John,
Here are the first three I came across.
1) A representation of the effect human activities have on the climate
in terms of the total amount of greenhouse gases produced (measured in
units of carbon dioxide).
www.esd.rgs.org/glossarypopup.html
2) Carbon footprint is a measure of the amount of carbon dioxide or CO2
emitted through the combustion of fossil fuels; in the case of an
organization, business or enterprise, as part of their everyday
operations; in the case of an individual or household, as part of their
daily lives; or a product or commodity in reaching market. In materials,
is essentially a measure of embodied energy, the result of life cycle
analysis.
A carbon footprint is often expressed as tons of carbon dioxide or tons
of carbon emitted, usually on a yearly basis. There are many versions of
calculators available for carbon footprinting.
This is directly related to the amount of natural resources consumed,
increasingly used or referred to as a measure of environmental impact.
Carbon dioxide is recognized as a greenhouse gas, of which increasing
levels in the atmosphere are linked to global warming and climate
change.

3) A carbon footprint is defined as:
The total amount of greenhouse gases produced to directly and indirectly
support human activities, usually expressed in equivalent tons of carbon
dioxide (CO2).

Subject: [TN] NTC Carbon Footprint term definition
Does anyone have an exact definition of the term "carbon footprint"
It is in general usage in Europe to describe environmental impact, but I
would like to know if this describes the lifecycle impact of a
material/assembly on the environment and if so how is it measured i.e.
in
unit measures of non renewable resource etc.
Anwers appreciated.
(To be honest if someone asked me the definition without mentioning the
connection with the environment, I would have said it probably described
ground zero when the US caught up with Osama bin Laden)
