The document discusses measuring innovation for sustainability and the green economy. It describes the NETGREEN project, which analyzed existing indicators for measuring progress toward sustainable development and the green economy. It discusses challenges in measuring eco-innovation, as the effects of innovation on the environment are indirect. Eco-innovation indicators attempt to capture different stages of impact, from inputs like R&D to outputs like patents to outcomes like new technologies and environmental impacts. However, indicators are often misunderstood because their interrelations are complex. There is a need for better access to indicators and explanation of their appropriate uses and limitations.
