Vehicles powered by e-fuel will emit virtually 5 occasions as a lot CO2 as electrical autos if the EU waters down plans to require them to be carbon impartial, a new evaluation finds. All new automobiles offered within the EU from 2035 should emit zero CO2 emissions on the tailpipe, however the bloc is about to make an exemption for automobiles operating on artificial gasoline. Whereas the EU Fee says solely e-fuels which might be 100% carbon impartial can qualify for the loophole, the oil trade needs that standards weakened.
Transport & Surroundings (T&E) calculated the ‘well-to-wheel’ CO2 emissions of e-fuels — the full emissions required to supply, distribute and use the gasoline.(1) The evaluation reveals that e-petrol automobiles would emit 61 grams of CO2 equal per km in 2035 if lawmakers apply the weaker 70% carbon impartial standards, which is required by the present EU renewable vitality legislation. This contrasts with electrical autos, which might solely emit 13 gCO2/km when charged with electrical energy from the typical EU grid from 2035. To be absolutely carbon impartial, e-fuels would have to be made utilizing captured CO2 emissions that stability out the carbon dioxide launched when the gasoline is burned in an engine.
Alex Keynes, automobiles coverage supervisor at T&E, stated: “The European Fee has stated e-fuels have to be carbon impartial to flee the ban on new polluting automobiles after 2035. For years the e-fuels foyer informed us how clear their fuels are, so it’s incomprehensible why they might not meet the standards as proposed. It’s as much as EU governments to face by the Fee’s carbon impartial requirement.”
Whereas artificial fuels can be carbon impartial beneath the Fee’s plan, they’ll nonetheless emit air pollution, notably poisonous NO2 and carcinogenic particles, when burned in combustion engines. T&E checks have proven that automobiles powered by e-fuel emit as a lot nitrogen oxides (NOx) as fossil gasoline engines (round 22 mg/km) and far more carbon monoxide and ammonia, doing nothing to alleviate the air high quality issues in our cities.
E-fuels are additionally costly to supply, and filling up automobiles on artificial petrol will value drivers excess of operating a battery electrical car or even a automotive on fossil petrol. Producing e-fuels can also be far much less environment friendly than powering electrical autos. Supplying only a small proportion of latest automobiles with e-fuels as a substitute of electrifying them would require considerably extra renewable electrical energy era in Europe.
The Fee has requested member states for suggestions on its proposal to permit solely 100% carbon impartial e-fuels in new automobiles after 2035. EU governments are anticipated to take a last resolution on the standards earlier than the tip of the yr.

Evaluation – E-fuel automobiles usually are not zero emission
In September 2023, the European Fee shared a draft textual content which outlined a brand new class of autos operating completely on artificial fuels (or e-fuels). The central level of debate is across the degree of greenhouse fuel (GHG) discount that these e-fuels ought to obtain. Presently, e-fuels solely want to satisfy a 70% GHG emissions discount threshold in comparison with fossil fuels, as per the EU’s Renewable Vitality Directive methodology (RED).
T&E evaluation reveals that e-petrol automobiles would emit 61 gCO2e/km in 2035 beneath the prevailing RED e-fuel system. This contrasts with EVs, which might solely emit 13 gCO2/km when charged with electrical energy from the EU common grid in 2035. Below such a system, e-petrol automobiles can be thought-about CO2 impartial however would nonetheless emit round 5 occasions extra CO2 emissions than equal EV fashions. Moreover, e-petrol automobiles emit air pollution, together with poisonous nitrogen oxides (NOx) and carcinogenic particles.
Briefly, for the EU to respect the official settlement and resolution of co-legislators, it’s not potential to permit e-fuels that don’t attain a 100% GHG discount when utilized in automobiles. Particularly a 70% discount would disregard the prevailing settlement to solely permit “autos operating completely on CO2 impartial fuels”.
E-fuels allowed in automobiles ought to adjust to a strict framework to certify and guarantee RFNBOs ship 100% CO2 discount. Such guidelines ought to be sure that all the electrical energy used within the course of (manufacturing of the e-fuel and DAC) is 100% generated from extra renewable vitality sources. The carbon used should even be from 100% direct air seize (DAC) to forestall any extra CO2 being launched into the ambiance. Any residual emissions from the transport and distribution of the e-fuel ought to be offset by carbon seize and storage (CCS) – as per the RED RFNBO methodology – to make sure achievement of 100% GHG emissions discount.
E-fuel automobiles shouldn’t be designated as zero-emission for the needs of regulatory compliance given they nonetheless emit poisonous air pollution. In any other case it will undermine efforts to scale back air pollution and set up low- and zero-emission zones in European cities.

(1) T&E’s evaluation relies on the next assumptions:
Typical petrol automotive: C-segment automotive offered in 2035 operating on typical petrol emitting 94 gCO2eq/MJ.
E-petrol automotive: Similar automotive operating on e-petrol with 70% CO2 discount in comparison with typical petrol in line with the RFNBO methodology of the EU Renewable Vitality Directive. The emission discount from the e-fuel ‘well-to-wheel’ emissions is achieved by carbon seize.
Electrical automotive: C-segment BEV, common carbon depth of the European grid.
