Scope
 The scope of FG Deliverable 1 was to create a common framework on
which to build methodology, recognize gaps and define metrics to
reach the goals of the Focus Group :
 Understand and mitigate negative impact of ICT on climate change
(raw material extraction, production, use phase, end of life),
increasing in particular the efficiency of equipment, networks and
organisations.
 Understand and encourage positive impact (for instance travel
substitution, product substitution, smart buildings… ) : reducing
GHG emissions
 Understand and encourage measurement and monitoring of
climate change impacts

Some positive effects identified
Category
Effects
Consumption of goods
By reducing goods consumption (consumption of paper etc.), energy consumption related to
goods production and disposal as well as waste generation can be reduced.
Power consumption /
energy consumption
By enhancing the efficiency of power and energy use to reduce consumption, energy
consumption related to power generation, power transmission, etc. can be reduced.
Movement of people
By reducing the movement of people, energy consumption required for transportation means
can be reduced.
Movement of goods
By reducing the movement of goods, energy consumption required for transportation means
can be reduced.
Improved efficiency of office space
By using office space efficiently, power consumption for lighting, air conditioning, etc. can be
reduced, thus reducing energy consumption.
Storage of goods
By reducing storage space of goods, power consumption for lighting, air conditioning, etc. can
be reduced, thus reducing energy consumption.
Improved work efficiency
By enhancing work efficiency, resource and energy consumption can be reduced.
Waste
By reducing waste emissions, energy consumption required for environmental preservation as
well as for waste disposal etc. can be reduced.
Rebound effect
For some services brought by ICT such as telework or
videoconferencing, the time gained for an end-user when
using the telecom service may cause some additional usages
– telecom or physical - which are difficult to track.
These additional usages can be defined as “rebound effect”.
There is ongoing research on this topic.
