- Companies use Renewable Energy Certificates (RECs) to substantiate their use of renewable electricity, for the purposes of greenhouse gas emissions reporting and meeting sustainability targets. To provide greater clarity on how the different types of RECs can be used to support claims of renewable energy usage, Enterprise Singapore (EnterpriseSG), through the Singapore Standards Council (SSC), together with the Ministry of Energy, Trade and Industry (METI) and the Energy Market Authority (EMA), have updated the Singapore Standard (SS) 673: Code of Practice for RECs.
- The updated SS 673 specifies the types of RECs that can support claims of renewable electricity consumption in Singapore. In line with the amendments, companies making claims of renewable electricity usage should use RECs linked to renewable electricity supplied to Singapore's power grid. These include RECs from renewable electricity generated in Singapore, such as solar energy, as well as RECs from approved low-carbon electricity import projects.
- RECs from other overseas renewable energy projects that do not supply electricity into Singapore may still be purchased to support renewable energy development and regional decarbonisation efforts – but should not be used to support claims of renewable electricity usage in Singapore. See Annex A for more details.
- First launched in 2021, SS 673 provides a framework to improve the integrity of measurement, reporting and verification (MRV) requirements for the issuance and management of RECs. It supports the credible and consistent use of RECs among energy users by setting out good practices for REC transactions and claims.
- The amendments to SS 673 were developed by a public-private Working Group appointed by the SSC and overseen by EnterpriseSG, comprising representatives from government agencies, industry associations, renewable energy market participants and corporate REC users. The amendments also underwent public consultation before being finalised. EnterpriseSG, through the SSC, will continue to work with industry stakeholders to review and enhance SS 673 as technologies, market practices and international standards evolve.
- The list of amendments to SS 673 can be downloaded free of charge from the Singapore Standards e-shop. The updated 2026 edition of SS 673, which incorporates the amendments, can be purchased from mid-November onwards.
