Greenhouse Gas Emissions


Raytheon is committed to help combat climate change by reducing our greenhouse gas emissions. We have measured, tracked and publically reported our greenhouse gas emissions for the last 15 years. 

We adhere to stringent greenhouse gas accounting standards and protocols including EPA’s protocols and The Greenhouse Gas Protocol published jointly by the World Resources Institute and the World Business Council for Sustainable Development.

Carbon Footprint

Approximately 90 percent of our carbon footprint comes from the energy we use. We track both our direct (scope 1) and indirect (scope 2) greenhouse gas emissions. Direct emissions come from sources we own or control and represent approximately 22 percent of our annual total emissions. The largest direct emissions come from the natural gas used to run our boilers and generators to heat buildings and power industrial processes.

The remaining 78 percent of our carbon footprint are indirect emissions from the off-site power plants that generate the electricity, heat or steam we purchase for our operations. 

A third party certifies our annual greenhouse gas emissions inventory each year in accordance with the ISO 14064-3 Standard on greenhouse gas accounting and verification.

Raytheon’s 2017 U.S. greenhouse gas emissions were 392,000 metric tons of CO2 equivalents. This breaks down into 86,000 metric tons of scope 1 emissions and 306,000 metric tons of scope 2 market-based emissions.

NASA’s Scientific Data System Supports Climate Change Research

Raytheon has worked with NASA since 1992 on its Earth Observing System Data and Information System. The system ingests and archives earth science data and makes it available to a growing international user community that includes earth scientists, educators, governmental agencies and the general public.

The data helps scientists research and forecast the potential impacts of climate change. The data also helps governments plan and respond to natural disasters, assess natural resources and understand Earth as an integrated system.

Raytheon developed and maintains the information system that manages more than three petabytes of scientific data collected from 19 instruments on 10 aircraft.

Raytheon distributes more than three terabytes of data per day to thousands of users from scientific communities around the world.

Reducing Greenhouse Gas Emissions

Between 2008 and 2015, Raytheon cut its U.S. greenhouse gas emissions by 28 percent, cumulatively eliminating a total of 789,000 metric tons of CO2 equivalents. This is comparable to the electricity used in 118,255 homes for a year, or to taking 168,950 cars off the road for a year.

Since 2015, we’ve cut our U.S. emissions by an additional 12 percent, driven by our 4.4 percent reduction in absolute energy consumption. We also reduced indirect emissions from our purchased electricity significantly, as many of the electricity power plants we use lowered greenhouse gas emissions by using less coal and more natural gas and renewable resources to generate electricity.

Climate Strategy

Climate Leadership

Because approximately 90 percent of Raytheon’s greenhouse gas emissions are related to energy use, reducing energy consumption is our primary strategy for decreasing greenhouse gas emissions and doing our part to combat climate change. We continually identify and implement energy efficiency projects.

Our energy team analyzes monthly energy data, conducts energy audits, shares best practices, identifies candidate energy projects and works together to reduce consumption. This includes upgrading/optimizing HVAC systems, installing energy-efficient measures in our data centers and server rooms and installing LED lighting and making other changes to building infrastructure and equipment.

We also set annual and long-term greenhouse gas reduction targets and report progress to senior management and the public. Over the last 15 years, Raytheon’s greenhouse gas program has been recognized by the EPA, the Center for Climate and Energy Solutions and The Climate Registry.

Most recently, we received an “Excellence in GHG Management” certificate for our 2020 greenhouse gas emission goal. We also monitor and track developments in alternative energy technologies, low-carbon energy solutions and other techniques for reducing greenhouse gas emissions.

We participate in the CDP (formerly the Carbon Disclosure Project) climate change questionnaire annually. This survey addresses issues of climate strategy, climate risks and opportunities, reduction projects, greenhouse gas emissions and accounting methodologies. Our thorough responses have earned us a place in the “Leadership” category for three consecutive years.
