A statemment<br />

concer rning the rissk<br />

of fatal in njuries in the<br />

different industries therefore<br />

is not poossible.<br />

In orderr<br />

to relate thhe<br />

fatal injuries<br />

to the ttotal<br />

workin ng time and hence to thhe<br />

value added,<br />

the<br />

workingg<br />

time for eevery<br />

industry<br />

has to be available.<br />

For the reasons exxplained<br />

in the last<br />

paragraaph,<br />

values should no ot be drawnn<br />

from diff ferent sourc ces. So vaalues<br />

from different<br />

tables, generated based on th he source mmentioned<br />

above on non-fatal n annd<br />

fatal injuries,<br />

are<br />

used: TThe<br />

total woorking<br />

time for each inddustry<br />

is de erived from the non-fattal<br />

injuries rate and<br />

from thee<br />

absolute nnumber<br />

of non-fatal n injuries.<br />

The soccial<br />

profile ffor<br />

each ind dustry includdes<br />

the wo orking time in different qualification<br />

the non-fatal<br />

and the<br />

fatal inju uries, each related to one o Euro of f value addeed<br />

Prices forr<br />

<strong>GaBi</strong>-Flows<br />

For relaating<br />

the social<br />

data to o LCA proceess<br />

data, th he value added<br />

of eachh<br />

LCA proc cess has<br />

to be iddentified.<br />

Thhis<br />

is done by calculating<br />

the delta<br />

of prices<br />

between the output and the<br />

input floows<br />

of eachh<br />

process. Therefore, for all mate erials, intermediate<br />

prooducts<br />

or products, p<br />

as well as variouss<br />

energy fl luxes, whicch<br />

go in an nd out of processes, p prices hav ve to be<br />

determined<br />

and asssigned.<br />

Sin nce the prooduct<br />

prices s depend on n a dynamicc<br />

market, th he same<br />

referencce<br />

period ffor<br />

both the e prices annd<br />

for the identificatio on of the vvalue<br />

added d of the<br />

industriees<br />

should be selected d. In this ccase<br />

the calculation<br />

is<br />

made wiith<br />

annual average<br />

values oof<br />

the same<br />

reference e period. A foreign trade<br />

statistic is used to provide co onsistent<br />

price daata<br />

(U.S. CEENSUS<br />

BURE EAU 2002A, U.S. CENSU US BUREAU 2002B). 2<br />

For moost<br />

of the fflows,<br />

price es can be calculated regarding quantities and total value v of<br />

exported<br />

commodiities.<br />

In cas ses where tthis<br />

is not possible, p pr rices are esstimated<br />

pe er expert<br />

judgemeent<br />

using tthe<br />

assump ptions that tthere<br />

are no n negative e value adddeds<br />

and th hat price<br />

ranges can be esttimated<br />

on the basis oof<br />

the lowe er price of a preliminaary<br />

product and the<br />

higher pprice<br />

of a suubsequent<br />

product. p This<br />

kind of es stimation ha as an impacct<br />

on the res sult if<br />

1. tthe<br />

according<br />

flow pas sses from onne<br />

industry into anothe er industry aand<br />

2. tthe<br />

social pprofile<br />

of bot th industriess<br />

3.11 VValue<br />

Addded<br />

of GaB Bi-Processses<br />

In orderr<br />

to calculatte<br />

the value added of a single proc cess, the to otal value off<br />

the incoming<br />

flows<br />

is subtrracted<br />

fromm<br />

the total value of thhe<br />

outgoing g flows of a process. The total value is<br />

calculatted<br />

by multiplying<br />

the amount of the flow wi ith its price and then bby<br />

summing g up the<br />

values oof<br />

all flows.<br />
