Diageo, Norwalk, Conn.’s largest employer, began using power from 100 percent renewable sources at its North American headquarters on Main Avenue. “By purchasing electricity derived from renewable sources, like wind or solar power, we will reduce our carbon emissions in Norwalk by more than 92 percent,” said Diageo North America President Larry Schwartz. Schwartz, Norwalk Mayor Richard Moccia and employees celebrated the milestone with a ribbon-cutting and “green” champagne toast. Diageo’s facility in Norwalk has earned an Energy Star from the USA Environmental Protection Agency and the building is currently being assessed for LEED certification.
