ERE credits: how home charging earns you money
Every kWh you charge at home avoids CO₂. We sell that saving as EREs (Emission Reduction Units) and pay out the proceeds to you every quarter.
A built-in MID meter on your charger is required for participation. Compare brands in the MID charger check, or run the charger check for your setup.
Joulo handles the entire registration as your ERE service provider. Want to start right away? See how ERE registration works at Joulo.

the short answer
An ERE (emission reduction unit, also known as an ERE credit) is a tradable proof of 1 kilogram of avoided CO₂ chain emissions. If you charge at home on a charger with a built-in MID meter, every kWh you charge earns EREs • Joulo registers them with the NEa and sells them for you. As of 12 October 2026, Joulo customers receive on average 12.6 cents net per kWh, and 12 cents at the standard 20% service fee. Source: the public sales ledger, 8 sales. Payout follows quarterly, once a sale has settled.
Every sale is listed with price, volume and broker in our public sales ledger.

The polluter pays
Oil companies must buy ERE's to offset their pollution. That money goes to people who do charge clean • like you. No subsidies, no hassle.
the process
How it works
Step 1
Charge
You charge your car at home. Your charger tracks how much you charge via the built-in MID meter.
Step 2
Register
Joulo automatically registers your kWh with the NEa. You don't have to do a thing.
Step 3
Earn
Joulo sells your EREs and you receive the earnings • paid out quarterly.
the calculation
How your earnings are calculated
Official NEa formula (RED III)
kWh × renewable% × 183 × 3.6 / 1000 = ERE's
Grid power
renewable: 50.5%
4,200 kWh → 1,397 ERE's

net / year
Our 8 sales averaged 15 cents gross per kWh. Our customers keep 12.6 cents net per kWh of that on average, after the service fee they actually pay. At the standard 20% fee it is 12 cents.
the scheme
From HBE to ERE: what changed in 2026
Until 2026 the unit was called HBE: Renewable Fuel Unit. Since 1 January 2026 the law targets avoided CO₂ instead of delivered renewable energy. The new unit is the ERE: Emission Reduction Unit.
One ERE represents 1 kilogram of avoided CO₂ in the chain, compared with fossil fuel. At the conversion on 1 May 2026 every HBE became 46 ERE credits. The NEa (Dutch Emissions Authority) runs the register.
New since 2026: home chargers take part too. The obligation for fuel suppliers has existed since 2015, but until 2025 only companies and charge point operators could register. Fuel suppliers must show 14.4% emission reduction in 2026 and 28.4% in 2030. That rising obligation keeps demand for ERE credits up.
requirements
When do you qualify?
Four conditions decide whether your charging sessions earn ERE credits.
Factory-fitted MID meter
Your charger has a built-in, MID-certified meter. A separate sub-meter in the fuse box does not count. No MID? Then upgrade to a charger with a MID meter, or request a Secondary Allocation Point (SAP) from your grid operator.
Energy contract in your name
The EAN code of your connection is in your name. Driving a lease car? The payment goes to the holder of the energy contract: you as the resident, not the lease company.
One registration provider per connection
You authorise one registration provider for your EAN. Switching is possible, double registration is not. So choose deliberately.
Retroactive to 1 January 2026
Sessions since 1 January 2026 count, as long as the MID meter measured them. Sessions from before your MID meter never count, not even retroactively.
What you read everywhere, and what's true
- “You have to share a photo of your charger.”
- A photo shows no address. The NEa does not accept it as proof that your charger is at your address.
- “You have to provide an installation invoice.”
- Allowed, not required. It is one of three proofs of your address. A printout from your charger's app with the address also works, and for many brands we fetch the address ourselves.
- “You can supply your charging data yourself or report your meter reading.”
- The NEa requires sessions from your charger's software. A photo or a typed-in number is rejected.
- “You give an estimate of your kWh per year.”
- You register what the meter measures, session by session. An estimate counts for nothing.
- “A MID meter in the meter cupboard usually doesn't qualify.”
- For home charging never, not usually. Your charger itself must have a MID meter.
- “Sessions from before your MID meter still count.”
- Counting starts at the MID meter. What was charged before never counts later.

the sale
How are your ERE credits sold?
ERE credits are not traded on an exchange but via brokers. We pool the credits of all our customers and sell every quarter. That volume gets us a market price a single household could not reach alone.
Every sale is listed in our open sales log: date, volume, price and broker. So you see exactly what your credits fetched and what you keep net.

Why a MID meter?
The NEa only accepts measurement data from a calibrated MID meter built into your charger. That makes every kWh provable. Use our compatibility check to see if your charger has one.

Frequently asked questions
Our customers receive 12.6 cents net per kWh charged on average; at the standard 20% fee it is 12 cents. How much that is per year depends on how much you charge; for residential users the grid average (50.5% renewable) always applies. Use our calculator to estimate your personal earnings.
Oil companies and fuel traders. They are legally required to offset their CO₂ emissions by purchasing Emission Reduction Units.
Signing up takes 5 minutes. Joulo handles the NEa registration for you. Payouts happen every quarter.
We read your charger data, register your kWh with the NEa, have the data audited by an independent verifier, sell the EREs on the market and pay you out. All you need to do is charge. Service fee: 20%.
Not always. Some providers apply their service fee to the proceeds after transaction, verification or administration costs. The quoted amount per kWh is then higher than what you receive. So ask: net per kWh after all costs, and when it lands in your account. At Joulo nothing comes off first: 12.6 cents is what our customers keep on average, paid out every quarter.
Your charging sessions and ERE registrations are kept for at least 5 years from the calendar year of registration, as required by the Regeling energie vervoer. This allows the NEa to audit or correct a registration up to 5 years back. For invoices and payouts the fiscal retention period of 7 years applies.
RaboResearch explains in a 20 May 2026 analysis that demand for ERE-Es from electric road transport will rise through 2030: the land subsector must achieve a 28.4% greenhouse-gas chain emission reduction, with a gap of roughly 13% that has to be filled primarily with ERE-Es and ERE-Gs. At the same time, the exact ERE price cannot be guaranteed in advance, and what applies after 2030 is not yet fixed. We use no fixed rates, only market price minus service fee.
