The GIZ internal sector network TUEWAS (Transport, Environment, Energy and Water in Asia) was established in Bonn, Germany in 2002, as a platform for regional professional exchange and cooperation between GIZ experts in Asia and at head office. Currently, TUEWAS connects over 50 projects across 16 Asian countries in the field of transport, environment, energy and water.

In order to promote greater collaboration with similar thematic relevance, TUEWAS has set up joint work clusters with other networks in the region, namely Sector Network Natural Resources and Rural Development Asia (SNRD Asia and the Pacific) and Sector Network Governance Asia (SNGA). As a result, more than 150 individuals are actively involved and its Secretariat is located in Bangkok.

About GIZ

Owned by the German government and with operations around the globe, the Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH provides services in the field of international cooperation for sustainable development. Working on behalf of other public and private sector clients both in Germany and overseas, GIZ operates in more than 130 countries and employs approximately 17, 000 staff worldwide. These include the governments of other countries, the European Union, the United Nations, the Asian Development Bank, and other development organizations.

About Our Commissioning Agencies

The German Federal Ministry for Economic Cooperation and Development (BMZ) is GIZ’s main commissioning party which has been working closely together for more than 30 years. BMZ is one of two ministries representing GIZ’s sole shareholder, the Federal Republic of Germany, on GIZ’s Supervisory Board. The Ministry commissions GIZ to implement advisory projects that enhance the capacities of individuals, organizations and societies to improve their living conditions through efficient and sustainable use of resources in order to attain their goals.

The BMZ moreover builds up the guidelines and the central ideas on which German development policy is based. It devises long-term strategies for cooperation participation with the different players concerned and outlines the rules for actualizing that collaboration. These are the establishments for developing shared projects with partner countries and global development associations. When working on behalf of BMZ, GIZ also attach priority to ensuring that the projects can continue after funding from the German Government has ceased.

The Federal Ministry for the Environment, Nature Conservation, and Nuclear Safety (BMU) works closely with GIZ and commissions the company to implement various bilateral and regional projects and programmes, mainly within the scope of the International Climate Initiative (IKI). For the IKI projects, priority is given to the activities that support creating international climate protection architecture and promote innovative and transferable solutions that have an impact beyond the individual project. Since 2008, the International Climate Initiative (IKI) of the Federal Ministry for the Environment, Nature Conservation,  and Nuclear Safety has been financing projects as a part of Germany’s climate financing and funding commitments. These efforts provide various co-benefits, particularly the improvement of living conditions in partner countries.

GIZ also advises BMU on matters relating to the development of the International Renewable Energy Agency (IRENA), the expansion of global CO2 trading, the implementation of the Mediterranean Solar Plan, the assistance of the Ministry to secure EU and third-party funding.

The Federal Ministry for Economic Affairs and Energy (BMWi) is a cabinet-level ministry of the Federal Republic of Germany which is also a member of GIZ’s Supervisory Board. Cooperation between GIZ and BMWi focuses mainly on issues relating to the promotion of international trade fairs and exhibition programme. In this context, GIZ primarily helps establish an enabling environment in Germany’s markets abroad.

Additionally, GIZ implements projects and programmes within the framework of the Renewable Energies Export Initiative and is engaged in international manager training. It also facilitates bilateral energy dialogues; for example, in China and India, provides general advice on international energy issues, and helps to secure European Union funding for twinning projects or partnerships between public administrations. GIZ supports implementation of these projects, the Ministry hosts Germany’s National Contact Point for Twinning, which advises all the federal ministries on twinning issues and represents their interests in twinning matters to the European Commission on a joint basis.
