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.The need to reach Kyoto targets gave rise to the adoption of national and international climate change mitigation policies. These include putting a price on carbon emissions in the form of carbon taxes, mandatory process and product standards or by establishing carbon trading programs (Bebbington and Larrinaga-Gonzalez, 2008). As a result, GHG-intensive activity sectors will face direct regulation risks in the form of increased costs, related to their obligation, for example, to have GHG emission allowances matching the amount of their emissions. On the other hand, non-intensive business sectors will most likely face the indirect effects of climate regulation through increased energy prices, which could affect their production costs.These increased risks that companies face have caught the attention of various stakeholders, such as institutional investors, banks, accounting firms, governmental agencies, NGOs and consumers, who have been demanding information disclosure regarding the corporate climate change practices of firms. On the financial front there is evidence that institutional investors view climate change as a major source of risk (Solomon et al., 2011). Consequently, they have begun to pay more attention to the corporate climate change practices of firms and to demand information regarding corporate climate change mitigation policies. The reason why institutional investors insist on companies disclosing information, especially those belonging to GHG-intensive sectors, is that inadequate disclosure of climate change related risks could reduce an investor's ability to estimate a firm's performance and future cash flows (Venugopal et al., 2009). Indeed, scientific research on credit risk management has shown that by incorporating sustainability criteria in financial assessment of projects, for example, banks can not only lower the chances of having to deal with credit default cases but have also more chances of gaining an advantage against their competitors by improving their credit risk management assessment procedures (Weber et al., 2008(Weber et al., , 2010.This paper contributes to the discussion of enhancing climate change corpor...

This study explores the effect of environmental, social, and governance (ESG) performance on market value and performance in the context of mergers and acquisitions. We examine whether acquisition of targets with better ESG performance can help acquirers to increase their own ESG performance and whether the market values the increased ESG performance positively. Moreover, we explore whether the acquisition of targets with better ESG performance affects the market value of acquirers. For this study, we utilize a sample of 100 European mergers and acquisitions between 2003 and 2017, for which matching data on the ESG performance of both the target and acquiring firms are available. Our results show that the postmerger ESG performance of the acquirer increases following the acquisition of a target that has higher ESG performance than that of the acquirer in the premerger stage, whereas the postmerger market value of the acquirer increases following an increase in the acquirer's postmerger ESG performance in relation to its premerger ESG performance. Finally, we provide partial evidence of a positive relationship between the postmerger market value of the acquirer and the acquisition of a target with higher ESG performance than itself in the premerger stage.

Abstract:The purpose of this study is to explore the relationship between internal audit effectiveness, internal auditor's responsibility, training and fraud detection. During the last decade internal auditing has become an integral part of modern businesses since it is capable of detecting errors or offences which lead to fraud. In order to investigate the above relationship, we conducted a survey of companies listed in the Athens Stock Exchange. We used factor analysis to validate the survey instrument and to construct our variables measuring fraud detection, internal audit effectiveness, auditor responsibility and training. We used regression analysis to test for significance between the constructed variables. Our analysis shows that audit effectiveness, auditor responsibility and auditor training affect positively and significantly the detection of fraud. Our results highlight the importance of internal audit in detecting accounting fraud and the need of companies to invest on internal audit processes and training in order to achieve enhanced corporate performance. Finally, our research stresses the importance of internal audit and fraud detection for companies which operate in countries which are in a period of economic crisis.

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.
