About CTCN

The Climate Technology Centre and Network (CTCN) facilitates the connection between countries and climate technology solutions, expediting development and technology transfers for low-carbon and climate-resilient initiatives at the demand of developing countries. Positioned uniquely within the global climate action landscape, the CTCN serves as a vital link between all stakeholders, catalyzing collaborative efforts. It identifies and delivers a diverse portfolio of technology solutions, alongside offering capacity building and tailored advisory services on policy, legal, and regulatory frameworks to meet the specific requirements of individual countries. Leveraging the expertise of a global network comprising technology firms and institutions, the CTCN paves the way for national strategies, regional market aggregation, and the mitigation of investment risks, both in the public and private sectors. The focus lies on achieving transformative impacts and scaling up through national innovation systems and digitalization across five key areas: the Water-Energy-Food nexus, Buildings and Infrastructure, Sustainable Mobility, Energy Systems, and Business and Industry.

Design guidelines

The Climate Technology Centre and Network (CTCN) strives to stimulate collaboration on climate technology transfer and therefore encourages its partners to engage with the Centre in relevant capacity building, knowledge management, and technical assistance activities.

In order to represent the Centre and Network, their services and collaborative activities accurately, the Centre has prepared guidelines to convey attributes and values, that underpin their mission. These guidelines are designed to ensure clarity and consistency in the use of the Climate Technology Centre and Network brand.


The Centre’s logo is available in different formats and is never shown in other colours. Please use the logo for all official documents related to the Centre’s technical assistance, event promotion (invitation letters, agenda, posters, banners, etc.), presentations, publications and web content.
