Environmental asset classes are not a hope for tomorrow but a reality today. This new asset category promises to grow dramatically in the 21st Century as financial analysts, investors, and corporations around the world try to find ways to profit or reduce costs while promoting environmental social benefits. Sustainable Investing and Environmental Markets: Opportunities in a New Asset Class presents a groundbreaking new way to "do well and to do good". With a combination of over 50 years of practical experience in the field of environmental finance, Richard Sandor, Nathan Clark, Murali Kanakasabai and Rafael Marques provide a solid preliminary understanding of the promising and transformational new investment category of environmental assets. Three broad asset classes -- air and water; catastrophic and weather risk; and sustainability -- are covered across 12 chapters which analyze how these environmental asset classes are currently being incorporated into commodities, fixed income, and equity instruments and what the future holds for the field.
