Purpose: This study aims to examine the various climate change practices adopted by firms and develop a set of corporate indexes that measure the level of climate change corporate commitment, climate change risk management integration and climate change strategies adoption. Moreover, this study examines the relationship between the aforementioned indexes. The authors claim that there is a positive relationship between the adoption of climate change strategies, corporate commitment and risk management integration. The aforementioned indexes have been used to assess the largest companies in the oil and gas sectors.Design/methodology/approach: To assess this study’s sample companies, a content analysis of their carbon disclosure project (CDP) reports for the years 2012-2015 was conducted. Finally, weights were assigned to the content analysis data based on the results of a survey regarding the difficulty of implementing each climate change practice included in the respective index. The survey sample included climate change experts who are either currently employed in companies that are included in the Financial Times Global 500 (FT 500) list, or work as external partners with these companies.Findings: The present study results highlight the need for developing elaborate corporate indexes, as the various climate change practices have different degrees of difficulty regarding their implementation. Additionally, a general trend in adopting climate change strategies is observed, especially in the field of carbon reduction strategies, which mainly involve the implementation of low carbon technologies. Finally, a positive and significant relationship was found between carbon reduction targets, risk management integration and climate change strategies.Practical implications: Although international research has extensively examined the importance of managers’ perceptions on environmental issues as an enabling factor in developing environmental strategies, according to the results of our survey, corporations must go beyond top management commitment towards climate change to be able to successfully implement climate change strategies. Incorporation of climate change risk management procedures into a company’s core business activities as well as the establishment of precise carbon reduction targets can provide the basis on which successful climate change strategies are implemented.Originality/value: Most studies address the issue of climate change management in terms of environmental or sustainability management. Furthermore, research on climate change and its relationship with business management is mainly theoretical, and climate change corporate performance is measured with aggregate indexes. This study focuses on climate change which is examined from a five-dimensional perspective: top management commitment, carbon reduction targets, risk management integration, carbon reduction and carbon compensation strategies. This allows us to conduct an in-depth analysis of the various climate change practices of firms.

Internal audit has been acknowledged as the main driver of corporate disclosure which aims to increase the quality of financial information, to ensure the transparency in financial reporting and to increase the confidence between managers and shareholders. The need for developing strong governance structures has led many researchers to examine the new framework of corporate governance and to explore its relationship to the internal audit process. Regarding Greece, there is a lack of research evaluating the relationship between corporate governance and internal audit. This study examines the above relationship in companies listed in the Athens Stock Exchange. In the present research, internal audit is examined in terms of audit quality and the consulting role of internal audit, in order to highlight the new management-oriented and value adding scope of internal audit. Data was collected via a survey questionnaire methodology and was analyzed using regression analysis. The results show that corporate governance is positively associated to the consulting role of internal audit, to internal audit quality and to the audit committee.
