1. Hardware & Software Developments
Environment

2. Environment video conferencing wireless technologies
reduces the need to travel = less CO2 emissions
wireless technologies
less need for cables which can be unsightly (& safety risk?)
mobile systems require less power than desktop systems
unsightly cables & masts that can be seen and ruin landscapes.
mobile phone networks have potential health risks (?)
sensors used to monitor the environment
Modelling software can forecast what is going to happen
polar ice, ocean currents, desertification, deforestation, ozone layer …..
help to prevent serious damage, injury, loss of life …..
weather could be predicted
computer modelling based on rules
gases emitted into atmosphere to change the pattern of undesirable weather?
farmers can use sensors that detect rainfall
less water required (automated sprinklers when needed)

3. Environment Energy usage Electronic Waste
increased use of ICT systems has higher energy costs
electricity needs to be generated
Electronic Waste
new technologies = throw away older hardware
landfill dumping (> 1 million tonnes per year)
poisonous components of hardware (lead, arsenic, cadmium …) leach into water
Raw materials & sustainability
new hardware requires manufacturing
limited supply of raw materials
need to recycle components
Building management
IT systems generate heat & require cooling
energy requirements for air conditioning
computer-controlled environment systems reduce energy use

4. Environment Health & Safety working environment?
long-term effect of use of ICT at work & for leisure
back-ache, eye-strain, RSI ….
