Greenhouse Gas Emissions

Greenhouse gas (GHG) emissions are one of the main causes of rising global warming. 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 upstream transportation and distribution, business travel and purchased goods and services.
