Throughout this 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 believe this most 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 company and to ensure year-over-year 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 and GHG data are assured annually by a third party; the results of our 2018 assurance can be found here.
