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

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

Beyond the environment: the triple bottom line Living within environmental limits: Ensure natural resources to support life remain unimpaired Ensuring a strong, healthy & just society: Meet diverse needs of all; promote wellbeing, inclusion & equal opportunity Achieving a sustainable economy: Strong, stable, efficient & fair
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%

We already have the solutions
Passive Design Renewables Emissions Trading Public Transport Energy Efficiency
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

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?
