ERE's: the proof that you drive cleaner
Part of the electricity from the grid is green. For that part you drive without CO₂, and an ERE (Emission Reduction Unit) is the proof of that. Fuel suppliers buy that proof. We sell it for you and pay out 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 called an ERE certificate) is the proof that you drove without CO₂: one ERE stands for 1 kilo of CO₂ you did not emit. If you charge at home with a charging station with a built-in MID meter, every kWh yields such proof • Joulo registers it with the NEa and sells it to fuel suppliers for you. As of 9 November 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.
An ERE is not a subsidy and not an entitlement. It only comes into being after you have charged, a fuel supplier buys it and the verifier approves the registration. If one link is missing, there is no ERE.
Every sale is listed with price, volume and broker in our public sales ledger.

Fuel suppliers buy your proof
Fuel suppliers must emit less CO₂ every year. They offset their emissions with your proof: the ERE's from your charging sessions. The money comes from them, not from the government.
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
Sell and pay out
Joulo sells your ERE's and you receive the earnings • paid out quarterly.
The NEa's terms
- Metered delivery point
- A point for delivering electricity, with a vehicle connection and an integrated meter that measures the delivery. After that point nothing else uses electricity but the vehicle. For home charging that is your charging station with an MID meter inside the housing.
- Connection holder
- Whoever holds a grid connection in their name under the Energy Act. Only the connection holder can authorise a registration service provider.
- Registering (inboeken)
- Recording delivered renewable energy in the Register Energie voor Vervoer (REV). A private individual does not register themselves.
- Registration service provider
- The company that registers with your authorisation and holds its own account in the REV. Joulo is one.
- ERE-E
- The emission reduction unit for electricity: 1 kilogram of CO₂-equivalent supply-chain emission reduction, measured against the fossil reference value.
- Fuel transition obligation
- The obligation on fuel suppliers to show a fixed percentage of supply-chain emission reduction every year. They buy ERE's to meet it. That makes it a market mechanism, not a subsidy.
Why does registration take longer?
Joulo has held its own account in the REV since September 2026. Submitting electricity only opens with release 2 of that register: until then the list of energy types in the registration screen is empty. The NEa names no date. We estimate early November; that is our estimate, not the NEa's. Your charging sessions from 1 January 2026 stay recorded and go in together then.

How your earnings are calculated
Official NEa formula (RED III)
kWh × renewable% × 183 × 3.6 / 1000 = ERE's
Grid power
renewable: 50.5%
4,100 kWh → 1,364 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's. 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's up.
requirements
When do you qualify?
Four conditions decide whether your charging sessions generate ERE's.
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 person named on the connection: 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.
An ERE is not a subsidy and not free money. It only comes into being at the end of a chain: MID metering, mandate, address, verification and sale. The NEa can still correct a booking up to five years later. That is why we check everything we book. Source: the NEa guidance document for private individuals (Dutch).
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 make your own overview or report your meter reading.”
- The NEa requires sessions from your charger's software. A photo, a typed-in number or a self-made overview is rejected. An original export from your charger's app or back office is fine to send in.
- “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. If your charger had a MID meter on 1 January 2026, all your sessions from that date count, even if you sign up later.
costs
What does it cost?
Joulo charges a 20% service fee on the sale proceeds of your ERE's. No subscription, no upfront costs: you only pay when we sell. Cancel yearly, paid out quarterly. Sign up via a partner such as keuze.nl and you pay 1 percentage point less. Referral discounts are available too.

the sale
How are your ERE's traded?
ERE's are not traded on an exchange. We sell directly to a fuel supplier, sometimes via a broker. We pool the ERE's 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 ERE's 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.
Fuel suppliers, such as oil companies and fuel traders. They must emit less CO₂ every year with the fuel they sell. Your ERE's are the proof they use to compensate for it.
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 ERE's 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. See the current weekly position.
