Compliance with green requirements is becoming increasingly important in assessing the performance of companies. The new CSRD legislation requires a wider range of companies to produce sustainability reports and their content is influenced by the EU's taxonomy regulation setting out the framework for sustainable finance. The disclosure of information affects the perception of companies' sustainability performance, which will affect their access to financial resources and development opportunities. The main question is, both in theory and in practice, how companies can comply with the legislation in the future. It is essential for the competitiveness of Hungary's food industry to keep pace with future environmental sustainability requirements, so we examined the sustainability reporting practices of the sector's key companies in terms of their contribution to the environmental objectives set out in the taxonomy regulation. The research fits well with the EU's overall green transition regulatory procedure and our study is gap-filling at macro-regional and sectoral levels. The sustainability reports were assessed by content analysis using a scoring method. The results show that the sustainability reporting practices of food processing companies in Hungary differ significantly. Furthermore, greater emphasis must be placed on reporting and the credibility of the reports to meet future expectations. Foreign-owned companies and companies with more than 500 employees attribute greater importance to reporting. In the food processing sector, the disclosure of information and data under the taxonomy objectives of mitigation of climate change, sustainable use of water and marine resources, and transition to a circular economy was most common.

To demonstrate that companies are operating in a sustainable way, in line with the European Green Deal and the Taxonomy Regulation, some companies have already produced sustainability reports. Agricultural companies should also be prepared for this reporting obligation, which can cause considerable difficulties for farmers, so it is assumed that this is not yet common practice. In this research, the sustainability reporting practices of agricultural and forestry companies in Hungary were assessed and analysed. The research sought to find out what the current reporting practices of these companies are and how prepared they are for future regulation. In this paper, the information provided by companies on their websites and after personal contact was analysed using content analysis. The qualitative information gathered was quantified using a scoring method. For evaluating the data, descriptive statistics and pairwise correlation coefficients were applied. It is concluded that although forestry companies publish some level of information and pay more attention to the disclosure of this type of information than agricultural companies, there is a slight gap in both sectors. Moreover, almost a fifth of agricultural companies do not have any information on their websites. This is likely to change in the future, as the sustainability reporting legislation will broaden the range of companies that are required to report, so improvements in this field are expected.
