Greenhouse Gas Emissions<br />

Greenhouse Gas List<br />

<strong>Cummins</strong>’ inventory includes CO 2, CH 4, N 2O<br />

emissions from electricity and fuel consumption,<br />

HFC emissions from refrigerant use, and CO 2 and<br />

SF 6 emissions from manufacturing process<br />

use. <strong>Cummins</strong> has no emissions of PFCs.<br />

Emission Source Identification Procedure<br />

The identification of GHG emissions sources<br />

and the accumulation of the related emissions<br />

data are supported by several functions and<br />

groups within <strong>Cummins</strong>.<br />

At the site level, support is often provided by<br />

the local HSE (Health, Safety and Environment)<br />

committees, environmental engineers, facility<br />

engineers, environmental consultants, and the<br />

business unit functional excellence leader for<br />

environment management. At the corporate level,<br />

the identification of GHG emissions sources involves<br />

input from the Safety and Environmental Council,<br />

Climate Steering Committee, Energy Efficiency Team,<br />

regional energy efficiency teams, environmental<br />

consultants, as well as support from state and federal<br />

regulatory agencies.<br />

Direct Sources<br />

Electricity use dominates as the most significant<br />

source of GHG emissions associated with <strong>Cummins</strong>’<br />

operations. In addition, as an organization that<br />

manufactures and assembles diesel engines and<br />

related components, a substantial portion of <strong>Cummins</strong>’<br />

overall GHG emissions are a direct result of the engine<br />

testing operations related to production and research<br />

and development. Many of the <strong>Cummins</strong> facilities in<br />

the various businesses employ processes that use<br />

natural gas-fired or electric industrial ovens or other<br />

heat treatments and related processes.<br />

The Energy Solutions Business (ESB) is a Business<br />

Unit of <strong>Cummins</strong> Power Generation that sells the<br />

natural gas & biogas-fueled generator sets as well as<br />
