The importance of sustainability in business and sustainability reporting in big corporations is increasing, especially in the listed companies. Information about incorporating ESG factors in business operations significantly influences decisions about investing, both from ethical perspective and to avoid potential risks. New Corporate Sustainability Reporting Directive was put into effect and it brought new issued European Sustainability Reporting Standards (ESRS). There are ten ESRS standards which are divided by ESG topics into enviromental, social and governance standards. ESRS standards are a mandatory reporting framework for all large companies, and the novelty they introduce compared to previous reporting methods is double materiality. This means that companies will report on the assessment of the impact of their operations on the environment and society, as well as on the impact of environmental and social issues on the company's operations. Atlantic Group is one of the largest joint-stock companies in the Republic of Croatia and as such is obliged to report on sustainability in accordance with the new ESRS standards. The aim of this thesis is to analyze the Annual Report for 2023 and conclude whether Atlantic Group implements sustainability goals, and to what extent.
