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. In our most recent ERE sale (September 2026) that came to €0.123 net per kWh charged at the standard service fee. Payout follows quarterly, once the sale has settled.

the principle

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%

2,000 kWh → 665 ERE's

€260 net / year

Market price €0.49 per ERE • €0.16 gross and €0.13 net per kWh after 20% service fee. Actual market price is determined daily via OTC trading.

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.

costs

What does it cost?

Joulo charges a 20% service fee on the sale proceeds of your ERE credits. 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 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.

EREs make home charging cheaper

The ERE proceeds work as a discount on your charging costs: count on €0.12 to €0.15 net per kWh charged at home.

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.

Around €0.12 to €0.15 net per kWh charged (guide price). 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%.

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.
