Two prominent social theories have been shaping the discourse of envir
onmental politics during recent years. Ulrich Beck's risk society theo
ry contends that conventional definitions of social class are losing t
heir significance in advanced nations due to the success of the welfar
e state in reducing economic scarcity. As societies transition toward
late modernity new social cleavages based on the distribution of envir
onmental and technological risks are gaining salience. Standing in con
trast is the theory of ecological modernisation originally advanced by
Joseph Huber outlining a hyper-rational strategy for correcting the e
cological flaws of contemporary production and consumption practices.
This paper introduces a typology that joins the two theories into a un
ified framework and suggests that the direction toward which a particu
lar society progresses will be conditioned by its predisposition to sc
ientific rationality. Due to increasing public endorsement of alternat
ive epistemologies, most countries will likely encounter great difficu
lty achieving ecological modernisation. (C) 1997 Elsevier Science Ltd.
