The German government, through its various ministries and agencies, plays a significant role in infrastructure development and investment within Germany and internationally. Its investment focus spans various sectors, including transport, energy, digital infrastructure, and social infrastructure, with a strong emphasis on sustainability and energy transition.

The Danish government is a sovereign entity responsible for national policy, regulation, and significant public investment in Denmark's infrastructure. It drives major projects in transport, energy transition (especially offshore wind and green hydrogen), and digital connectivity, often through state-owned enterprises and public-private partnerships.
