Controversial Views on ICT vs. Sustainability
 ICT has been regarded as part of the problem
 Polluting the environment with e-waste and harmful
substances
 Accelerating climate change by increasing the carbon
footprint from growing aggregate ICT-related energyconsumption
 Inspiring new usage scenarios that lack social responsibility
 ICT has always provided business- and economic benefit by
increased productivity and process-efficiency
 Overall productivity of most industrial production factors
depends on enablement by ICT
 Management processes in business and economy are relying
on transparency that are enabled by ICT
 But quantification of cost and benefit of ICT in relation to
sustainability has been vague

Climate Change is the Big Challenge
 Limiting global warming at the level of 2 0C
1)
•Implies a limit of additional CO2-emissions of approx. 700 Gt
in total (eternal) (global emissions are now at approx. 32 Gt
p.a., increasing)
•Is, for economic reasons, only compatible with descend-paths
that reverse the trend of increase before 2015
•and is therefore NOT a problem of future generations but is a
problem that can only be resolved today – by THIS generation
 Alternatives for the descend-phase
35%
60%
5%
1)
2)
•„less CO2 in consumed energy”,
Replacement of fossile fuels
•”less energy in material welfare”
Improvement of energy-efficiency
•“less welfare“
2)
(Reduction of (irrational) luxury))
Since the beginning industrialization - increase of average temperature since 1900 amounts to approx. 0.7 0C

The Different Faces of Green ICT
 Environmental optimization of ICT products
 Hazardous materials / Resource-efficiency / Waste (Recycling)
 Product-lifecycle CO2-aspects (PCF, LCA)
 Energy-efficiency / CO2-reduction in ICT
 Hardware-aspects and systems-management
 ICT-Concepts / -architectures (virtualization)
 Efficiency-aspects in the data center facility
 Energy-efficiency / CO2-reduction by ICT
 Direct potentials for power-grids / buildings / traffic, indirect
effects by factor-substitution in business processes (materials,
travel, space)
 Assessment methods to quantify the enabling effects of ICT
 Transparency and control by applying “carbon management“

Server racks
(1) Highly accurate temperature measurement
more than 10,000 points* capable by using
a single optical fiber at a time.
(2) Reduced/no EMI effect to server system
due to use of optical signals.
(3) Realtime sensing of abnormal temperature
rising of server and air conditioning system
is capable; contributes to fire accident
prevention.

Enabling Energy-Efficiency by ICT
 In recent years this discussion has been dominated by
“Smart Topics”
 Direct potentials for power-grids / building-automation / trafficcontrol have been the focus, now moving to the more general
“Smart Cities”
 However, the ICT-related potentials to increase energy-efficiency
reach far beyond specific vertical application that might seem
immediately appealing
 Indirect effects by factor-substitution in business processes
(materials, travel, space) are significant, but do not constitute the
primary business case for innovation
 Unbiased assessment methodology to quantify effects
in projects is a prerequisite for rational decisions
 Management requires transparency
 Energy reporting is a prerequisite for identifying significance of
efficiency improvement potentials

Implemented Environmental ICT Solutions
 Method for CO2 impact assessment published in the Fujitsu
Scientific & Technical Journal (FSTJ), vol 45(1), 2009
http://www.fujitsu.com/downloads/MAG/vol451/paper12.pdf
 More than 240 solutions / cases have been assessed,
grouped in 14 categories
 These applications constitute the basis for the CO2
reduction commitments “BY IT” of Fujitsu
 Efforts to establish the assessment methodology through
backing by industry consortia standardization bodies
are progressing.
 FUJITSU has made significant contributions to the ITU-T
standards on Green ICT assessment (L.1410, L.1430)

Transparency on Environmental Data
 Managing CO2-reduction and energy-saving requires
transparency on pollution, consumption and cost at
the overall company level
 Environmental management systems (EMS) can enable
cross-company reporting-processes to provide such
data
 for standardized auditable reports, compliant to legal
requirements
 as a basis for environmentally conscious business planning
 Responding to upcoming new energy legislation in all
EU-27 countries, FUJITSU is now globalizing its
Japanese EMS to become an SaaS offering
 with NLS of major European languages
 compliant with national laws
 addressing different levels of organizational complexity
