Green Index is a strategic management decision tool for measuring the "holistic" green performance of companies. It clearly points out investment prioritizations for a company, for improving its green performance per Dollar revenue generated. The model is the first index that is collectively developed by VCs/Investors, entrepreneurs, academics, executives and sustainability NGOs' leaders. With the Green Index, unlike any other sustainability index in practice, Green Performance is measured in terms of the revenue generated by a company. Green Index has three main building blocks as: Environmental Performance, Green Innovativeness, Financial Performance, that are integrated for defining green performance.
