Following the decisions adopted at the 2012 Climate Change Conference in Rio de Janeiro, priority was given to economic concepts which can bring grown and environmental protection into harmony and ultimately lead to a green economy. The aim is that societies worldwide will profit from the opportunities offered by growing markets for sustainable products and services. However, before the transformation to a green economy can succeed, this concept must become a guiding political and economic principle. To this end, tangible spheres of activity, targets and implementation strategies will need to be established. adelphi supports decision-makers in Germany and globally in this multifaceted work, advising on the development of political strategies for subsectors of the economy. We also develop new instruments, design tailored sets of measures and assist in their implementation.
