9. Carbon footprint What is it? Why do we need to reduce it?

10.  Total amount of greenhouse gases produced (e.g. carbon dioxide, CO 2 ) to directly and indirectly support human activities in a given time frame. What is Carbon Footprint?

11.  Carbon Emissions from public and private transport  Burning of fossil fuels to power energy plants Direct Impact from Human Activities

12.  Distance our food has to travel before it is consumed by us  Distance to deliver the clothes to us Indirect Impact from Human Activities

13. Why is it important to reduce carbon footprints?  Carbon dioxide is a form of greenhouse gases.  Traps the heat on the earth leading to global warming and ultimately climate changes.  According to report by WWF (2012), Singapore is the top carbon emitter in Asia-Pacific Thinking Question: Why do you think Singapore is the top carbon emitter in Asia- Pacific?

14.  Turn off electrical appliances when not in use e.g. television, DVD player  Carbon footprints of common electrical appliacnces How can we help to reduce carbon footprints? Appliancekg CO 2 per year Microwave Oven 39 Washing Machine 51 Electric Oven91 Standard Light Bulb 63 Low Energy Light Bulb 11 Primary TV - Plasma 10

15.  Turn down the water heating setting  Fill washing machine with a full load  Do weekly shopping in a single trip  Fit energy saving light bulbs  Take public transport / car pool  Recycle  Reduce consumption of meat How can we help to reduce carbon footprints?

16.  At the end of lesson,  Write down one thing you will do to reduce the carbon footprint Pledge to
