United Technologies Corporation

United Technologies provides high-technology systems and services to the building and aerospace industries. By combining a passion for science with precision engineering, the company is creating smart, sustainable solutions the world needs.

Trends in urbanization and population growth continue to require more sustainable products and behaviors. As a leader in green aviation, we’ve set the standard for fuel efficiency, emission reduction and lower noise with our new Geared Turbofan jet engine. As the world’s largest provider of building technologies, we’ve developed energy-efficient solutions for green buildings that can change how cities urbanize. As a leader of technologies that keep food safe and fresh for consumption, we see ways to extend food supplies while avoiding food waste to feed our growing planet.

We lead by example, implementing sustainable solutions in our offices and factories as we have been doing for almost 30 years. Since 1997, we’ve tripled the size of our business while reducing our water consumption by 57 percent and our greenhouse gases by 34 percent. For UTC, sustainability means we can do good for the planet while we do good for our employees, communities, customers and shareowners.
