The European Green Agreement currently has an impact, apart from other things, on the business environment and the system of reporting information on the business sustainability. To achieve the proper functioning of the common market, the institutions of the European Union adopt secondary acts that strengthen the competitiveness of the economy in the EU member states, strengthen the social market economy and the sustainable economic activities of companies. Secondary EU acts are an important tool for promoting common EU policies and activities. The objective of the scientific study is to clarify the process of introducing EU regulation related to sustainability with a focus on accounting aiming at improving reporting quality to augment comparability and reliability of information provided by businesses in Slovakia. The contribution of the scientific study is to open the discourse on European Sustainability Reporting Standards and to identify problem matters.
