We align our reporting with the Global Reporting Initiative (GRI) Standards at a core level. Our Sustainability Supplement focuses on our top material issues, as established in the upper right-hand quadrant of our Materiality Assessment.
For each material topic, our report features a topic page that outlines relevant data, our management approach and initiatives that illustrate our work in 2017.
A Note About Our Data
Throughout the report, we define our organizational boundary using the financial control approach. In 2014, we completed a corporate-wide review of Scope 1 and 2 greenhouse gas (GHG) emissions for all owned and leased assets using the Greenhouse Gas Protocol accounting standards. We feel this more accurately reflects the direct impact of our operational footprint. We report data from newly opened and acquired facilities as soon as valid data is available. For recently closed or sold facilities, the data is included for the time period a site was part of the enterprise and to ensure year-overyear comparisons remain consistent. As such events occur, baselines are adjusted to account for these operating footprint changes. As our data collection system continues to mature and improve, the environmental data we report improves in accuracy and expands in breadth. Data is presented in absolute and normalized (intensity) terms. Normalizing environmental and energy data to total revenue provides valuable insights into the level of eco-efficiency across our diversified operations and allows benchmarking against the performance of other industrial companies. Our safety data is normalized by the number of hours worked.
Our EHS data is assured annually by a third party and the results of our 2017 assurance can be found here.
