The Vanguard Group is one of the world's largest investment fund managers, with $750 billion in assets under management. Vanguard has 10,000 employees and 18 million institutional and individual investors.
Vanguard rated the energy performance of its over one million square feet of office and financial centers, and has achieved significant improvement in energy efficiency without large capital expenditure, through high-level commitment, aggressive efficiency goals for each facility, and an overall greater focus on energy management. In addition, Vanguard is helping advance energy efficiency on a national scale through the Vanguard Calvert Social index Fund. This fund tracks the performance of the Calvert Social Index, a benchmark for socially responsible investors, which in 2003 outperformed more than four-fifths of its peers in the overall US mutual fund universe with similar investment styles.
Vanguard joined ENERGY STAR in 2001.
