Energy

  • 13.0million gigajoules of energy consumed in 2018
  • 2.2percent decline in energy intensity

Most of our manufacturing processes are not energy-intensive, but we are committed to reducing our energy consumption to minimize our greenhouse gas (GHG) emissions, reduce costs and create more efficient facilities.

The Natural Resources and Climate Change Subcommittee of our Sustainability Committee oversees our energy-reduction strategy and actions. Key initiatives include:

  • Creating a culture of energy conservation through communication and awareness-building;
  • Developing a PPG standard for energy management based on based on ISO® 50001 and ENERGY STAR®;
  • Identifying and focusing resources on locations with the highest energy use;
  • Sharing best practices across the organization;
  • Exploring partnerships with energy solution firms; and
  • Increasing our use of renewal energy.

To reduce energy use, we follow the seven steps of the U.S. Environmental Protection Agency’s Energy Star Guidelines for Energy Management:

These efforts are supported by an internal online site for sharing energy management training documentation, tools, resources and best practices. In addition, our tracking system helps us gauge performance on a timely basis.

The vast majority of our coatings are produced at ambient temperatures and pressures, meaning the production processes are not energy-intensive. The milling step is the most energy-intensive, and we are focused on making this step more energy-efficient. We are also shortening cycle times and making other changes to reduce the energy required to manufacture our resins, which we typically produce in reactors that may require heating or cooling.

Our locations 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.

In the past few years, our sale of energy-intensive businesses and several acquisitions of coatings companies helped us significantly lower our energy intensity through shifts in our product mix. Becoming a lower-energy-intensive company reduces our GHG emissions, energy costs and risk of being impacted by increased global regulation of carbon emissions.

We updated our long-term energy goals in 2018 to better reflect our current operations:

  • Reduce energy consumption intensity by 15 percent by 2025 from a 2017 baseline.
  • Increase renewable energy to 25 percent of total electricity usage exclusive of GHG reductions by 2025.

We consumed 13.04 million gigajoules of energy in 2018. Our energy intensity was 3.13 gigajoules per metric ton of production, a 2.2 percent decrease over 2017. While our direct energy intensity remained stable, we achieved a 5.3 percent reduction in our indirect energy intensity.

In 2018, 4.3 percent of our total energy consumed came from renewable sources. For electricity usage, renewable sources comprised 16.3 percent.

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. Changes to the 2017 baseline data from prior reporting reflect adjustments for acquired, divested and closed locations. Other data changes are due to the conversion of data from British thermal units to gigajoules.
