United Technologies (UTC) is a diversified company that provides a broad range of high-technology products and services to the global aerospace and building systems industries. UTC’s commercial businesses are Otis elevators and escalators and UTC Climate, Controls & Security, a leading provider of heating, ventilation, air conditioning, fire and security systems, building automation and controls. UTC’s aerospace businesses are Sikorsky aircraft and the new UTC Propulsion & Aerospace Systems, which includes Pratt & Whitney aircraft engines and UTC Aerospace Systems aerospace products. The company also operates a central research organization that pursues technologies for improving the performance, energy efficiency and cost of UTC products and processes.

In April of 2020, UTC merged with Raytheon Companies to form Raytheon Technologies - a technology and innovation leader that is dedicated to the advancement of aviation, smarter defense systems, and the development of innovations that contribute to the advancement of space exploration. 

As a responsible corporate citizen, UTC committed to minimizing the adverse environmental impact of its products, operations and supply chain — and to providing a safe work environment for all employees.

At UTC, sustainability means profitable, responsible operations that don't compromise the environmental and economic health of future generations. UTC was among the first companies to set targets for reducing energy consumption, water use, chemical emissions and industrial waste. The company continued to set big goals for itself — and to achieve even bigger results.

In 2013, the U.S. Department of Energy recognized UTC for slashing energy consumption across its U.S. operations by nearly 30 percent between 2005 and 2012. UTC was one of five companies honored that year for achieving aggressive energy-reduction targets set as part of its voluntary participation in the DOE's Better Plants program. UTC has been a pioneer in energy conservation, and set its first energy reduction goals in 1997. Its latest goal, set in partnership with DOE’s Better Plants Challenge, focused on reducing its energy intensity by an additional 17.5% by 2020 from a 2013 baseline, which is equivalent to a 2.5% annual reduction.

UTC received a 2017 Better Practice Award for creating a multifaceted energy efficiency improvement program that has saved millions in cumulative energy costs.
