This IEA report, commissioned by G7 energy ministers, presents the first global overview of market-based instruments (MBIs) for energy efficiency, such as auctions, energy efficiency obligations on utilities and white certificate programmes. Special attention is given to the fact that these MBIs need to be compatible with the wider policy framework for energy efficiency that could include grants and tax exemptions for energy efficiency measures. IEA’s research found that the number of MBIs has quadrupled over the last ten years, while investment stimulated by these instruments has risen six-fold, to USD 26 billion in 2015. The report is available to download on the IEA website.
