The mandatory implementation of CSR and ESG reporting systems has not been enthusiastically received by companies. Traditionally, the primary objective of most businesses has been capital growth, while environmental protection has often been perceived as a cost burden rather than a strategic priority. The absence of standardized reporting guidelines has contributed to inconsistent disclosures and instances of greenwashing, where sustainability reporting has become more of a public relations tool than a source of substantive data. The Corporate Sustainability Reporting Directive (CSRD) aims to enhance the clarity, consistency, and comparability of Environmental, Social, and Governance (ESG) disclosures. This directive introduces a new set of regulatory standards that will apply to corporations based in the EU and small and medium-sized enterprises (SMEs) and non-EU entities operating within the EU market. It emphasizes the importance of greater transparency, the principle of double materiality, and the mandatory integration of ESG considerations into business models and strategies. This entry outlines key changes brought by the CSRD, focusing on environmental indicators, the scope of applicability, and reporting obligations. A literature review is included to highlight contemporary research trends related to sustainable development and the evolution of ESG practices. It should be emphasized that ESG reports are not only a meeting place for companies, financiers, and lawyers. Due to their many aspects, they are also a meeting place for scientists involved in environmental issues. They aim to properly define indicators and study the impact of ESG reporting on the environment.
