Eco-investing or green investing is a form of socially responsible investing where investments are made in companies that support or provide environmentally friendly products and practices. These companies encourage (and often profit from) new technologies that support the transition from carbon dependence to more sustainable alternatives.Green finance is "any structured financial activity that has been created to ensure a better environmental outcome."

In the present book, twelve typical literatures about Eco-investing published on international authoritative journals were selected to introduce the worldwide newest progress, which contains reviews or original researches on Eco-investing. We hope this book can demonstrate advances in Eco-investing as well as give references to the researchers, students and other related people.
