“Green IT’ is an oxymoron, until you consider the use of IT to ‘green’ business and society.”
~Simon Mingay, Gartner Research
Outline for the first global IT strategy for CO2 reductions (PDF)
ICT GHG Emissions: Est. 2%
Emissions from other sources: Est. 98%
*Figures are estimates of annual global emission.*
At NC State, information and communication technologies (ICT) may account for about 20% of the campus electricity-related GHG emissions.
The Hillsborough Building and Admin III are the largest consumers of electricity on campus (data center locations)!
Tech savvy and Green savvy – You can be both!
|Average office desktop computer & LCD monitor =
|If running 10 hours (1 kWh) at NC State =||$.076 e. bill
~1.2 pounds CO2
|Annually, if busy 8 hours per workday, power management =
(Note: More than twice these numbers if never turned off
and power management disabled)
|~$63.30 e. bill
~252 pounds CO2
|NC State owns and operates more than
15,000 office computers =
(This does not include student computers,
data centers, data network, telecom, printers, etc.)~$949,500 e. bill
~3,752,400 lbs. CO2
~1,702.06 MTe CO2 (Estimates based on EU Energy Star Energy Calculator,
EPA Energy Profiler)
On the other hand, carbon reductions are enabled by ICT
- Virtual travel, global communication
- Distance learning
- Telework, virtual meetings
- “Dematerialization” and e-business efficiencies
- SMART buildings, SMART grid, energy management
- Energy efficiency in Industry
- Advanced R & D for low-carbon solutions

“As a whole, ICT is best viewed as a catalyst that can speed up current negative trends, or alternatively contribute to a shift towards sustainable development . . . “
Why should we care?
(beyond concern about a sustainable future!)
- NC State University Sustainability initiatives
- President’s Climate Commitment, signed 2008
- Senate Bill 668 / Session Law 2007-546 – conservation of energy and water use in state, university and community college buildings
- Finances (e.g., Facilities may begin billing departments for electricity.)
- Outreach & Education: Green IT Tips
- In classrooms
- In computer labs
- In offices
- In Data Centers and server rooms
- Purchasing (EPEAT and Energy Star; packaging and waste reduction)
- Reuse and e-cycling
“The most common ES initiatives under way in central IT are server consolidation and virtualization, centralization
of storage, recycling of e-waste, and minimizing growth in electrical energy use.”
Can we integrate energy and sustainability considerations into service planning and reporting?
- Miles not traveled?
- Pages not printed?
- Energy saved?
