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.
