Data from a sample of Canadian manufacturing plants was collected through a mail survey conducted between September and December 2007, following a procedure inspired by Dillman (2000). The plant was chosen as the level analysis because it is generally where many environmental issues are evaluated and operational decisions are implemented. Using the National Pollutant Release Inventory (NPRI) and the Canadian Scott’s Directory, a sample frame of 503 randomly selected plants with more than 100 employees in the North American Industrial Classification Systems (NAICS) codes 332–335.1 A total of 94 usable responses were collected from that effort, leading to a response rate of 18.7%. Out of 94 plants, 22 have reported that they had more than 250 employees. Unfortunately due to missing data in some questionnaires, the sample was reduced to 85 for this study.
