2018 Climate Leadership Award Logo

Raytheon aims to combat climate change over the long term by setting ambitious goals, reducing greenhouse gas emissions and measuring results. Since 2002 we have set and achieved three goals for the reduction of greenhouse gas emissions and are currently pursuing our fourth goal — a 12 percent reduction from 2015 levels by the end of 2020.

Approximately 90 percent of Raytheon’s greenhouse gas emissions relate to energy use. As such, our primary strategy for decreasing greenhouse gas emissions is to consume less energy. 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 energy consumption. To this end, we have upgraded/optimized HVAC systems, installed energy-efficient measures in our data centers and server rooms, and installed LED lighting while making other changes to building infrastructure and equipment. We also monitor and track developments in alternative energy technologies, low-carbon energy solutions and other techniques for reducing greenhouse gas emissions.

Over the last 15 years, Raytheon’s greenhouse gas program has been recognized several times by the EPA, the Center for Climate and Energy Solutions and The Climate Registry. Most recently, we received an “Excellence in GHG Management” certificate in 2018 for our 2020 greenhouse gas emission reduction goal.

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 response earned us an “A-” score.



Approximately 90 percent of our carbon footprint comes from the energy we use. The largest source of greenhouse gas emissions is the electricity we consume for lighting and power. In 2018, greenhouse gas emissions from electricity represented 75 percent of the total emissions. Our second largest source — on-site natural gas combustion primarily for heating — accounted for 12 percent of our emissions Emissions from the use of industrial chemicals and refrigerants in our manufacturing processes accounted for 7 percent. Other sources of greenhouse gas emissions are identified in the previous graphic.

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

Raytheon is committed to reducing its greenhouse gas emissions. We have measured, tracked, reduced and publicly reported our greenhouse gas emissions for over 15 years.

We adhere to stringent greenhouse gas emissions 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.

In 2018, Raytheon recorded U.S. greenhouse gas emissions of 387,550 metric tons of CO2 equivalents. This breaks down into approximately 91,435 metric tons of scope 1 (direct) emissions and 296,115 metric tons of scope 2 (indirect) market-based emissions.

Over the last 10 years Raytheon reduced U.S. greenhouse gas emissions by 38 percent, cumulatively eliminating close to 1.5 million metric tons of CO2 equivalents. This is comparable to cutting off electricity to 255,000 homes for a year, or to taking 310,000 cars off the road for a year. Since 2015, we’ve reduced our U.S. emissions by 15 percent, exceeding our 2020 goal of 12 percent reduction. This performance reflects several factors, including sourcing electricity from power plants that have switched from coal to cleaner fuels such as renewables and natural gas. Raytheon has also reduced energy consumption since 2015 and has decreased the amount of greenhouse gas-containing chemicals and refrigerants emitted during manufacturing and testing processes.
