🌍 Business Model and Industry Outlook
Tenneco Clean Air India operates in one of the most critical and rapidly evolving sectors — auto components. With the Indian government’s emphasis on emission control, sustainability, and local manufacturing, demand for clean air and exhaust management systems is expected to rise steadily.
