Optimization

The second main principle of approaches that use ICT to enable emissions savings is optimization, which is a very general term that leaves room for interpretation. To clarify this term, optimization makes things more efficient regarding to energy consumption or the usage of other resources. In opposition to the concept of dematerialization, the focus of the principle of optimization is not the replacement of things by ICT. In this case, ICT enables improvements in energy consumption and emissions reductions by making units or processes more efficient. Therefore, in the taxonomy the optimization potential of ICT is split up into unit efficiency and the optimization of processes. The first taxon groups together approaches which improve the energy efficiency of machines, production units, devices or any other physical object. Process optimization is divided into two main concepts, where automation is one and coordination the other. Automation makes use of technology to execute tasks without the need for manpower. Alongside production processes this principle is also used in lighting systems in buildings for example. The taxon coordination stands for improved coordination of processes and work flows by using information and communication technology. This involves computer applications used to optimize transport routes, as well as smart grids developed to coordinate energy supply more efficiently.

Optimization can also be considered as making things smart, as ICT enables to build smart motor systems and to improve energy efficiency in buildings and transport by smart buildings and smart logistics [1]. One the one hand the term smart stands for a kind of intelligence that inheres these improved units or processes, on the other hand The Climate Group defines the actions the ICT sector can take to improve the global emissions situation by the five letters of SMART [2]:

• Standardization of how energy consumption and information about emissions can be traced and made accessible throughout different processes in economy. 
• Monitoring of energy consumption and emissions in real time. 
• Accountability for energy consumption and emissions should be established beside other business priorities. This can be achieved by the application of network tools. 
• Rethinking about how we should live, learn, play and work in a low carbon society, enabled by ICT as an information platform, which can also help working together to gain efficiency improvements. 
• Transformation of the economy will happen if the enabling effect of ICT can be turned to account. 

This assessment of The Climate Group concerning the optimization potential of ICT suggests that Information Technology can support and enable a transformation process to a low carbon economy and society in a great extent. But this implies the acceptance and commitment of other economic sectors and governments.
