With our unique position within the building and construction industry, SGBC can provide relevant resources to help organisations and individuals to build green.


Buildings account for over 20 percent of Singapore’s carbon emissions. As such, greening our buildings is a key strategy to achieving our Singapore Green Plan 2030 goals and fulfilling our international commitments toward mitigating climate change. Under the Singapore Green Building Masterplan, ambitious sustainability targets have been set for the next lap of our green buildings. The revised Green Mark scheme (GM: 2021) implemented on 1 November 2021, aims to mitigate the effects of climate change through driving energy efficiency and carbon reduction, as well as other measures that address key sustainability drivers.

In collaboration with BCA and SGBC, JTC has commissioned NUS-ESI to develop a unified Building Embodied Carbon Calculator (BECC) which has replaced the BCA carbon calculator. It is customised for local industry use and includes key features such as accounting for upfront carbon of materials used with adapted carbon emission factors to reflect the carbon footprint of projects within the local context. The implementation of the BECC would provide the industry with a unified tool to make informed decisions on material and product selections to reduce the carbon footprint of projects for use under the Sustainable Construction section of the Code for Environmental Sustainability of Buildings (Edition 4.0) and the Green Mark 2021 Whole Life Carbon badge.

The BECC is aligned with the SGBC’s growing emphasis on reducing and optimizing carbon emissions through upskilling of industry professionals’ carbon capabilities and developing an ecosystem to raise the adoption rate of environmental product declarations (EPD) to support the built environment’s transformation to one that is greener, healthier and low-carbon.
