Copenhagen Cleantech Cluster has evaluated many prevalent definitions and categorisation methods of cleantech, but have found no single definition which encompasses the full spectrum of cleantech.

Therefore, we have developed a definition and categorisation as evident below.

Definition

Activities which develop (including consultancy and research), produces or implement new or improved processes or products, that contribute to:

• Produce renewable energy or sustainable materials
• Reduce the use of natural resources by exploiting the resources or energy more efficiently
• Reduce the harm caused by fossil fuels
• Reduce pollution problems through products, processes and / or consultation.

Under this definition, CCC uses a categorisation based on the cleantech field being perceived as anchored in technology from a conceptual point of view.
