Improving resource productivity contributes to economicgrowth and to the reduction of pressures on theenvironment. The OECD puts resource productivity ina welfare perspective. It is understood to contain botha quantitative dimension (e.g. the quantity of output

produced with a given input of natural resources) anda qualitative dimension (e.g. the environmental impactsper unit of output produced with a given natural resourceinput).

Overview

Establishing a resource efficient economy is central to achievinggreen growth. It involves improving resource productivity and

putting in place policies that ensure a sustainable resource and

materials management building on the principle of the 3Rs

reduce, reuse and recycle, and encouraging more sustainable

consumption patterns. Better resource productivity helps to

improve the environment, by reducing the amount of resources that

human economic activity requires and diminishing the associated

environmental burden. It also helps to sustain economic growth by

securing adequate supplies of materials, improving competitiveness

and fostering new technologies and innovation.

To be successful such policies need to founded on a good

understanding of the material basis of the economy, of international

and national flows of materials, and of the factors that drive

changes in resource use and productivity over time, across countries

and in the different sectors of the economy. Some natural resources,

such as water, energy, forests, are monitored internationally,

but information is insufficient to give an integrated view of how

minerals, metals, or timber flow through the economy throughout

their life cycle. In addition, little is known about how this affects the

productivity of the economy and the quality of the environment.

The OECD report Material Resources, Productivity and the

Environmentis a first step to fill some of these gaps. It describes

the material basis of OECD economies. It examines how material

resources flow between the economy and the environment, and

the factors that drive changes in resource productivity over time

and across countries. The report uses concepts and tools from

material flow analysis and accounting, and provides a factual basis

to help understand some of the key challenges and opportunities

associated with material resources and resource productivity in

OECD countries.

Natural resources provide essential raw materials, water and other

commodities to support economic activity, and are an important

source of income and jobs. As part of broader ecosystems, they

support the provision of ecosystem services climate regulation,

flood control, natural habitats, amenities, cultural services that are

necessary to develop man-made, human and social capital.

The use of materials from natural resources in economic activities

and the related production and consumption processes have many

environmental, economic and social consequences that extend

beyond the borders of individual countries or regions, and that affect

future generations. They have consequences on:

The rate of extraction and depletion of renewable and non-

renewable natural resource stocks, and the extent of harvest and

the reproduction capacity and natural productivity of renewableresource stocks.

The environmental pressures associated with the extraction,

processing, transport, use and disposal of materials (e.g. pollution,

waste, habitat disruption); and their impacts on environmental

quality (e.g. air, climate, water, soil, biodiversity, landscape), on

ecosystem services and on human health.

International trade and market prices of raw materials and other

goods.

The productivity and the competitiveness of the economy.

The way natural resources and materials are managed and used

all way through the economy is thus important, not only from an

environmental perspective but also from an economic and trade

perspective.

Natural resources are

fundamental to the economyand human well-being

A development pattern that depletes the economys natural asset base

without providing secure, long-term substitutes for the goods and

services that they provide is unlikely to be sustainable.

The environmental consequences of the use of natural resources and

materials occur at different stages of the resource cycle and affect

the quantity and quality of natural resource stocks and the quality of

ecosystems and environmental media. The type and intensity of these

consequences depend on the kind and amounts of natural resources

and materials used, the way these resources are used and managed,

and the type and location of the natural environment from where they

originate.

Rising material demand presents

challenges and opportunitiesThe last decades have witnessed unprecedented growth in demand

for raw materials worldwide, driven in particular by the rapid

industrialisation of emerging economies and continued high levels of

material consumption in developed countries.

The amount of materials extracted, harvested and consumed

worldwide doubled since 1980, an estimated ten-fold increase since

1900; it reached nearly 72 billion metric tonnes (Gt) in 2010, and is

projected to reach 100 Gt by 2030. Growth has been primarily driven by

global demand for construction materials, fossil fuels, and biomass for

food.

At the same time, international commodity markets have expanded,

with increasing international trade flows, increasing mobility and

fragmentation of production factors, and expanding linkages among

countries and regions. This has been accompanied by increasing and

highly volatile commodity prices and by growing competition for some

raw materials.

Did you know

OECD countries account for:

Slightly less than half of the global economy

(using PPPs) compared to about 60% in 2005.

Less than one-third of all material resources

consumed worldwide compared to 43% in 1990.

Growing demands for

materials worldwide and

the globalisation of supply

chains change the ways

in which materials are

supplied to the economy

and raise concerns as

to the environmental

impacts of their use to

create opportunities for

Rising demand for materials affects the ways in

which natural resources are supplied to, and used

in the economy.

They raise questions about the sustainability

of natural resource use and the negative

environmental impacts of production and

consumption of resources, as well as about

risks of disruptions in materials supply.

As production and consumption have become

displaced with increasingly complex and

globalised value chains, questions also arise

about the distribution of the environmentalburden associated with material use.

By 2050, the world economy is expected to

quadruple and the global population to grow to

over 9 billion, placing additional strain on the

earths material resources and the environment.

A growing population with higher average income

requires more food, more industrial products, more

energy and more water. This creates formidable

economic and environmental challenges.

Confronting the scale of these challenges requires

ambitious policies to achieve a significant increase

in resource productivity, particularly through

technical change and innovation, and through

more effective management approaches. This will

in turn create opportunities for investment, for

new products and markets, and for employment.

Decouplingis breaking the

link between environmental

bads and economic goods.

Absolute decoupling occurs

when environmental degradation

or environmental pressures are

decreasing while the economy isgrowing. Decoupling is relative

when environmental degradation

or environmental pressures are

growing, but at a slower rate than

the economy



9/16

Material productivity is improving,

but decoupling remains weakMaterial extraction and consumption in OECD countries haveincreased, but much more slowly than at the global level. Material

productivity is improving and there are signs of decoupling of

material consumption from economic growth.

Today, OECD countries generate 50% more economic value with one

tonne of raw materials than they did in 1990 and 30% more than in

2000. The domestic material productivity of OECD economies rose

from 1400 USD per tonne in 2000 to over 1800 USD per tonne in 2011

(in constant prices and PPPs). Decoupling has occurred overall in theOECD area, across all material groups.

Progress in material productivity can be attributed

to policy action and technological change, as well

as to structural changes, including the rise of the

service sector and the substitution of resourceintensive domestic production by imported goods.

The economic slowdown following the financial and

economic crisis plays an important role in recent

developments due to an important decline in the

demand for materials, in particular construction

materials.

Prior to 2007, there were only a handful of instances

of absolute decoupling of material consumption

from economic growth. Since then, a majority ofOECD countries display an absolute decoupling.

As economic growth resumes, the demand for

materials will increase and will exceed pre-crisis

levels unless countries strengthen resource

productivity policies and measures.

The consumption of material resources to support

economic activity remains high. An average person

living in an OECD country consumes about 46 kg

of materials per day (about 60% more than theworld average), including 10 kg of biomass, 17 kg of

construction minerals, 5kg of metals and about 13

kg of fossil fuels.

Productivity gains have been

achieved in recent years, but

material consumption remainshigh and progress is moderate

once indirect flows associated

with trade are considered

As OECD economies become more service-

based, their reliance on imports is increasing

with resource-intensive production often being

displaced to non-OECD economies. Imports makeup almost one-third of material inputs in the OECD

area, compared to one quarter in 1990. They make

up 40% in OECD Europe and in OECD Asia-Pacific;

and less than 15% in OECD Americas.

Finished and semi-finished products weigh

significantly less than the raw materials from

which they are derived. When accounting for all

the raw materials that are required to produce

a good but that are not physically incorporatedinto the traded product, the productivity gains in

countries that are net resource importers are more

modest.



11/16

From waste to resources

The amount of solid waste generated by economic activity is rising in

line with growing consumption of material resources. Many valuable

materials continue to be disposed of as waste and, if not recovered,

are lost to the economy. But efforts to recycle waste are starting topay off, and a generally positive trend can be observed for municipal

waste (representing roughly 10% of total waste).

The amount of municipal waste generated per year is around 660

million tonnes; per capita generation decreased by 5% (to 530

kilograms per person compared to 560 in 2000), but remains high

compared to other countries in the world, and is still higher than

in the early 1990s.

Municipal solid waste is increasingly being diverted from landfillsand kept in the economy through recovery or recycling.

Markets for secondary raw materials are expanding, but have to

cope with volatile commodity prices.

Recycling rates have increased for a large range of important

materials, such as glass, steel, aluminium, paper and plastics,

reaching levels as high as 80% for some of these materials. There

are however many precious or specialty metals that are not

recycled or for which recycling rates remain very low.

Efforts to move from

waste to resources show

first results. Recycling

rates are high for a

number of materials, but

many valuable materials

continue to be disposedof as waste

Urban mines: an

important, undervalued

source of raw materials


Raw materials are usually extracted or produced from natural

resource stocks. Valuable materials can also be gained from the

recovery and recycling of solid waste by diverting materials from the

waste stream before final disposal. They can further be extracted

from final waste disposal sites such as landfills, where solid waste has

accumulated over long periods. Valuable resources are also found in

the built environment, and in products and appliances in use. These

urban mines are an important source of minerals and metals for

industry (e.g. electric and electronic equipment), and a potentially

important domestic source of raw materials in the future.

Estimates quantifying the amount of raw material locked in the

economy indicate that the size of future urban mines could be

significant. Reliable estimates have been made for only a few metals.

For example, the stocks of iron locked in the economy are estimatedbetween 12 and 18 million tonnes or roughly 15-20% of global iron

ore reserves in 2011. These estimates form a picture of the amount of

material that could one day be available for reuse or recycling free of

technical or economic constraints.

Closing the loop of the material cycle:

better policies for greener growth

Resource productivity is essential to future economic growth and

development, and hence to prosperity. In the past ten to fifteen

years, improving resource productivity has become a priority for

governments and businesses alike. Many countries are taking

action and some have set national targets for material productivity.

Sustainable resource use and resource productivity are also high on

the international policy agenda. They have been addressed by the

Heads of State and Government of G8 countries, and are actively

promoted by the OECD, UNEP and the European Commission.

Much more is however needed to effectively decouple the use

of material resources from economic growth so as to reduce the

associated negative environmental impacts and avoid waste of

valuable resources.

This involves scaling-up existing policies, establishing proper

framework conditions, and ensuring that policies are more coherent

and better integrated. Some of the key challenges are linked to the

transboundary dimension and complexity of most supply chains and

the large number of economic actors and government agencies that

need to be involved in such policies.

It requires measures and investments to support technological

change and innovations, and to promote integrated life-cycle-

oriented approaches, such as 3R policies, sustainable materials

management and sustainable manufacturing. Significant potential

exists for efficiency gains and improved resource productivity in

many sectors, including construction, transport, agriculture and

manufacturing.

It also requires efforts in policies that affect trade in raw materialsand in certain types of waste, enhanced international co-operation

and capacity development

Filling knowledge gaps:

better information for better policies

A considerable amount of work has been carried out over the past

ten years to develop the methods to analyse material flows andto develop appropriate indicators to monitor progress. Almost

all OECD countries have developed initiatives in this area. In

Europe, reporting on materials flows has become mandatory. This

is supported by the adoption at UN level of the System of

Environmental-Economic Accounting (SEEA) as an international

statistical standard.

However, missing information and inconsistencies still limit the

tracking of progress with resource productivity in many countries and

at international level.

Important gaps include the following:

Material flows that do not enter the economy as transactions, but

that are relevant from an environmental point of view, including

unused materials such as mining overburden and indirect flows of

raw materials associated with trade.

Material flows of importance to the 3Rs, including flows of recyclable

materials and secondary raw materials, and flows of waste.

Distinguishing between primary and secondary raw materials is

crucial for assessing resource productivity and decoupling trends.

The size and the value of the urban mine: with the exception of

some of the most common industrial metals, there are insufficient

estimates of stocks of material locked in the economy to form a

reliable picture of their potential to contribute to future supply.

Capitalising on the potential of the urban mine will require not only

better knowledge of its size, but also its dynamics, how it evolves

over time and in relation to virgin stocks.

Industry-level and material-specific information that is needed to

indicate opportunities for improved performance and efficiency

gains in production and consumption processes along the supply

chain.

Compatible databases for key materials and substances, including

critical raw materials, environmentally harmful substances and

substances that play a role in global biogeochemical cycles.

Many countries have

taken initiatives to

measure material flows

and resource productivity

but significant gaps

remain

14. OECDSCALING UP FINANCE MECHANISMS FOR BIODIVERSITY14. OECD MATERIAL RESOURCES, PRODUCTIVITY AND THE ENVIRONMENT


15/16

There is also considerable scope for deeper analysis

of particular resources and materials, and their

interactions. Examples include trade related

resource flows and flows of secondary raw materials,

the way they interact with commodity prices and

recycling markets, and how they relate to innovation

and to natural resource stocks.

Future work will also need to further explore the

environmental impacts and the costs of material

resource use throughout the life-cycle of materials,

as well as the economic and environmental

opportunities provided by improved resource

productivity. An important task is to improve

understanding of the trade-offs that need to be

made.

Better information will also help make a strong case

for policies aimed at improving resource productivity

by showing the full benefits of such policies.
