Use a "______" for product analysis
product unit
The appropriate technique for evaluating the environmental impact of a design depends on the
answers to the following three questions:
What impacts do you care about?; What is the scope of the assessment? and What types of
metrics are appropriate for your purposes?
greenhouse gas
(GHG)
Five Categories of Impact
1. natural resource depletion,
2. air impacts,
3. terrestrial & aquatic impacts,
4. climate effects
5. human health.
"Depletion" means
That those resources are no longer available for further use in their highest-value forms.
A water "footprint" primarily refers to
The amount of fresh water being used or consumed which then must be processed back to its
fresh state (water quality issues are covered by other impact categories).

,Water is the only resource
That is both renewable and infinite.
Mineral deposits can't be
Renewed as once it's gone it's gone.
Land can also become unusable, or at least less valuable, due to physical changes such as
erosion.
True
Non-renewable natural resources.
Oil, coal, and natural gas
Burning fuels creates
Sulfur dioxide, nitrous oxides, hydroflouric acid, ammonia, and other acidic air emissions.
Emission of chlorofluorocarbons Abrivation
CFCs
hydrochlorofluorocarbons Abrivation
HCFCs
Halons, and methyl bromide Abrivation
CH3Br
Eutrophication occurs
When an overabundance of plant nutrients are added to a water ecosystem.
Carbon dioxide (CO2), methane (CH4), and other so-called greenhouse gases result
from burning fossil fuels accumulate in the atmosphere, trapping solar heat which in turn
increases the earth's average temperature.
cancer-causing agents
carcinogens
substances that can cause birth defects
teratogens
The second major consideration in assessing the sustainability of a product

, scope of analysis
Scope is usually described
by how much of its lifecycle is included in its impact assessment...
Raw Material Extraction
This includes the energy and other resources used to acquire the basic materials used in the
product, whether through mining ore, harvesting timber, extracting oil, etc.
Material Processing
Raw materials are converted into forms used for manufacturing during this stage. It covers the
processes required to make steel, copper, plastic feedstock, paper, gasoline, and the like.
Part Manufacturing
This stage covers single, or at least simple, part manufacturing. Common processes include
injection molding, metal stamping and machining, weaving, and milling.
In many cases, products need to be assembled using processes that go beyond the creation of
individual components. Because this is usually the first stage that brings together a disparate
assortment of materials (e.g., a plastic handle and a metal container), environmental impact
assessments significantly increase in complexity.
True.
Product Use
Any energy used, emissions generated, other resources affected directly by the product during
its actual use are counted during this phase.
End of Life
This usually means that the product is no longer usable, although there are many examples of
end of life coming before end of usability (e.g., paper cups). This stage is usually broken down
into three resulting streams: the fraction of a product being sent to landfill, to incineration, and
to reuse or recycling.
Transportation is not typically given as a lifecycle stage, since transportation legs actually occur
between each of the lifecycle stages, but it's an important consideration to account for in the
product's lifecycle impacts.
True
