Greenhouse gas emissions
Cummins has achieved dramatic reductions in
greenhouse gas emissions due in large part to a
structured approach to energy efficiency. From
the end of 2005 to the end of 2009, Cummins
has decreased its actual greenhouse gas emissions
by 167,000 tons.
Our reduction goal, however, is an intensity goal,
which expresses GHG reduction per unit of sales.
Meeting an intensity reduction goal is typically harder
during a period of declining sales, which occurred
during the economic downturn starting at the end
of 2008, as plants were not running at full capacity.
Still, Cummins has achieved a 19.4 percent GHG
reduction since base year 2005, and is on track to
meeting its 25 percent goal.
In addition to energy reduction, site specific
reduction initiatives through the Environmental
Management System have yielded performance
improvements relative to non-GHG emissions, as
well as in wastes generated and resources used.

These metrics have generally held steady in spite
of substantial increases in production and sales
from 2006 through 2008 coupled with an increasing
number of reporting sites each year.
The year 2009 saw sharply declining sales from the
prior year. Although 2009 sales totals were similar to
sales in 2006, total water use and waste placed in
landfills were substantially lower in 2009 — evidence
that the Company improvement efforts are paying
dividends beyond any reductions associated with
decreases in production.
Water use in particular has been cut in half over
the reporting time-frame. Although recycled materials
are difficult to trend for improvements due to the
various influences on materials used in product and
packaging, Cummins has well-developed recycling
programs in all 55 Environmental Management System
(EMS) sites and most other non-manufacturing sites.
Efforts at better management of packaging are being
implemented within Cummins’ supply chain, which
will contribute to efforts to minimize wastes generated
associated with company operations.
