What are EREs?
ERE stands for Emission Reduction Unit. Every kWh you charge at home delivers proven CO₂ savings • and you simply get paid for it.
the principle
The polluter pays
Oil companies must buy Emission Reduction Units 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.

Why a MID meter?
To claim EREs, your charger needs a built-in MID-certified energy meter. Why? Because the NEa only accepts measurement data from a calibrated meter directly attached to the charger. This makes every kWh provable and tamper-proof. Want to know if your charger qualifies? Check it via our compatibility tool.
