The Corporate Library, the leading independent source for corporate governance research and risk analysis, today announced it has entered into a partnership with Trucost, the world's leading environmental data provider, to provide institutional investors with in-depth analysis of corporate environmental performance and corporate governance risk.

"The Corporate Library has always been concerned with companies' environmental impacts as they relate to corporate governance risk," said The Corporate Library's Chief Executive Officer Richard A. Bennett. "Our partnership with Trucost allows us to help our investor and other clients to understand corporate risk better by providing them with insightful and comprehensive environmental performance research."

The Corporate Library will offer clients two of Trucost's products: the environmental impact ratio which provides a measure of a company's environmental efficiency; and the company briefing which provides a detailed overview of a company's environmental impacts, measured in quantity as well as financial terms, in order to relate environmental performance to financial performance.

The addition of Trucost's products covering 4,500 of the largest companies worldwide will contribute to The Corporate Library's commitment to global coverage.

"The partnership enables us to offer The Corporate Library's clients a comprehensive understanding of the environmental performance of companies across the investment universe." said Simon Thomas, Chief Executive Officer of Trucost. "This expansion of our North American coverage reinforces Trucost's reputation as a global leader in environmental data provision."
