LIFECYCLE IMPACT CATEGORIES
The environmental impacts listed below were assessed throughout the product’s lifecycle – including raw material extraction,
transportation, manufacturing, packaging, use, and disposal at end of life.
ATMOSPHERE
Global Warming
Potential refers to
long-term changes
in global weather
patterns – including
temperature and
precipitation –
that are caused
by increased
concentrations of
greenhouse gases in
the atmosphere.
Ozone Depletion
Potential is the
destruction of the
stratospheric ozone
layer, which shields the
earth from ultraviolet
radiation that’s
harmful to life, caused
by human-made air
pollution.

WATER EARTH
Acidification Potential
is the result of humanmade emissions and
refers to the decrease
in pH and increase in
acidity of oceans, lakes,
rivers, and streams – a
phenomenon that
pollutes groundwater
and harms aquatic life.
Eutrophication
Potential occurs when
excessive nutrients
cause increased
algae growth in
lakes, blocking
the underwater
penetration of sunlight
needed to produce
oxygen and resulting in
the loss of aquatic life.

Photochemical Ozone
Creation Potential
happens when
sunlight reacts with
hydrocarbons, nitrogen
oxides, and volatile
organic compounds,
to produce a type of
air pollution known as
smog.
Depletion of Abiotic
Resources (Elements)
refers to the reduction
of available nonrenewable resources,
such as metals and
gases, that are found
on the periodic table
of elements, due to
human activity.
Depletion of Abiotic
Resources (Fossil Fuels)
refers to the decreasing
availability of nonrenewable carbonbased compounds, such
as oil and coal, due to
human activity.
