Carbon management and accounting is a new challenge for many technology officers, as more organizations look to measure, report, and reduce energy use and associated greenhouse gas (GHG) emissions. HP Enterprise Services provides an end-to-end solution with HP Carbon Emissions Management Service (CEMS), which can help businesses calculate, record, and analyze carbon emissions across information technology (IT) operations.

HP CEMS is a comprehensive service that includes four key elements:

• • Baseline—Establish a baseline of GHG emissions and energy use.
• • Road map—Develop a road map to decrease energy use and carbon dioxide (CO2) emissions by up to 40%, and reduce total cost of ownership by up to 30%.
• • Execute—Conduct ongoing reporting of carbon emissions and energy use from IT operations, while tracking progress toward reduction targets.
• • Governance—An optional governance model focuses on more sustainable IT, mitigating climate risk, and meeting corporate sustainability goals and objectives.

Beyond driving an organization's sustainable business agenda, HP CEMS can produce quantifiable cost savings. It analyzes all devices, from laptops to data centers, to identify the best opportunities for energy savings, while addressing questions such as:

• • Which business units have the highest GHG intensity?
• • Are IT systems appropriate for current and future business needs?
• • Should the organization consolidate, restructure, or retire certain systems?

For example, an international packaging company turned to HP CEMS to see exactly which areas of its organization could reduce energy use. HP CEMS enabled server virtualization, replaced CRT monitors with LCDs, and replaced PCs with thin clients, aiming to reduce CO2 emissions by up to 33% over 4 years.

HP CEMS also worked with a leading Australian bank to establish a baseline of its carbon impact and set a goal to reduce CO2 emissions by up to 39% over 3 years. Also in Australia, HP CEMS measured individual and overall energy consumption for equipment at a major paper manufacturer, including printers, desktops, laptops, and servers. This gave the company a clear set of outcomes and new goals for a 3-year IT plan to cut 30% of total power usage.

These efforts are expected to result in direct energy savings and lead to a smaller carbon footprint over time. In addition, HP CEMS can reduce maintenance costs, improve asset utilization, and increase productivity. This holistic approach delivers an efficient return on investment leading to improved shareholder value.
