The UNEP - DTIE International Environmental Technology Centre
Established in April 1994, the International Environmental Technology Centre (IETC) is an
integral part of the Division of Technology, Industry and Economics (DTIE) of the United Nations
Environment Programme (UNEP). It has offices at two locations in Japan - Osaka and Shiga.
The Centre’s main function is to promote the application of Environmentally Sound Technologies
(ESTs) in developing countries and countries with economies in transition. IETC pays specific
attention to urban problems, such as sewage, air pollution, solid waste, noise, and to the
management of fresh water basins.
IETC is supported in its operations by two Japanese foundations: The Global Environment Centre
Foundation (GEC), which is based in Osaka and handles urban environmental problems; and the
International Lake Environment Committee Foundation (ILEC), which is located in Shiga Prefecture
and contributes accumulated knowledge on sustainable management of fresh water resources.
IETC’s mandate is based on Agenda 21, which came out of the UNCED process. Consequently
IETC pursues a result-oriented work plan revolving around three issues, namely: (1) Improving
access to information on ESTs; (2) Fostering technology cooperation, partnerships, adoption
and use of ESTs; and (3) Building endogenous capacity.
IETC has secured specific results that have established it as a Centre of Excellence in its areas of
speciality. Its products include: an overview on existing information sources for ESTs; a database
of information on ESTs; a regular newsletter, a technical publication series and other media
materials creating public awareness and disseminating information on ESTs; Local Agenda 21
documents developed for selected cities in collaboration with the UNCHS (Habitat)/UNEP
Sustainable Cities Programme (SCP); advisory services; Action Plans for sustainable management
of selected lake/reservoir basins; training needs assessment surveys in the field of decisionmaking
on technology transfer and management of ESTs; design and implementation of pilot
training programmes for adoption, application and operation of ESTs; training materials for
technology management of large cities and fresh water basins; and others.
The Centre coordinates its activities with substantive organisations within the UN system. IETC
also seeks partnerships with international and bilateral finance institutions, technical assistance
organisations, the private, academic and non-governmental sectors, foundations and corporations.
