As stewards of the environment we seek to engineer a sustainable future. We are committed to protecting the environment and conserving natural resources. We strive to reduce our environmental footprint through responsible resource management, implementation of innovative solutions and collaboration with stakeholders.

The percentage reductions are adjusted to reflect the merger, the spinoffs of Otis and Carrier, and the acquisition of Rockwell Collins.

Climate change and greenhouse gas emissions

Climate change and greenhouse gas emissions

Raytheon Technologies is helping combat climate change by reducing its greenhouse gas (GHG) emissions, enhancing energy efficiency and optimizing our manufacturing processes. We have measured, tracked and publicly reported our GHGs for the last 15 years, and have been recognized by numerous organizations for our commitment and performance.

Since 2015, our legacy companies reduced their GHG emissions by 18%. Over this time frame, we cumulatively eliminated 696,000 metric tons of carbon dioxide equivalent GHG emissions. This is comparable to the energy used in approximately 80,000 homes for a year, or to taking 150,000 cars off the road for a year.

The largest source of our GHG emissions relate to energy use at our facilities, such as electricity and natural gas needed for our operations and building heating and cooling systems. Reducing energy consumption is one of our primary strategies for cutting GHG emissions. 

We participate in the voluntary global greenhouse gas disclosure system called CDP (formerly Carbon Disclosure Project), and respond to their annual climate questionnaire. The CDP program is supported by over 500 institutional investors representing $95 trillion in assets. Our detailed response addresses issues of governance, climate strategy, climate risks and opportunities, greenhouse gas emissions, accounting methodologies and goals. It also addresses many of the disclosure elements of the Task Force on Climate Related Financial Disclosures (TCFD), which was formed by the Financial Stability Board in 2015.

Energy conservation

Energy conservation

Energy reduction is a cornerstone of our company’s environmental sustainability program. It advances our sustainability vision and helps us conserve Earth’s resources. Reducing energy consumption also reduces greenhouse gas emissions and other pollutants.

Over the last 20 years, our businesses have executed effective energy management strategies and implemented thousands of energy efficient projects – 1,200 in the last two years alone. These include switching to energy efficient LED lighting, installing state-of-the art building automation systems, upgrading central plant facilities, and making improvements to compressed air systems, motors and drives, as well as optimization of production processes.

Our energy consumption in 2020 was approximately 18 million gigajoules. This includes: purchased electricity, natural gas, purchased steam, hot water, chilled water, and other fuels such as diesel, gasoline and jet fuel. Raytheon Technologies has six sites that self-generate a significant amount of electricity from on-site co-generation plants. In 2020, 51% of the company’s total energy was from the electric grid.

Energy assessments are conducted periodically at sites worldwide to identify opportunities for improvement. Reducing energy also supports our financial goals of affordability and competitiveness.  We are a proud partner in the U.S. EPA’s ENERGY STAR® program and the U.S. Department of Energy’s Better Plants® program, both promoting strategic energy management, energy reduction and energy efficiency.

Renewable energy

Renewable energy

Renewable energy — also called green power — comes from renewable resources including solar, wind, geothermal, biogas and low-impact hydropower. Renewable energy protects health and the environment by producing electricity with zero carbon emissions.

Raytheon Technologies has 25 renewable electricity projects in the United States, Singapore, U.K., Poland, France and Mexico. Twenty of the projects are located on-site. In the last two years, we launched four on-site solar projects and four off-site renewable energy projects. In 2020, the company bought or generated 40,250 megawatt hours (MWhs) of renewable electricity.

The company continues to investigate ways to expand its involvement in the renewable energy market. In 2020, we completed two third-party renewable energy assessments and we are evaluating the recommendations.

The renewable electricity that we generated or purchased in 2020 represents 1% of the total energy that the company consumes, including natural gas, jet fuel and other fuels used during manufacturing and testing processes.

Water conservation

Water conservation

Access to sufficient, fresh and high-quality water is important for manufacturing, facility operations and employee sanitation and hygiene. It is also important to our suppliers and the communities in which we operate. Water supply risks are growing globally due to localized and recurrent drought, competition for water in water-constrained water sheds, climate change and municipal infrastructure limitations.

Reducing our water use reduces the risk of business disruption and serves to protect the precious resource. That is why we are setting another water reduction goal as part of our 2025 EH&S Sustainability goals.

Since 2015, our former companies reduced their water consumption by 23%. Over that time, we cumulatively saved 1.1 billion gallons of water. Over the last several years, we have completed hundreds of water reduction projects including cooling tower upgrades, wastewater treatment plant enhancements, installation of low-flow fixtures in our buildings, implementation of changes in our manufacturing processes and enhanced use of xeriscaping. Many of our sites implemented water best management practices that help cut water use. Two of the most effective have been leak-detection programs and accountings of how much water comes in and out of the site.

Waste reduction and recycling

Waste reduction and recycling

Between 2015 and 2020, our former companies reduced the amount of hazardous waste that they generated by 22%. Sites evaluated processes that generate hazardous waste and targeted them for reduction. Hundreds of waste reduction projects were implemented, large and small. Projects included process redesigns and optimization, as well as administrative controls to reduce waste generation. Sites involved employees and process owners to assist in identifying and evaluating waste reduction projects. In 2020, the amount of hazardous waste generated was 20,355 metric tons.

Much of our hazardous waste is ineligible for recycling and reclamation and instead requires treatment, incineration or some other manner of disposal. In 2020, 48% of the hazardous waste was recycled or reclaimed.

The company also targets nonhazardous waste, implementing projects to reduce the amount generated and increase the amount recycled and reused. The company has extensive programs to collect and recycle a wide variety of commodities, such as metal, paper, cardboard, wood, aluminum cans and plastics. We also expanded the number of sites that implement food composting from their cafeteria as a way to divert wastes from landfill and incineration.

In 2020, Raytheon Technologies had zero reportable spills of hazardous substances in an amount equal to or greater than the reportable quantity identified in the U.S. Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA). The company has stringent programs to manage and store chemicals and hazardous substances in a safe manner to prevent spills and other releases.
