This document discusses the need for standardization in the energy efficiency sector to increase investment. It outlines that a lack of standardization currently results in greater performance risk, uncertainty, higher transaction costs, and difficulties building capacity and aggregating projects. The document proposes an international framework called the International Credentialed Protocol (ICP) that would establish best practices, independent verification, and transparency to reduce owner and investor risk and costs. Projects that follow ICP standards would be considered "Investor Ready Energy Efficiency" and could access an investor network with over €4 billion for funding such qualified projects.
