Global Warming - Mitigations
• Low carbon green growth economy• Energy efficiency, conservation efforts• Introduce carbon tax system• UN climate change initiatives• Kyoto Protocol expires in 2012• New Protocol in Copenhagen, Dec. 2009
Copenhagen Protocol
• UNFCCC (Framework Convention on Climate Change)
• 192 Member States (S/N Korea 포함 )• COP-15 held in Copenhagen, Dec. 2009• New legally binding protocol by 2012• Each MS commits to GHG emission level• Major polluters expected to ratify
Global Warming Summary
• Mechanism : CO2 greenhouse gas from burning fossil fuels
• Consequence : climate change, ecology disruptions• National strategy : low carbon, green growth
– Post-Kyoto, Copenhagen Protocol – Carbon tax, credit trading– Develop alternate energy sources
• Personal strategy– Energy conservation, back to nature
Alternatives to Fossil Fuel Energy
• Electricity– Present: coal, oil, hydro, nuclear, natural gas– Alternate: wind, solar, tidal, fusion
• Transportation– Present: oil, coal– Alternate: electric, hybrid, hydrogen
• Process heat, space heating– Present: coal, oil– Alternate: high efficiency, insulation

Renewable Carbon-free Energy Alternatives
• Hydro power– Potential sites already developed
• Wind power– Low energy density, site limitations, expansion
• Solar power– High capital cost, site limitations, expansion
• Tidal power– Very high capital cost, only special sites

Emissions ReductionEmissions Reduction
10 Personal Conservation Means (1)
• Change light bulbs– From regular bulb to fluorescent light– 1 bulb effect : 70 kg CO2 savings/year
• Drive less– Walk, bicycle, metro subway, public trasport– Every 10 km not driving: 4 kg CO2 savings
• Recycle more– Home garbage separation for recycle– Half recycle: 1200 kg CO2 savings/year/house
10 Personal Conservation Means (2)
• Check your tire air pressure– Proper pressure ~3% better gas milage– 1 liter fuel saving: 3 kg CO2 savings
• Use less hot water– Save hot water while shower, washing
• Avoid products with a lot of packaging– Resource conservation, reduce wastes
• Adjust room temperatures– Summer less air-con, winter 1-2 degrees lower
• 1,000 kg CO2 savings/year/house
10 Personal Conservation Means (3)
• Plant a tree– 1 tree : 1 ton CO2 absorption/30 yearTurn off electric devices– Unused lights, TV, PC, DVD, stereo etc.
• Be a part of the solution– www.ClimateCrisis.net
