Frequently Asked Questions About RECs

A renewable energy certificate, or REC, represents proof that one megawatt-hour (MWh) of electricity was generated from a renewable energy resource. In the context of Singapore, these certificates, also known as renewable energy credits, are instrumental in tracking and fostering the production of green energy across the nation.
RECs serve as a mechanism to certify and track the production of renewable energy. When green energy is generated and fed into the grid, an equivalent number of RECs are created, allowing for transparent and credible tracking of renewable energy usage.

While RECs represent the generation of renewable energy, carbon offsets are measures taken to compensate for emissions elsewhere. RECs directly support renewable energy production, whereas carbon offsets can involve various projects like reforestation or energy efficiency initiatives such as solar energy systems.

Owners of RECs can claim use of low or zero emission electricity and lower their market-based Scope 2 emissions. Carbon credits are used to offset an organisation’s overall emissions (Scope 1,2 and 3).
