CIX supports Renewable Energy Certificates (RECs) verified by internationally recognised certifiers, including I-REC (Electricity) certificates issued by the Evident Registry, ensuring transparency, credibility and alignment with global sustainability standards.
As tradeable Energy Attribute Certificate (EACs), a REC represents the attributes of one-megawatt hour (MWh) of electricity produced by renewable sources such as solar, wind, hydropower, biogas, biomass, hydrothermal, geothermal or landfill gas projects. It allows companies to make certified green claims.
Renewable sources we support
Wind
Converting wind power into electricity using modern turbines, delivering a scalable and emission-free renewable energy source.
Solar
Harnessing the sun’s energy with photovoltaic panels to generate clean electricity, ensuring a reliable and abundant renewable power source.
Biomass
RECs organic materials like wood chips, crop residues, and forest waste transformed into energy, creating a sustainable alternative to fossil fuels.
Hydropower
Generating renewable electricity from flowing water, utilising dams or run-of-river systems to provide a consistent and renewable power supply.
Biogas
Capturing methane from decomposing organic waste in farms, wastewater treatment plants and food processing facilities to produce clean energy.
Geothermal
Tapping Earth’s natural heat to generate consistent, renewable electricity and heating, regardless of weather conditions.
Landfill Gas
Harvesting methane emissions from decomposing municipal waste in landfills, turning a potent greenhouse gas into a renewable energy resource.
