Best Environmental Stocks in India for 2025

India is going through a big energy transformation. The country plans to reduce carbon emissions and increase renewable energy in a big way. By 2030, the government wants half of India’s electricity to come from non-fossil fuel sources like solar and wind power, and aims to reach net zero emissions by 2070.

This massive shift has turned attention toward environmental stocks — companies that focus on clean energy, sustainability, and eco-friendly growth.

For investors, these stocks aren’t just about making money. They represent India’s move toward a greener future and support businesses that care about the planet.
