Development, production and installation of investments in climate action, sustainable energy and Cleantech customarily demand a considerable amount of capital. Sustainable development is thus also dependent to a significant extent on financial resources themselves, as well as on their composition and local conditions. In many countries, the markets for such financial products are currently not sufficiently developed. In addition, these markets are so extremely dynamic that continuous exchange of knowledge between the various groups of stakeholders is essential. adelphi supports its contractors with organisation and capacity building, focusing its work on the issues of sustainable investments, green lines of credit, and the financing of projects on topics such as climate, innovation, renewable energies and energy efficiency.
