Sustainable Development Goal 17 is about political, technological and economic cooperation across borders.

Political agreements regarding the green transition already exist at international, national, regional and local levels. Companies and knowledge institutions have long since announced they are ready and are already at work with the solutions. And citizens are ready, too. In fact, climate change is clearly the most important issue on the political agenda if you ask the Danes. But the transition to a sustainable society must be made even stronger. If we are to slow down climate change, we need to decide on a significant change of course at all levels of society – including in Denmark.

Gate 21 is working every day to bring together regions, municipalities, companies and knowledge institutions to find and test solutions for a thorough green transition. We have set our sights on making Greater Copenhagen the world’s leading region for green transition and growth.

We have created more than 100 green conversion projects with a total value of 900 million DKK. Within the projects, we have gathered all three regions in Greater Copenhagen (83 per cent of those municipalities located within Denmark), nine knowledge institutions and 41 companies.

Overall, this makes Gate 21 a unique partnership model and one of Denmark’s leading green organizations, in which we work together with our partners to develop concrete solutions for the whole of Denmark.


In Cleantech TIPP, municipalities cooperate with the business community to develop sustainable solutions that can help municipalities and, at the same time, ensure that green initiatives are not made at the expense of companies’ competitiveness.


As more of our power is generated from renewable energy sources, this raises the question of how we can best use green energy when there is a surplus of it. REEL answers that question.


Small businesses can play a major role in our journey towards the green transition. Carbon 20 has started developing and testing energy-saving measures in partnerships between municipalities and private companies.


Every day the average Dane travels 39 kilometers, and the vast majority of those kilometers are traveled by car. By making energy-efficient modes of transport more accessible, Formel M has succeeded in shifting Danish transport habits.


There is a great need to create new innovative green solutions within a number of complex areas – and this task cannot be solved by municipalities alone. As the UN’s Sustainable Development Goal 17 indicates, strong co-operation is needed in order to realize sustainable development.

Cleantech TIPP looks at how we can accelerate new solutions and drive sustainability through public-private innovation partnerships, so that public demand for sustainable initiatives is matched with innovative solutions from companies. This strengthens municipalities’ procurement possibilities and improves opportunities for companies to develop and market new green solutions.

Cleantech TIPP has launched a number of pilot projects to test companies’ green ideas. One example of this is a project testing rainwater beds that retain rainwater from roads and roofs. At the same time, the beds benefit vegetation by creating good, robust growth conditions and green urban spaces without the environmental impact of groundwater.

Experiences gained on pilot projects lead to the development of new tools that can promote sustainability while, at the same time, keeping an eye on commercialization and scaling to ensure that solutions can be competitive.




At Lolland, three times as much electricity is produced as is consumed on the island. The challenge is therefore – How do we use the green power in a sensible way when there is a lot of it? And can the energy perhaps even be filled in a warehouse?

These are some of the questions REEL seeks to answer through a demonstration project at Lolland. The project will look at the prospects of involving citizens and companies’ own buildings in the work of balancing the grid and using the green power when it is available.

If the project is successful, the solution will benefit both the consumer and our climate. At the same time, the solution can also help to balance the electricity grid, which is an increasing need as more and more of our power is produced from renewable energy sources, which, after all, produce electricity according to how much wind blows and the sun shines.

The test results will also be used to develop possible business models for flexible energy use in buildings, thus addressing the UN’s 17th world objective of utilizing technology and knowledge sharing to promote innovation and sustainable development.


The UN’s Intergovernmental Panel on Climate Change warns against the consequences that the expected temperature increases on earth can have for future generations. Carbon 20 has addressed this challenge by developing and testing sustainable initiatives in partnerships between municipalities and private companies.

In 2011, the private sector accounted for 38 per cent of total CO2 emissions in Denmark. That is why Carbon 20 put special focus on how municipalities can support energy savings in small and medium-sized companies.

The UN’s 17th world target points to the fact that sustainable development can only be realized through strong cooperation and emphasizes the importance of sharing ideas to promote innovation.

In Carbon 20, seven municipalities entered into partnership with universities and 119 local companies and launched a large number of different experimental initiatives. Actions that concerned everything from cutting down on beef in the canteen to regulating the temperature in the server room.

The objective of the partnerships has been for the participating companies to save 20 per cent on their greenhouse gas emissions. At the end of the project, the companies had on average saved 21.5 percent CO2.


Every day the average Dane travels 39 km and the vast majority of those are traveled by car. This creates congestion on the roads, increased CO2 emissions and poor health.

Formula M’s mission is to help Danes select more sustainable modes of transport by making flexible, energy-efficient options more accessible and attractive.

The UN’s Sustainable Development Goal #17 indicates that providing better access to knowledge and technology is an important way to share ideas and promote innovation. A foundational pillar of Formula M has been a high level of knowledge sharing between business networks and municipalities, providing the necessary foundation for developing a large number of green initiatives and pilot projects.

Simple steps like making sure that electric bikes are waiting for commuters at train stations can make train rides to and from work more manageable and encourage commuters to leave their cars at home. Through experimental projects like these, Formula M has saved 1,660 tons of CO2 per year.

Through strong partnerships between municipalities, regions and companies, the project has been able to gather special knowledge of commuters’ transport habits and help guide participants to greener alternatives. Municipalities have used the companies’ experiences to anchor sustainable thinking in new activities and transport policies. Municipalities’ urban planning decisions have a huge impact on how we transport ourselves.
