Green of IT (2%)
845 million TCO2
reduction effect
Green by IT (98%)
4.89 billion TCO2
reduction effect
- ‘Green of ICT’ influences only 2% of
global CO2 emission, while ‘Green by
ICT’ covers the other 98%
- ‘Green of IT’ can reduce 845 million
TCO2 worldwide, while ‘Green by IT’ can
lead to 4.89billion TCO2 reduction
globally
-’Green by IT’ is approximately 5 times
more effective than ‘Green of ICT’ in
terms of CO2 reduction
