Sonderborg – The future zero carbon city


The 76,000 citizens of the little-known Danish municipality Sonderborg act, while politicians talk and climate change is accelerating. They share the vision of ProjectZero and have committed themselves to make Sonderborg zero carbon by 2029.

Sonderborg is a picturesque municipality close to the water and the German border, and it wants to prove that climate neutrality is achievable when cities take decisive action and ensure citizens and companies participate in finding new solutions and retrofitting society’s energy consumption and generation.

The ProjectZero visionary project is focused on transitioning Sonderborg into a ZERO carbon community, based on sustainable growth and creating new green jobs. Energy efficiency and energy from the area’s own renewable sources are the key means to turn the vision into reality. New thinking is essential and public policy and investments fuel the transition.

In SmartEnCity, Sonderborg seeks to

  • Demonstrate ambitious electrification of Sonderborg’s Roadmap2020, including integration of wind energy from coastal near turbines and rooftop PV power production
  • Integrate local green power production in district heating networks and green mobility solutions
  • Energy retrofitting existing house association buildings in close cooperation with tenants
  • Engage the citizens as co-designers of the Smart Zero Carbon Sonderborg ambition based integrated solutions, comprehensive learning and the introduction of new ICT based energy information.
