The finance sector has a crucial role to play in delivering a sustainable future for the planet. To address the Triple Planetary Crisis of climate change, pollution and biodiversity loss, it is vital that the finance sector rapidly accelerates the mobilization of capital to support a successful and just transition to net zero. This requires enhancing both the capabilities of financial institutions and developing the knowledge and skills of finance professionals so that every financial decision takes account of climate change and sustainability. Green and Sustainable Finance is a comprehensive guide to the principles and practice required to manage sustainability risks, engage and support clients, and take advantage of the opportunities presented by the transition of sectors and firms to new, low carbon and nature positive models. This fully updated third edition incorporates a wider perspective with nature-based impacts, risks, dependencies and opportunities considered alongside climate change. It introduces the work of the new International Sustainability Standards Board (ISSB) and the Taskforce on Nature-related Financial Disclosures (TNFD) along with extensive coverage of wider regulatory and market developments. There is also additional content on adaptation finance, transition finance and transition planning. Endorsed by the Chartered Banker Institute as the core text for the global benchmark Certificate in Green and Sustainable Finance, this book is essential reading for finance professionals, university students and individuals working to embed sustainability in business, finance, policy and regulation.
