Global Cleantech Innovation Index Framework

GCII Home

Drawing from 15 indicators, the second edition of the Global Innovation Index evaluated 40 countries based on an average between inputs to innovation and outputs of innovation.

  • inputs correspond to the creation of innovation (the development of technology supply)
  • outputs relate to the country’s ability to commercialise innovation (the creation of market demand)

Each of these inputs and outputs are determined by four equally weighted pillars as shown below. The four pillars are built from a total of 15 indicators, drawn from both third party research and CTG’s proprietary data. More information on the underlying sources can be found in Appendix A of the 2014 Report.

Global Cleantech Innovation Index Framework


The GCII is a biennial evaluation of performance, rather than as a time series study. Year-on-year comparisons (i.e. 2012 compared to 2014) cannot necessarily be validly interpreted. While all 15 indicators used in the 2012 framework were also used in the 2014 framework, 3 indicators were modified and other small methodological changes were made (See Appendix A in the report). The framework is revised every two years based on feedback from prior editions and to take into account new data sets in order to continually improve the way that cleantech innovation is measured.
