Emissions

  • 930,000metric tons of direct (Scope 1) and indirect (Scope 2) GHGs in 2018
  • 4.3percent decline in GHG emissions intensity

The composition of our air emissions is unique to each PPG facility due to the varying products produced and manufacturing processes used. For all emissions, we are focused on reduction through improved operating practices, product reformulations and, where necessary, emissions control equipment.

We are reducing our greenhouse gas (GHG) emissions primarily by lowering our energy consumption (see the Energy section).

Activities and investments we are undertaking to reduce our GHG emissions are related to replacing equipment, such as boilers, chillers and air compressors, in all of our operations. We are undertaking these replacements over time to optimize the impact, focusing on priority sites based on improvement opportunities and resources required to achieve those reductions.

Our goal is to reduce our GHG emissions intensity by 15 percent measured in total tons discharged by 2025 from a 2017 baseline. We achieved a 4.3 percent reduction in 2018.

We emitted 930,000 metric tons of direct (Scope 1) and indirect (Scope 2) GHGs in 2018, which is a 2.1 percent reduction from prior year.

Total intensity data include direct and indirect emissions. We report greenhouse gas as carbon dioxide equivalents for carbon dioxide, methane and nitrous oxide. Changes to the 2017 baseline data from prior reporting reflect adjustments for acquired and divested locations.

Greenhouse Gas Emissions

  Total Direct Indirect
2014 2.08 1.13 0.95
2015 2.02 1.04 0.98
2016 1.85 0.91 0.94
2017 0.95 0.39 0.56
2018 0.93 0.41 0.52

Our plants are not significantly impacted by emission- limiting and/or emissions reporting-based programs or regulations. In 2018, we had zero direct emissions that were covered under an emissions-limiting regulation or program. Changes to the 2017 baseline data from prior reporting reflect adjustments for acquired and divested locations.
