Sustainable ICT
The net effect on the environment of the use of information and communication
technology (ICT) is by no means fully clarified. ICT products and services can
represent an environmental impact in terms of the way in which they affect the
environment today. The aim must be to reduce the need for raw materials and
energy consumption whilst increasing the degree of recycling of ICT products.
Moreover, there is considerable potential for ICT services to contribute to a more
sustainable development in the years to come. We can for example replace
materials and transportation needs with computer based services ("Bits instead of
atoms"). The presupposition is that consciousness, fundamental conditions and
methods which stimulate this kind of development are in existence.
ICT and environmental challenges in general
ICT products and services are electronic products which show considerable
variation as regards production conditions, areas of use and environmental
impact, and include everything from communications satellites to Tamagotchi. As
a result of the considerable spread of ICT services and products in recent years,
attention has been focused on several aspects of information and communications
technology.
Increased interest has also been shown in the environmental challenges
connected with the manufacture, use, re-use and disposal of ICT products, both
in Norway and in the rest of the world. As regards knowledge of the
environmental impacts of ICT products and services, a certain amount of know-
how exists nationally and internationally, but in relation to the majority of ICT
services, this is inadequate and too fragmentary to enable any clear conclusion to
be drawn. To sum up, the most important environmental impacts with regard to
ICT products and services, in all phases of their life-cycle, can be considered to
be:
Consumption of large amounts of raw materials and chemicals in
manufacture
The results are a large demand for raw materials as well as considerable
emissions to air, water and soil.
A strongly growing energy requirement
Strong growth in the number of products/units reduces the effect of the
reduction in the amount of energy used by each unit.
Inadequate re-use and recycling
Only a modest proportion of equipment and materials is re-used or
recycled.
In the table below, an attempt has been made to provide a very rough estimate
of the possible environmental impacts of different ICT services, making certain
specific assumptions.

ICT and transport reduction
Global statistics show a steep increase in both passenger and goods transport,
and particularly in the use of those means of transport which place the greatest
demands on resources and the environment (road and air transport).
Transport, both of passengers and goods, involves considerable environmental
drawbacks connected with energy consumption, emissions to the air, climate
change, raw material consumption, etc. Both the authorities and the business
community face considerable challenges as regards reducing the negative effects
of increased transport and exploiting the potential of new technology.
Various ICT services can represent a substitute for transport, especially in the
major urban areas. ICT supplements and reinforces, rather than replacing
physical transport. Some examples are:
Intelligent transport systems (ITS)
which can contribute to a reduction in the environmental drawbacks
connected with traffic.
Teleworking, distance learning and video conferences are initiatives which
can contribute to a reduction in traffic density, possibly reducing the rush
hour problem.
Investments in electronic infrastructure It is unclear to what degree
investments in electronic infrastructure can be an alternative or
supplement to investments in physical infrastructure (roads).
ICT and reduction in raw materials (dematerialisation)
Possibilities for transforming physical products into services are a challenge with
regard to ICT and the environment. Dematerialisation through the use of
ecological design, industrial ecology and recycling of resources will be a
contribution in the work towards achieving Factor 10 (a 90% reduction in raw
material requirements). Life-cycle analyses (LCA) are also an important tool for
achieving high environmental efficiency.
In the production pattern of the future, a number of today's products will be
replaced by Internet based products or electronic products. For example, a video
player can be replaced by video viewed on the Internet.
In the future, value creation will be connected to a higher degree to service and
maintenance of the product, and less to its actual manufacture. In addition, the
need for new raw materials will be reduced through the increased use of recycled
materials and by "tailoring" the product for the individual consumer.
Some examples are:
The environmental effect of Internet based answering services -
physical product and network service
Telia has carried out a life cycle analysis (LCA) of its Internet based answering
service, (Telesvar), compared with a physical answering machine. The way in
which the service is provided makes no difference to the consumer, but the study
shows that there is a big difference in the environmental impact of the two types.

Environmental savings resulting from digital radiography
A Swedish study carried out in 1999 shows that the change to digital radiography
equipment in hospitals in Stockholm has given the following annual
environmental savings:
Reduction in consumption of film for X-rays: 230 000 m2
Reduction in consumption of X-ray contrast fluid: 100 000 litres
Reduction in consumption of photographic processing chemicals: 120 000
litres
In addition, digital radiography subjects both patient and personnel to lower
radiation doses.
Individually adapted mass production (as at Dell computers)
just in time (reduces the need for storage space - hence reduced energy
and raw material consumption)
just for you (individually adapted textbooks)
just enough (products adapted to individual businesses)
Re-use
use of surplus materials (as by the company Inverse AS, which makes use
of the Internet in its trade in surplus material).
increase the percentage of re-useable materials
avoid random spreading and disposal of chemicals representing a health or
environmental hazard
Fewer shops and department stores
smaller area occupied by new buildings
lower consumption of natural resources and energy in building and
operation
Other examples
"from books to bytes" (Internet versions of telephone directories, novels,
etc.)
from CD to MP3 (downloading music from the Internet)
from photographs to electronic images
from cheques to smart cards
marketing by means of electronic images on PC and TV instead of
packaging and display.
Case: Non-sustainable material consumption
In connection with life-cycle analyses of the manufacture of PCs
carried out by Wuppertal Institute in 1997/1998, the
consumption of raw materials in the production of 486 PCs
(each weighing 22 kg) was studied.
The following results were obtained:
-The consumption of raw materials per PC was between 16 and
19 tonnes (depending on the degree of utilisation), and the
conclusion was that only about 0.1% of the physical mass which
is involved in the manufacture of a PC is used in the actual
product. A similar study carried out by IBM concluded with a
figure of 1.4%.
The studies emphasise the following central challenges:
The material consumption in the manufacture of PCs
The need for ecodesign and incentives which make
recycling worthwhile.
ICT products and sustainable development
It is important to emphasise that in spite of the major challenges faced by the
ICT industry in the environmental field, the ICT services also have considerable
potential to be an important contributor in relation to sustainable development.
Sustainable development is an important, international political objective. The
table below shows some of the most important elements in sustainable
development and the way in which ICT services can contribute to the
achievement of objectives with respect to these elements.

ICT services and the potential for environmental improvement?
The International Environmental Institute at Lund University in Sweden has
carried out a comparison of some of the most frequently used ICT services in
terms of their potential for environmental improvement (Arnfalk, 1998).
The following criteria were used:
Potential
The ICT service's potential for affecting the environment, based on
possible positive effects.
Realistic result
An assessment of the ICT service's actual and probable environmental
impact, including both positive and negative environmental aspects as well
as any possible hindrances
Association and measurability
The positive environmental impact must be directly associated with the
service and shall be measurable.
ICT products and Potential Realistic Association and TOTAL
services result measurability
E-business (B2B) 3 2 3 8
Teleworking 3 3 2 8
E-mail 3 2 2.5 7.5
E-learning 2.5 2 2.5 7

Telephone calls 1.5 2 1 4.5
Amongst the ICT services which were studied, the results show that teleworking
and e-business are considered to have the greatest potential for environmental
improvement. The environmental potential of the following additional ICT services
has also been assessed:
Transport telematics
Telemedicine
Electronic conferences
Electronic marketing
Print, music and video on demand
The environmental potential of these is considered to be lower than for the
services encompassed by the table above.
The use of ICT as an environmental tool
A range of ICT services can represent important tools in the work of reducing
environmental impact.
For example, environmental monitoring can provide research establishments with
increasingly better tools for assessing the environmental situation, whilst public
administration acquires knowledge which can form the basis for shaping
important fundamental conditions and agencies.
The following environmental tools are of interest:
environmental monitoring by satellite
remote control of energy consumption
route planning/logistics
correlation of environmental data
dissemination of information (Internet), etc.
