UNEP Year Book 2009 Makes the Green Economy Case
UNEP Year Book 2009 Makes the Green Economy Case
25th
Session of UNEP’s Governing Council/Global Ministerial
Environment
Forum 16-20 February
Nairobi, 16 February
2009--The importance of realizing a Global Green New
Deal and the urgent need for a transition to a low
carbon and resource
efficient Green Economy are
spotlighted in the UNEP Year Book 2009,
launched today
at an international gathering of environment ministers.
The Year Book, compiled at the request of the UNEP
Governing Council,
presents the hard facts and worrying
trends while also underlining some of
the
transformational and innovative ideas already being piloted
in both
the developed and developing world.
Achim
Steiner, UN Under-Secretary General and UNEP Executive
Director,
said:” The Year Book serves as a reminder to
the international community
as to why a Green Economy is
so urgently needed from the bubbling up of
methane gas
in the Arctic to the shrinking availability of croplands”.
“But it is also about optimism and the power of
positive policies: from
the way a building in Africa
passively cools itself by mimicking termite
mounds to
the way some countries and cities are pioneering industrial
symbiosis—co-locating businesses and factories to
recycle and re-use
wastes as raw material inputs, saving
finite natural resources, millions
of dollars and the
planet too,” he added.
Highlights
Waste
Over
two billion tones of waste are being generated throughout
the world
annually with someone in a developed economy
throwing away around 1.4 kg
of solid waste refuse daily.
This is however leveling off perhaps as a result of
waste minimization and
recycling measures.
Developing nations, in particular rapidly developing
economies are
producing more waste with China expected
to produce 500 million tones of
solid waste a year, and
India about 250 million tonnes by 2030 based on
current
trends.
Construction and Buildings
There are some
positive developments in particular in the building and
construction sector, not least in energy efficiency
improvements aimed at
cutting the estimated 30 to 40 per
cent of global greenhouse gas emissions
linked with the
built environment.
A world-wide survey conducted by
McGraw-Hill Construction Analytics found
that one third
of industry professionals believe more than 10 per cent of
domestic construction is already moving to higher
resource efficiency.
A further 50 plus per cent said
principles of resource efficiency will be
applied to 60
per cent of their projects in the next five years.
Canada, France and the United Kingdom are among several
countries that
have launched programmes to make
buildings energy neutral—the buildings
generate via
technologies such as solar and combined heat and power
systems as much energy as they consume
The United
Kingdom for example has launched a voluntary industry
agreement
aimed at cutting by half (12.5 million tones)
in 2012 the amount of
construction waste going to
landfill. It could recover materials worth an
estimated
$1 billion.
The Year Book highlights how copying
nature—so called biomimicry—can offer
intriguing
solutions. The Eastgate building in Harare, Zimbabwe has
passive, self-cooling systems modeled on termite mounds.
The building, a mixture of offices, shops and car
parking, uses an average
of 90 per cent less energy than
a comparable structure saving more than
$3.5 million
since opening in the 1990s.
‘Materials substitution’
is another emerging field with researchers around
the
world in a race to produce cement and concrete that can be
made at
temperatures lower than the current 1,000
degrees C.
The Massachusetts Institute of Technology are
currently looking at using
magnesium compounds—a waste
material of many other industrial processes—as
a
substitute for conventional concrete’s
calcium-silicate-hydrate
particles.
Others are
looking at using substitutes based on silicon and aluminum
harvested from waste by-products such as coal ash and
iron slag. They have
the potential to cut C02 emissions
from cement industry by an estimated 20
per cent, while
utilizing an industrial waste and producing a final
product less prone to weathering—the kind of multiple
economic and
environmental benefits at the heart of the
Green Economy initiative.
Dematerialization is another
term in the emerging area of industrial
ecology. At its
simplest it can be captured in consumers demanding less
packaging for example on products. A producer of
unbleached cotton, who
uses fewer resources, might also
be able to charge a higher price and
certainly achieve
higher profit margins.
Industrial symbiosis, or what is
known in China as the Circular Economy,
is an off-shoot
of this concept. The idea is to co-locate businesses and
facilities in such a way that their wastes are raw
materials for other
nearby ones.
Pioneering
Industrial Symbiosis Network in Kalundborg Denmark, now has
more than 25 industrial waste management processes
integrated in one
system.
The United Kingdom’s
Industrial Symbiosis Programme involves more than
8,000
participant companies.
It has diverted more than four
million tones of business waste from
landfills.
Eliminated over 350,000 tonnes of hazardous waste from the environment.
Saved over nine million tones of water,
avoided the use of 6.3 million
tones of virgin raw
materials and reduced carbon emissions by over 4.5
million tonnes.
Generated $208 million in new sales
for members and saved them nearly $170
million.
Chicago in the United States and Shanghai in China have
adopted similar
symbiosis projects.
China’s
Circular Economy initiative is also looking at labeling
products
for their resource consumption backed up by
tough penalties for companies
who use processes,
materials and techniques on a so called ‘eliminated’
list.
If items on the eliminated list are used, the
government can confiscate
the equipment, materials or
product; impose fines of up to $30,000 or shut
the
enterprise down.
Imported items on the ‘eliminated’
list must be returned and a fine of up
to $150,000 can
be imposed under the plan.
If the importer cannot be
identified, then the carrier can be made
responsible for
returning the items or paying for their disposal.
Banks
or other financial institutions are also banned from
supporting
enterprises that manufacture, import or
distribute items on the
‘eliminated’ list.
Transport
Transport accounts for over 20 per cent of
global greenhouse gas
emissions. In 2005 there were an
estimated 650 million vehicles on the
road with that
number expected to double by 2030.
The Indian city of
Chennai is working with the Sustainable Mobility and
Accessibility Research and Transformation initiative
(SMART) at the
University of Michigan in the United
States in order to tackle the twin
economic and
environmental challenges of congestion and pollution.
Railway and bus systems are to be kitted with wireless
technology so that
thousands of computer and software
industry commuters can work en route.
At the stop closest
to work, the commuters can choose from privately-run,
low-polluting shuttle buses; taxis; rental cycles or
walking paths.
The system uses the commuters’ mobile
phones to forecast anticipated
transport and traffic
conditions and needs. Eventually commuters will be
able
to use their phones to check up on the transport networks
and choose
the most efficient mode based on prevailing
conditions.
Industrial Water
Currently close to 880
million people lack adequate access to clean water
and
2.5 billion are without improved sanitation in their homes.
By 2030,
close to four billion people could be living in
areas suffering severe
water stress mostly in South Asia
and China.
Industry uses 10 per cent of water in low and
middle-income countries and
up to close to 60 per cent
in high-income ones.
A Finnish paper mill has switched
from chemical to thermo-mechanically
treated pulp and
installed a biological wastewater treatment
facility—water savings of 90 per cent have been
achieved.
An Indian textile manufacturer has switched
from using aluminum to zinc in
synthetic fabrics—water
consumption has been cut by 80 per cent with the
cleaner
waste water produced suitable for irrigation uses on nearby
farms.
By separating process water from sewage water, a
Mexican sugar cane
company has cut water use by 90 per
cent.
A Spanish company, managing 300km of highways in
Sao Paulo state, Brazil
has designed the roads to funnel
rainwater into 250 containment dams with
a capacity of 2
million cubic metres. The system allows the rainwater to
seep slowly into the ground, assisting in replenishing
the Guarani aquifer
while saving money in terms of
reduced road maintenance.
While some progress is being
made, the Year Book underlines the scale of
the
challenge facing the world towards the end of the first
decade of the
21st century.
Climate Change
2008
had the second smallest area of Arctic sea-ice left
following the
summer thaw since satellite monitoring
began in 1979. The National Snow
and Ice Center in the
United States found that the minimum sea-ice cover,
which occurred on 12 September, was somewhere over 4.52
million square
kilometers.
“While 2008 saw 10 per
cent more ice cover than in 2007, the lowest figure
on
record, it was still more than 30 per cent below the average
for the
past three decades. Taken together, the two
summers have no parallel,”
says the Year Book.
For
the second year in a row, there was an ice-free channel in
the
Northwest Passage through the islands of northern
Canada.
2008 also witnessed the opening of the Northern
Sea Route along the Arctic
Siberian coast—the two
passages have probably not been open simultaneously
since before the last ice age some 100,000 years ago.
The Greenland ice sheet, which could raise sea levels by
six metres if it
melted away, is currently losing more
than 100 cubic km a year—faster than
can be explained
by natural melting.
Losses from the West Antarctic ice
sheet have increased by 60 per cent
between 1996 and
2006.
Losses from the Antarctic Peninsula increased by
140 per cent.
In 2007, the Intergovernmental Panel on
Climate Change (IPCC) estimated
that sea levels might
rise by between 18cm and 59cm in the coming century.
But
many researchers now believe the rise even higher in part as
a result
of new assessments of ice sheets in Greenland
and Antarctica.
One study estimates a sea level rise of
between 0.8 and 1.5 metres, while
another suggests a sea
level rise of two metres in the coming century from
outflows of ice from Greenland alone.
A one metre
rise in sea levels world-wide would displace millions of
people. Around 100 million people in Asia, mostly
Bangladesh, eastern
China and Vietnam; 14 million in
Europe and eight million each in Africa
and South
America.
The Year Book argues that urgent action is
needed to curb greenhouse gas
emissions, not least
because some of the natural carbon storage systems or
‘sinks’ may be losing their absorption capacity
raising the spectre of a
runaway greenhouse effect.
Studies in 2008 indicates that one key ‘sink’—the
oceans—are now soaking
up 10 million tones less C02.
The Year Book also flags up increasing concern among
scientists about
releases of greenhouse gases such as
methane from the Arctic as ice melts
and permafrost
thaws in part as a result of new studies indicating that
the western Arctic is warming 3.5 times more than the
rest of the globe.
This concern has taken on even
greater importance as a result of two
recently published
studies.
A study focusing on North America suggests that
upwards of 60 per cent
more carbon could be stored in
the permafrost than previously supposed.
An international
study has now doubled the amount of soil-carbon in the
permafrost across the entire Arctic.
Marine
researchers have discovered more than 250 plumes of methane
bubbling up along the edge of the Continental shelf
northwest of Svalbard.
The International Siberian Shelf
Study has found higher concentrations of
methane
offshore from the Lena River delta.
Researchers calculate
that, once underway, thawing of the east Siberian
permafrost—thought to contain 500 billion tones of
carbon—would be
irreversible and that over a century
250 billion tones could be released.
Monitoring of
methane levels in the atmosphere indicate that
concentrations rose in 2007 and 2008 after nearly a
decade of stability.
Intriguingly higher concentrations
were detected in both the northern and
southern
hemispheres.
Meanwhile, the Year Book raises concerns
over another carbon sink—forests.
Rising temperatures
may be stressing trees leading to photosynthesis and
thus carbon sequestration halting sooner in summer
months. Stressed
forests may also be more vulnerable to
pollution, disease and pests, again
undermining their
carbon storage potential.
The Year Book also focuses on new research from the Amazon.
A doubling of C02 could
warm the oceans to such a point that rainfall in
the
Amazon could decline by 40 per cent.
Overall an
estimated 53 per cent decline in vegetation growth could
occur.
Forest loss on this scale could in turn raise
temperature ‘locally’ by up
to eight degrees C
triggering further droughts and putting pressure on the
Amazon River, the world’s largest river that carries
one fifth of the
world’s river water.
The melting
of the world’s icy regions, including mountain glaciers is
also triggering other hazards above and beyond the very
serious threats to
water supplies if glaciers melt away:
nearly a billion people in South
Asia rely on seasonal
melt waters from the Himalaya-HinduKush mountain
system
for example.
Hazardous substances, deposited from the
atmosphere and locked away in
glaciers, are now being
re-released.
The pesticide DDT is turning up in
unanticipated amounts in Adelie
penguins that live in
parts of the Antarctic coastline.
Organic pollutants are
being carried back into the environment from
melting
glaciers in the Rocky Mountains of North America.
Polychlorinated biphenyls (PCBs) can be found downstream
of European
glaciers.
Disasters and Conflicts
The
Year Book also discusses the links between natural
disasters,
environmental degradation, conflicts and
human or social vulnerability as
well as the importance
of disaster preparedness—issues becoming of
increasing
concern in a climate-constrained world.
While geological
disasters such as earthquakes and volcanoes have remained
fairly constant over the past century,
hydro-meteorological disasters such
as storms, floods
and droughts have increased dramatically since 1950.
The
frequency of these events has increased by an average of 8.4
per cent
a year between 2000 and 2007.
Another new
assessment says that the total number of disasters has
increased from about 100 events per decade in the period
1900-1940 to
almost 3,000 per decade by the 1990s.
A
further study puts the total number of disasters between
2000 and 2005
at 4,850 and links this to both
‘technological disasters’ such as train
wrecks and
building failures as well as weather events.
The Year
Book spotlights Cyclone Nargis that struck Myanmar with a
peak
wind speed intensities of 215km per hour on 2 May
2008 leaving more than
140,000 people dead or missing
and 2.4 million people homeless and
‘catastrophically
affected’.
As with the 2004 Indian Ocean tsunami, the
loss of ‘environmental
infrastructure’ made coastal
communities more vulnerable.
In the early 20th century,
mangrove forests covered an estimated more than
242,000
hectares in the Irrawaddy River Basin, but by the end of the
century just over 48,500 hectares remained with the loss
linked to
clearance for charcoal and latterly for
agriculture and shrimp farms.
Ecosystems
The 2005
Millennium Ecosystem Assessment concluded that 60 per cent
of the
Earth’s ecosystems—from forests and soils to
coral reefs and
grasslands—are damaged or being
degraded.
The Year Book underlines that this trend is continuing through 2008.
Increasing demand for food and
agricultural production is, under current
systems and
economic models, triggering a dramatic increase in land
under
the hoe and the plough.
Today farmland covers nearly a quarter of the planet’s surface.
Entire forest
systems have effectively disappeared in at least 25
countries and have declined by 90 per cent in another 29
countries.
Marine fisheries are in a state of stagnation
and have been that way for
nearly a decade.
Since the
onset of industrial fisheries in the 1960s, the total
biomass of
large, commercially-targeted marine fish
species has declined by a
‘staggering’ 90 per cent
says the Year Book.
Annual economic losses as a result of
over-exploitation and near depletion
of the most
valuable fish stocks are estimated in 2008 at $50 billion.
Biofuels and their impacts on food production, poverty
and ecosystems can
trigger polarized views with
opportunities for income diversification and
a way of
reducing pressures on cropland possible in small-scale rural
models.
At industrial scales, different crops can
have different impacts. A new
study has assessed the
impact on water use in 2030 based on growing
industrial-scale energy crops under current trends.
An estimated 50 billion litres of maize-based biofuel
produced in North
America would require 20 per cent of
the region’s irrigated water supplies
Producing just
under 34 billion litres of sugar-cane derived biofuel in
Brazil would require eight per cent of irrigated water
supplies.
Rapeseed-derived biofuel made in the European
Union has perhaps the lowest
potential water footprint.
Producing just over 20 billion litres of fuel
would
require just one per cent of the EU’s irrigated water.
The Year Book points out that it is the poor, and
especially the rural
poor who depend on healthy and
functioning ecosystems.
An estimated 90 per cent of rural
poor depend on forests for at least a
portion of their
income.
In rural Africa, small-scale agriculture is the
principal source of income
for some 90 per cent of
people.
Nature-based income accounts for more than half
of the total income stream
for the world’s rural poor.
Better and more intelligent management of ecosystems and
their goods and
services will become increasingly
critical as the century unfolds and the
population
climbs to over nine billion by 2050.
On current
projections the availability of cropland per person is set
to
drop to 0.1 hectares requiring a rise in agricultural
production
“unattainable through conventional
means”.
Soil degradation, linked with intensification,
has now and already
affected all but 16 per cent of the
world’s croplands—healthy croplands
are now confined
to temperate areas of the midwestern United States,
central western Canada, Russia, central Argentina,
Uruguay, southern
Brazil, northern India and northeast
China with a scattering across the
Tropics.
One
possibility is to manage land and landscapes as
‘mosaics’ in which
food production is one of several
central ecosystem services.
So called eco-management as
it is now being termed can date back in some
cases
millennia from the grasslands of Europe to the indigenous
peoples of
the Americas who managed woodlands to create
meadows for deer grazing.
The Terra Preta soils of
central Amazonia have three times more soil
organic
matter, nitrogen and phosphorous and 70 per cent more
charcoal
when compared with adjacent soils—the soils
were generated by
pre-Columbian native populations by
adding “charred residues, organic
wastes, excrement
and bones” to the soils.
Market mechanisms and
financial instruments have a role to play including
payment for ecosystem services.
Clearing of forests
continues at some 13 million hectares annually, equal
to
an area half the size of the United Kingdom. Tropical forest
loss
accounts for an estimated 17 per cent of greenhouse
gas emissions.
Countries are currently assessing the
inclusion of funding for forests in
the UN climate
change arrangements to be agreed in Copenhagen later this
year under the term Reduced Emissions from Deforestation
and Forest
Degradation.
Granting fishing communities
and fishers rights and responsibilities in a
fishery may
also be a way forward.
Surveys of various rights-based
catch shares for example in Canada, Chile,
New Zealand,
Mexico and the United States, indicates that they reduce the
risk of fishery ecosystem collapse while boosting
livelihoods.
Harmful Substances and Hazardous Waste
2008 has been a year of food and product-contamination crises.
In March Italy was rocked by incidents involving
dioxin-contaminated
mozzarella cheese. Dioxins,
substances linked with cancer, are by-products
from a
range of industrial processes including combustion.
The
cases, centering on the region of Calabria, were tracked by
authorities to suspected contamination of pastureland.
In September, China was involved in incidents where milk
including baby
formulas was found to be contaminated
with the toxic chemical melamine.
In Japan in October two
major companies recalled noodle products after
discovering insecticide contamination.
Days later the
country’s largest meat processor recalled products after
discovering that underground water used at a plant near
Tokyo contained
levels of cyanide compounds.
Meanwhile in December in Ireland, the authorities
recalled pork products
again after dioxin contamination
via tainted feed.
Over the past two decades, arsenic
contamination has been detected in a
growing number of
countries in South Asia, says the Year Book.
About 30 per
cent of private wells in Bangladesh show high levels of
arsenic, at over 0.5 milligrams per liter, and more than
half of the
country’s administrative units are
affected by contaminated drinking
water.
The Year
Book indicates that deforestation is aggravating the
situation in
the Amazon. Here forest soils naturally
contain up to three times more
mercury than pastureland
with deforestation releasing mercury to the air
and to
rivers.
