We provide a centralised liquid marketplace for the purchase of Renewable Energy and Energy Attribution Certificates including GOs, REGOs, RECs and I-RECs.

PPA/GPA – Power/Gas Purchase Agreement

A PPA (Power Purchase Agreement) or GPA (Gas Purchase Agreement) is a bilateral agreement between a generator and energy supplier or end user. It is an agreement to purchase and deliver an amount of physical or virtual power or gas at a set time or on a continuous basis. A PPA/GPA can be virtual where no physical delivery of electricity or gas is delivered just a financial swap, and there is a physical PPA/GPA where the contract describes a physical transaction of gas or electricity between generator and buyer via the grid.

Guarantees of origin Europe

AIB Members


Guarantee of Origin certificates (GOs) are renewable power certificates that can be used to document and report on the energy you consume that comes from a renewable source. They are part of a voluntary system that complies with the Greenhouse Gas Protocol Scope 2 Guidelines. They are widely used in the European Union to reduce your greenhouse gas emissions and increase your sustainability ratings. They can be used as verifiable documentation for a sustainability or environmental report. The money used in the sale of these certificates is used by renewable energy generators to expand and develop current and new renewable production. Each certificate corresponds to 1MWh of renewable electricity bought or supplied.  AIB maintain the AIB hub, providing secure interregistry communication between AIB countries.

The Association of Issuing Bodies (AIB) promotes the use of a standardised system, based on harmonized environment, structures, and procedures to ensure the reliable operation of international energy certificate systems.[
A Guarantee of Origin (GO) is an energy certificate defined in article 15 of the European Directive 2009/28/EC. One GO certificate corresponds to 1 MWh of generation and is traded on the OTC market.
A REGO (Renewable Energy Guarantee of Origin) is a certificate similar to the Guarantee of Origin certificate but used in the United Kingdom. Renewable electricity Generators in the UK if registered with Ofgem can produce an amount of these certificates corresponding to their power output. REGO certificates provide transparency on the electricity supplied coming from the National Grid. For 1MWh (megawatt hour) of renewable electricity produced one REGO certificate is issued by Ofgem to the generator of that electricity.
REC or Renewable Energy Certificates are certificates produced by renewable electricity generators that can be used to prove the green or renewable source of the electricity that someone is buying. Each REC certificate counts for 1MWh of renewable electricity produced and can be used for sustainability and environmental reports. They work the same way as I-RECs, Guarantees of Origin but are used in the United States. RECs are redeemed on an electronic registry and can only be done so once; this disables any possibility of double counting.
I-REC, International Renewable Energy Certificates are similar certificates to the European Guarantee of Origin Certificates. The I-REC standard is a rapidly growing scheme established in Asian, African, Middle Eastern and Latin American countries. The figures below show over 51 countries that take part in this scheme.

Carbon offsetting

A voluntary carbon credit (VER) is a non-mandatory emission reducing credit that can be used offset one’s carbon footprint.

Compliance carbon (CER) markets are heavily regulated by various geopolitical jurisdictions. European Union Allowances are the main form of offsetting in the EU Emissions Trading Scheme (EU ETS).

As a viable and cost-effective means to reduce global emissions of greenhouse gas emissions, carbon trading is an ever-growing part of the international, national, and local approach to tackling climate change. We advise clients on market developments and risk management. 

From trade execution in highly liquid allowance markets to the structuring of long-term carbon credit transactions, our Carbon Markets teams in London can meet your risk hedging and market access needs.
