Copenhagen Smart City

Denmark has a highly developed economy and perfect social welfare. Danes have always taken a holistic view of urban development, taking into account the environment, residents and businesses. Copenhagen also won the title of the smartest city in Europe. Copenhagen currently has the lowest carbon footprint per capita in the world and has the most aggressive carbon reduction plan of any major city in the world. The city government not only vigorously promotes low-carbon energy-saving policies, but also plans to achieve carbon neutrality by 2025. To explore the context of its policy promotion and urban development, the development of smart cities and innovative solutions is one of the important boosters to achieve this goal. Copenhagen's smart city plan aims at sustainable development of the environment and improving the quality of life of citizens. Through the construction of sensing equipment, information sharing platforms, and experimental fields, it proposes systematic and innovative methods to solve urban problems, including monitoring air quality, Relieve traffic congestion, improve the efficiency of garbage removal, widely distribute wireless networks, etc.

As Europe's smartest city, Copenhagen has ambitions to become the first carbon-neutral city by 2025. Achieving this goal relies heavily on the municipality's Climate Action Plan - launching 50 initiatives to meet its 2015 interim target for carbon reduction 20%. Copenhagen has also set core goals, including improving energy efficiency, using renewable energy, green building standards (all new buildings should be carbon-neutral by 2020) and increasing transport options. The challenge for many cities is maintaining a balance between environmental protection and economics as they strive for urban sustainability. With sustainable urban solutions, Copenhagen is getting closer. Research in Copenhagen shows that green industry revenues in the Capital Region increased by 55% over 5 years.

The reason why Copenhagen was rated as the smartest city in Europe has a lot to do with its sustainable urban solutions. Copenhagen improves traffic mobility with the integration of traffic and ride solutions, significantly reduces congestion, and improves the health of urban residents; and Copenhagen has a clean harbor, making urban areas more attractive: higher quality of life, increased longevity of local businesses, Increased job opportunities and income; the treatment rate of waste plants only accounts for 1.8% of all waste treatment; through district heating, the urban heating demand of 98% is met.

In order to effectively promote the smooth progress of Copenhagen's smart city plan, a coordination committee was established to assist the public sector, private companies, and research institutions to jointly implement it. Different from the promotion framework of the previous official-led plan, companies and research institutions participating in the smart city plan can participate Responsible for promotion, it is a partnership with the public sector, and each other responds to rapidly changing new technologies with a more flexible operating model. In the process of proposing solutions, the public sector or private companies will invite relevant citizens and business groups to participate in the discussion, solicit opinions from all parties with an open attitude, and the solutions can also be tested in the city to verify the future Feasibility of implementation across the city.

In Copenhagen, people here believe that the development of smart cities should not only promote the renewal of urban infrastructure, but also promote the upgrading and development of social thinking and industries, and it is also an entrepreneurial opportunity for new companies. According to statistics from Copenhagen Investment Promotion Agency, there are currently more than 250 companies participating in smart city-related plans, of which up to two-thirds are small and medium-sized enterprises. The development of smart cities not only improves the vitality of new businesses internally, but also provides Incentives for investment and cooperation. The most important key to Copenhagen's ability to attract technology start-ups to invest in the field of smart cities is that the public sector provides the city's streets or public places as test sites, and the mentality of citizens and public sectors that they are not afraid of failure and have the courage to try is a big help .

In the era of big data, in the process of promoting smart cities, how to make good use of big data will be one of the keys to improving development efficiency. With the promotion process, Copenhagen provides three information convergence platforms with different functional orientations: Open data, IoT Platform for Cities, City Data Exchange. Open data is a platform for opening basic urban data, such as traffic flow, infrastructure, road construction locations, and even data on cultural activities can also be queried on this platform. In 2014, Copenhagen won the Barcelona World Smart City Award for its Copenhagen Connecting Project to promote the development of urban big data. With the help of mobile phone GPS systems and sensors widely distributed in trash cans and sewers, it collects public environmental data and assists the city government to achieve the goal of a smart city , to provide citizens and enterprises with a better living and investment environment. The IoT Platform for Cities is a city IoT platform launched by the City of Copenhagen in 2017. With the support of the European Union's Horizon 2020 plan, it cooperates with Antwerp, Belgium and Helsinki, Finland to establish a platform prototype through actual verification, and integrate complex data from different sources. Standardization provides mutual use between cities, and it is expected to serve as the basis for the EU to build a platform in the future.

In order to make better use of big data development, the city government has also cooperated with Hitachi to develop a data exchange platform (City Data Exchange, CDE), which provides large, medium and small enterprises, start-up companies, public departments, and even universities and colleges with general People can publish, exchange and purchase various types of data, including population data, energy consumption data, air quality, traffic conditions, crime statistics, bicycle usage, and many other types. Through the CDE platform, the data of the public and private sectors can be exchanged with each other, increasing the frequency and value of information use. Not only can the public sector and large companies acquire more useful data to create bonus effects, small and medium-sized enterprises or start-up companies can also use data to explore, Propose innovative urban solutions, and the general public can directly participate in the process of promoting big data and smart cities, and move towards better urban development through co-creation, sharing and cooperation.
