Facility Energy Use and CO2 Emissions

Table A and Table C

Data have been adjusted to account for facilities that were closed, sold or new. This data does not include ACH.

Table B and Table D

Energy consumption and CO2 emissions per vehicle divides energy used or CO2 emitted by the number of vehicles produced. Averaging energy and CO2 emissions by the number of vehicles produced yields a somewhat imperfect indicator of production efficiency. When the number of vehicles produced declines, as it has since 2000, per-vehicle energy use tends to rise because a portion of the resources used by a facility is required for base facility operations, regardless of the number of vehicles produced. We believe that stable-to-declining per-vehicle energy use and CO2 emissions indicate that more efficient production since 2000 is offsetting the tendency of these indicators to rise during periods of declining production. This interpretation is reinforced by our Energy Efficiency Index, which focuses on production energy efficiency, and which has been steadily improving. Our Energy Efficiency Index target also has the effect of driving reductions in CO2 emissions. These data do not include ACH.

Table E

The Index is "normalized" based on an engineering calculation that adjusts for typical variances in weather and vehicle production. The Index was set at 100 for the year 2000 to simplify tracking against our target of 1 percent improvement in energy efficiency.
