CO2 targets: why did the European Commission give carmakers three years?
In early March 2025, the European Commission announced greater flexibility in the way CO2 reduction targets would apply to European car manufacturers.
Instead of assessing compliance against the 2025 objective over a single year, manufacturers would be given three years over which to meet the targets.
The decision brought relief to an automotive industry facing the prospect of fines worth several billion euros.
Environmental organisations, however, criticised the move.
At the heart of the debate was a simple market equation:
to meet the original trajectory, fully electric vehicles would effectively have needed to represent around 25% of new-car sales in 2025.
Why was the gap between that figure and actual demand so large? Was the target achievable? And what did the decision signal about the future of Europe’s automotive transition?
Key figures
Key takeaways:
– European Commission decision announced in early March 2025
– a three-year compliance period rather than assessment solely against 2025
– implied electric vehicle share required to meet the target: around 25% of sales
– potential fines for manufacturers: several billion euros
– European new-car volumes remain below their 2019 level
A target that market demand was not yet reaching
The gap between the regulatory trajectory and actual market conditions was not simply a short-term fluctuation.
Reaching an electric share of around 25% in 2025 would have required a sharp acceleration in adoption.
But actual demand remained significantly lower.
Battery-electric vehicles accounted for around 15% of sales during 2025 at the time of the initial debate, eventually reaching 17.4% across the full year in Europe.
In other words, the trajectory required adoption to accelerate very rapidly while several of the main barriers to purchase remained:
– price
– charging access
– range concerns
– uncertainty over resale value
This highlights a broader methodological issue.
A regulation targeting the composition of sales depends not only on what manufacturers produce but also on what consumers are willing and able to buy.
A carmaker can bring more electric vehicles to market.
It cannot directly force households to choose them.
An automotive industry already under pressure
The wider market context was crucial.
European new-car volumes had still not returned to their 2019 level.
The pandemic did not simply create a temporary fall followed by a full recovery.
Instead, the market settled at a lower level.
At the same time, manufacturers continued to face massive transition costs:
– electrifying vehicle ranges
– battery investment
– manufacturing transformation
– distribution networks
– after-sales and servicing infrastructure
Potential penalties worth several billion euros would therefore have been added to an industry already investing heavily while operating at reduced market volumes.
This combination explains why manufacturers welcomed the Commission’s decision.
The environmental argument and the real point of disagreement
Environmental organisations strongly criticised the greater flexibility.
Their argument is straightforward:
Delaying the effect of a target delays part of the incentive created by that target.
If regulatory pressure is reduced in the short term, manufacturers may face less immediate pressure to increase electric vehicle sales, potentially slowing reductions in CO2 emissions.
The underlying disagreement is therefore about how demand responds to regulation.
The case for strict targets
Supporters of strict regulation argue that pressure on manufacturers changes the market.
It forces companies to increase supply, reduce prices and invest faster, which can ultimately accelerate consumer adoption.
The case for greater flexibility
Supporters of the adjustment argue that regulation calibrated too far above effective consumer demand does not automatically produce more EV sales.
Instead, it may simply generate penalties for manufacturers when households are not yet ready to buy electric vehicles at the required rate.
The two positions therefore depend on different assumptions about the price and behavioural elasticity of EV demand.
The debate remains open.
What the March 2025 decision foreshadowed
With hindsight, the March decision can be seen as an early signal of a broader debate over Europe’s automotive transition timetable.
| Date | Decision or development |
|---|---|
| March 2025 | CO2 compliance rules eased through a three-year assessment period |
| October 2025 | The 2035 combustion-engine phase-out itself faces growing political opposition |
| Full-year 2025 | Battery-electric cars reach 17.4% of European sales, still below the earlier 25% benchmark |
The March adjustment was therefore not necessarily an isolated technical change.
It became part of a wider discussion about how quickly Europe’s automotive transition could realistically proceed.
FAQ – EU automotive CO2 rules
Why did the European Commission ease the CO2 rules for carmakers?
Because meeting the original 2025 trajectory would have required
electric vehicles to account for around 25% of sales, well above the
level of demand observed at the time. Manufacturers also faced potential
fines worth several billion euros.
What target were car manufacturers expected to meet?
The 2025 CO2 reduction objective effectively required electric vehicles
to represent around 25% of new-car sales. The Commission subsequently
allowed compliance to be assessed over a three-year period.
Why was the target difficult to reach?
Sales targets depend on consumer behaviour as well as manufacturer
supply. Factors such as price, charging access, range and resale-value
uncertainty continued to limit electric vehicle demand.
Why did environmental organisations oppose the decision?
They argued that easing the short-term constraint could weaken incentives
to increase electric vehicle sales and potentially slow reductions in
CO2 emissions.
What was the economic context for European carmakers?
European new-car sales remained below their 2019 level while
manufacturers were making major investments in electrification,
batteries, production and distribution.

Key takeaways
In early March 2025, the European Commission gave car manufacturers three years over which to meet CO2 reduction targets that had originally been assessed against 2025.
The initial trajectory effectively required electric vehicles to represent around 25% of sales.
Actual demand remained significantly lower, at around 15% during part of 2025 and 17.4% across the full year.
Without greater flexibility, manufacturers faced potential fines worth several billion euros while European new-car volumes were still below their 2019 level and transition investment remained extremely high.
Environmental organisations criticised the decision, arguing that weaker short-term pressure could slow emissions reductions.
With hindsight, the March decision also became an early sign of a broader European debate over the pace, credibility and economic feasibility of the automotive transition.
