Space and Complexity) • Key values of EHCC

  3. Greening Through IT Written by Bill Tomlinson Seeks to provide a framework for thinking about IT systems that address environmental topics Helps people to work more effectively to address the numerous environmental concerns currently facing the planet

  4. The Field of Green IT • Green IT describes a field at juncture of two trends

  5. The Field of Green IT • A survey of 49,243 teens from around the world revealed that 74 percent of them “believe that global warming is a serious problem and are more concerned about it than any other issue including drugs, violence or war” • Mobile phones were relatively rare a decade ago, now more than half the world’s people have them (Reuters, 2007)

  6. The Field of Green IT • Green IT brings together these two areas, environmental issues and IT, and explores the ways in which they connect to each other. • Examines the opportunities for IT to address issues related to the global ecosystem • “Computing is a crucial weapon in our armoury for ensuring the future of the planet” Professor Andy Hopper (2008),Professor of Computer Science at University of Cambridge

  7. Negative Environmental Aspects of IT • Not all facets of IT are environmentally favourable because power consumption around the world, and electronic waste (e-waste) is a fast-growing concern • According to a report by the Gartner research firm, the IT sector emits CO2 at a rate approximately equivalent to that of the airline industry (Mingay, 2007)

  8. Other Environmental Issues and their effects • Loss of forests effects reducing the planet’s ability to convert CO2 to breathable O2 • Humans produce large amounts of waste • In 2005, the world produced over 28 billion metric tons of CO2 from the consumption of fossil fuels (U.S. Environmental Protection Agency, 2007) • CO2 is one of the greenhouse gases (GHG) largely responsible for global climatic disruption.

  9. IT Compresses Time, Space, and Complexity • Technology has enabled us to do our intended work in short time and with less effort • IT compresses time in different ways such as - Storing abundant information for later retreival - Modeling the past and predicting future etc

  10. IT Compresses Time, Space, and Complexity • IT compress space such as - Communicate over long distance - Browse maps of the entire world - Transport goods and people around the globe etc • IT compress complexity - Devices to perform repetitive calculations - Establishing agreed on standards for cooperation of devices and people

  11. Green IT Bridges from Human Scales to Environmental Scales • IT can have negative as well positive effects on environmental sustainability • Innovative technologies has enabled us to farm, burn, mine, drive etc –negative impact • From these problem Green IT enables us to understand, discover, and act in the way to live sustainable • IT can benefit environmental issues broadly in two forms Personal & Institutional

  12. Personal and Institutional IT Systems • Personal IT Systems enables to broaden the horizon of time, space and complexity to think and act in the way to respond effectively to environmental issues (individuals/groups level) • Institutional IT systems is same as personal but broaden the horizons of understanding and action for large-scale organizations (corporations, governments, universities etc)

  13. Human-Centered Computing (HCC) • Humansarethemostimportantelements in developingcomputingsystems • Extended HCC focus on largerscale of Horizons herecomesGreen IT

  15. Key values of the ”EHCC” • Provide a structureto analyzepossibleresponses to Environmentalproblems • Help to discoverenvironmentalimpacts of the IT systems • Provideorganizingstructurethroughcomparingdifferenttechnologies

  16. Questions • Based on whatfacts HCC is discussed? And does it downplaythesurvival of otherspecies? • How can IT beused in broadeningthe HCC approach? • Whywouldnon-industrializednationsstrive to avoidenvironemtnalproblemstheyarenotthecause of?
