Note also Singapore's switch from fuel oil to natural gas for generating electricity, use of natural gas in public transport, implementation of the emission-based vehicle tax (to encourage use of energy-efficient cars which emit less CO2), and BCA Green Mark (which can involve the use of solar panels, LED lights, etc.) as our steps in going green.
