This research aims to examine (1) the effect of carbon emission disclosure on firm value, (2) the effect of good corporate governance on firm value, (3) the mediating role of financial performance between carbon emission disclosure and firm value, and (4) the mediating role of financial performance between good corporate governance and firm value. The research sample includes 43 mining, agro, and manufacturing firms listed in the Indonesian Stock Exchange over the 2015-2017 period. Carbon emission disclosure is measured by an indicator of the Global Reporting Initiative Series of Environmental Aspect. Good corporate governance is measured by the corporate governance score of shareholder rights, boards of directors, outside directors, audit committee and internal auditor, and disclosure to investors. Financial performance is measured by return on assets, while firm value is measured by Tobin’s Q. Data analysis uses the structural equation modeling. The result shows carbon emission disclosure and good corporate governance have no direct effect on firm value. On the other hand, financial performance mediates the effect of carbon emission disclosure and good corporate governance on firm value. It shows that higher carbon emission disclosure and good corporate governance are meaningless for the investor if they do not give any financial performance improvement.

This paper aims to provide a review concept regarding the relationship between corporate governance and corporate sustainability in Indonesia. This paper examines the mechanisms and guidelines for implementing good corporate governance. This research used the literature review method and explores some effective corporate governance principles such as transparency, accountability, responsibility, independence, fairness, and equality to achieve business sustainability in Indonesia’s setting. The results show that good corporate governance regulation in Indonesia has been improved, but the enforcement is still needed to be optimized because good corporate governance will positively impact corporate sustainability. Thus, sustainability requires more corporate innovation because sustainability is about how a company can create profits and value-added to society through corporate social responsibility (CSR) programs and how the company can contribute to the preservation of nature and the environment. In Indonesia, the board of directors, the board of commissioners, and the audit committees are positively related to CSR disclosure. Thus, leadership and management efforts are crucial. However, to comprehensively support the synergy of implementing good corporate governance, we need the role of the state, the business community, and society. This study provides important insights into the implementation of good corporate governance in achieving corporate sustainability in Indonesia.

The study attempts to examine the effect of the capabilities of banking companies, namely the dynamic and unique capabilities, on the implementation of GCG in Indonesia. The effect of organization capabilities on the implementation of GCG is essential since both of them can demonstrate the quality of the company's ability to compete and innovate. This study will also examine the influence of moderating variables, namely the fit and proper test. The methodology used in this study is the structural equation methods and using primary data with board of directors of commercial bank in Indonesia. The test results suggest the positive direct effect of unique capabilities on GCG. The findings show that the capabilities of the top management, both unique and dynamic capabilities, influence the implementation of GCG. Then, the variable of fit and proper test can also strengthen the relationship between them. Both unique capabilities and fit and proper test have a strong and positive impact on GCG. Meanwhile, dynamic capabilities have a negative impact on GCG even though it’s not significant and contradictive with earlier studies. In the context of the banking industry growth and sustainability, this matter is important to examine. Top management behavior in operating their organization is important to be investigated.
