How to buy EUAs: Easy Step by Step Guide

We’ve been hearing about green finance a lot recently: impact investing has risen from US$420.91 billion in 2022 to US$495.82 billion last year according to the Impact Investing Global Market Report 2023

In this context, European Union Allowances (EUAs) are the trading unit of the EU Emissions Trading Scheme, the backbone of Europe’s climate strategy. Yet they were not accessible to individual investors in spite of being a huge, highly performing asset with a real impact on emissions and a demonstrated track record since 2005 (read more here).  Until now. 


We created Homaio to unlock this asset class for you. Homaio  is an investing platform focused on climate finance, empowering investors to seek both financial returns and proven impact on carbon emissions reduction. 

In this comprehensive guide, we'll delve into the step-by-step process of how to buy EUAs through Homaio.

Step 1: Sign up on Homaio's EU ETS platform

Here is the link to the app.

Google Authentication:

  • Use your usual Google credentials instead. By doing so, experience a faster login process with a single sign-on. Google authentication provides an additional layer of account protection while still valuing your privacy.

As part of the registration process, Homaio also requests some basic information through a brief questionnaire:

2.1 Investment Amount

Decide on the amount you want to invest in EUAs. By offering different options and entry level possibilities, Homaio wants to make sure that climate finance is within reach for all.

2.2 KYC Steps

For security and regulatory compliance, follow Homaio's Know Your Customer (KYC) procedures. This step ensures a transparent and secure investment environment. And… it is a legal requirement!

2.3 Subscription Contract Signature with Yousign

Formalize your investment through a digital signature using Yousign. We use this e-signature solution to make the process faster and more convenient for you.

Step 3: Buying Your Carbon Allowances

3.1 Monthly Batch System

Homaio has a monthly batch system - during the span of a month, we collect your orders and receive your investments. Then, we consolidate all the individual participations at the end of the subscription period and buy the corresponding EUA volumes. We buy physical (Spot) EUAs on either the Intercontinental Exchange or the European Energy Exchange. The allowances are then held on the EU Registry.

3.2 Track your investments

After buying the EUAs, Homaio grants investors access to a personalized portfolio tracker. This feature gives the opportunity to follow the investment value and observe the direct impact on reducing carbon emissions.
