This Ph.D. dissertation is the result of research on the Topic of Sustainable Finance applied to Socially Responsible Investment funds at the University of Jaume I. I am grateful for the support of many people and institutions along the process.First of all, the author wishes to express sincere appreciation to both supervisors for their assistance in the preparation of this manuscript. Their support and guidance throughout the process have been critical for success. Professor María Jesús Muñoz Torres was an inspiration since the start of the process as she was my supervisor in the Masters of CSR and Sustainable Finance (UNED-UJI) and guided me on the path of the Ph.D. Professor Idoya Ferrero's help and insights throughout the process were extremely valuable. I want to thank both supervisors for their constant availability, enthusiasm, and kind words of support during these years.In particular, I wish to express my gratitude to Universitat Jaume I for offering me the opportunity to do my research and access transversal courses and formation. My sincere gratitude is extended to experts of this Ph.D. dissertation, whose comments will help them improve the quality of this work.Finally, I want to thank my family and friends. My children (Claudia and Nacho) have been an inspiration and a driver to overcome difficulties through their smiles and hugs. My mother and sister for listening to me and helping me overcome the setbacks of the process. My father who gave me throughout my childhood all his love and helped me believe in myself. And last to my husband for giving me the love and support that I needed to embark on this journey.
