International Renewable Energy Certificates


I-REC Standard_logo.jpg

The International REC Standard (I-REC Standard) is a non-profit organization aims to spread the principles of energy attribute tracking systems (REC systems) worldwide. This is to promote a consistent and verifiable product that enables a reliable and transparent consumer choice for renewable electricity in all regions of the world.

The fundamental purpose of introducing I-REC is to provide a market instrument for consumers in the markets without their own energy attribute tracking system. For example, there is no available tools in some Asian countries such as China, Southeast Asian countries like Thailand and Malaysia, as well as some Central and South American countries.

As the first market player based in Asia, Mt.Stonegate has been active in Asian and Southeast Asian countries ever since I-REC is available. Furthermore, our Managing Director Jules Chuang is one of the founder and board member of I-REC Standard. We are also working closely with the Chinese authorities to explore the possibilities of I-REC in China ( For more details please go to:

I-RECs are recognized and endorsed in the Greenhouse Gas Protocol Scope 2 Guidance document, CDP technical guidelines and sustainability surveys as well as RE100 methodology and technical papers.
