The period of validity of Directive 2014/95/EU, which imposed on enterprises the obligation to present non-financial information in separate non-financial reports, the so-called ESG was aimed to check its effects, complementary regulations and actual actions in the environmental area. Numerous works have analysed various aspects of non-financial reporting in the context of the directive, including several on ESG reporting in relation to air pollution emissions. However, it has not been examined yet whether there is a relationship between the level of reporting and the effects of pro-environmental activities in the context of the impact of regulations on it. A research gap in this area was identified, and therefore, the aim of the paper is to examine how selected chemical companies in Poland adapt to the EU guidelines on ESG reporting in the environmental dimension and whether it has an impact on reducing their pressure on the environment. The research period is 2010-2022, and the three-stage study used a quantitative-qualitative methodological approach. In the first and third stages, descriptive statistics and time series analysis methods were used. The second one includes methods such as content analysis, case analysis, GES Risk Rating, and expert analysis. The research carried out made it possible to conclude on the impact of non-financial reporting regulations on the environmental pressure.
