What are International Renewable Energy Certificates?

International Renewable Energy Certificates (I-RECs) are a market-based mechanism that enables organizations to demonstrate that they are sourcing their electricity from renewable sources. I-REC digital certificates represent proof that a certain quantity of electricity has been generated from renewable energy sources, such as solar, wind, or hydro. They are issued by a registry that verifies and tracks the generation, transfer, and redemption of renewable energy attributes associated with electricity production.


I-REC Trading

I-RECs can be traded on international markets, allowing companies in regions with limited renewable energy resources to support renewable energy development in other regions. I-RECs are recognized by many international organizations and are used as a tool to measure and report on progress towards renewable energy goals, such as those set out in the United Nations Sustainable Development Goals and the Paris Agreement.


How are Renewable Electricity Markets Organized?


Renewable electricity markets typically consist of two types of buyers: those who are required to purchase renewable electricity and those who voluntarily purchase it. In both cases, buyers generally want to make a claim, or publicly state or disclose that they are purchasing or using renewable energy.

Mandatory/compliance markets exist because of policy decisions, such as state renewable portfolio standards (RPSs). RPSs require obligated electric service providers to have a minimum amount of renewable energy in their electricity supply. These policy decisions often specify eligible energy resources or technologies and describe how electricity service providers must comply. In these markets, electricity service providers use renewable energy certificates (RECs) to demonstrate compliance with mandated renewable energy requirements.

Voluntary markets, also referred to in the U.S. as “green power markets,” are driven by consumer demand for certain types of renewable energy. Voluntary markets allow a consumer to procure renewable electricity at levels above and beyond what mandatory policy decisions require and to reduce the environmental impact of their electricity use. Voluntary green power products must offer a significant benefit and value to buyers to be successful.
