Book excerpt: Michael Migendt explains the role of alternative investments in supporting the growth of a sustainable economy and recognizes levers that policy makers, managers and entrepreneurs could use for further accelerating green innovation through finance. He focuses on specific examples of alternative investments into green industries, companies, projects, and infrastructure, covering the developments along the innovation chain. Especially the acceleration of green technologies and the in this context occurring interrelations between the three areas of finance, innovation, and policy are key to this work.
