Report Guide

[3.1-3.3] This is ProLogis' third sustainability report, which is global in scope and covers our activities in North America, Europe and Asia during Fiscal Year 2008, except when otherwise noted. ProLogis publishes its report on an annual basis; the last report was published in April 2008 and covered Fiscal Year 2007. Enhancing our commitment to reducing energy consumption and use of natural resources, this year's report will be published in electronic format. This concept also enables us to include additional charts, graphs and supplemental information. Additionally, the GRI Content Index and GRI Profile Indicators will appear not only in a list as referenced above, but also hyperlinked within the body of the text to signify the specific disclosure it meets. We believe this change will improve the reader's overall experience.

Since our last report, there have been no re-statements of information provided in the sustainability-related disclosure. However, due to the global financial crisis and economic downturn, ProLogis has made changes to the structure and operations of the company (detailed in the Company Overview section) and is not currently focused on starting new construction.

[3.5-3.11] The basis for reporting on other matters specific to the operations of our business, including joint ventures, subsidiaries, leased facilities, outsourced operations and other entities that can affect comparability from period to period, can be found in ProLogis' Annual Report on Form 10-K, which is filed with the Securities and Exchange Commission and also is available in the SEC Filings section of ProLogis' website at:
http://ir.prologis.com/sec.cfm.

This report is intended to provide information about the most significant sustainability-related impacts that arise from our business activities and is focused on those over which we have the greatest degree of control or influence. By identifying and reporting on the most material issues to ProLogis and its stakeholders, we ensure that our reporting remains relevant and useful.

To the extent possible, we have included data from internal resources or with the help of our business partners. When original data was not available, we relied on third-party sources for estimates.

This report incorporates the most recent G3 Guidelines as released by the Global Reporting Initiative (GRI) as a general framework for this report. GRI is an international, multi-stakeholder network through which a recognized sustainability reporting framework has been developed. This report has been externally assured and GRI-checked as meeting the requirements for GRI's Application Level "B+".
