Driving electric is about to become even more attractive. Thanks to new European regulations, EV drivers will soon be able to earn money simply by charging their car. This works through Emission Reduction Units (EREs): digital units that prove how much CO₂ you save by charging sustainably.
In this blog, we explain what EREs are, what you can earn, and which charging station you need to take part.

EREs are digital certificates that show how much CO₂ you save by charging your electric car using sustainable electricity. That saving has value, because fuel suppliers are required to compensate for their emissions. To do this, they purchase EREs. The revenue from this can ultimately flow back to you.
Every kilowatt-hour (kWh) you charge sustainably can generate EREs.
The expected return is €0.10 to €0.20 per kWh. That may sound small, but it can add up quickly. Depending on how much you drive and charge, it could amount to several hundred euros per year. And without any extra effort—because you don’t need to change your routine. You simply charge as you already do.
The trading and administration of EREs is handled by specialised service providers, so you won’t need to manage this yourself. The only thing that matters is that your charging station is able to register your official charging consumption. Without that verified registration, you simply won’t qualify for this compensation.
To earn EREs, you need a charging station with a MID-certified meter. A MID meter ensures that the charged energy consumption is officially recorded. This is required to convert your charged electricity into EREs.
As a wall-mounted charger, the Ratio io6 Pro is a strong choice for earning EREs. With the io6 Pro, you can charge on solar energy for free and earn money with EREs.
You can also use the io7 charging station - this dual charger is equipped with MID-certified meters as well.
Are you about to buy a charging station, or replace your current charge point? Then this is the moment to think ahead.
Choose an EV charger with a MID-certified meter and turn charging into a revenue model. That way, you’re ready for what’s next and you get even more out of driving electric.
