2026 environmental malus calculator
Calculate the French CO₂ malus and weight malus in real time using the official 2026 grid: WLTP thresholds, weight-based taxation, allowances and exemptions taken into account automatically.
Step 1 · Vehicle profile
Statutory allowances change the amount due dramatically: a plug-in hybrid can see its weight malus cut in half.
From 3 dependent children (vehicle with ≥ 5 seats): − 20 g/km of CO₂ and − 200 kg per child. Since 1 July 2026, an electric vehicle without the minimum environmental score is subject to the weight malus with a 600 kg allowance.

Weight malus scale
Progressive rate: only the fraction of the mass falling within a band is taxed at that band's rate.
| Kerb weight | Rate |
|---|---|
| Up to 1 499 kg | 0 €/kg |
| From 1 500 to 1 699 kg | 10 €/kg |
| From 1 700 to 1 799 kg | 15 €/kg |
| From 1 800 to 1 899 kg | 20 €/kg |
| From 1 900 to 1 999 kg | 25 €/kg |
| From 2 000 kg upwards | 30 €/kg |
Allowances on the mass
- • Mild hybrid or non plug-in hybrid: − 100 kg
- • Plug-in hybrid, electric range > 50 km: − 200 kg (capped at 15 % of the mass)
- • Plug-in hybrid, range ≤ 50 km: − 100 kg, like an ordinary hybrid
- • Eligible electric and hydrogen: exempt from both malus
- • Electric without environmental score: − 600 kg (since 1 July 2026)
- • Large family (≥ 3 children, vehicle with ≥ 5 seats): − 200 kg and − 20 g/km per child
How to calculate the 2026 malus?
- 1 Check the WLTP emissions in field V.7 of the registration document (carte grise) or on the manufacturer's spec sheet.
- 2 Identify the kerb weight in field G, which determines the weight malus bands.
- 3 Apply the allowances 100 or 200 kg depending on hybridisation, 600 kg for an EV without the environmental score.
- 4 Check the exemptions disability, large family, hydrogen, specific imports.
Key facts about the scale
Entry threshold
108 g CO₂/km gives 50 €. Any value below or equal to 107 g remains exempt.
Critical zone
Between 150 and 180 g/km, the increase exceeds 4 000 € for every 10 g.
Weight malus
Taxed band by band from 1 500 kg, up to 30 €/kg above 2 000 kg.
Legal cap
80 000 € for the combined CO₂ + weight malus, up to and including 2027.
2026 reliefs
Official exemptions and allowances
Measures granted upon administrative application.
People with disabilities
Full exemption for vehicles owned by wheelchair users, holders of a French inclusive mobility card (carte mobilité inclusion, disability category) or of a military disability card, as well as by the parents of minor children in that situation.
Hydrogen vehicles
Full exemption from both the CO₂ malus and the weight malus throughout 2026.
100 % electric vehicles
- Until 30/06/2026: full exemption from CO₂ and weight malus.
- Since 01/07/2026: 600 kg allowance on the weight malus for models that do not reach the minimum environmental score.
Hybrids and large families
- Ordinary hybrids and PHEV ≤ 50 km: 100 kg allowance.
- PHEV > 50 km: 200 kg allowance, capped at 15 % of the mass.
- Families (≥ 3 children): reductions on both malus, upon application.
Cap: up to and including 2027, the combined CO₂ malus + weight malus never exceeds 80 000 €. Source: 2026 Finance Bill, scale applicable since 1 January 2026. Scale last checked: .
Frequently asked questions
2026 environmental malus FAQ
What is the 2026 environmental malus threshold?
The 2026 environmental malus starts at 108 g of CO₂/km WLTP for an amount of 50 €. Every additional gram increases the tax up to the 80 000 € ceiling, reached from 192 g/km. A vehicle emitting 107 g/km or less is not taxed.
How do the CO₂ malus and the weight malus add up?
Both taxes are cumulative, but the total stays capped at the maximum CO₂ malus, namely 80 000 €, until the end of 2027. A heavy vehicle whose CO₂ malus already reaches the cap will therefore pay nothing more on account of its mass.
From what weight is the weight malus due in 2026?
The weight malus is triggered above 1 500 kg of kerb weight (masse en ordre de marche). The rate is progressive, band by band: 10 €/kg from 1 500 to 1 699 kg, 15 €/kg from 1 700 to 1 799 kg, 20 €/kg from 1 800 to 1 899 kg, 25 €/kg from 1 900 to 1 999 kg and 30 €/kg from 2 000 kg upwards. Only the fraction of the mass falling within a band is taxed at that band's rate.
What allowance applies to a plug-in hybrid in 2026?
A plug-in hybrid with an urban electric range above 50 km benefits from a 200 kg allowance on its kerb weight, capped at 15 % of that weight. Below 50 km of range, it falls under the ordinary hybrid regime, i.e. 100 kg, like a non plug-in hybrid or a mild hybrid. This allowance only affects the weight malus: the CO₂ malus is still calculated on the actual WLTP emissions.
What malus reduction applies to large families in 2026?
From 3 dependent children onwards and for a vehicle with at least 5 seats, the emissions taken into account are reduced by 20 g/km per child and the weight taken into account by 200 kg per child. For 3 children, that means 60 g/km and 600 kg less. The reduction is claimed after registration, once every two years.
Which vehicles are exempt from the 2026 malus?
Hydrogen vehicles are exempt all year round. Battery electric vehicles were exempt until 30 June 2026; since 1 July, those that do not reach the minimum environmental score are subject to the weight malus with a 600 kg allowance. People with disabilities and large families can apply for an exemption or a refund.
