Frequently Asked Questions

Why was this made?

The Singapore Building Carbon Calculator is designed to improve the ease of accounting and tabulating upfront carbon in accordance with the Building and Construction Authority's Green Mark 2021 .

What data can this calculator handle?

The Singapore Building Carbon Calculator is currently in beta. Basic security features are in place for the safekeeping of your data. Please check with your project team regarding inputting project values into the calculator. We advise against inputting confidential and sensitive data. Note that no personal data is required or collected during registration or log-in.

Why use this calculator?

The Singapore Building Carbon Calculator takes into account Environmental Product Declarations (EPDs) from various Program Operators and relevant Life Cycle Assessments (LCAs). The backend data is localized to Singapore's built environment context. The calculator is supported by the Building & Construction Authority (BCA) and Singapore Green Building Council (SGBC), and is in accordance with Singapore's Green Mark 2021. On top of that, it's free!

How are the values determined?

The emission factors are tabulated based on the pre-determined global median derived from the data obtained from Environment Product Declarations (EPDs) in the material database or industry accepted databases. The Calculator also follows the Life Cycle Assessment (LCA) ISO 14040/14044 standards which are the recoginized industrial standards for the benchmarking of the environmental impacts of a building life cycle.
