Six central contentions of this lecture:

Delivering sustainable development
Six central contentions:
1. Sustainable development needs an immense
contribution from engineers and engineering.
2. It needs engineers to work with the many
others involved – to do that well, and with an
open mind.
3. The best engineering and construction is,
perhaps, already – or almost – good enough.
© Crane Environmental
Delivering sustainable development
4. But we need to make sustainable development
normal.
5. Engineers generally must take a lead and play
their full part.
6. Fuzziness’ in the definitions of sustainable
development is no excuse for doing nothing.
Practical action is possible now – and needed –
by everyone involved in development.

Coverage of lecture:
© Crane Environmental
Delivering sustainable development
• UK Government’s 1999 Sustainable
Development Strategy both reflects and leads
public opinion, attitudes and actions
• Called A better quality of life, it defines SD as:
 social progress which meets the needs of everyone
 effective protection of the environment
 prudent use of natural resources
 maintenance of high and stable levels of economic
growth and employment
• Sustainable Construction Strategy 2000 –
Building a better quality of life, now being
updated by DTi – Workshop yesterday
© Crane Environmental
Delivering sustainable development
• Forum for the Future definition
• “Sustainable development is a process, which
enables all people to realise their potential and
improve their quality of life in ways that
simultaneously protect and enhance the Earth’s
life support systems.”
© Crane Environmental
Delivering sustainable development
• Thus a distinction needs to be made between a
sustainable society or ‘sustainable living’ as the
goal and ‘sustainable development’ as the
process that will get us there
• However, let us also accept that
sustainable development is also used as a term
about built development - in the UK,
‘sustainable construction’ is being used

• UK Strategy says that delivery of sustainable
development must be across all sectors of
society
• and DTI is pushing industry sectors to
produce their own strategies
© Crane Environmental
Delivering sustainable development
• We can sub-divide SD delivery many ways, eg:
sustainable construction
sustainable manufacturing industry
sustainable farming
sustainable forestry
sustainable transport and tourism
all of which become elements of
sustainable living
© Crane Environmental
Delivering sustainable development
• So, in short:
• Sustainable Development is development
that enables Sustainable Living
• Delivering sustainable development will enable
us all to live more and more sustainably

Two important provisos:
1. Lecture complementary to Special Issue of
ICE’s Journal Civil Engineering, Nov. 2000:
‘Sustainable development: Making it happen’
2. Not discussing climate change, nor other
major related political issues such as the call
for population control – just two of many
drivers for sustainable development
© Crane Environmental
Delivering sustainable development
• The two most-commonly-asked questions:
 What should I do differently?

Can we recognise a sustainable
development when we see one?
© Crane Environmental
Delivering sustainable development
• So, what is it that makes for ‘sustainable
development? Is it:
Where it is: land use, ecological impact?
What it is or is for: materials choice and use,
aesthetics, function?
How it was built: construction impacts?
How it performs: ‘joy in use’, energy and
water efficiency, maintainability, durability,
flexibility, financial success?
All four at once?
© Crane Environmental
Delivering sustainable development
• Civil engineering and sustainable development

Delivering sustainable development
• Civil engineering and sustainable development
A water supply project: a balance between
use of natural resources and social and
economic benefits brought to people
But: concern on particular projects about
– disruption to natural processes
– scale of the infrastructure + demand-led
– adverse impact on some for the benefit of
others
Need for the ‘right’ balance
© Crane Environmental
Delivering sustainable development
• The ‘right’ balance has not always been
achieved in the past:
• We have mastered ‘the art of directing the
great sources of nature for the use and
convenience of man…’
BUT
• We have done it – and may still do it – in
disharmony with the environment and
with some of our fellow citizens
© Crane Environmental
Delivering sustainable development
• How well did we do in the past?
© Crane Environmental
Delivering sustainable development
• Transport infrastructure:
Marc Brunel’s Thames Tunnel lasted well
over a century before major refurbishment
was needed
Isombard Kingdom Brunel’s Great Western
Railway from London to Bristol (completed
in 1841) still in use today
© Crane Environmental
Delivering sustainable development
• These examples pass the high quality design
test, for example in durability and flexibility …
• … and railways are now considered a ‘green’
form of transport
• Yet they are rarely economically successful over
the long term, and
• 19th Century Railway bills subjected to strong
opposition at all stages of their promotion

Delivering sustainable development
• Use of materials:
Timber viaducts became uneconomic when
Baltic timbers were no longer available
No record of Brunel or GWR planting new
trees to re-grow stock used for their bridges
• I K Brunel’s management style …
© Crane Environmental
Delivering sustainable development
• So, is the GWR an example of sustainable civil
engineering or not?
• You be the judge!
© Crane Environmental
Delivering sustainable development
• In summary so far:
 Many engineers have for many years been
trying to take into account the issues in
the sustainable development concept`
 But we – and our clients – have taken
insufficient account of the impact of
construction and operations on the
environment and society
 We have paid too little attention to
resource efficiency.
© Crane Environmental
Delivering sustainable development
• However …
 We have recently learnt a great deal
about how to avoid inadequacies of
much of past practice.
 We now know what actions to take to
deliver a less-unsustainable future and, at
best, a sustainable future
 Sustainable development needs an
immense contribution from engineers
and engineering.

• Will show later that delivering sustainable
development is possible
• First - Issues and challenges to resolve:
© Crane Environmental
Delivering sustainable development
Issues and challenges to resolve:
• SD challenge is very large – but we can tackle it
• It involves new ways of thinking about
development, eg:
 The idea that projects need to be in
better harmony with more sectors of
society, not just with select groups
 The need for a whole-life approach –
whole-life costing and whole-life
environmental assessment
© Crane Environmental
Delivering sustainable development
Issues and challenges to resolve:
• Recognition – Often in the detail
• The resource efficiency challenge
 A great need
 ‘Factor 10’
 A few are demonstrating dramatic changes
• Social acceptability
 Disconnection between individuals’ action and
environmental impact – so they ask: ‘Why do I have
to change?’
 Dealing with conflicting single-issue groups
 Who decides on the greater good
 Who decides who decides
© Crane Environmental
Delivering sustainable development
Issues and challenges to resolve:
• Assessment of impacts
How far afield do we look for impacts, both
positive and negative?
Local – Regional – State – World?
• Timescales
How far into the future do we assess? (We’re
bad at futurology!)
Do one’s best on basis of current knowledge
– eg: long life, loose fit, low energy
© Crane Environmental
Delivering sustainable development
Issues and challenges to resolve:
• The perception that sustainable development is
only for the rich
It’s not! – a myth that it always costs extra
Sustainable development is crucial to
alleviating poverty eg good low-cost housing
• Valuing ‘the environment’
Competing views
Payment vs compensation
• Human values and the environment – We make
value judgements about ‘good’ and ‘bad’

• Projects and Initiatives to help move us
forward:

• Maidenhead Flood Relief Scheme
Design to very high environmental standards
– first Edmund Hambly Memorial ICE prize
Will appear to be a natural river
Costing £98M, yet cost-effective
Now sustaining life in Maidenhead by
significantly reducing the risk of flooding
Yet it should not have been necessary if a
different approach to flood plain
development had been adopted

• Sustainable development characterised by:
Design principles known to only a few
‘manufacturers’
Test-manufactured and test-marketed, for
example in a few housing developments
Yet elements of the concept are practised
more widely than the overall concept

• If sustainable development were a product
• If we were the marketing department of its
owners …
• How would we move Sustainable Development
from …
its small, niche market to …
being as ubiquitous as Coca Cola is as a
‘drink’?
© Crane Environmental
Delivering sustainable development
We would:
• Identify the next most-likely set of buyers
Clients, developers and project leaders, who
can take a long-term view
• Identify the benefits
easier planning approval
cheaper initial construction
much lower operating costs
social acceptability
easier dis-assembly
© Crane Environmental
Delivering sustainable development
We would:
• Study
 why our next target market group buy,
 how they buy,
 how they make buying decisions,
 what advertising messages they respond to
• Identify and deliver our production and delivery
methods, and marketing messages
 actively present the business case
 prepare and disseminate case-studies etc
 use the media, for example at and before
Johannesburg 2002

Delivering sustainable development
We would:
• Move on to consider the same questions for
the next target group
• We can – and must – do this for sustainable
development
Marketing Sustainable Development:
• We – all professionals involved in development
– must do this
• We – you and I – can become the marketing
department and the sales force for sustainable
development
© Crane Environmental
Delivering sustainable development
How?
• We – you and I – can become the marketing
department and the sales force for sustainable
development
• We can demonstrate the concept as far as we
can in our work and personal lives
• We can target the opinion formers we know –
our clients, our governments, our friends – to
do likewise

Practical actions needed
© Crane Environmental
Delivering sustainable development
• The ICE’s Sector Strategy Working Party is
developing
• Society, Sustainability and Civil
Engineering: A Strategy & Action Plan
• Launch – 24 April, ICE 6.30pm
© Crane Environmental
Delivering sustainable development
• Action plan builds on past work, and includes
lists of actions for four groups:
Clients
Civil engineering commercial concerns
– designers, contractors, suppliers etc
Professional and trade groups
Individuals
• including actions they need to persuade
Government to undertake
• Some examples (mostly in a UK context) …
© Crane Environmental
Delivering sustainable development
Practical actions needed:
• Re-use and improve existing built assets
• Locate new development appropriately
• Relate land-use planning to transport & other
infrastructure
• Design for minimum waste and effective use of
resources
• Choose an appropriate design life – flexible and
durable, or for dis-assembly & re-use elsewhere
• Minimise life-cycle energy consumption
© Crane Environmental
Delivering sustainable development
Practical actions needed:
• Utilise renewable energy sources where
appropriate
• Do not pollute the wider environment
• Preserve and enhance natural features and
(appropriate) biodiversity
• Conserve water resources, not all demand-led
• Respect people and their local environment,
and seek to minimise the adverse social impacts
and maximise the positive social impacts of our
projects
© Crane Environmental
Delivering sustainable development
• Scale of improvement
We need modest-scale improvements
replicated everywhere
alongside
large improvements achieved on occasional
large-scale projects
© Crane Environmental
Delivering sustainable development
Overall, we should be aiming to create
appropriate civil engineering works or buildings:
in the right place and to the right scale
with a sound choice of materials, and sources
with high environmental performance (e.g.
energy & water consumption, +ve impact,
maintainability)
an appropriate design life
in harmony with their surroundings and
neighbours
so that, asap, this way becomes our norm.

So, if that is what is needed,
How do we move practice forward?
© Crane Environmental
Delivering sustainable development
How do we move practice forward?
• Have an open mind
• A willingness to learn from each other
• Recognise that no one discipline knows best
• Consider sustainability in everything we do
• Deal more respectfully, considerately yet effectively
with all the people involved
• Accept there is no longer any excuse for doing
nothing, despite the challenges
• Accept it may take more upfront time
© Crane Environmental
Delivering sustainable development
How do we move practice forward?
• Adopt a whole life approach using life-cycle
analysis – not just life-cycle costing but life-cycle
environmental analysis as well
• Move towards sustainability impact assessment
instead of just an environmental impact assessment
• Persuade the opinion formers we know – especially
in our clients – to adopt new approaches to their
development projects
© Crane Environmental
Delivering sustainable development
How do we move practice forward?
• Use the extensive guidance already available –
from wherever on the planet we can find it
• Look for Factor 10 in all we do:
Waste dramatically less
Use dramatically less energy and water
Generate substantial improvements in
social conditions
Achieve obvious improvements in the
natural and built environments
© Crane Environmental
Delivering sustainable development
How do we move practice forward?
• Educators have a crucial role – in sending civil
engineering and other graduates in built and
natural environment subjects out into the
world understanding what sustainable
development is and how deliver it
© Crane Environmental
Delivering sustainable development
How do we move practice forward?
• By creating
appropriate engineering works or buildings
in the right place and scale
with a sound choice of materials, and sources
with high environmental performance
an appropriate design life
in harmony with their surroundings and
neighbours
© Crane Environmental
Delivering sustainable development
How do we move practice forward?
• By recognising this as a sustainable
development project:
exciting, and likely to be beautiful
highly efficient (and visibly so if possible)
in harmony with its neighbours and
surroundings and better for the businesses
involved
a joy to be in or to experience
good for the business and personal lives of those
involved
…

Delivering sustainable development
• A challenge:
“Any 21st century professional engineer who is
ignorant of, or ignores, sustainability, who does
not seek to deliver more-sustainable solutions,
and who does not also seek to live more
sustainably, will be an incomplete engineer.”
• ‘True’ or ‘false’?
