Climate change is amongst the most formidable global challenges of the 21st century. Major efforts are still required in the mission of establishing a low-carbon and climate-resilient society. adelphi supports its clients in the most important areas in climate policy: mitigation, adaptation, technology and financing as well as security and stability. By means of consulting in international political processes, we seek to place new issues on the political agenda and to promote the development and implementation of climate mitigation campaigns. These issues include foreign policy initiatives in the field of climate diplomacy as well as the development of the major potential for solutions in cities and local authorities. We investigate the consequences of climate change, evaluate climate and energy policy instruments and develop action strategies and decision-making systems for adaptation processes. In recent years, we have developed expertise in consultancy and training in the fields of carbon trading and climate finance which are in demand throughout the world.
