ADI and its employees are committed to protecting the environment and the health & safety of fellow employees, customers, and the public.

Greenhouse Gas Emissions Reduction Practices


Greenhouse Gas (GHG) emissions that are generated directly and indirectly are categorized into “scopes” based on the source of the emissions. The Greenhouse Gas Protocol defines Scope 1 emissions as direct from sources owned or controlled by the entity, including emissions from fossil fuels burned on site. Scope 2 emissions are indirect emissions that result from generating electricity, heating, and cooling offsite but purchased by the entity. Scope 3 emissions are considered indirect and not owned or directly controlled by the entity, but that are related to activities. Examples of Scope 3 emissions include employee travel and contracted solid waste disposal.

Analog Devices, Inc. (ADI) emit perfluorocarbons (PFCs) from our wafer fabrication processes and carbon dioxide (CO2) from fuel combustion associated with power and heat generation. We report our GHG information from our manufacturing sites to the Carbon Disclosure Project (CDP).

We also track our indirect GHG emissions. We have set a target for electricity use, which is the primary source of our indirect emissions. We have not set a target reduction for overall Scope 3 emissions.

Specific Actions / Projects

The primary source of our GHG emissions are chamber cleans in plasma etch tools used in manufacturing. We require all newly purchased manufacturing tools and equipment to have low greenhouse gas emissions or feature abatement systems. Our EH&S and Process personnel continue to monitor and evaluate industry developments for continuous improvement.


Air Emissions – Scope 1: Analog Manufacturing Activities

Our scope 1 emissions have decreased significantly since the project to install tool-based abatement systems has been implemented.

Air Emissions – Scope 3: Analog Business Travel

Beginning in 2011, we started tracking our Scope 3 emissions, limited to business travel. In 2013, we had our Scope 3 data verified by a third party service provider. The observed increase in our Scope 3 emissions from 2011 is attributed to support customer requirements.
