2015 Sustainability Report



PPG’s facility in Valencia, Spain is a model for energy management.
Although most of our manufacturing processes are not energy-intensive, we are committed to reducing our energy consumption to minimize our greenhouse gas emissions, reduce costs and create more efficient facilities.
To reduce energy use, each of our sites follows the seven steps of the U.S. Environmental Protection Agency’s ENERGY STAR® Guidelines for Energy Management:
  • Step 1: Make commitment;
  • Step 2: Assess performance;
  • Step 3: Set goals;
  • Step 4: Create action plan;
  • Step 5: Implement action plan;
  • Step 6: Evaluate progress; and
  • Step 7: Recognize achievements.
Our goal since 2012 has been to reduce our energy intensity by 1.5 percent annually on a global, business and site level. We achieved this goal in three years because we have moved to a lower energy-intensive product mix. Our locations also have been successful in reducing their energy usage by following the ENERGY STAR guidelines and through the commitment of our people to reduce energy in the workplace, from turning off the lights to installing energy-efficient equipment.

Our energy intensity in 2015 was 5.2 million British thermal units (BTUs) per metric ton of production, an 8 percent decrease over 2014 and 23 percent since 2012. We also saw corresponding declines in our direct (11 percent) and indirect (4 percent) energy intensities compared to 2014.
Energy consumption directly impacts the amount of greenhouse gases emitted. To continue our progress in reducing our energy usage, we set a new goal in 2016 that calls for a 25 percent reduction in our greenhouse gas intensity by 2020 from a 2012 baseline.
We held an energy management training workshop at our Delaware, Ohio, site in June 2015 for 21 energy leaders from various strategic business units and a second workshop in December 2015 at our Springdale, Pennsylvania, location for another 10 energy leaders. The workshop uses both classroom and hands-on training to teach participants how to maintain an energy management process, conduct energy assessments and create action plans.
We established a more comprehensive internal online site in 2015 to share energy management training documentation, tools, resources and best practices among our locations. In addition, we implemented a more robust tracking system to help us gauge performance on a timelier basis.

Direct energy consumption is the amount of primary energy we combust on site. Our direct energy sources may include coal, natural gas, fuel distilled from crude oil, propane, biofuels, ethanol and hydrogen. Indirect energy refers to the energy we consume that is generated by external suppliers. We consume indirect energy through electricity, heat, steam and electricity generated from renewable energy sources, such as solar and wind.
