Ethics guidelines for professionals in the risk sciences are relativel
y recent. The need for accountability is recognized by many profession
als, and has led to the development of ethics guidelines, anchored in
organization-specific mission statements or sets of core values. Almos
t none of the professions' existing codes reflect on broader social co
nsequences such as concern for ecological integrity. The importance of
this consideration was recently noted in The Toronto Resolution where
ensuring ecological integrity was directly linked to professional con
duct. Guidelines are useful and necessary for professional development
and day-to-day functioning, but alone they are insufficient to ensure
that professionals learn about ethics and how to apply the guidelines
while simultaneously recognizing the broader social consequences of.t
heir professional pursuits. In the interests both of professional acco
untability, as well as concern for the seamless web upon which all lif
e-support systems depend, each profession needs an ethics infrastructu
re. This paper provides a comprehensive organizational infrastructure,
comprising a seven-step program-focusing more on process than on cont
ent-for the integration of ethics into professional life. A framework
for action is developed, integrating several operationalizable process
steps. Difficulties in raising professional awareness and introducing
an ethics infrastructure are discussed in the context of epidemiology
. Professional organization and consensus on core values are seen as l
aying the foundation for an ethics program. To implement a program, co
difying professional conduct in the form of ethics guidelines, establi
shing consistent procedures and review processes; and establishing eth
ics education and training, are essential. Furthermore, introducing in
centives to encourage ethical conduct, an ethics consultation service,
and ongoing oversight and commitment, are critical components for suc
cess. Its process goals would include ongoing review, education, disse
mination, and adherence to the professions' core values, into which co
ncern for issues beyond the narrow confines of professional pursuits w
ould be integrated.
