The document discusses Singapore's efforts to promote sustainable construction practices. It notes that the construction sector accounts for 16% of Singapore's carbon emissions. Singapore launched its Green Mark scheme in 2005 to rate buildings on energy efficiency and environmental impact. The government aims to certify 80% of buildings by 2030. While green buildings have initial higher costs, they can yield 30% energy savings. The document advocates for third-party financing options like low-interest loans to help homeowners adopt green features. It also recommends educating homebuyers on long-term lifecycle costs versus just upfront costs of green buildings.
