2.1.1 ICT's two-fold role
Nowadays, there are few things in our lives that are not created, controlled, or popularized by information and communication technology (ICT). It shapes our future, and yet threatens it. According to ITU (International Telecommunication Union), ICT is estimated to contribute around 2-2.5 per cent of global greenhouse gas (GHG) emissions. These percentages are likely to grow as ICT become more widely available. While being part of the problem, ICT is also a major linchpin in efforts to fight climate change and serve as a potent, cross-cutting tool to limit and ultimately reduce GHG emissions and save energy across economic and social sectors, in particular by the introduction and development of more energy efficient devices, applications and networks, as well as their environmentally sound disposal. Hence, ICT is part of the problem as well as part of the solution to climate change.
As part of the problem:
- Internet - 5.3% of world's energy consumption
- Contributes around 2-2.5 per cent of global greenhouse gas (GHG) emissions.
As part of the solution:
- Monitoring climate change
- Data analysis & climate modeling
- Emergency services & disaster relief
- Travel substitution
- Transport management systems
- Sensor networks and process control (e.g. switching off unnecessary devices and production on-demand.)
