What is Cleantech?

Our definition of “cleantech”

CLEAN has evaluated several prevalent definitions and categorisations of cleantech, but we have found no single definition which encompasses the full spectrum of cleantech.

Therefore, we have developed the definition and categorisation.

We define cleantech as activities which develop (including consultancy and research), produce or implement new or improved processes or products, that contribute to:

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