For the fourth year in a row, Computerworld set out to identify organizations that are implementing smart, efficient strategies to achieve "green IT."
Organizations were invited to complete a comprehensive questionnaire online from June to August. The survey was sent out to the IT community through a variety of channels, including email newsletters, Computerworld.com and email broadcasts. Seventy organizations participated.
Computerworld then contacted representatives at the participating organizations to verify that the information provided on the surveys was truthful and accurate. Only those organizations that filed verification letters were considered.
Computerworld then applied a set of criteria, developed with the help of green-IT industry experts, to identify the organizations that are working to reduce energy consumption by IT equipment and using technology to conserve energy and lower their carbon emissions. A separate list was created to showcase IT vendors and data center suppliers. Included in this category are hardware, software, networking, IT infrastructure and data center vendors.
Based on the weighting scheme developed, the top 12 Green-IT Users and top 12 Green-IT Vendors lists were chosen.
What follows is the survey and scoring system that Computerworld used to select the "greenest" companies from among the nominees.

Part II: Essays
Note: Responses were limited to 500 words.
1. Please describe your organization's efforts in the past 18 months to reduce the consumption of energy (especially energy derived from fossil fuels) by information systems, as well as technology-related recycling programs and technology support for telecommuting. Please include information about the anticipated payback from these green initiatives, as well as a timeline for when the initiatives were begun and when they are expected to be fully in place. Also, you may use this space to clarify or elaborate on any of the answers you gave above.
2. Please describe your organization's future "green" efforts -- those that are either in the works or are planned for the next 12 to 18 months.
