An effort has been made in this paper to identify whether there is any significant impact of environmental management information disclosure in adding value to a firm. This research is carried out on the basis of fifteen randomly selected listed banking institutions’ annual reports covering 2013 to 2017. The selected banks are enlisted under both the Dhaka Stock Exchange and Chittagong Stock Exchange. A disclosure checklist with 10 important categories of environmental management information is utilized to assess the magnitude of environmental management information disclosure. Using panel data regression analysis the finding indicates that the value of a firm is not significantly affected by environmental management information disclosure. This research work adds to the current body of knowledge by supporting the view that environmental management information disclosure alone cannot create firm value from the perspective of a developing country.
Environment Management Information Disclosure, Firm Value, Annual Report, Listed Banks, Panel Data.
The value of a firm depends not only on its performances but also on its capability to fulfill the demand of various stakeholders such as environment, employee and society (Sharma et al., 1999; Utomo et al., 2020). Careless behavior to the environment by organizations can create negative impact on the environment such as “Global warming, climate change, natural disaster, and water, air, and soil pollutions” (Utomo et al., 2020).
As a result, the demand for environmental information of companies has been increasing day by day all around the world since users of the information become increasingly conscious. Nowadays investors prefer profit maximization along with social and environmental welfare. Bangladesh is observing the bitter effects of global environmental pollution caused by huge carbon emissions and irresponsible industrialization (Redwanuzzaman, 2020). Apart from manufacturing organizations, banks and other financial companies are held indirectly responsible for environmental pollution since they provide fund to major industries (Hossain et al., 2016; Dhar & Chowdhury, 2021). Currently, the situation demands environmental pollution control measures in all industries including the financial industry (Redwanuzzaman, 2020).
Environmental disclosure presents information related to environmental initiatives, policy, strategy and implementation of the firm in the past, present and future (Utomo et al., 2020). An organization can disclose environmental information in various forms, including financial and non-financial statements, annual reports or footnotes (Al-Tuwaijri et al., 2004; Utomo et al., 2020). Realizing the importance of environmental disclosure for banking industry Bangladesh, like many countries, has formulated and issued mandatory guidelines known as ‘green banking disclosure’ (Bose et al., 2018; Khan et al., 2021). Green banking includes “online banking, less paper, mobile banking, green credit cards, green mortgages, environmental friendly projects through lowering interest rates etc.” (Dhar & Chowdhury, 2021).
Environmental disclosure practices in Bangladesh are not satisfactory compare to other countries (Dhar & Chowdhury, 2021). With few exceptions, maximum number of the previous studies concentrated either on disclosure nature and extent or on the determinants of environmental reporting (Sobhani et al., 2009). Moreover, a limited number of studies are based on environmental reporting practices of banking institutions (Dhar & Chowdhury, 2021). The topic ‘economic consequence of environmental reporting’ has been researched by a number of researchers (Montabon et al., 2007; Arafat et al., 2012; Saka & Oshika, 2014; Khan et al., 2021) but no concrete evidence has been found. It is necessary to identify the economic consequence of environmental management information disclosure in banking sector separately since it may help the bank managers to realize the importance of environmental management and thus encourage them to adopt and implement environmental strategy and policy effectively and efficiently. Thus, an effort has been made in this study to identify the possible link between environmental management information disclosure and firm’s value in the context of the banking industry in Bangladesh.
Over the years, numerous researchers have conducted studies to ascertain the impact of environmental reporting on corporate value (For example, Montabon et al., 2007; Arafat et al. 2012; Saka & Oshika, 2014; Plumleea et al., 2015; Chang, 2015; Nor et al., 2016; Qiu et al., 2016; Nor et al., 2016; Chen et al., 2016; Masud et al., 2017; Li et al., 2018; Rakiv et al., 2019; Yang et al., 2020; Dhar & Chowdhury, 2021). Some recent studies related to this particular issue have been discussed below.
Masud et al. (2017) examined the level of environmental disclosure practices by listed banking companies in Bangladesh. The sample consisted of 20 banks listed under the Dhaka Stock Exchange. Analyzing data of sample banks’ annual reports (2010-2014), the findings showed that the sample banks reported considerable amount of environmental details under selected headings in the annual reports and the reporting tendency increased sharply within the study period (from 16 percent in 2010 to 83 percent in 2014).
Rakiv et al. (2019) carried out a study to measure the correlation between environmental reporting and firm’s performance. This study was based on annual reports. The sample included each manufacturing firm listed under Dhaka Stock Exchange. To measure the environmental reporting, an Environmental Accounting Reporting Disclosure Index of 21 major environmental disclosure items was used. On the other hand, Return on Asset was used to measure firm’s profitability. Using descriptive analysis, ANOVA, and regression analysis, the findings show that only 41 of 166 companies disclose environmental information. Moreover, environmental reporting is positively associated with firm’s profitability.
Yang et al. (2020) undertook an empirical study in china to determine interrelation between environmental reporting and firm’s valuation. To accomplish this objective, listed manufacturing firms were taken as sample. The study period covers from 2006 to 2016. The study found that environmental reporting had significant effect on the listed manufacturing firms’ performance.
Gerged et al. (2021) investigated the influence of environmental reporting in case of firm valuation in the Gulf Cooperation Council countries. An un-weighted disclosure checklist of fifty five environmental information items was used to measure environmental disclosure level whereas Tobin's Q was used to proxy economic value. The findings from multivariate analysis support positive impact of environmental reporting on firms’ value. The employment of alternative measures such as ROA, weighted index, individual countries and environmental disclosure sub-indices also ensures the robustness of the main findings.
According to Hope (2003), one particular theory cannot give complete explanation of disclosure phenomenon. Thus, over the years, the researchers use a set of theories like agency theory, legitimacy theory, and stakeholder theory extensively to make clear the motives for environmental disclosure (Jaleel, 2018).
The agency theory states that enhanced reporting practices may reduce the information gap between management and shareholders (Jensen & Meckling, 1976) which in turn can reduce agency cost (Mak, 1991). For example, Huang et al. (2010) founds that increased environmental disclosure reduces the agency costs. Thus, to reduce agency cost and increase firm value a company can report environmental information (Jaleel, 2018).
Legitimacy theory is often used to explain the motive for environmental disclosure (Milne & Patten, 2002; Deegan et al., 2002). The theory claims that through legitimizing its activities a company tries to justify its existence in the society. In accordance with this theory, a firm utilizes information disclosure as a means to improve its communication to society so that it can manage social pressure and also establish itself a good corporate citizen (Guthrie & Parker, 2012). Some prior studies shows that environmental-friendly companies can substantially enhance their legitimacy to the environment by disclosing environmental information (Kuo & Chen, 2013) which can also lead to better financial performance and firm value (Barkemeyer, 2007).
The stakeholder theory states that a firm should be accountable not only to stockholders but also to various stakeholders. An entity should focus on stockholders’ interest as well as other stakeholders’ interest in case of firm value maximization (Utomo et al., 2020). Thus, it is not right for a responsible entity to attain its financial objectives at the cost of environmental pollution (Jensen, 2001). Many researchers have used stakeholder theory to interpret the reasons for making environmental disclosure (Sengupta, 1998). Through environmental reporting a firm can fulfill information demand of different stakeholders and establish its image as an environment responsible entity (Huang & Kung, 2010).
The prior literature shows variety of findings regarding the association between environmental reporting and firm value. While some studies provided the evidence of positive relationship (for example, Montabon et al., 2007; Saka & Oshika, 2014; Plumleea et al., 2015; Chang, 2015; Qiu et al., 2016 and Dhar & Chowdhury, 2021), other studies provided negative relationship (for example, Chen et al., 2016; Li et al., 2018; Mathuva & Kiweu, 2016). In contrast, Arafat et al. (2012) and Nor et al. (2016) have reported no effect of environmental reporting on firm valuation.
On the basis of theoretical foundation and the findings of most of the previous empirical studies it is hypothesized that:
H1: High environmental management information disclosure is associated with high firm value.
Sample and Data Collection
The sample includes 15 banking companies listed under both the stock exchanges of the country (Dhaka Stock Exchange and Chittagong Stock Exchange).The sample banks are selected randomly. The study period covers five years from 2013 to 2017. The main source of data is secondary source comprising sample banks’ published annual reports. The collected data is balanced panel data in nature and total firm year observation is 75 (15 sample × 5 years).
Construction of Environmental Management Information Disclosure Index
Based on the previous research (for example, Cooke, 1992; Ahmed and Nicholls,1994; Masud et al., 2017; Dhar & Chowdhury, 2021), the unweighted approach has been used in constructing environmental management information disclosure index. In case of unweighted approach all the information items are given equal importance and equal weights. In the present study, ‘1’ is given to a bank for reporting a particular information item anywhere in the annual report, and ‘0’ is given for not reporting that particular information. The formula (Cooke, 1992; Dhar & Chowdhury, 2021) which is employed to calculate total environmental management information disclosure score is as follows:
Where, r = 1, if the item ri is reported
0, if the item ri is not reported
n= number of items
The environmental management information disclosure checklist used in the present study is compiled from Masud et al. (2017) with some modification. The checklist is presented in the Appendix 2.
Measurement of Variables
The study’s dependent variable is firm value and independent variable is environmental management information disclosure. Apart from independent variable, three control variables: size, age and leverage are used in this research. A lot of prior studies often used control variables in the regression model to control dependent variable (for example, Muhammad et al., 2015; Bhuyan, 2018; Dhar & Chowdhury, 2021). Various indicators are used in previous researches to measure these dependent, independent and control variables. Consistent with prior studies, Table 1 provides the measurement of study variables.

Model Specification
The following general regression model is developed to determine the impact of environmental management information disclosure on the firm value:
ROAit = β0 + β1EMIDSit + β2TAit +β3AGEit + β4LEVit +εit
Where,
ROAit = Return of Assets of Bank i at period t
β0 = The intercept
EMIDSit = Environmental Management Information Disclosure Score of Bank i at period t
TAit = Total Assets of Bank i at period t
AGEit = No. of years since establishment of Bank i at period t
LEVit = Debt to equity ratio of Bank i at period t
εit = Error term
In case of panel data, three models are often employed for hypothesis testing: Pooled OLS, Fixed-effect and Random-effect models. Since pooled OLS model has number of limitations such as generating understated standard errors and inefficient regression estimators (Johnston & DiNardo, 1997), it is decided to use either fixed effects or random effects model in the present study.
Based on the Hausman specification test (chi2(4) = 1.83; Prob > chi2=0.7675) it is decided to employ random effects model to test the hypotheses.
Descriptive Analysis
Table 2 presents descriptive statistics of research variables
Table 2 Descriptive Statistics |
||||
Variable | Minimum | Maximum | Mean | Standard Deviation |
---|---|---|---|---|
ROA (percentage) | .31 | 2.36 | 1.105 | .4322 |
EMIDS (ratio) | .40 | 1.00 | .828 | .1351 |
LogTA (million taka) | 11.54 | 14.25 | 12.277 | .4936 |
Age (years) | 12 | 40 | 20.533 | 7.4241 |
LEV (times) | 7.56 | 28.24 | 12.654 | 4.0802 |
Source: Researchers’ calculation based on secondary data
According to Table 2, the mean of ROA is about 1.1%. It also indicates that the mean of EMIDS is .83 and standard deviation is .1351, which indicates that listed banks of Bangladesh are disclosing most of the environmental matters and there is not much variability regarding this practice among sample banks. Age and leverage of listed banks have also broad ranges. Age varies between 12 years to 40 years while leverage ranges from 7.56 to 28.24.
Multiple Regression Analysis
Checking of regression assumptions
The assumptions of Multicollinearity, Homoskedasticity, and Serial Correlation have been tested before running regressions model. The VIF (Variance Inflation Factor) value ranges between 1.13 and 1.97. Since VIF value of all the independent variables are below 10, we can say that the data is free from multicollinearity problem. The results of Breusch-Pagan test (chi2(1) = 0.30; Prob > chi2=0.5845) indicate no heteroscedasticity problem. According to the results of Wooldridge test (F [1, 14] = 13.492; Prob > F=0.0025), the variables in the model are auto correlated.
The above results reveal that all the multiple regression assumptions are not fulfilled. In case of not satisfying the multiple regression assumptions, robust approach can be employed (Draper, 1988 as cited in Cooke, 1998; Das, 2015). Thus, random effect model with robust standard error has been used in the present study.
Hypothesis Testing
Table 3 presents the empirical result of random effect model.

The above results indicate that the model is significant at p<.01 and environmental management information disclosure score has positive but insignificant association with the firm value. Thus, hypothesis 1 is not supported which implies that environmental management information disclosure does not affect the firm value of a listed bank in Bangladesh. The finding of this study supports the finding of Arafat et al. (2012) who has also found that environmental reporting does not impact firm value significantly. On the contrary, this finding is not similar with the results of Saka & Oshika (2014), Chang (2015), Khlif et al. (2015) and Plumleea et al. (2015), who have found positive effect of environmental disclosure on firm value. The reason might be that environmental disclosure by listed banks has recently flourished in Bangladesh. As a result, it may not have gained much attention from the investors during their investment decision.
Sensitivity Analysis
To ensure robustness of the results, profit margin is used instead of ROA in the original model. Results regarding the robustness check are presented below.
Based on the Hausman specification test (chi2(4) = 34.24; Prob > chi2=0.0000) it is decided to employ fixed effects model to test the hypotheses. Since the VIF values are below 10, we can say that the dataset is free from multicollinearity. The results of Breusch-Pagan test (chi2(1) = 48.90; Prob > chi2=0.0000) indicate that the data suffers from heteroscedasticity problem. According to the results of Wooldridge test (F [1, 14] = 11.278; Prob > F=0.0047), the variables in the model are auto correlated.
The above results indicates that fixed effect model with robust standard error should be used. Table 4 shows the empirical result of fixed effect model.

EMIDS | 1391.739 | 1199.141 | 1.16 | .265 |

The above model indicates that the result is consistent with the study’s main finding. Therefore, the result seems to be robust.
The present research has conducted empirical tests to find out whether the value of a firm is affected by the environmental management information disclosure in case of listed banks. The result indicates that environmental management information disclosure does not affect the value of a firm significantly. The study has supported some previous studies’ findings to some extent. More extensive research is required in this context to reach final conclusion.
There are certain limitations to this study. At first, the study concentrates only on the listed commercial banks. Future researchers could replicate this study using samples from non-banking financial organizations to generalize the findings. Secondly, this study uses common accounting-based indicators, namely ROA and profit margin to capture firm value. Future researchers can use both accounting based and market based measures in measuring firm value. Thirdly, the environmental management information checklist of this study is limited to only 10 items as compiled from Masud et al. (2017). More comprehensive index with vast area of environmental disclosure should be used in future studies as to capture environmental disclosure practices effectively and efficiently.
Nevertheless, in spite of some limitations we can say that the findings of this research has provided valuable insights in case of environmental management information disclosure especially in terms of the association between environmental management information disclosure and firm value across Bangladeshi banking companies.
