2026 Environmental Malus Calculator

Simulate the French CO₂ tax and the new weight-based malus in real time using the official 2026 grid. Optimised for WLTP thresholds and the latest finance bill.

2026 malus grid: what the Finance Bill changes

This tool replicates the full 2026 environmental malus tax: a lower trigger point at 108 g/km, euro-by-gram progression, a weight penalty from 1,500 kg and a legal ceiling of €80,000. Content is refreshed after each government announcement (Finance Bill 2025, Lecornu II adjustments).

  • CO₂ scale

    Instant feedback for every WLTP gram, from 108 to 250 g/km.

  • Weight malus

    Step-by-step computation for each 100 kg bracket above 1,500 kg.

  • Exemptions

    Summary of 2026 allowances (EVs, hybrids, large families, disability status).

How to compute the 2026 malus?

  1. Check the WLTP emissions shown in field V.7 on the French registration document or on the OEM spec sheet.
  2. Find the kerb weight (field G) to determine how many weight brackets apply.
  3. Apply possible allowances (600 kg for EVs during H2, 100–200 kg for hybrids).
  4. Verify exemptions: disability status, large families, hydrogen cars, specific imports.

Key facts about the 2026 scale

Entry threshold
108 g CO₂/km ⇒ €50. Anything ≤ 107 g stays at €0.
Critical zone
Between 150 and 180 g/km, the tax increases by more than €4,000 every 10 g.
Weight malus
Each 100 kg segment above 1,500 kg is charged, reaching €30/kg above 2,000 kg.
Legal cap
€80,000 for the CO₂ + weight malus combo (cap applicable until 2027).

Tip: combine this simulator with OEM configurators to shortlist engines below the steep brackets.

Frequently asked questions

2026 environmental malus FAQ

Quick answers before registering a new vehicle.

What is the 2026 malus threshold?

The tax starts at 108 g/km WLTP for €50. Each extra gram pushes the amount up to the legal €80,000 ceiling at 192 g/km. Cars at 107 g/km or below pay nothing.

Can the CO₂ malus exceed the weight malus?

Both amounts add up but the total cannot exceed €80,000. Example: if a heavy SUV already reaches €80,000 with the CO₂ scale, the extra weight tax is not billed beyond that limit.

Who can apply for an exemption in 2026?

Hydrogen cars remain fully exempt, EVs get a 600 kg allowance during H2, while disability card holders and large families may request partial or total refunds.
