The Government Financial Transfers (GFT) database measures and classifies support provided to fisheries, an important indicator of either government commitment to the sector or the potential for reform. The key principles suggested by the OECD may help the selection of relevant green growth indicators (Box 1.11). Indirect indicators can be useful when direct ones are impractical or ambiguous. For example, measuring the availability or use of energy audits demonstrates increases in environmental awareness on the part of fishers and indirectly measures energy efficiency.
