EU CO2 fleet targets: the regulatory ramp
Under Regulation (EU) 2019/631 and its amendments, the EU imposes binding fleet-average CO2 emission targets on every vehicle manufacturer. The targets are aggressive and the ramp is steep:
| Period | Target (g CO2/km) | Reduction vs 2021 |
|---|---|---|
| 2025 to 2029 | 93.6 | -15% |
| 2030 to 2034 | 49.5 | -55% |
| 2035 onwards | 0 | -100% |
The 2030 target of 49.5 g/km is particularly consequential. Few manufacturers currently achieve fleet averages below 80 g/km, meaning the gap to close is 30 g/km or more in the next few years. Every gram matters, and every technology that contributes even a fraction of a gram to fleet-average reduction has outsized financial value.
Penalty mechanics: 95 EUR per g/km per vehicle
The penalty is calculated per excess gram of CO2 per kilometre, multiplied by every vehicle registered in the EU that year. At 95 euros per g/km per vehicle, the mathematics are severe:
- A manufacturer registering 800,000 vehicles per year that exceeds the target by 1 g/km faces 76 million euros in penalties
- Exceeding by 11 g/km (a plausible 2025 scenario for some manufacturers) means approximately 836 million euros
- By 2030, with the target at 49.5 g/km, the same manufacturer exceeding by 30 g/km would face approximately 2.28 billion euros
These are not hypothetical numbers. They are the direct financial exposure that fleet CO2 management teams are working to mitigate today.
How solar heat control glazing reduces fleet-average CO2
Solar heat control glazing reduces the AC power needed to maintain cabin temperature. In the WLTP test cycle and in real-world conditions, lower AC power consumption translates to lower total vehicle energy consumption, which translates to lower CO2 emissions per kilometre for ICE and hybrid vehicles, and lower electricity consumption for EVs.
Using Kriya's ATO solar heat control (detailed on the solar heat control page), the measured AC power reduction is 35%. This reduction is available across the entire fleet — every vehicle with solar heat control glazing benefits — making it a scalable fleet-average tool rather than a niche solution.
Eco-innovation credit pathway
EU Regulation 2019/631 includes an eco-innovation mechanism that grants CO2 credits for technologies that reduce real-world emissions but are not fully captured in the standard WLTP test cycle. Solar heat control glazing — because its benefit depends on solar conditions not present in the test cycle — is a candidate for eco-innovation certification.
Key parameters:
- Available from 2025 onwards
- Up to 6 g CO2/km credit per manufacturer per year until 2029
- Requires certified testing methodology and type-approval documentation
- Applicable to both ICE/hybrid and BEV platforms
At 800,000 vehicles and 95 euros per g/km, a 6 g/km eco-innovation credit is worth up to 456 million euros in penalty avoidance. The certification cost is a fraction of this value.
Worked example: fleet exposure scenarios
The following scenarios illustrate the penalty exposure for a representative European manufacturer (approximately 800,000 EU registrations):
| Scenario | Fleet avg | Target | Gap | Exposure |
|---|---|---|---|---|
| 2025 | ~105 g/km | 93.6 g/km | ~11 g/km | ~836M EUR |
| 2030 | ~80 g/km | 49.5 g/km | ~30 g/km | ~2.28B EUR |
Rule of thumb: every 1 g/km fleet-average reduction over 800,000 vehicles avoids approximately 76 million euros in penalties.
Forward-looking: 2030 and beyond
The 2030 target of 49.5 g/km and the 2035 target of 0 g/km require a fundamental fleet transformation toward electrification. But even fully electric fleets benefit from solar heat control: lower AC power extends range, reduces battery requirements, and lowers total cost of ownership. The thermal management challenge does not disappear with electrification — it intensifies, because every watt matters more.
How to start: validation and certification
The path from material evaluation to fleet deployment follows a structured process:
- Material evaluation — Kriya provides ATO samples and technical support for glazing prototypes
- Vehicle-level testing — cabin temperature and AC power measurements on instrumented vehicles
- Eco-innovation application — supporting data for type-approval documentation
- Volume supply — contract manufacturing from Kriya's execution-ready plant
Kriya's team works directly with OEM fleet CO2 management, Tier-1 glazing suppliers, and regulatory affairs departments throughout this process.
