Greenhouse gas (GHG) emissions are one of the main causes of rising global warming and the technology and communication industry accounts for approximately 2% to 3% of worldwide greenhouse gas emissions. A substantial amount of greenhouse gases emitted by burning oil, fossil fuels, and other sources include CO2, methane, and NOx. It has become increasingly vital for major contributing industries to record greenhouse gas emissions throughout operations, as corporate GHG emissions have increased.

GHG emissions are generally classified into Scope 1, Scope 2, and Scope 3 emissions. Scope 1 emissions are direct GHG emissions that occur from sources that are owned or controlled by the company. Scope 2 (Indirect GHG emissions) accounts for GHG emissions from the purchased or acquired electricity. Scope 3 refers to the company's other indirect emissions beyond the company’s direct operations and occur in the company’s value chain, such as the upstream transportation and distribution, business travel and purchased goods and services.

Cisco, Mitsubishi, and Nokia are large technology companies with a considerable amount of greenhouse gas emissions.
