1.Firmsareinterestedinenvironmentalcostingbecausethecostsofcomplyingwithenvironmentalregulationhaveincreasedandbecauseimprovingenvironmentalperformancecanreducecostsandprovideacompetitiveadvantage.
2.Ecoefficiencyisthebeliefthatorganizationscanproducemoregoodsandserviceswhilesimultaneouslyreducingnegativeenvironmentalconsequences,resourceconsumption,andcosts.
3.Thesixincentives,orcauses,forecoefficiencyare
(1)customersdesiretobuycleangoods,
(2)betteremployeesandgreaterproductivity,(3)lowercostofcapitalandcheaperinsurance,(4)societalbenefitsandimprovedimage,(5)innovationsandsearchesfornewopportunities,and(6)costreductionsandincreasedcompetitiveness.
4.Anenvironmentalcostisacostincurredbecausepoorenvironmentalqualityexistsormayexist.
5.Thefourcategoriesofenvironmentalcostsareprevention,detection,internalfailure,andexternalfailure.Preventioncostsarecostsincurredtopreventdegradationtotheenvironment.Detectioncostsareincurredtodetermineifthefirmiscomplyingwithenvironmentalstandards.Internalfailurecostsarecostsincurredtopreventemissionofcontaminantstotheenvironmentaftertheyhavebeenproduced.Externalfailurecostsarecostsincurredaftercontaminantshavebeenemittedtotheenvironment.
6.Realizedexternalfailurecostsareenvironmentalcostspaidforbythefirm.Unrealizedorsocietalcostsarecostscausedbythefirmbutpaidforbythirdparties(membersofsocietybearthesecosts).
7.Fullenvironmentalcostingmeansthatallenvironmentalcostsareassignedtotheproduct,includingsocietalcosts.Fullprivatecostingmeansthatonlyprivatecostsareassignedtoproducts.
8.Functional-basedcostingmustfirstisolatetheenvironmentalcostsandassignthemtoanenvironmentalcostingpool.Next,apoolrateiscomputedusingdirectlaborhoursormachinehours(orsomeotherunit-leveldriver).Finally,therateisusedtoassignenvironmentalcoststoproductsbasedontheirusageofdirectlaborhoursormachinehours.Theapproachbreaksdownwhenthereisproductdiversitybecauseunit-leveldriverswouldnotlikelyreflecttheenvironmentalresourcesbeingconsumedbyeachproduct.
9.Activity-basedcostingfirstidentifiesenvironmentalactivitiesanddeterminesthecostofeachactivity.Next,activityratesarecomputed.Finally,environmentalcostsare
assignedtoeachproductbasedontheirconsumptionofindividualenvironmentalactivities.
10.Theenvironmentalcostperunitofproductsignalstwothings.First,itindicateshowmuchopportunityexistsforimprovingenvironmentalandeconomicperformance.Second,itisameasureoftherelativecleanlinessofproducts.The“moredirty”productsshouldreceivegreaterattentionthantheonesthatare“moreclean.”
11.Life-cycleassessmentisanapproachthatidentifiestheenvironmentalconsequencesofaproductthroughitsentirelifecycleandthensearchesforopportunitiestoobtainenvironmentalimprovements.
12.Theenvironmentallyimportantlife-cyclestagesofaproductareresourceextraction,productmanufacture,productuse,andrecyclinganddisposal.
13.Thethreestepsoflife-cycleassessmentareinventoryanalysis,impactanalysis,andimprovementanalysis.Inventoryanalysisspecifiesthematerialsandinputsneededandtheresultingenvironmentalreleasesintheformofsolid,liquid,andgaseousresidues.Impactanalysisassessestheenvi-
ronmentaleffectsofcompetingdesignsandprovidesarelativerankingofthoseeffects.Improvementanalysishastheobjectiveofreducingtheenvironmentalimpactsrevealedbytheinventoryandimpactsteps.
14.Life-cyclecostingimproveslife-cycleassessmentbyassigningeconomicconsequencestotheenvironmentalimpactsidentifiedintheinventoryandimpactsteps.Assessingthefinancialconsequencesallowscompetingdesignstobecomparedonacommonmeasure,allowinganenvironmentalrankingofcompetingdesigns.
15.ThejustificationforaddinganenvironmentalperspectivetotheBalancedScorecardisbasedontheconceptofecoefficiency.Ifecoefficiencyisavalidconcept,thenaddinganenvironmentalperspectiveislegitimatebecauseimprovingenvironmentalperformancecanbethesourceofacompetitiveadvantage.
16.Thefivecoreobjectivesoftheenvironmentalperspectiveare:
(1)tominimizetheuseofhazardousmaterials;
(2)tominimizetheuseofraworvirginmaterials;(3)tominimizeenergyrequirementsforproductionanduseoftheproduct;(4)tominimizethereleaseofsolid,liquid,andgaseousresidues;and(5)tomaximizeopportunitiestorecycle.
17.Minimizingtheuseofrawmaterialsisanenvironmentalissuebecausemanyrawmaterialsarelimitedinquantityandarenonrenewable.Forexample,onlyafiniteamountofpetroleumreservesexists.Thus,conserv-
ingtheiruseensuresthatfuturegenerationswillhaveaccesstothem.
18.Possiblemeasuresforminimizingthereleaseofresiduesincludepoundsoftoxicmaterials,cubicmetersofeffluents,tonsofgreenhousegasesproduced,andpercentagereductionofpackagingmaterials.
19.Agree.Assumingtheconceptofecoefficiencyisvalid,thenallenvironmentalfailureactivitiesshouldbeclassifiedasnonvalue-added.Theseactivitiesrepresenttheconsequencesofinefficientproductionapproaches,andadoptingmoreefficient
approachescaneliminatetheneedforthesetypesofactivities.
20.Designfortheenvironmentmeansthateffortsaremadetodesignproductsandprocessestominimizeenvironmentaldegradation.Thisapproachcoverstheentirelifecycleandaffectsproducts,processes,materials,energy,andrecycling.
21.Thevalueoffinancialmeasuresofenvironmentalperformanceiseasytoidentify:
