This research investigates the correlation and effect Energy Consumption, Company Size, and Age on Carbon Emission among non-financial companies in Indonesia. Regression model was used in analyzing research data in the form of annual and sustainability reports of 121 Indonesian companies from 2018-2022. Findings reveal a significant positive relationship between Energy Consumption, Size, and Company Maturity with Carbon Emissions. However, Profitability, Solvency, and GCG do not have significant impact on Carbon Emissions. These results underscore the necessity for companies to implement appropriate policies and strategies to mitigate environmental pollution and enhance environmental performance. This research also highlights the ambiguity in the relationship between corporate environmental performance and company size, age, and financial indicators which can be addressed in future research.
