In today’s society, environmental concern might be at a historical peak. 2778 companies in 60 countries have now acquired the Benefit-Corporation (B-Corp) Certification in attempts to demonstrate their environmental responsibility. The aim of the present study was to investigate the effects of implementing the B-Corp Certification in a USA automotive dealership on employee pro-environmental behavior and life satisfaction, with consideration of the moderating role of commitment to the B-Corp Certification. A within-group quasi-experimental design was used to investigate the effects of the certification over a 5-month period through self-reported measures. Thirty-three employees participated in this study. One-way repeated-measures ANOVA was conducted to measure differences in employee pro-environmental behavior before and after the implementation of the B-Corp Certification. Through bivariate correlations the relationship between employee pro-environmental behavior and life satisfaction was analyzed. Partial correlation was used to test the moderating role of commitment in determining the strength of the implementation on employee pro-environmental behavior. There was no difference between pre- and post-measurements of employee pro-environmental behavior. Commitment to the B-Corp Certification did not moderate the effectiveness of the implementation of the B-Corp Certification on employee pro-environmental behavior. Additionally, no relationship was found between pro-environmental behavior and life satisfaction. Finally, results are discussed within the context of industrial- and organizational(IO) psychology, as are the implications for future research and interventions aimed at increasingemployee pro-environmental behaviors.
