As carbon regulation evolves and becomes specialized in addressing carbon reduction issues, stakeholders will demand that firms provide increased information regarding corporate climate change practices. This paper contributes to the international research that examines the relationship between environmental information disclosures and additional firm factors. To do so, we have conducted an empirical analysis of the relationship between the corporate climate change disclosure practices of firms listed in the Athens Stock Exchange and firm factors, such as size, profitability, leverage and activity sector. Our results indicate there is a significant positive relationship between size and increased corporate disclosures regarding climate change practices. However, no significant relationship is detected between profitability or leverage and corporate climate change disclosures. Copyright © 2014 John Wiley & Sons, Ltd and ERP Environment
