A Question of Ethics

Why sustainability matters
What is Sustainable Development?
“To enable all people throughout the world to satisfy
their basic needs & to enjoy a better quality of life…
…without compromising the quality of life of future
generations”
Securing the Future, UK's Sustainable Development Strategy,
HM Government 2005
Why sustainability matters: living within

Where we are now….
Where we need to be
Five principles of sustainable development
Living within
environmental limits:
Ensuring a strong,
healthy & just society:
• Respect limits of
environment, resources &
biodiversity
• Ensure natural resources
to support life remain
unimpaired
• Meeting diverse needs
of all
• Promote personal
wellbeing, social cohesion
& inclusion
• Create equal opportunity
Achieving a
sustainable economy:
Promoting good
governance:
Using sound science
responsibly:
• Strength, stability,
prosperity & equal
opportunity
• Polluter Pays
• Efficient resource use
• Participative governance
across society
• Engage people’s
creativity, energy &
diversity
• Policies developed &
implemented according to
sound science
• Precautionary Principle
• Public attitudes & values
reflected

Beyond the environment: the triple bottom line
Living within

Meet diverse needs of
all; promote wellbeing,

Global Challenges
Climate Change: Why it’s happening
• Without heat trapping “Greenhouse
gases” Earth would be 25C cooler
• Human activity is increasing levels of
greenhouse gases in atmosphere
• CO2 has increased from 280 to 380 ppm
• Rising between 2 and 3 ppm/year
• Main source is fossil fuel combustion for
energy and transport
• Average surface warming of 1 to 6C
expected
What’s at stake: projected global risks
Monbiot: 90% cut by 2030
Tyndall: 90% cut by 2050
UK Gov: 60% cut by 2050
• Rice yields fall 15%
• Increasing extreme weather
events
• Indian Ocean coral dies
• 400m extra in water stress
• 5m extra in hunger
• 18% species loss
• Greenland icecap melts
o
1 C
• 97% coral reefs bleach
• Major city flood risk
• Arctic summer sea ice melts • >50% species loss
• 2.3-3bn water shortage
• “Runaway” climate change
• 200m more at risk from
- Forest die-back
malaria
- Permafrost melt
• Ecosystem collapse
- Carbon release from soils
• Human cost?

Pollution: damaging health and the environment
• “UK air pollution more dangerous than Chernobyll”
• 24,000 premature deaths per year (Royal Commission on
Environmental Pollution)
• Over 100,000 man-made chemicals exist
• Only 3,500 have been adequately tested for health and
environmental impacts
• Over 300 man-made chemicals can be found in the
average European’s blood
• With globalisation, Europe is exporting its pollution
overseas

Global Inequality
Poverty: an ever widening gap
UK average high
street coffee price
$2
20% of world
survives on less
than $2 per day
Biodiversity: the sixth extinction
• Up to 50% of species could be wiped out by
climate change
• Widespread decline in wildlife populations
•
•
•
•
Habitat destruction and loss of wilderness
Over-harvesting of timber, fisheries
Falling fertility from pollution
Invasion of alien species
The goal: One planet living
• Ecological footprint = equivalent
area of land required to meet an
individual’s needs
• Food, fibre, waste, energy,
space
• Measured in “Global hectares
per capita” (gha)
“Equal sustainable share” = 1.8 gha
“Global average footprint” = 2.2 gha
“UK average”
= 5.6 gha
Group Exercise
Coffee Cup Exercise
• Work as groups
• First map out the lifecycle of a cup of
coffee:
• From raw materials to disposal!
• Identify impacts
• Social, environmental and economic
• How can this be improved?
