Issues
• What have we achieved so far?
• Do we understand sustainable development?
• Issues that we have to tackle
Environmental Policy and Sustainable
Development in Hong Kong
• Improvements in environmental quality while
maintaining economic growth
• Problems remain
• Waste disposal is a critical problem
• Transition from an exclusively local focus to a
regional PRDR focus (air and water)
• Implication is that problems cannot be dealt with
by purely local policy and action

1999 Policy Address
Sustainable Development Unit (2001) and
Council for Sustainable Development
(2003)
• Hong Kong 2030 is “adhering to the principle of
sustainable development”
• This “requires that we balance social, economic
and environmental needs so that a vibrant
economy, social progress and better environmental
quality can be achieved simultaneously. In this
connection, we will inter alia, apply the evaluation
tool, i.e., the CASET, developed in the SUSDEV21
Study in the strategy formulation process in order
to obtain as far as possible an optimum balance
between the three factors for the recommended
strategies.”
• Council for Sustainable Development Strategy
Sub-committee
• Vision Statement:
“Our vision is for Hong Kong to be a healthy,
economically vibrant and just society that
respects the natural environment and values its
cultural heritage. By engaging the community in
the process of building a strategy for sustainable
development, we aim to ensure that Hong Kong will
be a city for all to share and enjoy, for this and
future generations”
• Results of stakeholder survey
• Self-completion
questionnaire
with
15
representatives of 8 different stakeholder groups
– 120 responses
• Academics, business, environmental NGOs, other
NGOs, civil servants, Legco/DC members, media,
and environmental professionals
• Selected for their
opinion leaders
knowledge/involvement
as
Debate on Sustainable Development
• Sustainable development
not seen as policy priority
• Level of understanding low
except among
environmental NGOs and
international business
community
• Local business community
lags behind
• Lack of SD strategy, lack
of policy integration and
changing agendas are
problems
• Economic growth and
environment still counterpositioned in Hong Kong
• Debate on SD in HK is not
well-informed
• Progress towards a more
sustainable HK –
government is far more
optimistic than other
stakeholders
• Academics and
environmental NGOs least
optimistic
