“Sustainability…is to create and maintain conditions under
which humans and nature can exist in productive harmony,
that permit fulfilling the social, economic and other
requirements of present and future generations.”
United States Environmental Protection Agency

Cumulative Energy
Demand (CED)
accounts for the consumption
of energy resources, namely
the total amount of primary
energy from renewable and
non-renewable resources.

Global Warming
Potential (GWP)
measures the potential
contribution to climate
change, focusing on
emissions of greenhouse
gases, such as carbon dioxide
(CO2), which enhance the
heat radiation absorption of
the atmosphere, causing the
temperature at the earth’s
surface to rise.

Photochemical Ozone
Creation Potential (POCP)
or summer smog, is the formation
of reactive chemical compounds
e.g. ozone, by the action of
sunlight on volatile organic
compounds (VOC) and nitrous
oxides (Nox)

Use of Net Fresh
Water accounts for the
consumption of fresh
water (e.g. feed water,
ground water, lake
water, river water,
surface water)

Eutrophication Potential
(EP) is the excessive
enrichment of aquatic or
terrestrial ecosystems with
nutrients, nitrogen and
phosphorous being the most
important, which may cause an
adverse shift in species
composition and biomass
production.

Acidification Potential
(AP) describes the
conversion of air pollutants,
such as sulphur dioxide (SO2),
into acids, which have a wide
variety of impacts (e.g. in
form of acid rain) on soil,
water, organisms and
materials.Leshan Buddha, a 234-foot-tall statue

province

Ozone Depletion Potential
(ODP) refers to the degradation
of the ozone layer due to
anthropogenic emissions, such as
chlorofluorocarbons (CFCs). This
allows a greater fraction of UV-B
radiation to reach the earth’s
surface, with potentially harmful
impacts on human health,
organisms and materials.
KEEP CALM and protect the
ozone layer

Abiotic Depletion Potential
(ADP elementary and ADP fossil)
Abiotic resources are natural
resources such as minerals, iron ore,
crude oil and wind energy. The ADP
elementary impact category
includes all non renewable, material
resources, while the ADP fossil
category includes all fossil
resources, including feedstock.
