This book contains various lectures delivered by high-ranking representatives from academia as well as from companies and institutions in the banking and finance sector as part of the lecture series "Social Finance" and "Social Banking" at the Alanus University of Arts and Social Sciences in Alfter. This documentation makes a timely contribution to the increasingly important question of what factors hinder greater sustainability in the financial sector and what innovative approaches have been developed to create a more sustainable financial sector. The contributions illuminate the broad field of social and ecological action in the banking and finance sector, presenting practical perspectives from social-ecological banks, as well as topics ranging from socially responsible investment to an economy of giving and the associated instruments.
