Support for the UN Climate Technology Centre & Network – 2020-2022 The Climate Technology Centre and Network (CTCN), headquartered in UN City Copenhagen, is the implementation arm of the Technology Mechanism of the United Nations Framework Convention on Climate Change (UNFCCC). The CTCN promotes accelerated technology development and transfer, as well as strengthened policy and regulatory environments, at the request of developing countries as they seek to fulfil their Paris Agreement and Sustainable Development Goals. The Centre has served over 100 countries since its launch in the fall of 2013, providing targeted mitigation and adaptation interventions that enable countries to make progress in their transition to more climate resilient, low carbon economies.
