Systematic Technology Assessment is a scientific method to study the e
nvironment in the aftermath of past-time technical innovations and dra
wing conclusions for the prevention of damage in connection with futur
e technical projects. Different methods for Technology Assessment are
known: The reactive method which analyses alternatives to stop or limi
t pollution and unwanted side effects inherent to many technological p
rocesses currently in use. The innovative method which commences at a
very early stage, when it is still possible to rectify technical probl
ems in the research and development process. These methods are of grea
t significance for the chemical industry both with regard to the rehab
ilitation of existing pollution and the development of new products or
technologies. A basic problem in using Technology Assessment is the c
omplexity involved, since it is essential to foresee as many effects a
s possible with technical objects. Technology Assessment is utilized i
n administration as well as in science and the economy. It would be de
sirable for Engineering Societies to take part in influencing public o
pinion by forming commissions for Technology Assessment and engineerin
g ethics.
