6.3 Description of dimensions and sub‐dimensions of KPIs

6.3.1 D1 ICT

D1 concentrates on ICT infrastructure, which is the basis for other ICT solutions and smart
sustainable promotions. The ICT infrastructure includes network and access (D1.1), services and
information platforms (D1.2), information security and privacy (D1.3), and Electromagnetic field
(D1.4).

D1.1 Network and access

Network and access refers to the network layer in the Open Systems Interconnection (OSI) model,
especially backbone and access networks, including optical broadband, wireless broadband and
broadcasting network.

D1.2 Services and information platforms

Services and information platforms refers to ICT services and equipment above the network layer,
including software services and private handsets.

D1.3 Information security and privacy

Information security and privacy refers to the security parts including privacy protection.

D1.4 Electromagnetic field

Application of exposure guidelines, consistent planning approval process and information for public
should be considered with respect to Electromagnetic fields.

6.3.2 D2 Environmental sustainability

D2 examines the ICT usage and impact on key environmental areas. It is classified into five
categories: air quality (D2.1), CO2 emissions (D2.2), energy (D2.3), indoor pollution (D2.4), and
water, soil and noise (D2.5).

D2.1 Air quality

This part looks into the quality of air which is an important area for consideration for many cities.

D2.2 CO2 emissions

This parts looks into the CO2‐e emissions of the city where “‐e” is “equivalent” and every other
greenhouse gases are converted into CO2.

D2.3 Energy
This part looks into the energy use of the city.

D2.4 Indoor pollution
This part is about indoor environment.

D2.5 Water, soil and noise

This part collects elements such as water quality and noise.
