In recent years, factors such as sustainability, digitalization, climate change, energy transformation, social inclusion, gender parity, and Environmental, Social and Governance (ESG) risk have been playing an increasingly important role in the process of financial transformation. The effect of the impact is increased regulation and guidance for financial markets, in relation to adapting current activities to meet the new challenges, for example:•The process of greening finance and spreading the blue wave in finance.•Building sustainable value in the business models of financial institutions.•Creating an offer of sustainable financial products.•Ensuring parity between women and men in the decision-making bodies of financial institutions.•Sustainable ratings.•Climate stress tests.This book focuses on the intersection between nature and finance and offers a comprehensive overview of the trends, transformations and challenges in finance and the financial markets related to the effects of sustainability concepts or ESG factors. The book has been designed to show these trends, through the evolving subdisciplines of finance, such as green and blue finance. It presents critical recommendations for the ecosystem and network of finance in the era of ESG and sustainability and paints a comprehensive picture of contemporary finance, identifying the factors determining its sustainable transformation. This is one of the first books to present the issues of sustainability and ESG risk in finance through the prism of individual types of finance. Not only will the book appeal to scholars and researchers in the field of banking, economics, finance and accounting, but it will also find an audience among policymakers and practitioners involved in the finance and sustainability discourse.
