In an effort to offset energy usage with an investment of several million dollars, Esri recently commissioned the installation of 2,737 rooftop solar panels on three office buildings at its main campus in Redlands, California. Esri's solar energy system will reduce global carbon emissions by more than one million pounds annually, the equivalent of planting 70,000 mature trees. The 195-watt solar panels will produce 533 kW of electricity—enough to power 100 average homes.

"At Esri, we have always supported wise and careful allocation of the world's natural resources, and with GIS technology, we've been able to play a role in making sustainable development possible," says Jack Dangermond, Esri president. "We turn that scope inward as well to make environmentally responsible business decisions."
