volume: Conceptual computer artwork of the total volume of water on Earth (left) and of air in the Earth’s atmosphere (right) shown as spheres (blue and pink). The water sphere measures 1390 kilometers across and has a volume of 1.4 billion cubic kilometers. This includes all the water in the oceans, seas, ice caps, lakes and rivers as well as ground water, and that in the atmosphere. The air sphere measures 1999 kilometers across and weighs 5140 trillion tonnes. As the atmosphere extends from Earth it becomes less dense. Half of the air lies within the first 5 kilometres of the atmosphere. Image by Dr Adam Nieman.

Science for policy?
Climate change – IPCC
Biodiversity – Millennium Ecosystem Assessment, now the International Platform on Biodiversity and Ecosystem Services
Hazardous substances – Basel Convention
Ozone – Montreal Protocol’s scientific assessments
And many others…
…but no international assessments to support decision making on resources.
Objectives
Terms of Reference:
To provide independent, coherent and authoritative scientific assessments of policy relevance on the sustainable use of natural resources and in particular their environmental impacts over the full life cycle;
To contribute to a better understanding of how to decouple economic growth from environmental degradation.
In short: To give decision-makers the information they need to respond to resource challenges
Background
Understanding how to decouple environmental impacts and resource use from economic growth…
… while avoiding burden shifting between countries, generations, and trade-offs between impact categories and life cycle stages.
What are we talking about?
Resource use
Economic activity
Environmental impacts
Quality of the environment
Time
Fundamental concepts - DPSIR
Decoupling means breaking the links between (1) economic growth and (2) resource and environmental pressures and impacts and associated impacts
Decoupling responses target the drivers of impacts and resource use, while maintaining economic growth and welfare.
Key issues
Resources are important to many aspects of development: economic growth, poverty reduction, environmental impacts.
We need a better understanding on many issues related to resources: More thought is needed about what this means for
developed, emerging and developing countries. Policy making needs a sophisticated approach that
considers burden-shifting and trade-offs. What are the economic impacts of resource policies? How do trade issues, resource rights and poverty
reduction come into the picture?

The metals challenge
Metals are essential for economic development
Base metals like steel and aluminum, mainly for buildings and infrastructurePrecious and specialty metals, like palladium and indium for modern/clean
technologies
Global demand for metals is increasing
E.g. copper and aluminum have doubled in the past 2 decadesRising demand in emerging economies and developing countriesVery strong demand growth for many precious and specialty ('technology') metals
The increasing global demand for metals causes many problems and challenges
Increasing environmental pressures from extraction and manufacturing of raw materials
Growing dependence on regional or economic concentrations of natural resourcesIncreasing risks of international crisis (e.g. war lord activities in parts of Africa)Social tensions among local populations (land owner issues etc.)
UNEP’s Global Metals Flows Group
Promoting the recycling of metals
and a “circular economy”
Work on a series of six
assessment reports

Metal stocks in society
The metals stocks in society are increasing worldwide
In-use stock of copper has grown in the US from 73 to 238 kg per capita (1932-1999)The world average is 50 kg copper per capita (2000)In-use stock of steel in China is 1.5 tons (2004) per capita, but in the USA it is 11-12
tons per capita (2004)If the whole world would copy the industrialized countries the global in-use metal
stocks would be 3 to 9 times present levelsFor many technology metals, like indium and rhodium, more than 80% extracted
from natural resources was in the past 3 decades
There is a substantial shift in metals stocks from below ground to above ground
These “mines above ground” have growing potential for future metals supply
E.g. average lifetime of copper in buildings is 25 to 40 years, but for metals in cell phones and PCs it less than 5 years
www.unep.fr/scp/rpanel
The relevance of recycling
Enhanced recycling of metals from in-use stocks is a key solution for SD
The production of metals from secondary raw materials reduces environmental impacts compared to primary metals production
High energy savings and reductions of greenhouse gas emissionsSecondary steel causes 75% less GHG emissions compared to primary steelGHG emissions of secondary aluminum production are about 12 times lower than of
primary aluminum productionRecycling reduces the pressure on biodiversity, water resources etc.
Recycling of metals moderates dependencies on natural resources, which are often concentrated in insecure regions
Recycling ensures sustainable access to potentially scarce metals
Recycling creates new jobs and income all over the world
www.unep.fr/scp/rpanel
Recycling rates of metals
Investigation of 62 different metals
The metals are grouped into four categories
9 ferrous metals: iron, manganese, nickel, chromium etc.8 non-ferrous metals: aluminum, copper, lead, zinc, tin, magnesium etc.8 precious metals: gold, silver, platinum, palladium, rhodium etc.37 specialty metals: indium, gallium, lithium, tantalum, rare earth metals, tellurium etc.
The most important metric is the end-of-life recycling rate
A high end-of-life recycling rate for a metal indicates a high efficiency of the related post -consumer recycling system
Only a few metals, like iron and platinum, currently have an end-of-life recycling rate of above 50%
www.unep.fr/scp/rpanel
Ferrous metals: steel example
www.unep.fr/scp/rpanel
Recycling rates of steel
The most widely-used metal – construction, infrastructure, vehicles, etc.
Current global production counts on 1.3 billion tons steel per year, which causes 2.2 billion tons of greenhouse gas emissions (4-5% of total man-made emissions)
Often used in very large pieces (steel beams, auto bodies), which makes recycling more probable
Recycled iron requires only about 25% of the energy needed to produce virgin iron
Estimated 2009 end-of-life recycling rate: >50% (varies among countries and iron-containing products)
An additional substitution of just 100 million tons of primary steel by secondary steel has a GHG reduction potential of about 150 million tons CO2

Non-ferrous metals: copper example

www.unep.fr/scp/rpanel
Recycling rates of copper
Common uses: power distribution, electrical wiring, plumbing
Usually used in pure form and in rather large pieces, which makes recycling more probable (exception: electric and electronic devices)
Increasing demand for infrastructure and innovative technologies , like electric vehicles
Increasing small-scale applications in which copper is embedded in a complex matrix: cell phones, DVD players, electronic toys etc.
Estimated 2009 end-of-life recycling rate: 25-50% (varies among countries and copper-containing products)
Lack of adequate recycling infrastructure for WEEE (Waste Electrical and Electronic Equipment) in most parts of the world causes total losses of copper and other
valuable metals like gold, silver, palladium, tin etc.
www.unep.fr/scp/rpanel
Precious metals: palladium example
www.unep.fr/scp/rpanel
Recycling rates of palladium
Current global mine production about 220 tons/year; high regional concentration
Main applications are automotive catalysts (> 60%) and electronics (> 16%); further applications industrial catalysts, dental, jewellery
Current end-of-life recycling rate 60-70% (global average)
Excellent rates for industrial applications: 80-90%
Moderate rates for automotive applications: 50-55%
Poor rates for electronic applications: 5-10%
Increasing problems due to lack of recycling infrastructure for consumer goods
Less than 10% of post-consumer cell phones are recycled in an appropriate way
The main problems are insufficient collection and pre-treatment schemes in the most countries of the world

Specialty metals: indium example

indiumtellurium
www.unep.fr/scp/rpanel
Recycling rates of indium
Strategic metal used for LCD glass, lead-free solders, semiconductors/LED, photovoltaic etc.
Strong growth in gross demand is predicted for indium: from ca. 1,200 tons (2010) to ca. 2,600 tons (2020)
Specialty metals like indium are crucial for future sustainable technologies like PV, battery technologies, catalysts, efficient lighting systems etc.
The supply of indium from natural resources is crucial: so-called minor metal, which occurs just as a by-product (mainly zinc ores) in low concentrations
The current end-of -life recycling rate of indium is below 1% like for the most other specialty metals: urgent progress is necessary to enhance their recycling
www.unep.fr/scp/rpanel
Critical metals for clean technologies - examples
Tellurium, selenium for high efficiency solar cells
Neodymium and dysprosium for wind turbine magnets
Lanthanum and cobalt for hybrid vehicle batteries
Terbium and indium for advanced metal imaging
Gallium for LED
Platinum for automotive catalysts and fuel cells
These and other critical metals become essentially unavailable for use in modern technology without enhanced end-of-life recycling rates in the future!
www.unep.fr/scp/rpanel
Conclusions
Metal stocks in society are increasing continuously
These “mines above ground” could contribute to decoupling of resource use from economic growth by efficient recycling
UNEP’s work on metals has shown just moderate or even poor end-of-life recycling rates for many metals
Only for a limited number of metals, like iron/steel, palladium and platinum , could rates above 50% be stated
Many metals show rates below 25%, or even below 1% (for many specialty metals)
Serious data gaps on stocks in society and recycling rates have to be closed
Enhanced recycling rates could help to reduce environmental pressures (GHG emissions, water and land consumption, waste, pressure on biodiversity), and it is crucial to secure sustainable supply of critical metals
Improved recycling schemes will give many people new jobs and a living
