| Global Climate Protection Goals | Efficient Energy Sources | Energy Efficiency of AMD Products |
AMD's top executives approved a formal commitment to global climate protection on February 20, 2001. The executives renewed that commitment with the following version approved on August 28, 2006:
|
Global climate change presents a range of complex risks to the global community and our common vision of a prosperous future. AMD recognizes our responsibility as a global citizen to reduce our direct impacts on the environmental and to inspire and enable others to do the same. We do this through the development of energy efficient technology and the responsible design and operation of our facilities. Our commitment, strategy, and progress are reviewed annually at the executive level of the corporation. |

AMD's seventh annual Global Climate Protection Plan clarifies and documents the company's strategy and goals to address its impacts on the climate.
Greenhouse Gas Goals for the Future
To support our commitment, AMD has established the following greenhouse gas (GHG) reduction goals:
GHG Emissions Reduction Goal
Reduce GHG emissions (carbon equivalent emissions/manufacturing index) by 40 percent by 2007 (relative to a baseline year of 2002).
Figure 1: AMD's Normalized Greenhouse Gas Emissions from 2001 through 2006 Compared to the 2007 Goal Value |
In 2004, AMD set a goal to reduce greenhouse gas emissions (as measured by kilogram carbon equivalent emissions/manufacturing index) 40 percent by 2007 against a baseline year of 2002. Compared to an adjusted 2002 baseline, AMD has decreased normalized greenhouse gas emissions by more than 50% percent, and we have already achieved our 2007 goal. Therefore, we have established a new goal to reduce normalized greenhouse gas emissions:
Normalized greenhouse gas emissions (as measured by kilogram carbon equivalent emissions/manufacturing index) will be reduced 33 percent by year end 2010 relative to the 2006 baseline.
From 2001 to 2005 AMD was producing both microprocessors and flash memory devices. In 2006 AMD operated two fabs producing only microprocessors - Fab 30 and our new 300mm Fab 36, which is not yet fully loaded. The Dresden fabs are supported by highly efficient trigeneration facilities and have very low emissions of PFCs. In combination with renewable power purchases in Austin and energy efficiency improvements at many locations around the world, AMD’s normalized emission rate in 2006 is approximately 25 percent lower than the 2005 emission rate (see Figure 1). The 2006 baseline emission rate for our new goal is approximately 66 percent lower than the 2001 emission rate.
AMD’s normalized greenhouse gas emissions goal is supported by two other goals discussed in the following sections: an absolute PFC emissions reduction goal and a goal to reduce normalized energy use in manufacturing.
PFC Emissions Reduction Goal
Reduce absolute perfluorocompound (PFC) emissions (metric tons of carbon equivalent emissions) by 50 percent by 2010 (relative to a baseline year of 1995).
Figure 2: AMD PFC emissions compared to the 2010 PFC emissions reduction goal – 1995 through 2006 |
AMD set a goal to reduce absolute PFC emissions measured in MTCE by 50 percent by the year 2010 using 1995 as the baseline year. AMD’s goal supports the World Semiconductor Council (WSC) goal of a 10 percent industry-wide reduction of annual PFC emissions by the year 2010 compared to the baseline year of 1995. AMD has surpassed this PFC reduction goal well before 2010.
Emissions reductions were achieved mainly by introducing alternative chemistries and processes, optimizing processes, and abating process effluents. When designing and building new production facilities, AMD applied best practices and lessons learned from then existing facilities and implemented only low PFC emitting process technology.
Since PFC emissions are associated with wafer fabrication, the 2005 divesture of fab facilities in Aizu-Wakamatsu, Japan and Austin, Texas, and silicon R&D operations in Sunnyvale, CA had a major impact on reported emission totals. AMD’s remaining wafer fabrication location is in Dresden, Germany, whose fabs are equipped with low PFC emitting technology, allowing for a reduction of PFC emissions to negligible levels.
PFC emissions are expected to stay at de minimis levels for the foreseeable future. AMD will continue to monitor and quantify PFC emissions. Due to the remaining de minimis PFC emissions, AMD is not planning to establish a new reduction goal specific to PFCs. However, future fab designs and process technologies will continue to minimize PFC emissions.
Energy Use Reduction Goal
Reduce energy use (kilowatt-hours/manufacturing index) by 30 percent by 2007 (relative to a baseline year of 2002).
Figure 3: Normalized Energy Consumption 1999 through 2006 at AMD Expressed in Kilowatt-hours per Manufacturing Index (MI) |
AMD’s absolute energy use decreased from 2005 to 2006, due primarily to the divesture of Spansion facilities but partially offset by the startup of AMD Fab 36. Normalized energy use, on the other hand, increased relative to 2005. As shown in Figure 3, AMD has already surpassed the company’s 2007 goal, decreasing normalized energy consumption by 39 percent compared to the 2002 baseline or nine percent more than the goal. However, the startup of AMD’s Fab 36 in Dresden temporarily increased the normalized energy use, because a baseline energy consumption is required while the production output increases toward design capacity. As expected, despite this temporary increase, normalized energy consumption stayed well below the 2007 goal.
Aggregate growth of manufacturing capacity in AMD-controlled facilities will continue in 2007, primarily due to the continued ramp of Fab 36 and conversion of Fab 30 to 300 mm wafer manufacturing capability. As this growth occurs, AMD remains committed to designing energy efficient features into new facilities and promoting conservation measures at existing facilities. AMD has achieved our goal to reduce normalized energy use (as measured by kilowatt-hours / manufacturing index) 30 percent by 2007 against a base year of 2002. Therefore, we have established the following goal to reduce normalized energy use.
Normalized energy use (as measured by kilowatt-hours/manufacturing index) will be reduced 40 percent by year end 2010 relative to the 2006 baseline.

Achieving Goals Through Conscious Commitment
To meet these goals, AMD is buying energy from more efficient sources and has implemented a number of projects to increase the energy efficiency of our manufacturing and building operations. Highlights include partnering with a cogeneration facility and being one of the largest industrial purchaser of green energy in Austin, Texas.
Figure 4: Avoided Global Warming Gas Emissions through the Dresden Trigeneration Facilities Energy Center I and II (EVC I and II) Compared to a Conventional Energy Supply Solution |
Energy Center I (EVC I) and Energy Center II (EVC II) are specially designed trigeneration facilities that supply the electrical, heating, and cooling demands of AMD Fab 30 and AMD Fab 36, respectively. EVC I began supplying energy to Fab 30 in 1998. During its initial nine years of operation, the trigeneration system has achieved a total average energy efficiency of more than 72 percent.
Waste heat from electricity production in the cogeneration system is used to generate heat and cooling. As a result, the trigeneration system efficiency is much higher than that of a conventional energy supply system, where electricity and heat, as well as cooling, are generated separately.
As shown in the graph, over the last nine years, the combined operations of the EVC I and EVC II facilities have avoided more than 173,000 MTCE of greenhouse gas emissions when compared to emissions from a conventional energy supply. In 2006 alone, avoided greenhouse gas emissions from the combined operations of both cogeneration plants were estimated at 43,500 MTCE. This is more than the annual electricity-related emissions from 87,000 average-sized German households.
 AMD is a proud supporter of Plug-In-Partners, the national initiative to demonstrate demand for flexible-fuel Plug-In Hybrid Electric Vehicles (PHEV).
Other significant efforts include:
- In 2006, AMD Dresden engineers installed variable frequency water pumps for hot and cold water used for heating and cooling at AMD Fab 36 were optimized for even lower flow conditions that previously could not be handled efficiently. This is estimated to conserve approximately 150 MWh of electricity per year. Chemical Vapour Deposition (CVD) tool cooling water demand was optimized to adjust to actual tool needs, saving an estimated five percent of normal cooling water use per year.
- The AMD North American corporate campuses—Austin, Markham, and Silicon Valley—are planning to complete comprehensive energy audits in 2007. AMD Markham is in the process of replacing incandescent lighting with compact fluorescent lighting. The site has been racking the energy savings for each month for the bulbs replaced. Over 150 MWh annually were saved as a result of this change.
- The AMD Penang site installed a closed loop system for the die saw spindle and a vertical split case pump for chilled water and condenser water pumps. These two projects yielded electricity savings of more than 180 MWh in 2006 and will result in future annual electricity savings of 515 MWh. The AMD Penang team also applied a number of strategies for the new data center including server virtualization (consolidation of applications onto fewer servers), modular, scalable power and cooling architecture, more efficient air conditioning architecture, and more efficient floor layout. The new data center achieves annual electricity savings of 320 MWh, consuming only half of the electricity needed by the old data center.
- Singapore engineers changed the chilled water supply system to a variable chilled water supply system saving an estimated 1800 MWh of electricity per year. Adjustments to office temperatures and the installation of an outdoor temperature sensor used to adjust chilled water temperature for the air conditioning system are expected to yield annual savings of 240 MWh and 360 MWh, respectively.
