^aStandardized betas reported. Number of observations: 237 for environmental practices and 231 for capital budget
^b** = p-value < .01; * = p-value < .05; ^† = p-value < .10
^cThe company and plant size were computed by taking the natural logarithmic transformation of the number of employees
^dThis is a dummy variable where 0 is Ontario and 1 is Quebec
^eThis is a dummy variable where 0 is a not ISO 14001 certified plant and 1 is a certified plant
