DENVER, April 30 /PRNewswire-FirstCall/ -- ProLogis (NYSE: PLD), the world's largest owner, manager and developer of distribution facilities, today released its first annual Sustainability Report.

The report provides detailed information about ProLogis' economic, social and environmental performance during 2006. Written according to guidelines issued by the Global Reporting Initiative (GRI), the report will be updated annually and made available as a companion document to the company's annual report to shareholders.

"We're extremely pleased to present this report and believe the information it contains will be useful for investors, employees, regulators, community organizations and the customers we serve around the world," said Jeff Schwartz, ProLogis chief executive officer. "We are striving to build a truly sustainable global enterprise, one that delivers enduring value to all stakeholders. Measuring and reporting our environmental and social performance, along with our financials, will be one of the most important ongoing steps we can take to achieve that end."

ProLogis is the first U.S. real estate company to issue a Sustainability Report under standards promulgated by GRI, a non-profit organization based in Amsterdam and sponsored by the United Nations Environmental Programme. The GRI framework is the most widely adopted by companies globally in the area of sustainability reporting.

"As such, we believe the performance targets we have established for ourselves will deliver real, long-lasting benefits to the environment, and set an important benchmark for other companies in our industry. Though aggressive, we believe these targets are achievable in the designated time frame, and we look forward to updating stakeholders on our progress over time."

ProLogis' sustainable development program includes pilot projects at locations in Asia, Europe and North America; development initiatives and building design standards; customer offerings; and formal training and certification of construction-management professionals. The company recently became the first in the real estate industry to join the Chicago Climate Exchange, an organization that enables companies to reduce net greenhouse gas emissions through market-based trading of carbon credits. In 2006, ProLogis was recognized for the strength of its environmental program with a "Leader in the Light" award from the National Association of Real Estate Investment Trusts (NAREIT).
