ERE glossary

New to the world of ERE? Below we explain the terms you'll come across when comparing booking service providers and earning from your charging station.

ERE (Emission Reduction Units)

The Dutch unit for demonstrable CO2 reduction through renewable energy in transport. Since 1 January 2026 the successor to the HBE, with the emphasis on actual CO2 savings. Anyone who charges green electricity can have ERE units registered and sold.

HBE (Renewable Fuel Units)

The predecessor of the ERE. As of 1 January 2026 the Netherlands switched from HBE to ERE; existing HBE balances are converted to ERE units by the NEa.

Booking service provider ("inboeker")

A company registered with the NEa that collects the charged kWh from charge points, converts them into ERE units and sells them on your behalf on the emissions market. You receive a reward in return.

NEa (Netherlands Emissions Authority)

The regulator that sets the rules for ERE units and registers and supervises the booking service providers.

Commission

The percentage the booking service provider withholds from the proceeds of your ERE units, as a fee for registration, auditing and administration.

Service costs

Fixed or periodic costs a booking service provider may charge on top of the commission. The comparison tool shows the net result after deducting both commission and service costs.

Payout frequency

How often a booking service provider pays out your reward, for example monthly, quarterly or annually.

Contract term (duration)

The period for which you enter into a contract with a booking service provider. ERE-Vergelijk supports fixed terms of 1 to 5 years.

Smart charging (smart charge point)

A charge point connected to the internet that automatically records charging behaviour and reports it to the booking service provider. Some services require a smart charge point.

MID meter

A meter that complies with the European Measuring Instruments Directive (MID) and is therefore certified for reliable kWh registration. A MID-compliant measurement is required for valid ERE booking — use the MID Checker to see whether your charge point qualifies.

Emissions market

The market on which ERE units are traded. Fuel suppliers buy ERE units to meet their statutory obligation; the market price partly determines your reward per kWh.

Fuel transition obligation (BTV)

The Dutch obligation (since 1 January 2026, based on the European RED III directive) requiring fuel suppliers to increase their share of renewable energy. ERE units are the proof of that CO2 reduction.

kWh (kilowatt-hour)

The unit in which charged electricity is measured. The more kWh you charge green, the more ERE units you can generate and the higher your reward.
