Further developments in the CRS, e.g. new sector codes, policy markers, channels of delivery and reporting on the SDG target, may be necessary to improve the identification of STI-related development finance, while the development of TOSSD could provide a better picture of the development finance, including mobilised private finance and the finance devoted to development enablers and global challenges. In addition, future work may consider other sector codes as support to STI, e.g. sector codes relating to renewable energy or energy efficiency. Figure 3.3 shows the different approaches used to identify activities in the areas of science, technology and innovation. The text mining analysis used to identify additional activities with STI-related components in stage three are based on development providers' current reporting of their activities to the CRS.
