Energy Attribute Certificates (EACs)

Power Your Business with Green Electricity 

Energy Attribute Certificates (EACs) are global instruments which certify that a specific amount of electricity (usually 1 MWh) was produced from a renewable source. They come in regional variants like GoOs in Europe, RECs in North America and I-RECs internationally.  As widely recognized instruments that guarantee renewable credentials for energy, EACs are at the core of the global transition to a green energy system. 

STX is one of the largest liquidity providers in the EACs market, delivering quick and seamless execution of trades, pricing for various volumes and tailor-made solutions for businesses that need to meet their energy goals—whether voluntary or for compliance.  

Energy Attribute Certificate Systems 

EACs are a tradable commodity and comply with Greenhouse Gas Protocol Scope 2 Guidance. With the global commitment to reduce CO2 emissions by at least 45% by 2030, leveraging EACs to document your energy usage becomes a powerful way to improve sustainability.  

Globally, there are several EAC systems for claiming the use of renewable energy. In general, one EAC represents the injection of one MWh of green electricity into the grid. 


Guarantee of Origin (GoO) 

GoO is the official standard to certify the renewable origin of electricity in Europe.  

Renewable Energy Certificate (REC) 

REC is the official standard to certify the renewable origin of electricity in North America (USA and Canada).  

International Renewable Energy Certificate (I-REC) 

I-REC is the internationally used standard to certify the renewable origin of electricity.
