 | The green light signals pressures on the environment or
environmental issues for which recent trends have been positive and are expected to
continue in the future, or for which the recent trends have not been so positive, but are
expected to improve. |
 | The yellow light signals areas of uncertainty or potential
problems. These relates primarily to environmental pressures and environmental issues for
which current understanding is inadequate. |
 | The red light signals pressure or environmental conditions for
which the recent trends have been negative and are expected to continue, or for which the
recent trends have been stable but are expected to worsen in the future. The red
lights need to be urgently addressed by OECD countries. |

Structural effects on the environment are
likely in general to be positive, as comprehensive liberalisation of trade and investment
improves resource efficiency. |
The effects of ageing populations on the
environment are not well understood. |
The physical expansion of urban areas
leads to increasing pressure of the environment. |
The environmental goods and services
market is projected to grow rapidly in the future, although it is currently still small. |
Technology effects of globalisation on
the environment are generally expected to be positive or neutral, but may be negative in
some circumstances. |
Scale effects of economic growth on the
environment, spurred by further globalisation are like to be on balance negative. |
|
Environmental impacts from GDP growth
depend on changes in the structure of the economy, technologies employed, environmental
policies, and local environmental conditions. |
Growing environmental pressures from
consumption include increased use of natural resources, pollution associated with
increased energy and transport use, and waste generation. |
|
The environmental effects of current
consumption patterns remain a peripheral issue in most OECD countries, treated in an
ad-hoc fashion. |
|
|
Consumers in OECD countries are concerned
about environmentally quality, but their concern has often not been translated into
behavioural changes. |
|
|
Potential biotechnology advances in
agriculture have raised social, economic, and political questions related to their
potential health and environmental impacts. |

Although environmentally friendly
agricultural systems still represents a small share of total agricultural production, they
are increasingly used in the OECD countries. |
Although water charges in OECD countries
have been increasing, in most cases the full costs of providing water services are still
not covered by water prices. |
Agricultural intensification has led to a
growing use of energy, water and agrochemicals, increased soil erosion, and reduced
habitat provision in OECD countries. |
Eco-labels and agricultural certification
schemes are increasingly used in OECD countries to inform consumer food choices. |
While aquaculture can help alleviate
stress on capture fisheries from increased demand for fish, it can also have negative
impacts on local ecosystems. |
Agrochemicals run-off is one the main
contributors to groundwater pollution in OECD countries, and is expected to worsen to
2020. |
Most OECD households are connected to
basic sewage treatment systems and more advanced wastewater treatment processes are
increasingly used. |
New technologies have the potential to
help improve fisheries management, but also to increase the rate of unsustainable fish
harvests. |
Subsidies to agriculture in OECD
countries are very large, and the majority are tied to potentially environmentally
damaging production or inputs. |
OECD countries are increasingly managing
their water resources on a river basin or catchment basis. |
The share of wood produced in intensive
plantation is expected to increase in OECD regions to 2020. |
By 2020, over one-quarter of a billion
people worldwide are expected to be living under high water stress. |
Timber is increasingly being harvested
from second growth and planted forests, reducing pressures on natural old growth forests. |
Forest quality and biodiversity habitat
in OECD countries may decrease to 2020 because of more intensive forestry practices. |
The pollution of OECD groundwater
resources - particular from agrochemicals run-off - is expected to worsen to 2020. |
OECD countries have been expanding the
area of natural forest that is protected in national parks or reserves. |
|
Fish catch from capture fisheries is
likely to remain stable, or possible decrease, to 2020 because of poor management of fish
stocks. |
Protected natural areas are growing both
in number and size in OECD countries. |
|
A number of common fish species are
threatened with commercial extinction |
|
|
Tropical deforestation is expected to
continue at alarming rates over the next few decades. |
|
|
Perverse incentives, including subsidies
to some sectors, continue to encourage environmentally damaging activities resulting in
biodiversity loss in OECD countries. |

OECD countries are achieving some
de-coupling of energy from economic growth. |
Economic analyses indicate that the costs
of meeting Kyoto targets for Annex I countries would be low, though adjustments costs may
be significant in some sectors. |
Energy consumption in OECD countries and
worldwide is projected to continue to increase to 2020. |
Changes in land use and forestry are
estimated to be a net CO2 sink for most OECD countries. |
Barriers to the widespread use of more
environmentally friendly transport technologies and good practices exist across OECD
countries. |
Fuel combustion remains the major source
of greenhouse gas emissions and many air pollutants. |
Significant reductions in emissions of SOx,
CO and lead have been achieved in OECD countries. |
Despite progress in reducing air
pollution emissions in OECD countries, serious air quality and related human health
problems persist. |
Most subsidies to energy production
continue to support the more environmentally damaging fuel sources. |
|
|
Emissions of CO2 in OECD
countries are projected to increase by app. 33% from 1995 to 2020. |
|
|
Meeting Kyoto targets will require
reducing greenhouse gas emissions in OECD countries by roughly 20% to 40% in 2020 compared
with Reference Scenario projections. |
|
|
Projected emissions of greenhouse gases
will lead to increases in global mean temperature and a rise in sea levels. |
|
|
The contribution of the transport sectors
to the total CO2 emissions in OECD countries is projected to increase from app.
20% in 1995 to 30% in 2020. |
|
|
Noise levels seriously affecting human
health are still recorded in many OECD countries. |
|
|
Emissions of fine and ultra-fine
particulate matter have been increasing in OECD countries, with significant negative
impacts on human health in urban sites. |
|
|
High emission levels of NOx
and volatile organic compounds remain a concern in OECD countries due to their
contribution to the formation of photochemical smog. |

Household demand for freshwater has
stabilised or declined in a number of OECD countries. |
Household energy demands is likely to
continue to rise in OECD countries to 2020, but there is a large potential for further
energy efficiency gains. |
Household private car use and air travel
will increase to 2020, contributing strongly to growing emissions of greenhouse gases. |
Some OECD governments are using
information instruments in combination with other measures to stimulate environmentally
friendly consumer decisions. |
CO2 and SOx
emissions from the steel industry are expected to increase substantially to 2020, but
introduction of new technologies could offset this increase. |
There is a lack of adequate safety
information about the great majority of chemicals on the market. |
The use of recovered paper in the pulp
and paper industry is increasingly rapidly. |
The steel industry has made progress in
increasing its efficiency of resource and energy use, but still uses large amounts of
energy, water, and iron ore. |

regions is projected to grow by 43% from 1995 to 2020. |
The emission of some pollutants to the
environment from the chemicals industry is descreasing. |
Steel production has negative impacts on
human health, but these effects have been reduced in recent years. |
Soil contamination at existing waste
dumping sites is expected to continue, affecting land use and ground water quality. |
Tremendous progress has been made in OECD
