PREFACE We are delightedto be invitedto prefacethis bookfor four reasons. First,because it sets a realistic and fair stage for the importantUNCED 1992 conference. Second, because it acknowledgesmuch more developmentis needc4 in the South. Third, because that needed developmentand growth must be accommodatedby the North. Fourth,burdensharing or reparation for the North's historicoveruse of globalenvironmental functions - both as source of natural resourcesand sinkfor wastes -- is firmlyaccepted by the almostentirely Northern authors. Ths is refreshing. We havenot been too encouragedby the North'sreaction to the Brundtlandreport overthe four yearssince its publication. Therefore,we warmly endorse the clearthinkdng expressed in this book The fact that two Nobel laureate economistsare amongthe auttors (Haavelmoand Thbergen)raise our hopesthat economistswill raise sustainability higher on their agendasfor serious work in the 1990X We ullyshare the authors'view that the transitionis urgentand we find their suggestionson howto achieveit to be senusble.Now the difficultpart, mustering the politcal will, is up to us and our UNCED'92 colleagues.

In particular,we greatly admire the Commission'sachievement in garneringpolitical consensus on the needfor sustainabledevelopment. We use this report as our springboard,although we are far less comprehensive.Of the four elemeatsof environmentalsustainability -- poverty,population, technology, and lifestyle-- we focus on only lifestyle,technology and population,with that order of emphasisreflecting our skills. Povertyis onlydealt with via our suggestionsfor a moreequitable intemational income distribution. We acknowledge,however, that povertyand alrs debt are for somecountries more pressingthan environment. Our aim is to followBrundtland's lead on the need for a rapid transitionto sustainability. We bolsterBrundtland's case for the transition,because we feel that the need for this transitionis not yet adequatelyrecognized. We thengo on to suggestspecifics of whatis neededto achievethe transition. We eaveto othtersthe more importanttask, namely how to implementthe transition; how to muster the politicalwill for changeswhich will be painful,but essential. We feel that understandingthe necessityand general direction of the transitionis a preconditionfor musteringthe politicalwilL All authorshave read and discussedeach other's chapters and havereached consensus that the contributionsincluded in thisvolume are not onlycompatible with each other, but alsomutually reinforcing. We collaboratedfist becausewe felt that we wereall alreadythinking along similar lines,judging from our previouswriting Andsecond, because we all feel stronglythat the nextstep for the transitionto sustainabilityis agreementon the implicationsof what Brundtlandadvocated. We have deliberatelyretained a certainoverlap between some chapters in an effort to stressthe notion that, irrespectiveof the directionfrom which the subjectis approached,the sameconclusion is reached. The conclusionis that economicactivity cannot proceed any longerunder the banner of "businessas usual." Specificallyit is no longertenable to makeeconomic growth, as conventionally nerceivedand measured,the unquestionedobjective of economicdevelopment policy. The old conceptof growth,which we designate"throughput growth", with it- relianceon an everincreasing throughputof energy and other natural materals cannot be sustained,and must yield to an imaginativepursuit of economicends that are lessresource intensive. The waywe undervaluenatural capital servicesand fail to account for natural asset degradation often means that we are impoverishingourselves while imagining that our economiesare growing. The new approach requiresa concertedeffort at remoldingconsumer's preferences, and steeringwants
