Katherine Gajewski is the Director of Sustainability in the City of Philadelphia where she is responsible for the implementation of Greenworks Philadelphia, the city’s sustainability framework unveiled by Mayor Nutter in April 2009. The framework sets goals in five areas — energy, environment, equity, economy and engagement — and encompasses more than 150 achievable, measurable initiatives. Implementation of these initiatives will reduce the city’s vulnerability to rising energy prices, limit its environmental footprint, and reposition its workforce and job development strategies to build upon Philadelphia’s competitive advantages in the emerging green economy. Clarena Tolson is the Commissioner in the City of Philadelphia for the Department of Streets, which is the agency in charge of implementation for the City's LED program. Steve Buckley is the Deputy Commissioner in the City of Philadelphia for the Department of Streets, and was the project manager for the City's LED program.
