This category welcomes – amongst others – submissions that show established and innovative pathways for renewable energy production. Such solutions do include technologies, but also new forms of organisation and ownership to integrate renewable energy generation in our cities. We are also looking for clever strategies for how citizens can drive the transition towards renewable energy from the bottom-up.

This category welcomes – amongst others – submissions that show how we can grow our food and design our diets in a way that is more climate-friendly and helps to reduce our carbon footprints. We seek strategies for producing and distributing food in a more localized way, healthy diets that use significantly less meat, projects for how to reduce food waste or initiatives that use food and agriculture for a healthy relationship between the city and its surroundings.

This category welcomes – amongst others –  proposal aimed at moving from a linear to a circular economy such as efficient prevention and management of waste, the re-use of materials for production processes, solutions that contribute to minimizing the generation and maximize the recovery of municipal waste as well as special waste and hazardous waste management. Share your innovative and truly sustainable business idea, product, campaign or investment strategy to make a circular economy without waste and emissions a reality!

This category welcomes – amongst others – submissions that show how transport and mobility can be organized with less or without the use of fossil fuels.

This category welcomes – amongst others – submissions that present new ideas and visions for the organisation, design and management of public spaces for a low carbon urban future.

This category welcomes – amongst others – urban strategies, designs and best practise projects for the built environment in a low carbon city. We seek urban planning solutions for multi-use urban layouts that reduce the need for travel and enable low-carbon lifestyles, participatory projects and citizen-driven projects that deal with low carbon urban development. Share your projects for energy-efficient or energy positive buildings. In the context of the upcoming Habitat III conference in Quito, Ecuador we are also very interested in new policy approaches that enable and support the building of a low carbon city.

This category welcomes – amongst others – examples for education and awareness raising projects across age, gender or cultural background.
