The studys purpose is to recognize the drivers of Environmental Information Disclosure (EID) for stimulating listed firms on the Ho Chi Minh City Stock Exchange to report environmental information voluntarily in their reports. The correlation testing and the logistic regression analysis method were employed to find out the incentive and disincentive factors of voluntary disclosure. As a result, the outcomes indicate a positive relationship between environmental sensitivity industry, profitability, the firms size and EID while a relationship between revenue growth, financial leverage, and EID indicate negatively. Besides, the study also fails to find the impact of the firms age and ownership type on the disclosing of environmental information.
