Purpose
The purpose of this study is to analyze the simultaneous effect of the regulation (non-financial information (NFI)- 254/2016) and the factors driving in (no)environmental disclosure (ED) and the reduction of greenhouse gases (GHG) of Italian companies.

Design/methodology/approach
The study is supported by the theory of legitimacy. The level of ED regarding GHG was measured for 125 Italian companies in 2018, the companies were selected from Commissione Nazionale per le Società e la Borsa di Itália, because those included in the list of companies in the Dichiarazione Non Finanziaria all date back to December 31, 2019. Using a scoring system and content analysis of their annual reports, through 20 criteria supported by the literature. The study explores variables of the current legislation, the effect of disclosure and no disclosure, and the influence of the shareholding structure, managerial shareholding, economic power and industry classification at the ED level. The analyses were carried out using structural equation modeling because the authors seek to understand the cause-effect relationship between aspects of legitimacy with dissemination on GHG emissions.

Findings
This study finds that NFI.

Research limitations/implications
The study is limited to understanding the effect of legislation on the level of mandatory disclosure in non-financial reports, and the Paris Agreement (voluntary) disclosure on GHG, so the choice of companies analyzed and the study variables are limited to companies that are required to publish non-financial reports, and the variables considered in the study take into account normative aspects and voluntary guidelines of the Paris Agreement. As implications, the results show that adherence to the Paris Agreement contributes more to the quality and comprehensiveness of the information than adherence to the European and Italian legislation (mandatory), which reinforces the understanding that even if the legislation has advanced, it is still soft regarding the quality of information on companies' practices regarding the reduction of GHG emissions.

Practical implications
The findings suggest that non-financial reports are being adopted by listed Italian companies, however, there is variation in the scope of the reports, especially on GHG. For companies listed in Italy, non-financial reports comply with Italian Legislative Decree 254/2016 (mandatory), however, the quality of information on GHG is improved when companies' reports have greater adherence to the Paris Agreement (voluntary).

Social implications
The results can encourage companies listed in Italy to incorporate NFI in annual reports based on the Paris Agreement, the global pact to reduce GHG emissions, thus building confidence in the capital market and society in general.

Originality/value
The findings contribute to the literature on non-financial reporting, the level of compliance with legal basis and international best practices, such as the Paris Agreement, providing empirical analyzes of non-financial disclosures in publicly available reports in Italy.
