… Which Causes Worldwide Governments to Mitigate the Risk

Collectively the major economies of our world account for over 70% of the world’s emissions

The World is Moving to a Carbon Constrained Economy

Qantas will be hit with a penalty by the European Union because Australia does not have a price on carbon.

A carbon trade barrier!

Carbon Footprint of IT

Globally: 2% of all carbon emissions (~ 600 Mt CO2-e)Projected to rise to 3% in 2020 under BAU conditionsIn your company: IT’s contribution to the carbon footprint might be 40% Try to imagine IT’s footprint of cloud providers (Google, Amazon, Yahoo, FB, Twitter, IBM, HP, Microsoft, Apple, etc.)

What are the concerns:Embedded energy in devicesEnergy use in data centresEnergy use in endpoints (computers, laptops, etc.)Disposal after end-of-life

The Energy Use of a Typical Data Centre

Less than 15% of original source energy is used for the IT equipment within a data centre. Some

estimates say only 3%!

PUE = 1.07!

w w w . s u s t a i n a b l e b i z c o n s u l ti n g . c o m . a u | 1917 May 2011

PUE is important, but what about the Carbon Emissions?

Carbon Usage Effectiveness

CUE = EF x PUE

Ideal CUE value = 0.0 (no carbon emissions!)

Assumptions: 2,000 kwh energy consumed by data centre1,000 kwh energy consumed by IT equipment

CUE: 0.9 2 = 1.80 in NSW0.32 2 = 0.64 in TAS1.23 2 = 2.46 in VICPUE: 2,000

CUE becomes really relevant with a price on carbon…

Examples of Green IT Initiatives for Data Centres

Weed out low or nonperforming componentsPlug holes – no mixing of cool and warm airAdjust A/C settingsUse outside cooler air where you can (air-side economisation)Energy efficiency for IT equipment:

VirtualisationCloud ComputingOutsourcingServer specs: Performance per watt

Choose high-efficiency power suppliesData Centre design (A/C, location, etc.)Purchase renewable energy or generate on siteCo-gen or Tri-gen

IT As An Enabler

IT Has a Large Potential to Reduce Our Carbon Footprint

IT can lead to emission reductions 5x the size of the sector’s own footprint

Dematerialisation – moving bits instead of atoms (e.g. telecommuting, e-billing, e-commerce, e-government, digital music)Smart electricity grids (largest opportunity)Smart buildings (building design, heating, cooling, lighting, appliances)More efficient transport (route optimisation, RFID for asset tracking, GIS, GPS, etc.)Leaner industrial processes (VSDs)IT will help track and manage carbon footprints – Carbon Management Software
