PFC emissions | Energy
Not every climate-change mitigation strategy is appropriate for TI, and we must weigh each greenhouse gas (GHG) reduction decision by balancing sustainability progress against practical cost considerations. In 2011, we set an ambitious company goal to reduce GHG emissions per chip produced by 30 percent over the next five years. We currently focus our efforts on reducing emissions from two primary areas – perfluorocarbons (PFCs) and energy use – which make up the majority of our emissions.
PFC emissions
PFCs are a group of chemicals vital to semiconductor manufacturing that are also considered greenhouse gases. Our industry recognizes that although the volume of such chemicals used may be small, we are still obligated to find technically and economically feasible alternatives that further reduce PFC emissions while preserving product quality.
As part of a 10-year, industrywide voluntary memorandum of understanding with the U.S. Environmental Protection Agency (EPA), TI reported PFC emissions to the agency, supporting a 10 percent reduction of emissions from a 1995 baseline through 2010. The industry successfully achieved and far surpassed that goal.
TI has committed to helping the industry achieve a new goal, established in 2011, to reduce PFC emissions by 30 percent per amount of good product produced (based on surface area) by 2020.
We voluntarily report PFC and other GHG emissions to the World Semiconductor Council as part of the U.S. industry report. In addition, we report our performance to the Carbon Disclosure Project, a group of institutional investors that encourage private- and public-sector organizations to measure, manage and reduce emissions and climate-change impacts.
In addition, we report our U.S. GHG emissions to the EPA to comply with the mandatory reporting rule.
Energy
The production of energy generates carbon dioxide (CO2), a greenhouse gas. Because TI's manufacturing equipment consumes the most energy in its operations, the company amended equipment purchase and usage protocols to promote efficiency and reduce energy use where feasible.
In recent years, chiller optimization has saved thousands of megawatt hours of energy. The recovery of heat from water-cooling loops to heat building air has conserved a significant quantity of energy as well. We have a variety of other measures to reduce energy use in all aspects of our operations worldwide.
