Climate change is one of the most widely debated issues in the world because of the rise in greenhouse gas emissions during the industrial revolution. Corporations contribute to this to happen. They publish Social and Environmental Responsibility Report to indicate their responsibility to the environment. This study aims at exploring how Corporate Social Responsibility (CSR) reporting, carbon emissions disclosure, and eco-efficiency applications affect value of the corporation.  Multiple linear regression analysis using SPSS 26 was to analyse the data. This study found that CSR has no relationship with firm value. Meanwhile, disclosure of carbon emissions substantially gives adverse impact on firm value. The same applies for eco-efficiency which reduces the firm value. These findings demonstrates that CSR, carbon emissions disclosure, and eco-efficiency have a significant negative effect on firm value computed by PBV. They evidently had little effect on especially the fluctuation of the company's stock price.Climate change is one of the most widely debated issues in the world because of the rise in greenhouse gas emissions during the industrial revolution.
