A ground-breaking work that addresses a crucial challenge facing our planet and the finance discipline, this book discusses key omissions in finance theory, principles, and equations, and explores recent developments in sustainable finance/ESG integration. It reveals a spaceless analytical framework and a sustainability debate that avoids the very logic of money creation. A theoretical treatise on sustainability in finance, the book makes the case for the hardwiring of sustainability into financial mathematics, offering a complementary principle and new equations for the purpose, while also discussing the implications of such a transformation for money mechanics.
