Ever wonder what keeps the Earth warm?
Energy from the sun Greenhouse gases (GHGs)

Infrared radiation

GHGs traps outgoing heat

Global Warming
 Since Industrial Revolution,

fossil fuel has been extensively used to power our homes and cars
 Excess GHGs have therefore

been released
– More heat is being trapped, causing Earth’s surface to become warmer

Feeling hot?
 Global surface temperatures have increased

by about 0.6°C (± 0.2°C) since the late 19th century
 1998 and 2005 were the warmest years on


Why should we be concerned?
 As a relatively low-lying, small island state,

global warming can affect us:
– Increased frequency and intensity of rainfall and tropical storms – Flooding, land loss and coastal erosion – Loss of water resources or seawater intrusion into fresh water bodies – Resurgence of diseases – Hotter climate

Did you know?
 Energy used to power our homes and cars

comes from fossil fuel
– Burning of fossil fuel releases GHGs as well as harmful air pollutants
 To slow down climate change:

– Use energy efficiently – Use cleaner energy

What is Singapore doing about Climate Change?

 National Climate Change Committee

– Chaired by Senior Parliamentary Secretary for the Environment and Water Resources – Tackles climate change issues Visit for more details

Key Programmes

Electricity Generation
 Market competition to promote greater energy

– Gencos switching to NG and adopting combined cycle generation technologies (CCGT)
 Cogeneration – Production of electricity and heat using the same fuel

Electricity Generation
 Test-bedding and demonstration of innovative

clean energy technologies
– Solar photovoltaics (PV) – Hydrogen fuel cells

 Energy Efficiency Improvement Assistance

Scheme (EASe)
– $10 million incentive scheme – Fund up to 50% of the cost of detailed energy audits
 Energy Audit Scheme – Encourage very large emitters of CO2 to improve their energy efficiency and energy management systems and practices  Accelerated Depreciation Allowance Scheme – Encourage companies to replace old, inefficient equipment and invest in energy-saving devices

 Curb growth of vehicle

population  Promote public transportation

Vehicle Quota System & Electronic Road Pricing

Park & Ride Scheme

 Green Vehicles

– Natural gas powered buses and taxis – Hybrid, fuel cell cars – Green Vehicle Rebates

Fuel Economy Labelling Scheme • Raise consumer awareness of fuel economy in cars • Currently, 113 car models registered

 Green Transport Week

– 20 – 27 Aug 06 – Raise awareness of fuel economy and encourage motorists to adopt climate-friendly habits

Eco Chase @ *scape
27 Aug 06 Take part in a race around Singapore using eco-friendly modes of transportation and completing eco-challenges Sign up at

 Energy Efficiency Improvement Assistance

Scheme (EASe)  Energy conservation projects  Energy efficiency improvement of public sector buildings  Energy Smart Building Labelling
– Accord recognition to buildings with good energy performance, while maintaining a healthy and productive indoor environment

 Energy labelling of household appliances – Currently, 106 air-cons and 80 fridges

 Green Corners – To increase visibility of energy labelled products

 Climate Change Awareness Programme

– Raise awareness on climate change and inculcate climate-friendly habits in households and motorists –

Reduce your GHG contribution
Here’s how …

Play a part today!
Use an electric fan

The energy used to power 1 air-con is enough to power more than 30 fans

Play a part today!
Set your air-con’s thermostat at 25ºC or 1ºC higher

Setting your air-con at 25°C gives you the most comfort at the least cost

Play a part today!
Use energy-saving light bulbs and switch off when not in use

Energy-saving bulbs use about 80% less energy without comprising on light output

Play a part today!
Don’t standby. Turn off electrical appliances and equipment at the mains
Avoid switching off using the remote control

Appliances consume power in standby mode

Play a part today!
Take public transport

MRT and buses are more energy efficient than cars and taxis

Play a part today!
Walk or cycle for short distances and when it is safe to do so

Walking and cycling is environmentally friendly, free and healthier!
