Innovation Awards
The Rethink Cities Startup Awards spotlight pioneering startups driving cities towards sustainability and climate neutrality through innovative solutions.
Rethink Cities Summit
Rethink Cities Summit is a global summit focusing on implementing solutions to make cities more sustainable. We believe many of the solutions we need for that, already exist, so the summit’s purpose is connecting them to challenges, scaling the knowledge and best practices for optimal implementations.
Sønderborg: The Global Capital of Energy Efficiency
Sønderborg stands at the forefront of energy efficiency and urban sustainability, driven by the ambitious goals of Project Zero.
Recognized globally for its commitment to achieving climate neutrality by 2029, Sønderborg serves as the ideal host for the Rethink Cities Innovation Award, exemplifying what’s possible when cities commit to innovative and sustainable development.
Project Zero and
Supporting Organizations
Project Zero is a public-private partnership founded in 2007 by the city of Sønderborg and the Bitten and Mads Clausen Foundation, which has been instrumental in putting Sønderborg on track to achieve carbon neutrality by 2029. This initiative has earned Sønderborg recognition as the Global Capital of Energy Efficiency by the International Energy Agency (IEA), positioning the city as a leader in sustainable urban development.
