Green IT checklist for large enterprises

The purpose of the questions on this page is to evaluate the sustainability of the ICT infrastructure of an enterprise. If a question cannot be answered with "yes" there could be potential for improvement.

1. Strategy and Organization
1.1 Is the responsibility for sustainability and/or environmental issues and/or Green IT in your enterprise assigned?
1.2 Is in your enterprise strategy a plan for sustainability in the ICT area included (Green IT Strategy)?
1.3 Is the Green IT Strategy in the existing environment management systems of the enterprise integrated?
1.4 Are the the ICT services units and ICT infrastructure units consolidated?
1.5 Are the cost of all the ICT Services allocated and billed by user departments for the whole company?
1.6 Are efficiency objectives, planned actions and their significance as well as progress communicated clearly internally and externally (communication plan)?
1.7 Does your enterprise participate in federal and cantonal initiatives for the establishment of standards and recommendations?
1.8 Is there an education concept in addition to the communication plan for the employees?
2. Energy management
2.1 Is there an energy management system implemented which includes all the energy types (oil, gas, gasoline/diesel, electricity, etc.)?
2.2 Is the energy consumption in the ICT-area known, is it measured?
2.3 Is the energy consumption in addition to the hardware also measured in the ICT services and software area?
2.4 Is the energy data included in existing key figure systems in order to determine the current state and to be able to quantify ongoing developments?
3. PC workplace
3.1 Are PCs if not used in the sleep mode and will they be switched-off completely at the end of the workday (avoid apparent off-mode)?
3.2 Are energy savings programs on the workplace PC used (energy management tools), which allow to adapt the electricity consumption to the needed performance?
3.3 Are in the place of fully equipped workstations thin clients used?
4. Display
4.1 Is the energy savings mode in the displays activated?
4.2 Are the displays when not in use for longer periods switched off?
4.3 Is after delivery of the displays the brightness adapted, respectively optimized?
4.4 Are the screen savers deactivated?
5. Printer
5.1 Are printers in standby mode during the workday and switched off at night?
5.2 Are the default values in the printer drivers set to black and white?
5.3 Is to a large extent recycling paper used?
5.4 Is double page printing routinely used?
5.5 Are toner cartridges collected in order to refill and reuse them?
5.6 Are primarily multifunction printers used?
5.7 Is printer centralization enforced?
5.8 Are printers preferred which do not have combined toner and development units?
6. Server / Datacenter
6.1 Is server operation systematically optimized (for example through application of cloud computing)?
6.2 Are the newest available energy optimized technologies used? Are old servers being replaced early on by the most modern ones?
6.3 Was workplace virtualization with thin clients implemented?
6.4 Is application consolidation on the servers taking place?
6.5 Is server virtualization taking place (several virtual servers on one physical server)?
6.6 Are the energy savings functions on the server used?
6.7 Are servers with energy efficient processors preferred?
6.8 Are blade servers used?
6.9 Are energy efficient communication adapters/components for servers used?
6.10 Are servers equipped with energy efficient fans?
6.11 Do you pay attention to adequate size of servers?
6.12 Are servers which are only temporarily in operation switched off when not in use? Are dead servers completely switched off and separated from the network?
6.13 Is for data storage a specific storage technology used (Direct Attached Storage, Network Attached Storage oder Storage Area Network)?
6.14 Is data administration addressed effectively (Information Lifecycle Management, De-duplication)?
6.15 Is efficient storage media used (e.g. magnetic tape for backups), respectively the storage media tailored to the requirements?
6.16 Are intelligent switches for servers applied?
6.17 Is the cooling of the servers in the dedicated server room optimized and the temperature adjusted to the highest by the supplier recommended room temperature?
6.18 Is the uninterruptible power supply (UPS) optimized as much as possible for energy efficiency ?
6.19 Are flywheel systems considered to deal with short power interruptions rather then the batteries in the UPS?
6.20 Do you pay attention for an efficient load of the UPS?
6.21 Are intelligent power strips (with integrated monitoring and measuring functions) used in the racks?
6.22 Are the power generators for longer power interruptions clearly not over dimensioned.?
7. Network
7.1 Are WiFi Access Points switched off when not used for a longer period (for example with a timer)?
7.2 Are the WiFi routers powered by the Eithernet?
7.3 Is the Wake-on-LAN function of the workplace PCs deactivated?
7.4 Are in the Local Area Network for PCs and peripheral units intelligent switches used?
8. Social and ecological aspects
8.1 Are the introduced IT-products checked for environmentally friendly production and gray energy?
8.2 Are the social responsibility of the producers and the working conditions of their suppliers considered when buying a product?
8.3 Are replaced and redundant products returned to the sellers or otherwise properly disposed?
8.4 Is there a collection point in the enterprise for the disposal of old products?
8.5 If products are acquired is the energy need checked and are primarily products with energy labels bought?
9. Various
9.1 Are network adaptors when not in use separated from the socket?
9.2 Is the concept of desk sharing implemented, meaning the use of PCs which are only partly used by several employees?
