2 Children’s Environmental Health Indicators (CEHI)
Summary –
Children’s Environmental Health Indicators (CEHI):
Presenting Regional Successes
Learning for the Future
Children’s environmental health indicators are aimed at improving the assessment
of children’s environmental health, monitoring the effects of interventions to improve
children’s health in relation to the environment and reporting on the state of children’s
environmental health.
The World Health
Organization (WHO)
has been coordinating
the development and
implementation of this
initiative with funding support from
the Office of Children’s Health
Protection at the United States
Environmental Protection Agency
(USEPA), thereby enabling pilot
projects in Africa, North America,
Latin America, the Caribbean and
the Middle East (Box 1). The initiative
builds on existing international,
regional and national work on child
health and environmental indicators.
Several countries have chosen to
collect new data as part of the
implementation of the CEHI initiative
(e.g. Tunisia, Oman and Cameroon).
In addition, several countries are
contributing to the objectives of
the initiative independently through
the development and reporting of
children’s environmental health with
their own sources of funding, while
sharing results and experiences
along the way (e.g. The Commission
for Environmental Cooperation (CEC)
of North America and the WHO
European Region Environment and
Health Information System (ENHIS)
project).
Many countries came forward to be
part of the initial phase to develop
children’s environmental health
indicators. Their experience proved
very benefi cial for other countries
that joined later. It is hoped that even
more countries will engage actively
in future efforts.
The initiative took a fl exible approach
to the implementation of projects,
focusing on what was feasible in the
short-term while working towards
a common set of indicators in the
medium- and long-term where
possible. Each regional or country
project chose the path most suited
to its specifi c circumstances (e.g.
burden of disease, availability of
resources).
The objectives of the
initiative are to:
• Develop and promote use of children’s
environmental health indicators;
• Improve assessment of children’s
environmental health and monitor the
success or failure of interventions;
• Provide data to inform policy-makers
and to allow measurement
of the effectiveness of policies
and programmes to improve
environmental conditions for children.

In order to provide a solid basis for
indicator development and collection,
WHO proposed a set of core indicators
at the global level, which countries
adapted to suit their specifi c needs.
Subsequently, they defi ned and collected
indicators at the national level and integrated them at
the regional level where feasible.
Throughout the CEHI initiative the aim has been to
ensure equal relevance of the indicators for the health
and environment sectors so that both can monitor
their efforts towards realizing healthy environments
for healthy children. The initiative aims to assess best
practices and lessons learned among the different
indicator development projects.

Figure 1. Countries and projects contributing to the development of children’s
environmental health indicators
Indicators provide a basis for
assessing environmental risks
to children’s health, prioritizing
policy, and ultimately reducing
environmental risks for children.
Children’s environmental health
indicators are important not merely
in emphasizing the links between
environment and health, but in drawing
attention to an often neglected
issue. Special attention should be
devoted to children because they
are generally more vulnerable than
adults to environmental hazards.
They breathe more air and consume
more food and water relative to
their size than adults, their bodies
are still developing and they have
little control over their environment.
The findings of the participating
projects clearly demonstrate that
some priority issues are relevant
to children everywhere on this
planet.
An assessment of all these
efforts provides important
information and lessons
on developing and
implementing children’s
environmental health
indicators and will help
guide future efforts.

A Framework for Children’s Environmental Health
Indicators
Children’s environmental
health indicators measure
the multiple links between
exposure to environmental risks
and health outcomes. The Multiple
Exposures Multiple Effects (MEME)
model is a conceptual model for the
defi nition, collection and reporting
of children’s environmental health
indicators on the basis of the
Driving forces – Pressures – State
– Exposure – Effects – Actions
(DPSEEA) framework (Figure 2).
Although several frameworks are
available, embedding indicators for
children’s health and the environment
within the MEME model has several
advantages. It helps to:
o Demonstrate the many links
between environmental exposures,
larger social contexts and health
outcomes;
o Illustrate a spectrum of exposures
and the many locations where
they may occur. These exposures
often work in concert, resulting in
compounded reactions and health
outcomes that may range from
morbidity to mortality;
o Acknowledge that effects of
environmental exposures may be
modifi ed by social, economic and
demographic conditions;
o Show that interventions can
be implemented either in a
preventive manner – at the root of
environmental degradation / at the
site of exposure - or in a remedial
fashion, through the treatment of
negative health outcomes.
Figure 3 shows an adapted example
of the MEME model applied to indoor
air pollution as used in the North
American project led by the CEC
in 2006. As the model suggests,
a number of air contaminants –
individually or in combination – can
produce or be associated with a
number of health outcomes (Briggs,
2003). Conversely, a single health
outcome may be attributable to or
associated with multiple exposures
to multiple substances over time.

Key Findings Across the CEHI Projects
Children’s environmental
health risks worldwide are
as diverse as the climatic
conditions, political settings,
social environments, and levels of
economic development they inhabit.
Risks range from the long-standing
and well-known issues (such as
inadequate shelter, lack of clean
water and clean air) to more recent
emerging risks, such as exposure
to chemicals, radiation, and climate
change.
Key fi ndings confi rm that diarrhoeal
diseases from inadequate water
and sanitation and respiratory
diseases from indoor and outdoor air
pollutants threaten children’s health
in Tunisia, the United States, Mexico
and countries in Europe alike. In
low income countries, pollutants
in the air children breathe indoors
commonly come from black carbon
from the use of biomass fuels, and in
other countries, exposure to second
hand smoke. This broad range of
identifi ed risks is highlighted below.
o Cameroon: Inadequate access
to water, sanitation and waste
disposal were identified as the
major contributing factors to the
environmental burden of disease
in children.
o Kenya and Zimbabwe: Rapid
urbanization was singled out as
the source of several clusters
of environmental health risks
ranging from inadequate
infrastructure to unfavourable
social environments.
o Oman: Respiratory diseases and
physical injuries rank at the top of
environmentally related threats to
children’s health. While expanding
water access almost universally
has dramatically reduced mortality
and morbidity due to diarrhoeal
diseases, improving water quality
still remains a national priority.
o Tunisia: A survey of children’s
environmental health issues
and evaluation of existing
environmental and health policies
led to revised national programmes
to reduce indoor air pollution and
to the incorporation of child safety
provisions in urban planning
projects.
o The European Region: Respiratory
diseases and physical injuries
were found to be priority areas
for action. Major contributing
factors are smoking and obesity.
Radiation and exposure to
hazardous chemicals represent
emerging environmental health
risks.
o North America (Canada, Mexico
and the United States): Indicators
were reported under three thematic
areas: asthma and respiratory
disease, effects of exposure to
lead and other toxic substances,
and waterborne diseases. Only
one of the indicators, addressing
asthma in children, was fully
reported by all three countries.
Although the countries were able
to provide relevant information for
most of the selected indicators,
this clearly illustrates the
challenge of obtaining comparable
information on environmental
health issues across sectors and
national borders. Overall, these
data show a rise in reported cases
of childhood asthma across North
America.
o Argentina: Identification and
collection of information on
children’s diseases such as asthma
and diabetes was not complete
while data on long standing and
well known indicators (e.g. water
pollution indicators and diarrhoeal
diseases or malnutrition) were
complete. Gaps were identifi ed in
data relating to many recent and
emerging environmental threats
(e.g. diseases related to chemical
exposure or climate change).

Comparing Different Experiences in Implementing
CEHI
O ne of the principal aims was to
adopt a fl exible approach to
the selection of indicators and
collection of data. In order to facilitate
this exercise, a two-tiered evaluation
was conducted in collaboration
with the Johns Hopkins School of
Advanced International Studies
(SAIS) in the United States, at the
project level and at the indicator
level by, for example, trained
interviewers, external consultants,
and stakeholders. Eight evaluation
criteria served as the framework for
the comparison and evaluation of
the different projects (Box 2).
Each project was unique and
contributed to the development and
improvement of the objectives of
CEHI. More specifi cally:
o Cameroon served as an example
of how an initial primary data
collection effort can serve as a
guide for future priority setting in
the implementation of national
programmes;
o Kenya developed a well-designed
and highly sophisticated plan for
data collection;
o Zimbabwe demonstrated its ability
to collect valuable secondary
data from a variety of sources
at the sub-national, national and
international level;
o Oman had an ambitious plan for
the collection of an extensive list
of indicators, demonstrating a
desire to comprehensively assess
children’s environmental burden of
disease;
o Tunisia is taking plans further.
Following primary data collection
for CEHI, the plans are to set up
a national monitoring system for
children’s environmental health;
o The European region project
served as an example to others
of a well-established concerted
effort and demonstrated the
possibilities that can arise from
successful collaboration among
different actors and countries;
o The project in North America
successfully respected national
differences while creating a unifi ed
project among the United States,
Mexico and Canada by allowing
flexibility in the data reported
under each indicator;
o The United States-Mexico
border project demonstrated
the importance of focusing on
the local realities of regions and
of portraying those realities in a
graphic, user-friendly manner.
o Argentina established a multi-sectoral
and participative
workgroup and using the MEME
model, produced an indicator
profi le on children’s environmental
health (Perfi l Sana). This provides
a useful tool for decision-making
on children’s environmental health
policies.
The cross-project evaluation found
several commonalities in the
prioritization of health issues. The
most striking one consists of the fact
Box 2. Evaluation Criteria
I. EVALUATION AT PROJECT LEVEL:
1. Prioritization of children’s environmental health topics
2. Data collection method
3. Inter-sectoral collaboration and capacity building
4. Report format.
II. EVALUATION AT INDICATOR LEVEL:
5. Comprehensiveness of indicators
6. Utility and practicability of the indicators
7. Level of disaggregation (e.g. by gender, socioeconomic status, provision of
time-trend)
8. Policy relevance (e.g. is the indicator child-specifi c? or is the indicator rel-evant
for devising policies?).

that three indicator topics – water
and sanitation, indoor/outdoor air
pollution and respiratory illness –
were chosen by almost all efforts
as priorities. Unintentional physical
injuries and exposure to chemical
contaminants are other recurrent
issues across all regions. At the
International Children’s Environmental
Health Indicators (CEHI) workshop
in Hammamet, Tunisia, in 20084, it
was established that the three topics
identifi ed above could serve as the
basis for the development of a set of
core indicators that all participating
members could use and append with
complementary indicators suited
specifi cally to their local needs.

Box 3. The Eastern Mediterranean Region – The Tunisian Experience
The Tunisian pilot project prioritized environmental health issues according to the results of a preliminary survey to
identify focus areas.
The survey has three modules: (i) roster of people and health, (ii) housing quality and water, hygiene, and (iii)
sanitation. This assessment tool did not cover environmental health exclusively, and collected information on a
variety of biological, hygienic and behavioural determinants of human, specifi cally child health.
Primary data populated the 46 indicators selected, all newly collected as part of the CEHI pilot project through the
implementation of household surveys. The Tunisian example demonstrates the value of using external (e.g. WHO’s
list of available indicators5 or the MEME model) and local resources effi ciently, while defi ning national priorities.
The fi nal report presents – in a graphic and user-friendly manner – all of the data collected and provides a detailed
discussion of both the lessons learned and the ways in which Tunisia’s initial activities can be carried forward in the
future.

Box 4. The Americas – The experience of the Council of the North
American Commission for Environmental Cooperation (CEC)
The North American project prioritized environmental health issues according to the recommendations adopted by
the CEC of North America in 2002 in recognition of the shared environmental health threats to children in the three
countries: (i) exposure to lead and toxic substances, (ii) respiratory illnesses, and (iii) waterborne diseases.
Suitable indicators were identifi ed according to data availability, scientifi c soundness and credibility, and indicator
applicability and clarity. Country reports were prepared by each country, providing data and contextual information
to populate the 13 indicators selected, drawing on national and local datasets.
While not all countries presented data for all indicators, missing data were replaced by alternative, yet related
measures. Thus the project acknowledged existing data gaps as well as national differences among the participating
countries.
The fi nal report, based on the country reports6, provides extensive information and illustrations of data sources and
analysis. A discussion of lessons learned regarding both individual indicators and the project as a whole, including
data needs and opportunities for enhanced cooperation, is also included.

Linking Indicators to Existing Mechanisms
Overall, the biggest challenge
is integrating the indicators
into existing surveys and
reporting tools both at national and
international levels.
The process of implementing
CEHI in countries will need the
participation of multilateral agencies
such as WHO, the United Nations
Environment Programme (UNEP),
the United Nations Development
Programme (UNDP), the United
Nations Children Fund (UNICEF),
the Organisation for Economic
Opportunities include:
o I n c o r p o r a t i n g c h i l d re n ’s
environmental health indicators
into existing national data
collection mechanisms such as:
• censuses
• clinical data
• data collected and monitored at
community level in cooperation
with schools
• routinely collected environmental
data
• routinely collected paediatric
data.
o I n c o r p o r a t i n g c h i l d re n ’s
environmental health questions
and issues into international
surveys and data collection and
reporting mechanisms such as:
• Demographic and Health
Surveys (DHS): Implemented
by Macro International Inc. in
75 countries, the DHS collects
nationally representative
population-based surveys with
large sample sizes (usually
between 5000 and 30 000
households).
• GEO Data Portal: This portal
is the authoritative source
for data sets used by UNEP
and its partners in the Global
Environment Outlook (GEO)
report and other integrated
environment assessments. Its
online database holds more
Cooperation and Development
(OECD) and the World Bank as
well as national governments,
nongovernmental organizations and
other stakeholders.
Incorporati ch ren’s

than 450 different variables, as
national, subregional, regional
and global statistics or as
geospatial data sets (maps),
covering themes like freshwater,
population, forests, emissions,
climate, disasters, health and
GDP.
• Living Standards Measurement
Study (LSMS): Implemented
by the World Bank to help
policy makers identify how
policies could be designed and
improved to positively affect
outcomes in health, education,
economic activities, housing
and utilities, etc.
• Joint Monitoring Programme
for Water Supply and Sanitation
(JMP): Implemented by WHO
and UNICEF. The overall aim of
the JMP is to report globally on
the status of the water supply
and sanitation sector, and to
support countries in improving
their monitoring performance
to enable better planning and
management at the country
level.
• Millennium Development Goals
(MDGs): The United Nations
site for the MDG Indicators
presents the official data,
definitions, methodologies
and sources for more than 60
indicators to measure progress
towards the MDGs. The data
and analyses are the product
of the work of the Inter-agency
and Expert Group (IAEG) on
MDG Indicators, coordinated
by the United Nations Statistics
Division.
Box 5. Children’s Environment and Health Action
Plan for Europe (CEHAPE) – Europe’s action
programme
The Fourth Ministerial Conference on Environment and Health (2004) adopted
CEHAPE, an international instrument negotiated with member states to develop
and manage environmental health indicators. The project, established by the
WHO Regional Offi ce for Europe, set four regional priority goals identifying key
themes for action on children’s health in relation to environmental factors:
gastrointestinal health related to safe water and adequate sanitation; healthy
and safe transport, mobility, and home environment to reduce injuries and
enhance physical activity; respiratory health and clean air; and health through
an environment free of hazardous chemical, physical, and biological factors.
The declaration from the Ministerial Conference reaffi rmed that environmental
health indicator systems are essential for policy making relevant to children’s
environmental health. With this in mind, an international project – Implementing
Environment and Health Information System in Europe (ENHIS), co-funded by
the European Commission (EC) and coordinated by the WHO Regional Offi ce
for Europe – developed a prototype of an evidence-based system to support
children’s health and environmental policies in the European Region.
The interdependence between science and policymaking is probably best
exemplifi ed by the interaction between CEHAPE7 and ENHIS8. While indicators
serve as the basis and starting point for CEHAPE, the very same indicators
are also used to benchmark and evaluate the resulting policy actions through
ENHIS.

• Multiple Indicator Cluster
Surveys (MICS): The MICS
programme developed by
UNICEF assists countries in
fi lling data gaps for monitoring
the situation of children and
women through statistically
sound, inter n a t i o n a l l y
comparable estimates of
socioeconomic and health
indicators. The household
survey programme is the largest
source of statistical information
on children.
• World Health Statistics:
Implemented by WHO, the
World Health Statistics contains
WHO’s annual compilation of
data from its 193 Member
States, and includes, in the
2009 report, a summary of
progress towards the health-related
MDGs and targets.
This integration of CEHI into existing
international and national data
collection and reporting mechanisms
could translate into a valuable tool.
Although some of the information
readily collected, reported and
available through international and
national surveys or databases could
be used to monitor and evaluate
children’s environmental health, pilot
studies identifi ed large data gaps in
information across countries and
regions.
Good quality information is available
on indicators related to water quality
for example but gaps exist in
indicators related to pesticides, child
labour, nutrition, and unintentional
injuries.
Box 6. Argentina
On the basis of the preparation of the Indicator Profi le for Argentina and the
assessment of children’s environmental health and other on-going efforts in Argentina,
the development and creation of a Working Group on Children Environmental Health at
the Argentinean Society of Paediatrics and the promotion of Children Environmental
Health Units (Unidades Pediatricas Ambientales), were launched at different levels in
the country with strong involvement of paediatricians. The information and evidence
contained in the Indicator Profi le has helped promote an “Atlas of Children in
Argentina” under the National Ombudsman carried out with support from UNDP, UNICEF,
the International Labour Organization (ILO) and the Pan-American Health Organization
(PAHO).

MOVING FORWARD
In April 2008, a group of international technical experts and representatives of governments and
partner agencies committed to children’s environmental health indicators convened in Hammamet,
Tunisia to assess the progress made with the project and to discuss future directions. On the basis
of discussions about the challenges faced and the lessons learned from the experience of collecting
indicators, participants developed 10 key ideas to ensure the sustainability of the initiative:
ENGAGE IN A TARGETED ADVOCACY AND COMMUNICATION STRATEGY
The need to draw attention to children’s environmental health issues and more specifi cally towards data collection
and reporting, to involve all stakeholders, including children themselves, as well as recognize, replicate and
disseminate successful experiences was identifi ed. There is a need for a few simple key messages – targeted to
specifi c audiences such as policy-makers, public health offi cials, healthcare providers – detailing the importance of
indicator development. Educational practices and methodologies which build knowledge and understanding while
encouraging participation of children can play a role in decreasing the severity of impacts from environmental
health impacts.
INCORPORATE CHILDREN’S ENVIRONMENTAL HEALTH INTO CLIMATE CHANGE ISSUES
In order to increase the visibility, relevance and usefulness of children’s environmental health, it is important to
incorporate the initiative into the climate change agenda. Children are particularly vulnerable, and are likely to
suffer disproportionately from both direct and indirect adverse health effects of climate change. Recent estimates
suggest that almost 90% of the global burden of disease from climate change is borne by children (WHO 2007c).
There is a need to enhance the understanding of current and potential impacts of climate-related risks, of the
degree of population vulnerability, of characteristics of vulnerable groups (such as children), of the type of
surveillance and alert and emergency management systems, of the most useful indicators for monitoring and
evaluation, and of the criteria for action.
HIGHLIGHT ECONOMIC BENEFITS OF ADDRESSING CHILDREN’S ENVIRONMENTAL HEALTH
The economic benefi ts of preventing environment-related diseases are many and must be quantifi ed and clearly
communicated to policy-makers. This work has begun at the OECD and should be continued. Existing data mainly
refl ect health outcomes and remedial actions, but rarely expose the responsible environmental risk factors.
However, knowledge about these risk factors is essential for countries to strengthen preventive programmes
in addition to responsive medical care. This will help to avert diseases, save children’s lives, improve families’
livelihoods and reduce the burden on a nation’s health care system. Children’s environmental health indicators
can be used to identify specifi c cost-effective interventions targeted towards the improvement of children’s
ENSURE GREATER POLICY RELEVANCE OF INDICATORS
Children’s environmental health indicators provide a way to clarify the linkages kage
between the environment
and health. Indicators may refl ect the effectiveness of past and current rrent pol
policies, and may suggest needs and
opportunities for new interventions to improve children’s health. Policy olicy r
relevance is a key consideration in
selecting and designing indicators.
CREATE A CORE SET OF INDICATORS TO FACILITATE COMPARABILITY
The difference in the approaches taken by the pilot projects makes comparisons very diffi cult. It was suggested
that a limited number of indicators (i.e. a core set) applicable to all regions be agreed upon through a collaborative
expert opinion approach. Subsequently, each region could develop complementary indicators specifi c to its own
circumstances, taking into account traditional as well as emerging threats. In this manner, cross-country/regional
comparisons would be facilitated, as would tailor-made assessments of the local burden of disease related to

INTEGRATE CHILDREN’S ENVIRONMENTAL HEALTH INDICATORS INTO NATIONAL HEALTH INFORMATION
SYSTEMS
In order to ensure continuity of this work, children’s environmental health indicators need to be integrated into
other data collecting and reporting mechanisms in a harmonized manner that allows a regional and global
comparability and monitoring. The WHO/Health Metrics Network Framework and standards for country health
information systems is a potentially useful framework for such integration. This would ensure that child health
indicators can be collected sustainably over time, increase their prominence and avoid duplication. It would
be wise to reduce the number of data items to be collected and focus on a few key ones in order to minimize
the burden on other data collection systems and facilitate inter-country comparisons. Incorporating specifi c
questions or even specifi cally developed environmental health components into nationally implemented surveys
(e.g. DHS, MICS, LSMS), constitute potential areas within which children’s environmental health indicators could
be integrated.
DISAGGREGATE DATA AND PROVIDE STATISTICAL INFORMATION
In order to increase the policy relevance of indicators, they should be highly representative and appealing,
and provide a comprehensive overview of the particular situation in a country/region. Moreover, consistent
geographical, gender, and age disaggregation would be useful, as well as the reporting of confi dence intervals
where applicable.
CREATE AN INTERNET PORTAL AS A REFERENCE FOR PARTICIPATING COUNTRIES
Data collection and reporting efforts would be facilitated by the creation of a dedicated web portal hosted by
WHO. Participants could contribute immediately, subject to agreeing technical issues, by uploading their data on
a regular basis and draw on the portal by being able to consult legislation, surveys, best practices, etc. A web
log or a “Q&A” section on such a website would also be useful for national planners to seek guidance and share
experiences, problems, and resources.
STRENGTHEN INCENTIVES TO REPORT
In order to ensure sustainability of the development and use of indicators for children’s environmental health, it
is recommended to strengthen harmonized reporting requirements, thus reducing the reporting burden.
CONTINUE TO PROVIDE TECHNICAL ASSISTANCE THROUGH THE CEHI NETWORK
One common request was the provision of technical assistance to countries and regions that wish to develop
indicators. Although sustainability is key and data collection tools/mechanisms must be rendered self-sustaining,
continuous technical assistance – particularly in the early phases of indicator development – is
crucial. Countries have requested ongoing technical input and support. More assistance could be provided
to countries for data collection and reporting, presenting, analysing and disseminating data through the
establishment of an international CEHI technical network involving stakeholders at every level (e.g. national,
regional and international). Funding remains an issue for several projects and regions and hinders scale-up
efforts.
These 10 key ideas provide a sense of
how far the CEHI initiative has come
and how much potential it has to grow.
The ideas highlight the need for greater
coordination and harmonization, but at
the same time call for specific, tailor-made
approaches to the collection of data
on children’s environmental health and
fi nancial support.
Translating evidence into policy
Producing a list of relevant indicators and
populating them with data is a necessary
step towards the ultimate goal of improving
children’s health. However, future actions
must strive to close the gap between
theory and practice.
The CEHI initiative explicitly addresses
the need to improve knowledge and
data collection, and invites participation
from private and public partners. Policy

interventions in the area of children’s
environmental health can range from
school education to waste collection
improvement, emission controls and
improved stoves, food regulation and
fl ood control, housing improvements and
disease eradication programmes. Without
a thorough understanding of the linkages
between multiple exposures and multiple
effects, it is not possible to determine
the costs, benefi ts, and effectiveness of
potential interventions (Box 5 & 6).

Conclusion
Establishing and using children’s environmental health indicators that express environment and health linkages
in a meaningful way provides countries with the foundation needed to better understand how children’s
environments and their health are related. In addition it provides the baseline information needed to reassess
policies and to move towards preventing childhood death and disease through healthy environments.
What is now required includes:
o the creation of a sustainable clearing house for children’s environmental health indicators;
o the institutionalization of the harmonized collection and reporting efforts undertaken in the framework of the pilot
projects; and
o the effective translation of the vast and comprehensive fi ndings into policy recommendations tailored to specifi c
target populations and areas.
This involves the development of models and application of other statistical tools to enable linkages within complex
systems to be understood. The CEHI initiative offers for the fi rst time a systematic approach to supply the data
necessary for such a task.

This brochure summarizes the process, outcomes and key fi ndings of the children’s environmental
health indicator projects implemented as part of the global initiative on Children’s Environmental Health
Indicators. Discussions took place at the Children’s Environmental Health Indicators (CEHI) workshop
“Children’s Environmental Health Indicators: Five Years After the Global Commitment at the World Summit
on Sustainable Development” in Tunisia in 2008. The participants of this workshop included technical
experts, representatives from governments, public health offi cers, medical doctors and representatives of
partner agencies. Challenges faced and the lessons learned from the experience of collecting indicators
were discussed; 10 key ideas to move forward were agreed upon.
The global initiative on Children’s Environmental Health Indicators was launched at the World Summit on
Sustainable Development in 2002 with partners from fi ve governments, three nongovernmental organizations
and fi ve intergovernmental organizations with support from the Offi ce of Children’s Health Protection at the
United States Environmental Protection Agency.
