EFFECT OF ENVIRONMENTAL ACCOUNTING PRACTICES ON FIRM VALUE OF QUOTED OIL AND GAS FIRMS IN NIGERIA.

Nigeria's oil and gas industry boosts the country's economy but also poses environmental problems such gas flaring, oil spills, and ecosystem degradation. As a result, open environmental accounting is necessary to guarantee corporate responsibility. The study examined the effect of environmental accounting practices on firm value of quoted oil and gas firms in Nigeria. An ex post facto research design was employed in this study. All ten (10) oil and gas companies listed on the Nigerian Exchange Group as of December 31, 2024, make up the population. Ten (10) oil and gas companies were chosen as the sample size for this study, which uses a census approach to examine the entire population. The annual reports and accounts of ten oil and gas companies that were quoted on the Nigerian Exchange Group floor across a ten-year period, from 2015 to 2024, were used to create a panel of data. The random effect regression technique was used to evaluate the data. According to this study, economic accounting practices disclosure has a negligible beneficial impact on the share price of listed oil and gas companies in Nigeria, whereas environmental accounting practices disclosure has a large negative impact. According to this study, oil and gas companies should correctly identify, measure, and report environmental expenses related to their operations in order to improve their environmental accounting systems.
