(CSRwire) COLCHESTER, Vt.--(BUSINESS WIRE)--Nov. 30, 2005--Green Mountain Power (NYSE: GMP) today issued its first Corporate Responsibility Report, documenting the Company's progress towards sustainability. Using the Global Reporting Initiative guidelines, Green Mountain Power describes the environmental, social and financial dimensions of its operations.

"All our stakeholders, including employees, shareholders and the communities we serve, expect us to be accountable for our actions. Publishing a corporate responsibility report is an important way to communicate transparently about where we have performed well and where we need to improve," said Chris Dutton, Green Mountain Power's President and Chief Executive Officer. This is a new report that will be published each year in addition to the corporation's annual report to shareholders.

The decision to migrate from an environmental report to a Corporate Responsibility Report was an outgrowth of Green Mountain Power's renewed focus on environmental improvement. After the Company emerged from its financial crisis in the late 1990's, senior management took a harder look at how to achieve a level of environmental responsibility beyond mere compliance with laws and regulations. According to Mr. Dutton, "Those of us who do business in Vermont understand that we have a responsibility to contribute in meaningful ways to the economic health of the region, while doing our best to protect and enhance the environmental and social qualities of life."

The Global Reporting Initiative (GRI) uses a multi-stakeholder process to develop and disseminate globally applicable Sustainability Reporting Guidelines. The Guidelines were created for voluntary use by organizations for reporting on the economic, environmental and social dimensions of their activities, products and services. GRI is a collaborator of the United Nations Environment Program and works in cooperation with the UN Global Compact.

Green Mountain Power's Corporate Responsibility Report, consisting of 44 pages, is divided into three sections: financial reporting, environmental reporting and social reporting. The document is designed to be accessible and easy to read, while noting which Global Reporting Initiative Indicators are addressed.

Green Mountain Power asked Woodard & Curran, an environmental engineering firm, to provide third-party verification of the accuracy of the information in the report. Woodard & Curran was given access to all legal, social, environmental and financial data in order to conduct its review.

"Green Mountain Power's values are closely intertwined with the values of Vermont. We have reduced our dependence on fossil fuels and pursued renewable resources. We built our Searsburg wind facility, which at the time was the largest commercial wind plant east of the Mississippi River. We are an organization that works hard to eliminate waste - not only of resources, but of time and energy. This report shows our effort to become more efficient achieves not only economic benefits, but environmental and social ones, as well. We hope other Vermont businesses will come to see the value in this type of disclosure and consider publishing their own reports," said Mr.
Dutton.
