In this paper, the role of a matchmaker in transferring climate technologies to developing countries was explored from the perspective of open innovation. As the United Nations Framework Convention on Climate Change’s Technology Mechanism, the Climate Technology Centre and Network (CTCN) has strong convening power amongst the stakeholders who are responsible for climate actions in their country. Our research identified that the CTCN has successfully provided “4 openness” models (open network, open request for Technical Assistance, open technology transfer and finance, and open knowledge for the public) to global partners through its technical assistance (TA) services. Then, on the basis of previous empirical Technical Assistance data and network management a new open innovation model was proposed by considering the CTCN matchmaking activities with key stakeholders (innovation networks) during the climate technology transfer processes. This model explains that the role of the CTCN and innovation networks such as academia/research institutions, governments, and the private sector can be interpreted as outside-in innovation at the first technology outsourcing stage, coupled innovation at the second technology research, development, and demonstration (RD&D) stage, and inside-out innovation at the third technology diffusion stage. Moreover, further matchmaker’s approaches for supporting developing countries to establish a conducive and sustainable innovation system were suggested for the extension of our new model.

The 2030 Agenda for Sustainable Development and the Sustainable Development Goals (SDGs), the Paris Agreement, and a number of important agreements call on the United Nations (UN) to strengthen a relationship with the private sector to develop and transfer climate technology in global action on climate change. The Technology Mechanism (TM) is anchored in the UN Framework Convention on Climate Change as a key enabler for the attainment of the Goals of the Paris Agreement. The growing interest for collaboration with the private sector sets new ambitions for the UN Climate Technology Centre and Network (CTCN). The active engagement of the private sector is critical for successful technology transfer and successful innovation. This paper reviews and analyses the role of the private sector in facilitating technology transfer in CTCN’s Technical Assistance. Furthermore, the shared interest for partnership between the CTCN and the private sector was evaluated by analysing in-depths interviews with major CTCN stakeholders. Based upon this analysis, several recommendations are made on how to enhance public–private partnerships in order to strengthen private sector participation in climate technology transfer activities with a special focus on technology–push and market–pull innovation.

Technology Innovation has the potential to play a strategic role in improving the effectiveness and efficiency of national efforts to address climate change. The United Nations (UN) Climate Technology Centre and Network (CTCN) is mandated to support developing countries’ climate change responses through innovative technologies to achieve the goals of the Paris Agreement. In order to enhance the role of the CTCN as an innovation matchmaker, it is important to explore and leverage the implementation potential of new digital technologies and their transformational impact. Thus, in this research, to engage digitalization as an innovative tool with the environment, we first explored digitalization during the climate technology transfer processes by comprehensively reviewing CTCN Technical Assistance (Digitalization Technical Assistance, D-TA) activities in three climate sectors of risk prediction, policy decision making, and resource optimization. Then, by applying analytical methodologies of in-depth interviews with major digital-climate stakeholders and a staged model for technology innovation, we propose future strategies for enhancing the role of CTCN as an innovation matchmaker in the three digitalization cases of digital collection, digital analysis, and digital diffusion.

To tackle the global climate change issues, many countries have been interested in technology research, development, and demonstration (RD&D) during climate technology development and transfer processes in terms of technology innovation. According to our previous staged innovation model, technology RD&D is regarded as a crucial stage enabling the transition from technology-push to market-pull innovation. However, the strategic operation of RD&D during the climate technology transfer processes is still inactive. Thus, in the present work, we first elucidated innovative features by reviewing the RD&D activities during the climate technology transfer processes in terms of three elements of innovation: technology, market, and regulation. Moreover, innovative barriers to participating in the RD&D projects were identified by analyzing brief survey for various stakeholders from academia, private sectors, and governments. Based on both findings from case study and survey, new strategies were proposed for innovative RD&D facilitation, considering the interactions between the technology transfer matchmaker and Triple Helix during transferring climate technology.
