The study examined the effect of profitability and firm size on environmental reporting among listed environmentally sensitive firms in Nigeria. The study used 24 environmentally sensitive companies (12 industrial commodity companies, 2 natural resource companies, and 10 oil and gas companies) over the five-year period 2015-2019.

The results show that profitability has a positive significant impact on environmental reporting, which means that environmentally sensitive companies are rewarded by stakeholders for environmental responsibility, thereby increasing their ability to respond to environmental reporting. It turned out that payroll size has a negative and negligible effect on environmental reporting.
