About

Green Performance Strategies is a joint offering of iSpring and FourScore LLC.  We believed that there was a way to combine our passion for sustainability, our belief in the value of metrics, our expertise in business process and finance  and our fascination with the mechanisms of clear, concise communication into a service that would help all kinds of organizations find new ways to apply sustainability principles to achieve a better bottom line and a better world.  GPS is the result of that collaboration.

Plus we thought it would be fun to work together.
