The promotion of renewable energies is essential for sustainable development. It is also an important part of national plans for climate protection and adaptation (Nationally Determined Contributions – NDCs), which the parties to the UNFCCC committed to implementing when they ratified the Paris Climate Agreement in 2015. However, a “yes” to wind and solar energy does not only benefit the climate: prioritizing renewables is usually accompanied by a series of positive additional effects, known as co-benefits. These include, for example, better air quality, the protection of natural resources, the promotion of technological development, greater energy security, better access to electricity and the creation of future-proof jobs. Countries with rapidly increasing energy requirements such as Turkey, India, Kenya, South Africa and Vietnam will be faced with energy and climate policy decisions in the coming years that will influence their energy policy future for decades to come. In the national discussions on future energy policies in these partner countries, co-benefits are important arguments for the decision in favor of more renewable energies. They can therefore make a positive contribution to pursuing a sustainable and climate-friendly development path. However, it is very important that the co-benefits do not remain abstract and general, but that they are individually tailored to the political and social needs in the respective countries. This is where the COBENEFITS project came in by providing ministries, authorities and non-governmental organizations in the project countries with “tailor-made” advice on co-benefits selected by local decision-makers. Together with national knowledge partners, the project quantified country-specific co-benefits of climate policies, with a focus on opportunities through sustainable energy in the electricity sector. After completing the studies, UfU worked with stakeholders in the partner countries to develop proposals for measures – known as enabling policies – that support the best possible and fairest use of the co-benefits. In addition, the capacities of political decision-makers, knowledge partners and multipliers were strengthened through political dialog rounds, training materials, online courses, classroom training and networking. As a result, they are increasingly in a position to successfully exploit the positive social and economic side effects of climate protection measures.
