At the corporate level, "footprints are used to sum up the indirect environmental impacts that occur along a company's supply chains," says Tommy Wiedmann, a footprinting expert and associate professor of sustainability research at Australia's University of New South Wales.
Multiple factors likely contribute to the historical lack of a chemical footprinting framework, says Richard Liroff, an environmental policy expert and founder of the Investor Environmental Health Network, a shareholder advocacy group based in Virginia.
This can cause compliance issues with international footprinting
The new footprinting method is applied along the entire product life cycle.
The water footprint is then expressed as a unit called water-equivalent ([H.sub.2]Oe)--similar to the C[O.sub.2]e (carbon dioxide-equivalent) unit used in carbon footprinting.
Nonetheless, carbon footprinting is not so complicated nor expensive.
Governments have already raised the spectre of carbon footprinting biofuels as being arbitrary or random.
In a 1988 publication, the American Academy of Pediatrics (AAP) and the American College of Obstetricians and Gynecologists (ACOG) stated that "...individual hospitals may want to continue the practice of footprinting or fingerprinting, but universal use of this practice is no longer recommended."(2) Both organizations based their findings on studies that demonstrated that the majority of infant footprints taken by hospital personnel prove inadequate for identification purposes.
In contrast, the FBI continues to advocate and encourage footprinting infants at birth, believing that this process represents a reliable, expeditious, and cost-efficient method for establishing probable personal identity.
will become an issue for customers as they attempt to reduce their own carbon footprint.
attempts to discover how much greenhouse gas--not just carbon dioxide and carbon monoxide, but including also the others such as NOx, SOx, methane and refrigerant gases--can be attributed to an individual product, company or operation.
A trend towards higher household consumption per person also raises a key issue posed by ecological footprinting
-- namely the degree to which a given population is sustainable from its own, or the world's, resources.
On the other and more technical level, ecological footprinting
is a strategic management tool that measures human impact upon nature, measuring human resource consumption and waste assimilation against our available stocks of natural capital.
If we are to achieve real progress in Wales, then ecological footprinting
can help us achieve that.
