Decoupling natural resource use and environmental impacts from economic growth
x
A transition to a low carbon resource efficient Green Economy has become one of the leitmotifs of international efforts to evolve sustainable development in a rapidly changing 21st century.
Next year in Brazil, governments will meet again 20 years after the Rio Earth Summit of 1992 amid a landscape of persistent and emerging challenges and against a backdrop of recent and on-going crises that in part are being triggered by the way society manages or more precisely mismanages natural resources.
A Green Economy, in the context of sustainable development and poverty eradication, is one of the two central themes of Rio+20. It underlines that it is in the interests of all nations – developed and developing and state or market-led – to begin reducing humanity’s planetary impact in ways that reflect national circumstances.
This new report by UNEP’s International Resource Panel is an important part of this overall discourse and direction. It brings empirical evidence to bear on the levels of natural resources being consumed by humanity and the likely consumption levels if past trends are mirrored into the future.
Indeed, it suggests that such unsustainable levels of consumption could triple resource use by 2050 and it brings forward the powerful and urgent concept of ‘decoupling’ as a key action in order to catalyze a dramatically different path.
Decoupling at its simplest is reducing the amount of resources such as water or fossil fuels used to produce economic growth and delinking economic development from environmental deterioration. For it is clear in a world of nearly seven billion people, climbing to around nine billion in 40 years time that growth is needed to lift people out of poverty and to generate employment for the soon to be two billion people either unemployed or underemployed.
But this must be growth that prizes far more efficient resource management over mining the very assets that underpin livelihoods and our economic opportunities in the first place.
Overall the analysis suggests that over the coming decades the level of resources used by each and every person may need to fall to between five and six tons. Some developing countries are still below this level whereas others, such as India are now on average at 4 tons per capita and in some developed economies, Canada for example, the figure is around 25 tons.

Similarly,theEuropean Union(EU)in2005adoptedtheLisbonStrategyforGrowthandJobs,6whichgavehighprioritytomoresustainableuseofnaturalresources,andcalledupontheEUtotaketheleadtowardsmoresustainableconsumptionandproductionintheglobaleconomy.ThiswasfollowedbytheadoptionoftheEU’sThematicStrategyontheSustainableUseofNaturalResourcesunderthe6thEnvironmentalActionProgram(6thEAP).Thisstrategyhastheobjectiveofachievingamoresustainableuseofnaturalresourcesbyreducingthenegativeenvironmentalimpacts generatedbytheuseofnaturalresources whileensuringeconomicgrowth.TheStrategyrecognizesdecouplingofbothresourceuseanditsimpactsfromeconomicgrowth.

Inlinewiththisliterature,resourcedecouplingcouldbereferredtoasincreasingresourceproductivity,andimpactdecouplingasincreasingeco-efficiency.
Resource decoupling meansreducingtherateofuseof(primary)resourcesperunitofeconomicactivity.This‘dematerial-ization’isbasedonusinglessmaterial,energy,waterandlandresourcesforthesameeconomicoutput.Resourcedecouplingleadstoanincreaseintheefficiencywithwhichresourcesareused.Suchenhancedresourceproductivitycanusuallybemeasuredunequivocally:itcanbeexpressedforanationaleconomy,aneconomicsectororacertaineconomicprocessorproductionchain,bydividingaddedvaluebyresourceuse(e.g.GDP/DomesticMaterialConsumption).Ifthisquotientincreaseswithtime,resourceproductivityisrising.Anotherwaytodemonstrateresourcedecouplingiscomparingthegradientofeconomicoutputovertimewiththegradientofresourceinput;whenthelatterissmaller,resourcedecouplingisoccurring(seeFigure1.1).

2.1 Note on methodology
Whilemeasuringconsumptionofenergyresourcesisfairlystraight-forward,
1 From now on, for reasons of brevity and simplicity, we shall use the term “resources” to mean “natural resources”. Of course, economic activity is based on a number of different resources, apart from natural resources, in particular also on capital, labour, and knowledge.
2 The terms of reference for this working group did not include a focus on energy resources, as they are dealt with in many other contexts. We are aware that from several perspectives, the energy (or exergy) aspects of natural resources are crucial (Ayres & Warr, 2005; Smil, 2008), but the purpose of the task at hand is to illuminate other aspects of resource use that are often neglected.
seekingaconsistentmethodologyfordocumentingtheextentofuseofotherresourcesisarelativelynewfieldthatisstillunderdevelopment.
For material resources,suchamethodologyandsetsofindicatorshavebeendevelopedonlyrecentlyunderthetermof‘materialflowaccounting’(MFA),whichaccountsforallmaterialsusedineconomicactivities.Someapproaches(forexampleBringezuetal.,2004;Rodrigues&Giljum,2005)accountnotonlyfortheresourcesusedineconomicprocesses,butalsoforthetotalmaterialmobilizedduringtheextractionprocess(i.e.the‘totalmaterialrequirement’).Thisisclearlyjustified,astheseadditionallymobilizedmaterialsareresponsibleforsubstantialadditionalimpacts,thoughtheanalysiscanbecompromisedbydatareliability.Forconvenienceandclarity,thisreportwillfocusonmaterialsactuallyusedineconomicprocessesmeasuredintermsoftheirmass(metrictons),i.e.totalusedextraction.Asaruleofthumb,totalextractionisaboutdoubletotalusedextraction.TheMFAmethodologygeneratesaccountsinphysicaltermsthatareanalogoustonationalaccountingineconomicterms,andaccordingtothesamesystemboundaries(Eurostat,2001;Eurostat,2007).Thusityieldsdatathatsupportananalysisofdecouplingofeconomicactivityfrommaterialresourceuse.Untilnow,SERI(2008)istheonlydatasetpresentingtime-seriesdataonglobalmaterialsextraction,country-by-

Economy-wide material flow accounts for historical periods have been compiled for a growing number of individual countries. Most of these country-level case studies document historic trends ranging from several years up to several decades. Only very few studies include time periods before 1970 (see e.g. Matos and Wagner, 1998; Schandl and Schulz, 2002; Petrovic, 2007). Several attempts have been made to compile global country-by-country material flow accounts for recent years (Schandl and Eisenmenger, 2006; Behrens et al., 2007; Krausmann et al., 2008b).

As a result of these data constraints on water and land, the assessment of resource decoupling in this report will focus mainly on the use of materials as accountedforbyMFA.

2.2 The global dynamics of material resource use
The global use of natural material resources corresponds to the sum total of raw materials extracted. 4 At the beginning of the 21st century, estimates for the quantity of global raw materials extraction ranged between 47 and 59 billion metric tons (47–59Gt) per year (Fischer-Kowalski et al., 2011). At the global level, the amount of raw materials extracted is roughly equivalent to the global amount of raw materials then used in economic processes. On the level of individual countries, the materials they extract in their domestic territory (termed DE, domestic extraction) is not equivalent to their materials use, as they may export or import products for use.
Figure 2.1 shows global material extraction for the period 1900 to 2005 in a breakdown by the four major material classes: biomass, fossil energy carriers, ores and industrial minerals, and construction minerals. Total material extraction increased over that period by a factor of 8. The strongest increase can be observed for construction minerals, which grew by a factor 34, ores and industrial minerals by a factor of 27, and fossil energy carriers by a factor of 12. Biomass extraction increased only 3.6-fold. This comparatively low increase of biomass extraction, while the world population needing food had quadrupled, is mainly due to a substitution of biomass use for combustion by fossil fuels. For much of the 20th century, biomass had dominated among the four material types: in 1900, biomass accounted for almost three quarters of total material use. One century later, its share had declined to only one third. Thus on top of using more biotic renewable resources, the global socio-economic metabolism has

increasingly turned towards mineral resources.5
A major driver of the overall increase in raw material extraction and use is population numbers (Steinberger et al., 2010; Krausmann et al., 2008). The world’s, and each country’s, material use (called domestic material consumption, DMC) is tightly coupled to the number of inhabitants. This is plainly evident for food, for example, but it also holds true for other material resources that have become part of a certain material standard of life. Thus it is common to calculate metabolic rates, that is resource use per capita, as a fairly robust overall measure of material standard of living (see for example Krausmann et al., 2008; Behrens et al., 2007; Haberl et al., 2009). From another perspective, metabolic rates can be seen as the ‘material footprint’ of an individual person living by a certain country’s average level of consumption. These metabolic rates are by more than one order of magnitude different for different countries. For example, one person more in India means on average an additional 4 tons of resource use, while one person more in Canada means on average 25 tons more resource use per year.
While global resource use has increased eightfold during the course of the 20th century (Figure 2.1), average resource use per capita merely doubled (Figure 2.2). A global inhabitant in 2005 required somewhere between 8.5 (Behrens et al., 2007) and 9.2 tons (Krausmann et al., 2009) of resources annually, while a hundred years earlier the average global metabolic rate was 4.6 tons.

Clearlythe global average metabolic rate rests upon highly unequal metabolic rates across countries, varying by a factor 10ormore(Fischer-KowalskiandHaberl,2007).Accordingtoarecentanalysis(Krausmannetal.,2008),twokeyfactorsaccountformuchofthisvariation:development status(developingoremergentvs.fullyindustrializedcountrieswithconcomitantincome)andpopulation density.7Eachofthesefactors,lookeduponindependently,seemstoberesponsibleforroughlyadoublingofthemetabolicrate.Fortheindustrialcountries,thosewithhighpopulationdensity(amongthemmanyEuropeancountriesandJapan)haveanaveragemetabolicrateofabout13tons/capita,whilethosewithlowpopulationdensity(forexampleFinland,theUSAandAustralia)haveametabolicratetwiceashighandmore,althoughincomeandmaterialcomfortdonotsubstantiallydiffer.Thesamevariationcanbeobservedamongtherapidlyindustrializingcountries:whileamongthemthehigh-densitydevelopingcountries(suchasChinaandIndia)showedaveragemetabolicratesof5tons/capitaintheyear2000,themetabolicratesincomparablelow-densitydevelopingcountries(e.g.BrazilandSouthAfrica)weremorethantwiceashigh.It appears that densely populated areas and regions,

metalsandcountriesthatbelongtotheworld’smajorprovidersofindustrialmineralsandores.Today,depending on the metal concerned, about three times as much material needs to be moved for the same ore extraction as a century ago,with concomitantincreasesinlanddisruption,groundwaterimplicationsandenergyuse.Therefore,eveniftoday’sextractionisdonemorecarefullythanacenturyago,andevenifthereleaseofaggressivechemicalshasdeclined,nodataareavailabletosuggestthatthegrowthratesofenvironmentalimpactswilllagbehindthegrowthratesoftheamountoforesextracted.
Most of the environmental impacts of extraction and use of construction minerals occur only at a regional level.Allextractionactivitiesofthesemineralsleadtothedisturbanceofland,airandwaterecosystems.Futhermore,energyuseforextractionandtransportneedstobeconsidered.14Similarly,alargepartoftheprocessinginvolvestheproductionofconcrete,15%ofwhichinvolvescementthatisamajorsourceofCO2emissions(1kgofcementgeneratesabout1kgofCO2emissions).Duetothenormallyhighwaste-to-productratios,extractiveoperationsoftengeneratelargevolumesofwaste;similarly,attheendofthelifecyclehighvolumesofwasterequiredisposal.Therefore,manyEuropeancountrieshaveintroducedminingchargesoraggregateleviestoreducethedemandforprimarymaterialsandencouragerecycling(EEA,2008,p.25).Asmostoftheenvironmentalimpactsoftheextractionofconstructionmineralsareadirectfunctionoftheirvolume,oneshouldexpecttheirdynamicstobefairlyproportionaltotheamountofresourceextractionanduse,perhapswiththeexceptionofconcrete:loweringtheproportionofconcrete,andimprovingthetechnologyofcementproduction,couldbeapathwaytofurtherdecouplingofenvironmentalimpactfromresourceuse.
14 In Germany, for example, 45% of the tonnage of freight vehicles is consumed by aggregates, see Bundesamt für Güterverkehr. 2006.
Different considerations apply to impacts in the use phase of construction minerals, with impacts depending on what is being built, where and how it is being built, and possibly relate only weakly to the amounts of resources used. Byusingadditionalmaterialtoprovidethermalinsulationtobuildings,forexample,CO2emissionsmaybereduced.
2.3.4 ConclusionTheenvironmentalimpactsassociatedwithresourceusearemultifold,varybetweentheresourcesunderconsideration,15andarenotdocumentedinaquantitativefashionthatrendersthemaccessibletoastatisticalassessmentortarget-settingfordecoupling.Itappearsthat short term and local environmental impacts of resource use across the life cycle have been and can be mitigated in a way that allows for impact decoupling beyond resource decoupling.

18 http://www.unep.org/pdf/pcdmb_policy_01.pdf19 The year 2000 is used as a baseline, as it best reflects a metabolic
equilibrium that dominated the 25 preceding years (see Figure 1.2) and was mainly shaped by trends in the industrialized countries. In the years since, a new phase of growth can be observed that we chose to capture in the scenario part of our analysis, as according to more detailed data it is already due to a “catching up” process by major developing countries (such as China and India).

23 One should be aware that achieving a substantial reduction in resource use on an economy-wide per capita level is much more difficult than achieving substantial resource productivity gains within certain areas of production. For an overall “Factor 2”-reduction of metabolic rate, much larger resource productivity gains have to be achieved in some areas (cf. Weizsäcker et al., 1997 “factor 4”; or Schmidt-Bleek, "factor 10" cf. Hinterberger and Schmidt-Bleek, 1999; or “factor five” in, Weizsäcker, et al., 2009), while, for example, food supply can only be reduced by a much smaller margin.

Summary of a theory of socio-technical transition to sustainable development
A multi-level-perspective (MLP) provides a framework for “...understanding sustainability transitions that provide an overall view of the multi-dimensional complexity of changes in socio-technical systems” (Geels, 2010, p.495). The MLP is a three-tiered framework which consists of the landscape (macro), regime (meso) and niche (micro) levels.
The socio-technical landscape, or macro level, is considered as an external factor and it provides the greater structure for activities in a system. As it is external, it is out of the control of actors within the system and thus cannot be changed according to preference and is in relatively stable condition, adapting slowly according to indirect adjustments at a lower level. But the landscape by nature is unpredictable, responding to variations in macro-economic, environmental and social conditions (Tukker, 2005).
At the micro level are socio-technical niches, isolated protected pockets where creation, development and testing of radical novelties and innovations take place. These novelties are learning experiments that respond to changes or demands at both the meso and macro levels; while the isolation provides a mechanism for protection against other market products, niches are the starting points for change (Geels, 2002; Geels & Schot, 2007). Furthermore, niche innovations usually occur within a small network of actors who provide the financial and technical support for their realization.
The meso level, or socio-technical regime, represents the existing configuration of institutions, rules, culture and techniques, forming the set of practices, exhibiting dynamic stability carried out by social groups (Geels, 2002).
This stability is reinforced by the consistent reference to a particular regime – whether it is science, technology, economics, politics or culture – identified according to its function, which hampers the introduction of niche innovations. Geels and Schot (2007) argue that the meso level is deeply embedded within the ‘cognitive routines’ of engineers, policy makers, the private sector and even academic institutions, consequently inhibiting the entry of radical innovations onto the market.
Through the interaction of its three embedded interconnected and interdependent components, the MLP allows for the emergence of socio-technical transitions. Changes at the macro and micro levels exert pressure on the socio-technical regime, which can lead to a transition. At the micro level, small networks developing radical innovations exert upward pressure through a build up of internal momentum which weakens the barrier of the regime level; eventually ‘breaking through’ when sufficient and simultaneous pressure has been exerted from the macro level. This breakthrough or ‘window of opportunity’ is created via the mutual tension from the macro and micro levels which destabilize the particular socio-technical regime, allowing competition between new and existing regimes, be it technological, cultural, political, economic or scientific. These changes have the capacity to influence or change the landscape level, while the landscape and regime levels directly affect or influence the niche innovation level. While numerous radical innovations are necessary to resolve the ecological crisis, technological transitions occur via step by step processes as opposed to radical regime changes. Various niche innovations, when connected, can thereby accrue to a system transition.

4.1.1 The dynamics of global trade in economic (monetary) and physical terms
Overthepastfewdecades,internationaltradehasincreaseddramatically.Between1970and2006,worldwidetradevolumesinmonetaryunits(realterms)grewbyanaverageof7.2%eachyear.Comparedwith1970,in2006thevalueoftradewasalmostafactorof10higherformanufacturedproducts,2.3timeshigherforfuelsandminingproducts,andmorethan3timeshigherforagriculturalproducts(WTO,2008).

monetaryandphysicaltradeflowshasoccurred:tradeinmanufacturedproductswithahigherpricepertonhasgrownfasterthantradeinprimarymaterials.In2005,manufacturedproductsmadeuponly24%ofphysicaltrade,butcontributed74%totheeconomicvalue(Dittrich,2009).
Atthegloballevel,physicaltradeisdominatedbyfossilfuels,whichaccountedforalmost49%ofallexportsin2005.Biomassrankedsecondwithover20%,followedbymetals(18%),minerals(10%)andotherproducts(3%)(Dittrich,2010).
Intensifyingglobaltradealsoimpliesgrowingenvironmentalpressuresassociatedwithtradeactivities.Ontheonehand,theseincludedirectpressures,inparticularduetotheimpactsoftransportation.AccordingtotheIPCC’s4thAssessmentReport,by2004thetransportsectorcontributed13.1%tothetotalCO2-eqemissions.Ontheotherhand,theindirect(orembodied)environmentalpressuresareaugmentedwithgrowingtradevolumes.Accordingtorecentmodelcalculations,CO2emissionsembodiedininternationallytradedproductsaccountedfor27%ofthetotalenergy-relatedCO2
emissionsin2005,upfrom22%in1995(Bruckneretal.,2010).OtherstudieshavecalculatedthevolumeofCO2emissionsembodiedinglobaltradeat22%fortheyear2001(PetersandHertwich,2008a).Fortheissueofwaterconsumption,measuredbythe‘waterfootprint’indicator(ameasureofthedirectandindirectuseofwatertoproduceagood),totalwaterembodiedinglobaltradewasaround16%oftheglobalwaterfootprintinthe1997to2001period(HoekstraandChapagain,2007).Firstestimationsofmaterialextractionembodiedinglobaltradeareabout20%oftotalworld-widematerialextractionintheyear2000(Giljumetal.,2008).
Environmentalpressuresdirectlyandindirectlylinkedtointernationaltradethusmakeupasignificantshareoftotalenvironmentalpressures.Therefore,
differentresultsareobtainedwhenresourceuseandenvironmentalpressuresareaccountedforfromaproductionperspective(i.e.allocationtothecountrywherethepressureoccurs)versusfromaconsumptionperspective(i.e.allocationtothecountrywheretheproductisfinallyconsumed).Inestablishedinternationalaccountingsystems(suchastheGHGaccountsintheUNFCCCframework),production-basedsystemsarefarmorecommon,particularlyastheyallowforthesettingofclearsystemboundaries.However,inordertoproperlytaketrade-relatedeffectsintoaccount,complementaryconsumption-basedaccountingsystemsarerequiredatthegloballevel(seeforexamplePeters,2008).Suchadoublesystemofaccountscouldserveastheempiricalbasisfordevelopingoptionsforsharingenvironmentalresponsibilitybetweenproducingandconsumingcountries(Lenzenetal.,2007).
4.1.2 The economic structure of global trade
Fromaneconomicperspective,theglobaltradingsystemhasfourmajorplayers.TheEU-27(excludingintra-EUtrade)isthelargestexportingregionwitha15.9%shareofglobalexportsandan18.3%shareofglobalimportsin2008.Chinarankedsecondasexporter(11.8%)andthirdasimporter(9.1%),followedbytheUS,whichhelda10.6%shareofglobalexportsanda17.4%shareofglobalimports,andbyJapanat6.5%and6.1%,respectively.Halfofthevolumeofworldtradeissharedbetweenthesefourplayers(44.8%ofworldexportsand50.9%ofworldimports,WTO,2009).

integration into the global trade system, globalization has not benefitted all countries and individuals.
The degree of economic integration into the world market is one issue, the role played in the international division of labour is another issue. A main distinction that matters needs to be drawn between mainly trading in raw materials and trading in manufactured products.
Industrialized countries largely export manufactured products. This segment of world trade is characterized by high value added, is associated with employment and has various positive spin-off effects. Many developing regions, on the other hand, continue to rely strongly on the export of primary materials. Latin America earns almost 70% of export revenues from agricultural and mineral raw materials, more than three quarters of total exports of the Middle East are fossil fuels, and Africa
has the highest share in primary products (80% of exports, consisting of agricultural products, minerals and fossil fuels, see Figure 4.1).
However, this general pattern has some important deviations, as some industrial countries, typically those with a very low population density, also play a major role as exporters of primary products. Australia, for example, has significantly expanded its primary sectors (in particular, coal and iron ore) in the past few years in order to serve growing demand in Asian countries, notably China. Some 70% of Australia’s exports in 2008/08 were primary products (food, fuels, minerals), up from 57% in 2003/04 (Australian Government, 2009). More than 47% of Canada’s exports in 2008 were agricultural products, minerals or fuels, and the US, with 21% of its exports comprising primary products, is a major world market supplier of natural resources (WTO, 2009).

2 See Figure 2.1 for global material extraction, amounting to nearly 60 billion tons (60 Gt) in 2005, though the amount traded is considerably less; the precise amount is difficult to determine because an unknown amount of materials extracted are converted into manufactured goods that may also contain some imported materials.
3 Since the late 1990s the trade balance of the industrialized countries has become negative, which is due mainly to the rapidly-growing trade deficit of the US.

Theabove-citedWorldBankreportcomesaftermorethan20yearsoftradeliberalization.Africangovernmentshaveliftedprotectivetariffs,thusundercuttinglocalindustriesthatwereunabletocompetewithpricesofimportedgoods.Inthenameofincreasingtrade,theoppositewasachieved.AccordingtoChristianAid,“[t]radeliberalizationhascostsub-SaharanAfricaUS$272billionoverthepast20years.Overall,localproducersare

DespiteincreaseddemandforprimaryresourcesfromtheemergingeconomiessuchasChinaandIndia,the value of Africa’s primary resource exports are generally falling.ThisisparticularlytrueforagriculturalproductsthatdeclinedinabsolutevaluefromUS$15billionin1987toUS$13billionin2000.AccordingtoAksoyandBeghin(citedinBond,2006,p.61),non-oilexportingsub-Saharancountriessufferedfromdecliningtermsoftradefortheperiod1970–1997resultinginacumulativereductioninrevenuelevelsthatamountedto119%oftheirtotalactualGDPfortheperiod.Inotherwords,ifthetermsoftradehadremainedstable,thecombinedGDPofthesecountriesfortheperiod1970–1997wouldhavebeenmorethandoublewhatitwas,withalltheattendantpotentialdevelopmentbenefits(Bond,2006,pp.60–63).

1. Integration of five key thematic strategies
• create sustainable markets, give innovations a direction
• establish strong institutions, build partnerships and networks to foster the diffusion of existing GreenTech
• develop sustainable products (‘cradle to cradle-approach’)
• use the market power of the state as a consumer
• create new thinking through training and education (e.g. ‘Resource University’)
2. Integration of sectoral policies
• harmonize overlapping and target oriented policies – at least the Ministry of Economics, Ministry of Science and Education, Ministry of Transport and Buildings, and Ministry of Environment should cooperate
3. Integration across technology and product-development cycles
• integrate target oriented R&D to raise material and energy efficiency with Demonstration, Pilots and Market Aggregation (fostering diffusion)

ThereisbroadconsensusaroundtwoeconomicandsocialchallengesforSouthAfrica’sseconddecadeofdemocracy:
• howtoboostgrowthto6%andensureamoreequitabledistributionofwealth;
• howtoeradicatepoverty,withspecialreferencetotheMillenniumDevelopmentGoals.
Energy• Increase Energy Efficiency by 20–30%: boost Demand-Side Management fund, remove it from ESKOM control,
establish efficient decision-making system• Increase Renewable Energy supply to 30% of national requirements from large-scale wind, solar, wave and biomass
plants by Independent Power Producers using Feed-In Tariffs, and incorporate solar energy into all residential developments
• Promote solar roof tops: co-finance one million new houses with solar roof tiles and water heaters• Create financial incentives and terminate disincentives via price-mechanisms for investment in energy efficiency
innovations
Water and sanitation• Switch from building dams to sustainable ground-water exploitation and management (including storage and
aquifer replenishment)• Invest in reducing water loss from leakages to below 10% • Reduce domestic water consumption by 40% via mandatory use of water efficient household fittings, grey water
recycling and rainwater harvesting• Build neighbourhood-level plants that recycle grey water for toilet flushing, capture methane gas for energy
generation and capture nutrients for reuse in food production and greening• Invest in technology innovations to reverse the qualitative degradation of national water resources
Transport and logistics• Increase investments in urban public transportation systems, especially Bus-Rail-Transit • Shift long distance freight transport from road to rail• Reduce dependence on oil via a shift to electric cars, hydrogen and ecologically sustainable biofuels
Housing and social infrastructure• Eliminate housing backlog through construction of 5 million low-income houses with sustainable design and close
to centres of employment• Increase densities from 15–20 dwelling units/hectare to a minimum of 35–45 dwelling units/hectare via smaller plot
sizes, multi-story living, and neighbourhood designs that minimize private vehicle transportation• Implement municipal ‘green house’ regulations governing all private, public and social infrastructure
Local Economic Development (LED) infrastructure• Substantial investment in institutional development for LED as envisioned in the LED Framework for South Africa

The sustainability perspective means there now is a third challenge, and due to the adoption of the NFSD and LTMS, this is being recognized:
• how to decouple growth rates and poverty eradication from rising levels of natural resource use and waste (commonly referred to as ‘dematerialization’).
Many of South Africa’s leading scientists have for some time been saying that
economic growth policies are premised on incorrect assumptions about the health and durability of its natural resources and ecosystem services. Aligning economic policy with Section 24 (b) of the Constitution is not simply about preserving the environment. As other countries have experienced, it is also about preventing wasteful expenditures on avoidable system failures. But above all, it can also be about the creation of new opportunities for driving non-material forms of growth that improve quality of life for all, forever.

When goods are exported, their embodied energy is also exported while pollution is left in the producer country; when a country exports more goods than it imports, it may become a net exporter of embodied energy, or from the perspective of pollution trade, it suffers from an ecological deficit.

1. Air pollution control measuresRestructuring Energy Components: Natural gas supply increased from 1.4 billion m3 in 2001 to 4.7 billion m3 in 2007. A total of 16,000 coal boilers below 14MW and 44,000 coal cooking facilities were converted to natural gas. Renewable energies such as biomass, ground thermal and solar energy were promoted; the ratio of cleaner energy in total energy consumption increased from 45.4% in 2001 to 62% in 2007.
Vehicle Emission Control: (a) More stringent standards: Euro II, Euro III, and Euro IV Vehicle Emission Standards and relevant standards on vehicle fuels were introduced in succession. (b) Green Public Bus Fleet: over 10,000 old polluting public buses and 50,000 aged taxis were replaced. By the time of the games, all 20,000 public buses met Euro III emission standards, with 4,000 natural gas buses, the largest fleet of its kind in the world. (c) VOC control: all gas stations, oil tankers and depots in Beijing conducted oil and gas recovery renovation to reduce pollution generated in the fuel storage and refilling process. (d) Building attractive public transport: public bus and metro fares were reduced to attract the public; total mileage of the metro was extended from 40km in 2001 to 200km in 2008; 60km of surface BRT system is now in operation.
Industrial Restructuring: The economy was restructured and the regional development layout readjusted. Processes and enterprises with high energy consumption and heavy pollution were phased out. High-end industries such as new hi-tech industries and modern service industries have been promoted and the ratio of tertiary industries is now over 70% of total GDP. From 2000 to 2007, 200 polluting enterprises were closed, converted to other production or resettled. Beijing’s large-scale coal-fired power plants underwent desulphurization, dust-removal and de-nitrification renovation, making their emission performance levels among the best in the world.
2. Eco-conservationThree green eco-shelter-belts have been established in the mountainous areas, plains, and urban areas, with forest coverage at 51.6%, the urban green coverage at 43% and per capita green area of 48m2.
3. Water environment16.1 billion Yuan were invested in protection of drinking water sources, wastewater treatment and rehabilitation of urban water courses. With the completion of 9 sewage treatment plants, the sewage treatment rate reached 92% in 2007. There are 11 recycling water plants in operation, and 57% of urban water is reused.
4. Solid waste managementSorted collection of urban waste is promoted. Some 23 environmentally-safe disposal facilities have been completed. The waste collection rate in urban districts is 99.9% compared to 80% in suburban areas. Around 96.47% of industrial solid wastes are reused and recycled.
5. Regional cooperationTemporary measures were developed and implemented in cooperation with neighbouring cities and provinces to guarantee good air quality for the Olympic Games. Good air quality was maintained during the Olympic Games fortnight.

9.1 Recognizing limits
9.1.1 Limits of resources – lessons learned from oil crises
Inthebeginningofthe1970s,Japan’sdependencyrateonimportedoilwasmorethanthreequartersofTotalPrimaryEnergyRequirement(TPER).Twoworldoilcrisesin1973and1979causedsignificantshockstotheJapaneseeconomyandsociety.Pricesofgoodssoaredandnervousconsumersrushedintothemarkettosecuredailynecessities.Suchreactionscausedaviciouscircleofrisingpricesandshortagesofcommodities.Inthissense,itcouldbesaidthatJapaneseconsumersdidrecognizethe‘limits’ofanoil-dependenteconomy,thoughsomeoftheshort-termchaoticsituationsinthemarketwereobviouslyafunctionofincompleteinformation.
Industriesreactedtothecrisesbyinvestinglargeamountsofmoneytosaveenergyandimproveenergyefficiency.Thereweresignificantlevelsofdecouplingbetweenenergyconsumptionandeconomicproductionbymanufacturingindustriesduringthelate1970sandearly1980s.Whileoildependencyofnationalprimaryenergysupplyhasdecreasedgraduallytolessthanhalf,itisstillhigherthanthatofotherdevelopedeconomies.Energysavingandfuelswitchingasareactiontotheoilcrisesgeneratedfavourablesideeffectswithrespecttoairpollutionabatement.ForthereductionofSOxemissions,itistruethatimpactdecouplingsuchasfluegasdesulfurizationwassuccessful.Inaddition,reductionofoilconsumptionthroughenergy-efficiencyimprovementsandfuelswitchingtonaturalgasandotherprimaryenergysourcesalsosignificantlycontributedtoSOxreductions(MinistryoftheEnvironment,GovernmentofJapan,1992).Thesesuccessescanbetakenasanexampleofthecombinationofresourceandimpactdecoupling.

Basedonthisrecognitionoflimits,policiesfortransitiontoaSoundMaterialCycleSocietyhavebeenformulated.
9.2 Policy responses
InspiredbytheEarthSummitinRio(UNCED1992),theJapanesegovernmentenactedtheBasicEnvironmentLawin1993.ThiswasfollowedbyadoptionoftheBasicEnvironmentPlaninDecember1994.Thisplanoutlinestheoverallandlong-termpoliciesofthegovernmentinenvironmentalconservation.Initsforeword,theplanrecognizedmainstreamsocio-economicactivitiesasacommondrivingforcebehindvariousenvironmentalproblems:
“Thereisagrowingneedtoreconsiderourvaluesplacingtoomuchemphasisonthepursuitofmaterialwealth,andtheprevailingsocio-economicactivitiesandlifestylesmarkedbymass-production,mass-consumption,andmass-disposal.”
ItwentontoaffirmthatJapanesesocietymustchangetoasustainableonethatgenerateslittleburdenontheenvironment,whileatthesametimepromotinginternationalactivitiesforconservingtheglobalenvironment(GoJ,1994).
However,areviewconductedbytheOECDpointedoutthatdespitequiteadvancedandsometimesexemplarypolicies,thedecouplingachievedinthe1990shadnotbeensufficient(OECD,2002).CO2emissionscontinuedtoincreaseasdidanumberofpollutiontrends,mostnotablythoserelatedtotrafficandenergyuse.Remainingwastedisposalcapacitywasalsoreachingacriticalpoint.Thisledthegovernmenttotakefirmerstepstowardsestablishingasoundmaterialcyclesociety(SMC).Whileitsconceptuallinkagewiththepoliciesforalowcarbonsocietywasmadeatlaterstage,reductionofCO2hasyettobesufficientcomparedtothetargetofKyotoProtocol.ThiscasestudydoesnotundertakefurtheranalysisofenergyandCO2issues,butfocusesonmaterialcycles.Anexceptionistheso-called‘toprunner’approachforenergyconsumptionbyelectricalappliances.
9.2.1 Towards a sound material cycle society
Theterm‘Junkan-gata-shakai’(SoundMaterialCycleSociety)wasfirstcoinedin1991byanexpertcommitteeoftheJapanEnvironmentAgency(Moriguchi,2008).TheconceptofaSMCisfirmlyrootedin3Rprinciples.2Japan’scommitmenttoa3Rpolicyispremisedonagrowingrecognitionoftwofactors–first,thattheincreaseinwastegenerationandwastenottreatedinanenvironmentally-soundmanneriscontributingtoworseningenvironmental

Thus,theSMCsocietyisoneinwhichmeasuressuchasreducedwastegenerationandreducedextractionofresources,reuse,recycling,andappropriatedisposalhavebeenadvancedinabalancedmanner(Figure9.1).ThefirststepinbuildinganSMCsocietyis,therefore,tounderstandtheflowsofmaterialsintheeconomicsector,intermsoftheresourcesextracted,consumedanddisposedof.Thiswouldnotonlyenable

About the UNEP Division of Technology, Industry and Economics
• Humankind has witnessed phenomenal economic and social development in the past century. However, there are increasing signs that it has come at a cost to the environment and to the availability of cheap resources. Despite progress, there is still great disparity between the rich and the poor. The dilemma of expanding economic activities equitably while attempting to stabilize the rate of resource use and reduce environmental impacts poses an unprecedented opportunity and challenge to society. In this report, the International Resource Panel has sought to apply the concept of decoupling economic growth and human well-being from environmental impacts and resource use to address this challenge. The report provides a solid foundation for the concept of decoupling, clearly defining key terms and providing empirical evidence of escalating resource use. It shows that decoupling is already taking place to some extent, but is lagging far behind its potential. The scenarios show that we are facing a historic choice about how we use resources and the report scopes the potential of innovation, rethinking economic growth and the role of cities in building more resource efficient economies. Four case studies at the country level show how policy makers are implementing decoupling strategies. This report focuses on material resources, namely fossil fuels, minerals, metals and biomass and will be complemented by parallel reports of the IRP on land and soil, water, metals, cities and technologies to mitigate GHG emissions. These future reports will contribute to the International Resource Panel’s objective to build a better understanding of how to decouple environmental impacts from economic growth and improved human well-being. It is hoped that policy makers aiming to green their economies will greatly benefit from the contributions that the International Resource Panel is making through its work on decoupling resource consumption from economic growth.
