World’s first City Data Marketplace in Copenhagen as Smart City Driver  


In partnership with Hitachi, Copenhagen has launched the world’s first marketplace for city data. The City Data Exchange is providing both public and private data from the metropole. With a special focus on challenges in the city, the data enable new knowledge about e.g. traffic patterns and citizens’ energy consumption, which companies can use to develop new, innovative solutions to create smarter cities.

Copenhagen’s new City Data Exchange follows in the footsteps of similar projects such as the pioneering Leeds Data Mill, but the Copenhagen portal is the first platform to monetise data and create a city data market.

Copenhagen has been a trailblazer in smart city initiatives since declaring its ambition of becoming carbon-neutral by 2025, and the data marketplace brings Copenhagen at the forefront of collecting and using data to develop new smart city solutions to handle the challenges of urbanisation and climate change. 

Data are key to smarter solutions

The City Data Exchange team has already found 65 sources of open data on Copenhagen –everything from demographics to weather and crime statistics. By combining this with information submitted by citizens and businesses, the platform enables advanced analytics to improve areas such as green infrastructure planning, traffic management and energy usage.

“The City Data Exchange is a market place where you can buy and sell data (some will also be free of charge) and it has a special focus on data related to the challenges in the city,” said Peter Bjørn Larsen, CDE Copenhagen Director, Hitachi. “It should not be seen as a replacement for open data portals, but an addition.”

Strong public-private partnership with Hitachi as project lead

The platform is built in partnership with the City of Copenhagen, the Danish Capital Region, the Danish cleantech organisation CLEAN and a consortium of partners. The City of Copenhagen and the Danish Capital Region are financing the project. Hitachi Consulting won a tender to lead the project and in May 2015 started working on both the technical solution and building up the ecosystem of data suppliers and consumers.
