This document discusses how information and communication technologies (ICT) can help make business and infrastructure more environmentally sustainable. It outlines how ICT manufacturing, operation, and disposal can be made greener through practices like low power consumption and increased recyclability. It also explains how ICT can enable greener built infrastructure through applications like smart grids, smart buildings, and smart logistics. Additionally, the document discusses how ICT can help assess ecosystems and environments, and how sociotechnical systems can encourage sustainable human behaviors through information and tools.

4. Greener IT – Manufacturing

Most of ICT manufacturing are adopting Green production.

Resource efficiency is main driver for all manufacturers.

Low power consumption, low heat, resource sharing…etc.


Estimated 6,000 Data centers in US in consumed 1,000,000,000 kWH in 2006.

Cooling is taking the highest share of energy.


In addition to power efficiency clean sources are also utilized.


Ability of product recycling.

Cost of disposing & recycling is added the total cost of ICT.

The rp5700 exceeds U.S. Energy Star 4.0 standards, 90% of its materials are
recyclable.


Sociotechnical identifies relation between technical & social aspects of an
organization.

Enabling, encouraging, and sustaining desired human behavior over the long
term to have noticeable impact on sustainability.

Information & tools can help individual & organization to make ongoing &
significant changes in response to certain circumstances.

What would happen if we provide more power cheaply?
