The non-availability of reliable and updated quality information and knowledge is a major barrier for the uptake of sustainable energy and climate technology (SECTs) markets in developing countries. Particularly, in least developed countries (LDCs) and small island developing states (SIDS) domestic key stakeholders (e.g. policy makers, entrepreneurs, project developers, suppliers) have difficulties to access information on latest technology innovations, lessons learned, as well as practical templates and tools. Simultaneously, for international partners it is difficult to access knowledge on the specific conditions and latest developments in these countries. In this context, the GN-SEC centers agreed to establish a joint knowledge platform which will be expanded throughout the next years. The platform will bring together the generated knowledge by all GN-SEC centers.
