ICNIRP (International Commission on Non-Ionizing Radiation Protection)

ICNIRP is an international association of scientists who are researching the effect of non-ionizing radiation on people's health. The association, headquartered in Germany, is housed within the German Federal Authority for Radiation Protection but is legally independent from the latter organization.

ICT (Information and Communication Technology)


IDW PS 821

The IDW PS 821  standard of the Institute of Public Auditors in Germany ensures that report contents correspond to the information needs of the target groups. The reporting organization can base its reporting on the criteria of the GRI, OECD or ILO or on its own list of criteria. These criteria must be classified as suitable by the auditor and be used to test completeness.

ILO (International Labour Organization)

ILO was founded in 1919 and since 1946 has been a special United Nations organization with its main office in Geneva. 182 states around the world are ILO members. They delegate government representatives and representatives of employer and employee interests. The object of ILO is to improve work and living conditions of all people in order to secure world peace. To this end, legally binding treaties and conventions as well as work and social standards have been drawn up. The member states report regularly to the ILO on implementation of the treaties, and on the status of their national legislation relating to industrial law and industrial safety legislation. On this basis, the ILO creates the Global 100 list of the world's most sustainable companies from the 1,800 corporate groups listed on the MSCI World index.


Immissions  are noises, tremors, air pollution, heat, radiation and similar environmental effects that impact people, animals, plants or objects.


The Swiss rating agency uses its own sustainability ratings to create investment universes, e.g. the „Futura Global Stock" fund issued by Switzerland's Raiffeisen banks.

Internet /Intranet

The Internet is a worldwide Internet Protocol ( IP )-based computer network that has no central network management. By contrast, intranets are managed IP  networks that can be accessed only by specific user groups.


IP  stands for Internet Protocol and is a data encryption system for data exchange over the Internet.

IP adress

Each computer that is connected to the Internet has a clearly identifiable, numeric address, the IP  address, comprising four sequences of digits that are separated by periods, e.g.: (example: T-Online). Static IP  addresses enable the same computer to be contacted under the same address at any time (e.g., by a Web server). Dynamic IP  addresses are allocated for instance to T-Online customers dialing up to the Internet. They receive an unoccupied IP  address which will not be the same every time.

IP radio relay technology

IP  radio relay technology is a transmission system for transmitting data across large distances via radio relay. Data is transmitted in separate packets using the Internet Protocol (IP ). In radio relay, special directional antennas are used to focus radio waves and transmit them in a certain direction, and to receive them accordingly.

ISAE 3000

The ISAE 3000  standard of the International Federation of Accountants provides an international framework for testing non-financial information and can therefore also be used for sustainability reports. The principles of materiality, relevance and honesty are applied to the object under test, which is specified by the customer and the auditor in advance.

ISDN (Integrated Services Digital Network)

ISDN integrates telecommunications services such as telephone, fax and data communications in a single network. ISDN digitizes the data, which improves transmission quality, enhances transmission speed compared to the standard analog transmission system, and enables packet-switched transmission.

ISO 14001

The international environmental management standard ISO 14001  defines requirements that are accepted worldwide for environmental management systems. It focuses on a continual improvement process in the implementation of green goals in business enterprises and other institutions. Based on ISO 14001 , environmental management systems can be certified by independent environmental auditors.

The following Group companies were certified under Telekom's ISO 14001  umbrella certificate at the end of February 2012:

  • OTE
  • Slovak Telekom
  • Magyar Telekom
  • PTC
  • Telekom Deutschland
  • T-Mobile Austria
  • T-HT Hrvatski Telekom
  • T-Mobile UK
  • Makedonski Telekom
  • T-Mobile Czech Republic
  • T-Mobile Netherlands
  • T-Systems Deutschland
  • T-Systems Czech Republic
  • T-Systems Iberia
  • IT Services Hungary
  • T-Systems Austria
  • DeTeFleetServices
ISO 16001

This standard describes the requirements for an energy management system which aims to enable the company to systematically and continually reduce energy consumption while taking into consideration legal framework conditions.

In principle, EN 16001:2009 is based on the environmental management system standard ISO 14001 , making it very easy to integrate into it. A joint introduction of both systems is therefore very sensible and advisable.

ISO 50001

ISO 50001  is a global standard for operation of energy management systems at companies.

ISO 9001

ISO 9001  is an international standard that specifies minimum standards according to which processes must be configured in a company. This ensures that customers receive the expected quality. ISO 9001  concerns the quality and reliability of services and deliveries but is not a product certification.

imug (imug (EIRIS))

During analysis of CR performance by imug/EIRIS, corporate data for each individual criterion is assessed on different scales, usually covering five grades. Investors can map the results of evaluation of quality and quantity in the EIRIS Portfolio Manager, giving individual weighting to individual criteria. It is therefore impossible to make a general overall assessment of CR performance since this depends on the individually selected assessment framework and the investor's individual choice of criteria.
