Rapid development in the country has increased pollution in several ways. Pollution is harmful to human existence. Sustainability explains meeting human needs without compromising the planet’s integrity. Companies can play a vital role in reducing pollution through decarbonisation, proper waste management, green production, green accounting, and mindful usage of natural deposits. Conventional accounting only provides information about the financial status of the company. Here, Environmental Accounting comes into the frame taking into consideration recording and reporting accounting information which includes sustainable strategies, practices, and procedures to safeguard the planet without affecting the firm's profitability. The study explores the contribution of environmental accounting on sustainable development taking case studies of a few Indian companies. Environmental accounting is not limited to business operations but it also includes people and the planet. The purpose of the study is to know what measures and practices are adopted by Indian companies to protect the ecology and how they are dealing with business operations that have a negative impact on the environment. This paper focuses on whether or not; sustainable practices are reflected on financial statements of the company. To know the effect on sustainability study looks into various types of companies to find the answers to various questions such as what type of companies have adopted and which type of companies should adopt environmental accounting. The study being descriptive and exploratory shows that few companies have taken seriously environmental degradation and pollution emitted by business operations and harmful impacts on human life. Transparency in practices and reporting and compliance with environmental laws can successfully implement environment accounting in a most effective and relevant manner.
