On the other hand, it can also address the offer side of the problem by increasing capital availability and adequacy for private sector projects dealing with green growth and climate action (e.g. small-scale adaptation-related projects, innovative green growth projects), through direct financing (e.g. grants, challenge funds), risk sharing mechanisms which improve the risk-return profile of investments (e.g. guarantees), provision of medium to long-term finance to cover the longer payback of relatively new green technologies, etc. The global average is computed by taking a simple average of country-level point estimates. For each economy, only the latest available year of survey data is used in this computation.
