About Us


Who we are

The Climate Technology Centre and Network (CTCN) is the operational arm of the UNFCCC Technology Mechanism and it is hosted and managed by UNEP in collaboration with UNIDO and with the support of 11 Centres of Excellence located in developing and developed countries:

CTCN structure

The Climate Technology Centre (CTC) is responsible for overall coordination, development of the Climate Technology Network (CTN), and liaison with National Designated Entities (NDEs) and is backed by the Consortium Partners.

UNEP, UNIDO, and the Consortium Partners have breadth and depth of expertise in:

  • adaptation and mitigation, along all steps of the technology cycle
  • specific technology subject areas
  • geographic understanding and language capabilities
  • expertise in knowledge management
  • network development and management

Delivery of CTCN services is facilitated through a wide and diverse Network of international, regional and national institutions that can respond effectively and efficiently to countries' requests. The network is currently being established. For more information, click here

The CTCN is guided by an Advisory Board and it is located in Copenhagen, Denmark.

What we do

The Climate Technology Centre and Network (CTCN) promotes accelerated, diversified and scaled-up transfer of environmentally sound technologies for climate change mitigation and adaptation, in developing countries, in line with their sustainable development priorities. As defined by the Intergovernmental Panel on Climate Change (IPCC) climate technologies cover any piece of equipment, technique, practical knowledge or skills for performing a particular activity that can be used to face climate change.

Our mission

To stimulate technology cooperation and enhance the development and transfer of technologies to developing country parties at their request.

Our main functions

  • We manage requests from developing country NDEs and deliver responses
  • We foster collaboration and access to information and knowledge to accelerate climate technology transfer
  • We strengthen networks, partnerships and capacity building for climate technology transfer

How we work

  • Country-driven: As the operational arm of the UNFCCC Technology Mechanism, the CTCN provides technical assistance to developing countries at their request that supports the transfer of climate technologies.
  • Responsive: The CTCN provides high quality technical assistance quickly and at no cost for the requesting country through its Consortium Partners or the Climate Technology Network.
  • Capacity building: The CTCN works with national stakeholders to build or enhance endogenous capacities.
  • Collaborative: The CTCN works with stakeholders engaged in a wide range of activities related to climate technologies with the aim of facilitating south-south, north-south, and triangular collaboration and cooperation.
  • Catalyser: The CTCN builds on previous work carried out in the countries and creates links with other initiatives, in order to back up, complete and speed-up the transfer of climate technologies to developing countries.


Financial support is being made from various donors to support the work of the CTCN, including from the governments of:Canada, Denmark, Germany, Japan, Norway, Switzerland, United States and the European Commission.
