REDEX

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).

APX is the issuer for the Tradable Instrument for Global Renewables (TIGR) while independent entities issue the I-REC. In Singapore, the Green Certificate Company is the I-REC issuer. Find out other issuers of the I-REC.

The I-REC(E) Registry ensures credibility through robust governance mechanisms and international recognition. The I-REC Standard Foundation administers the International Attribute Tracking Standard, which outlines the requirements for registries, participants, and issuance processes. This ensures that attribute tracking is conducted with transparency, integrity, and accuracy. The International Attribute Tracking Standard of I-REC(E) also ensures that market facilitators maintain best practices and good governance principles for the tracking instrument and the associated markets they manage. In this way, I-REC(E) can be implemented for a wide range of environmental products—not just electricity—that benefit from market confidence and independent oversight. Built as a robust and internationally standardised framework, I-REC(E) enables businesses, governments, and institutions to make…

I-RECs(E) are regulated by the International Tracking Standard Foundation in collaboration with local and national authorities. This ensures that the certificates meet stringent guidelines and adhere to international standards, providing businesses with a reliable method of certifying their renewable energy usage.

The I-REC(E) Registry is designed for key stakeholders across the renewable energy ecosystem who wish to certify, trade, or claim renewable electricity usage. Renewable energy producers, including owners of solar, wind, hydro, geothermal, and bioenergy facilities, must register as a Registrant with the local Issuer in their respective country. This allows them to officially register their production devices and request the issuance of I-REC(E) certificates, which serve as verifiable proof of renewable electricity generation. In addition to producers, the I-REC(E) Registry is open to energy market participants such as electricity suppliers, renewable energy traders, and sustainability consultants who can use I-REC(E) certificates to validate clean energy transactions. Corporate buyers and organizations focused on achieving carbon neutrality, net-zero targets, or enhancing their ESG…

An I-REC(E) interest refers to the stake a company or individual holds in promoting and utilising renewable energy. By acquiring I-RECs(E), entities demonstrate their commitment to sustainable energy practices, contributing to global decarbonisation efforts and environmental responsibility.

Purchasing an I-REC for Electricity, or I-REC(E), is pivotal for businesses aiming to authenticate their renewable energy use and reduce their carbon footprint. I-RECs(E) offer a credible and auditable means to support renewable energy initiatives, enhance corporate sustainability, and comply with international environmental standards.

The TIGR Registry ensures the credibility of Renewable Energy Certificates (RECs) through a robust auditing and verification process that aligns with internationally accepted environmental and energy standards. Each REC issued via TIGR represents 1 megawatt-hour (MWh) of renewable energy that has been independently verified by APX, providing buyers in the voluntary market with full transparency, traceability, and trustworthiness. To further support corporate sustainability claims, the TIGR Registry is officially recognised by leading global renewable energy and ESG reporting frameworks, including RE100 and CDP. This means that organisations using RECs issued through TIGR can credibly report renewable energy usage in line with international REC standards and meet their corporate sustainability initiatives with confidence.

The TIGR Registry is ideal for corporate buyers, renewable energy retailers, and project developers involved in the voluntary renewable energy market. Corporates use the platform to support their sustainability goals by purchasing and retiring credible Renewable Energy Certificates (RECs), while retailers manage RECs on behalf of clients. Project developers register their renewable energy assets to issue RECs and connect with potential buyers, investors, and lenders.

The TIGR Registry plays a pivotal role in supporting REC issuance and tracking by providing a centralised and secure digital platform for recording and managing RECs. The platform helps streamline the issuance process, ensuring accurate and reliable tracking of RECs throughout their lifecycle.
