follow:
3.1.2 Independent Variables
An independent variable is influences the dependent variable in either positive or negative way Sekaran, 2006. In this study, there are seven
independent variables. In previous chapter is explained each of independent variable. The independent variables in this study are consists of:
3.1.2.1 ISO 14001 certified Environmental Management System EMS
Measurement was determined by the quality of environmental management system. The rank of environmental management system and the
value of each rank were classified into 4 categories,

3.1.2.2 The Existence of Environment Function ENV_FU
Measurement was performed by assessing on how the position of environment functions in a company. The indicator is the existence of
environment function, either inside position in management hierarchy or outside the management hierarchy person responsible of environment activity. The
detailed explanation about the existence of environment function is in below table:

The Report of Environment Information in accordance with Global Reporting Initiative Version 3.1 GRI
This measurement was determined by the score of environment information that was disclosed by company, and be compared with score of
environment performance based on GRI version 3.1. GRI version 3.1 was used in this study as follows:

Source: Global Reporting Initiative, 2011 Score calculation of environment information reporting in accordance with
GRI version 3.1 had following steps:
1. Gave score for each item of disclosure by dichotomy. The companies were
given score 1 if they disclosed the item of information and score 0 if they did not disclose the item of information.
2. Score that was obtained by each company was summed for getting the total
score. 3.
Score calculation the report of environment information in accordance with GRI version 3.1 had the following formula:
