Quick answer

## How to buy Guarantees of Origin in practice.

 To buy Guarantees of Origin, first define the country or market, certificate system, volume, production period, technology, delivery timing, and documentation needs. Then use an RFQ or marketplace workflow to compare available offers and move qualified opportunities forward.

 If the buying need is European, review the [EECS guide](https://www.greenpowerhub.com/eecs?hsLang=en). If the need is broader than Europe, start from the [GO and EAC hub](https://www.greenpowerhub.com/guarantees-of-origin?hsLang=en) or use the [coverage lookup](https://www.greenpowerhub.com/platform/certificate-markets?hsLang=en).

Buying steps

## Five decisions to make before asking for GO offers.

 A clear buying brief helps sellers respond with comparable offers and reduces the risk of confusing certificate markets, vintages, or claim requirements.

Step 1

### Confirm market fit

 Check country, scheme, and whether the buyer needs GOs, EECS, REGOs, I-RECs, RECs, or another EAC.

Step 2

### Define attributes

 Set volume, production period, vintage, technology, labels, and delivery expectations.

Step 3

### Create an RFQ

 Structure the request so sellers respond against the same criteria.

Step 4

### Compare offers

 Review price, counterparty fit, delivery route, documentation, and next-step timing.

RFQ workflow

## Use an RFQ to compare GO offers clearly.

 RFQs are useful when buyers need sellers to respond to the same certificate requirements. They help organize country, scheme, volume, vintage, technology, timing, delivery route, and documentation needs.

 GreenPowerHub can support buyer workflows from requirement setup to offer review and opportunity handoff.

Market choice

## When to use GOs, EECS, I-RECs, REGOs, or RECs.

 Guarantees of Origin is often used as a broad search term, but the actual certificate route depends on the consumption country, market rules, and intended claim.

 Do not treat every renewable certificate as interchangeable. Check the market first, then choose the right sourcing workflow.
