The penalty mechanism in one sentence
Every manufacturer of new passenger cars sold in the European Union has a specific CO2 emissions target (g CO2/km, fleet-weighted by mass); for every gram per kilometre above that target, the manufacturer pays 95 EUR per vehicle registered that calendar year, with no deductibility.
The legal basis is Regulation (EU) 2019/631 (as amended), Article 8. It replaced Regulation (EC) 443/2009. The same architecture applies to light commercial vehicles (vans) with different target levels.
Target ramp through 2035
Targets reference EU fleet averages indexed to manufacturer-specific mass curves. The headline figures below are the EU-wide reduction targets that anchor each manufacturer's allocation.
| Year | Reduction vs 2021 | Fleet target (g CO2/km, WLTP) | Notes |
|---|---|---|---|
| 2021 | baseline | 115.1 | NEDC-WLTP transition; final NEDC year |
| 2025 | -15% | 93.6 | First step ramp |
| 2030 | -55% | 49.5 | Fit-for-55 revision (2023) |
| 2035 | -100% | 0 | Tailpipe zero for new cars (review 2026) |

Fleet exposure — worked example
The penalty arithmetic is linear and unforgiving. The table below shows the cost of overshooting fleet targets by 1, 2, and 3 g CO2/km at three illustrative annual EU registration volumes.
| Annual EU registrations | +1 g/km overshoot | +2 g/km overshoot | +3 g/km overshoot |
|---|---|---|---|
| 200,000 vehicles | 19.0 M EUR | 38.0 M EUR | 57.0 M EUR |
| 800,000 vehicles | 76.0 M EUR | 152.0 M EUR | 228.0 M EUR |
| 1,500,000 vehicles | 142.5 M EUR | 285.0 M EUR | 427.5 M EUR |
Formula: overshoot (g/km) × 95 EUR × registered vehicles. No threshold below which penalty does not apply.
The eco-innovation credit pathway
Articles 11 and 12 of Regulation (EU) 2019/631 establish a parallel mechanism: technologies whose CO2 benefit is not measured by WLTP can be granted approved eco-innovation status. Approval converts the verified benefit into a g CO2/km credit subtracted from the manufacturer's fleet average. The combined credit per manufacturer per year is capped at 7 g CO2/km.
The approval path:
- Manufacturer (or supplier with manufacturer support) submits a methodology to the Commission per Implementing Regulation (EU) 2014/725.
- An independent verifier validates the test protocol.
- Commission issues an Implementing Decision listing the technology, methodology, and CO2 benefit formula.
- Manufacturer applies the credit at type approval, with verifier sign-off per vehicle platform.
Glazing eco-innovation — the credit category and scale
Air-conditioning load reduction via solar heat control glazing is an established eco-innovation category. The mechanism: rejecting near-infrared (NIR) solar radiation reduces cabin heat-up, reduces compressor duty cycle, reduces fuel (ICE) or battery (BEV) energy spend on cooling.
Solar heat control via ATO (antimony-doped tin oxide) glazing — a wet-coatable transparent NIR absorber — has demonstrated:
- 9 degrees Celsius interior temperature reduction at peak solar load
- 35% AC power reduction at equivalent comfort setpoint
- 5G, RF, and LiDAR signal transparency (oxide, not metal)
- Haze below 0.3% after lamination (automotive optical grade)
For the credit pathway, the per-vehicle CO2 benefit depends on platform (ICE vs BEV), glazing surface area, and solar zone assumptions. For technology and methodology references, see Calculation Model 887.

The avoided-penalty calculation
A 1 g CO2/km eco-innovation credit, applied to a manufacturer registering 800,000 EU passenger cars per year, removes 76 million EUR of marginal penalty exposure annually — assuming the manufacturer would otherwise be 1 g/km over target. The credit operates linearly across the fleet target structure, so the same credit value applies in 2025 (target 93.6), 2030 (49.5), and through to 2034.
For platforms running close to the line, 0.5 to 1.0 g CO2/km of approved eco-innovation credit can be the difference between a clean year and a nine-figure premium.
For BEV platforms — range as the parallel benefit
Battery electric vehicles inherit the same eco-innovation framework (an AC-load reduction translates to less battery energy spent on cooling, which the methodology converts via grid CO2 intensity). But the engineering signal is sharper for BEVs: AC consumption is one of the largest non-traction loads. Reducing it extends range under hot-climate conditions by a measurable margin — Kriya has measured up to 16 km of range extension on representative BEV platforms with solar-heat-control glazing.

Frequently asked questions
What is the EU CO2 fleet penalty in practical terms?
Under Regulation (EU) 2019/631, every manufacturer pays 95 EUR per g CO2/km above its specific fleet target — multiplied by every passenger car registered in the EU that calendar year. A 1 g/km overshoot across 800,000 vehicles equals 76 million EUR per year. Targets ramp down in 2025, 2030, and 2035 (zero tailpipe CO2 for new cars). Penalties are paid as an excess emissions premium to the EU general budget; they are not deductible.
What is an eco-innovation credit?
Articles 11 and 12 of Regulation (EU) 2019/631 allow manufacturers to claim CO2 reductions from technologies whose benefit is not measured in the WLTP type-approval cycle. Approved eco-innovations are converted into a g CO2/km credit subtracted from the manufacturer's fleet average. The total credit ceiling per manufacturer is 7 g CO2/km (raised from 7 g/km under the 2009 regulation; cap clarification: combined eco-innovation credit cannot exceed 7 g CO2/km per manufacturer per year).
Why does solar heat control glazing qualify?
Solar heat rejection reduces cabin temperature, which reduces air-conditioning load, which reduces fuel or battery energy demand. The reduction is not captured in WLTP because WLTP runs at controlled lab temperature without solar load. Air-conditioning efficiency improvements are an established eco-innovation category — Commission Implementing Decisions have approved several glazing and AC-efficiency technologies in the 0.5 to 1.0 g CO2/km range per vehicle.
How is a glazing CO2 saving calculated for the credit application?
The methodology follows the structure laid down in Commission Implementing Regulation (EU) 2014/725 (and its successors): baseline AC energy demand under reference solar load is established, treated-glazing AC demand is measured under the same conditions, and the delta is converted to g CO2/km using vehicle-specific fuel-to-CO2 conversion factors. For BEVs, the energy delta is converted via grid CO2 intensity assumptions. Kriya provides this calculation per OEM platform via the Calculation Model 887 referenced below.
What about the 2035 zero-emission target — does the credit still matter?
Yes for two reasons. First, the 2025 target (93.6 g CO2/km fleet average) and the 2030 target (49.5 g CO2/km, a 55% reduction from 2021) apply to a decade of vehicle production where penalty exposure is real. Second, for BEVs the same energy delta translates to range — solar heat control reduces AC draw and extends range, which is itself a competitive parameter, not just a regulatory one.
