The Renaissance Green IPO Index captures the performance of newly public companies whose products and services offer solutions to environmental problems. Green enterprises, such as solar companies and biofuel producers, frequently manifest themselves first through the IPO market, enabling the Renaissance Green IPO Index, a subset of the Renaissance IPO Index®, to capture the earliest performance of these new green business ideas. Green sectors of the Index include alternative energy, recycling, conservation, clean transport, energy efficiency, and green-enabling technologies.
