Technologies are vital to building climate-resilient, low-carbon societies. Many essential technologies already exist — the challenge is to get them deployed where they are needed, and to build the enabling environments to support technology innovation, adaptation and scale-up. An overwhelming number of developing countries’ Nationally Determined Contributions (NDCs) under the Paris Agreement indicate a requirement for technology support and capacity building in order to achieve their commitments. To meet this need, the CTCN serves as a demand-driven and trusted partner, matching developing countriy needs for climate change-related equipment, methods, capacity development and policy advice with the world-class expertise of its Network and our collaborators.
