Our Environmental Aspects
A range of environmental impacts is associated with the manufacture and use of automobiles. A high-level view of impacts throughout our value chain is set out here.
Analyzing our Environmental Issues
As part of our commitment to comprehensive environmental management using the ISO 14001 framework, we have analyzed both our environmental aspects and potential environmental impacts. Environmental aspects is a term used in the ISO 14001 framework to denote elements of an organization's activities, products and services that can interact with the environment. Potential environmental impacts include any change to the environment, whether adverse or beneficial, wholly or partially resulting from an organization's activities, products or services. Local facilities use corporate lists of environmental aspects and potential impacts to identify and amplify those aspects that apply to their operations. We are incorporating ISO 14001 aspects into our overall Environmental Operating System (EOS) currently being rolled out globally.
Quantifying Environmental Burdens
To quantify the environmental aspects and the potential environmental burdens associated with them, we have analyzed resource use and emissions throughout the life cycle of many of our products. These analyses have been done in our research labs, by Ford of Europe's recycling experts and in cooperation with others in the industry. The stages of a vehicle's life cycle include materials production, parts fabrication, vehicle assembly, vehicle operation (including fuel production), maintenance and repair, and end-of-life disposal and recycling. While estimates vary depending upon the specifics of the vehicle analyzed, one cooperative, multi-industry analysis of a typical family sedan (a spark-ignited, gasoline-powered, Taurus-class family sedan weighing 1,532 kg) found that during its life cycle:
- 961 GJ of energy are consumed
- 21,000 kg of hydrocarbon are consumed
- 60,000 kg of CO2 are emitted
In that study, it was assumed that the vehicle was driven a total of 120,000 miles at an average metro-highway fuel efficiency of 22.8 mpg. The study also found that:
- Vehicle operation consumes 86% of the life cycle energy
- Vehicle operation generates 87% of the life cycle CO2
- Vehicle production generates 65% of the particulates and 34% of the life cycle sulfur dioxide
This is consistent with a recent review of life cycle studies, in which it was found that the operational stage generally accounts for 80 to 90 percent of the total energy consumption and carbon dioxide emissions of conventional gasoline-powered vehicles, depending on the vehicle's material composition, average fuel efficiency and lifetime drive distance.
For example, a recent ISO 14040-reviewed Life Cycle Assessment study of the Ford Galaxy and S-MAX confirmed the high-use-phase share for these impact categories. Other impact categories are mainly dominated by the mining and material production phase.
