◦
◦
◦
Average footprint
Developed world resource use
Developing world resource use
Need for food, transport, energy use,
agriculture, deforestation
◦ Population growth
◦ Speed in which it takes to regenerate
what we use in a year
12. Impacts of Environmental
change

change
Global temperature rise
Natural reasons (solar cycles, volcanoes etc…)
Man-made reasons (emissions, change in land use
etc…)

Carbon footprint increased by 12%
over period
15. Impacts of Environmental
change
Major Impacts:
◦
◦
◦
◦
◦
◦
◦
◦
◦
Global warming
Sea level rise
Ocean acidification
Health
Temperature rise
Extreme weather events
Deforestation
Ecosystem strain
Loss of biodiversity
16. Global Warming
The main cause of global warming is the
emission of ‘greenhouse gases’ such as
carbon dioxide, methane and nitrous oxide.
Human activity over the past 250 years,
including the burning of fossil fuels, change
of land use and agriculture, has increased
the concentration of greenhouse gases in
the earth’s atmosphere.
As these gases build up in the atmosphere
they strengthen what is known as the
‘greenhouse effect’.
17. Global Warming
There has been a clear decreasing trend in Arctic
summer sea ice levels since records began in
1979.
Sea level around the Uk rose by 10cm during the
20th century.
The Earth’s surface has warmed by 0.4 C on
average since the 1970s, 1 C in last 100 years.
In 160 years of records the hottest years have
been since 1997.
18. Group Exercises
Identify the following;
Commonly used resources
How resource efficiency affects climate
change
Reasons why a business should be
resource efficient
GROUP TASK 3
19. Commonly used resources
Renewable
Non-renewable
◦ Can be replenished
through biological or
natural processes
◦ Solar
◦ Wind
◦ Tides
◦ Hydro power
◦ Biomass (plants, trees etc,
when harvested
sustainably)
◦ Food stuffs
Cannot be grown,
replenished in the same
rate it is consumed
Fossil fuels
◦ Coal
◦ Gas
◦ Oil (fuel, petrol etc)
Radioactive fuel
Metals
20. A few facts
We throw away more than 7 million tonnes of
food and drink every year from our homes most of which could have been safely
consumed.
By pursuing opportunities for re-use, the UK
could reduce its reliance on raw materials,
including rare earths, by as much as 20% by
2020.
Our research shows doubling the number of
sofas re-used, could save 52,000 tonnes of
CO2 equivalent. At the moment, 83% of
sofas are not re-used and are sent to landfill
or recycled.
Tip of the iceberg……
21. Links between resource
efficiency and climate change
Emissions of greenhouse gases
from manufacturing, agriculture,
transport, forestry, aviation,
shipping
Embodied energy
◦ Total sum of energy to produce
Emissions from
◦ waste
◦ transport
◦ energy use
Transfer of greenhouse gases
from one part of a cycle to
another e.g. hybrid cars reduce
fuel consumption but use
inefficient coal fired power
stations to charge batteries
22. Business Reasons for Resource
Efficiency
Regulation and
legislation
Reputation
Cost reduction
Staff retention
Profitability
Development of
industrial capability
Standard of living in
less developed
countries
23. Reduce, Reuse, Recycle
In order to minimise the impact of
waste products on the environment
there are actions that we can take by
reducing what we use, reusing
products and recycling waste.
In groups complete the ‘waste
hierarchy’ activity and then feedback
your answers to the other groups
25. Group Exercises
Identify the following;
Ways to reduce consumption of
commonly used resources
Ways to reuse commonly used
resources
Identify recyclable resources
GROUP TASK 4
26. Waste Types
Hazardous
Waste which may contain hazardous substances,
may cause harm to the environment or react with
other materials
Non-Hazardous
Soils, builder materials, sludge, inert materials
Clinical/Biological
Sharps, infected material, some hospital waste,
waste from surgeries hospitals and clinics,
infectious organisms, absorbent materials, human
and animal tissue
Inert and Active
Building waste such as rubble, bricks, stone (Inert)
and wood, old window frames, guttering, pipework,
downspouts and other building related matter
(Active)
28. Ways to reduce….
Boil only water you need
Buy only what you need
Buy things with less packaging
Cook food for only those eating
Switch off lights, monitors, appliances
Print on both sides of paper
Flush toilet only when needed
Solar power
Insulation in homes
Service vehicles and equip regularly
Use public transport
Walk…
29. Ways to reuse….
New ways of using materials
Reuse wrapping, boxes, plastic
bags
‘Bag for life’
Repair rather than dispose
Composting (paper, wood, food)
Chip fat from local chip shop used
as diesel
Sell unwanted items
Re-use coffee cups
Print on both sides
Rechargeable batteries
Grey water harvesting
Rain water harvesting
31. Recycling materials into.....
Paper
More paper, depending on quality – 7 times
Cardboard
Paper, jiffy bags, loft insulation, car bodies, packaging, animal bedding,
coffins
Cans
New cans, car and aviation , bike frames, train tracks, pipes. Never loses
quality
Plastics
new bottles, car parts, bins, home composters . It can also be used to make
clothing such as fleece jackets and hats or fibre filling for sleeping bags and
duvets. Plastic milk bottles are used in street and garden furniture
Glass
Reused where possible (brown, clear) or crushed and turned into fine sand to
be used as building sand, if processed further can be used as floor and wall
insulation and lightweight construction aggregate.
Tyres
Surfaces for playgrounds, shock absorption, car parts, retreads, fuel, mulch
for landscaping, 3G sports pitches
33. Practice Questions
Complete the crossword and the
