amending Commission Regulation (EU) 2017/1151 as regards the emission type 
approval procedures for light passenger and commercial vehicles running exclusively on

(Text with EEA relevance)  
THE EUROPEAN COMMISSION,  
Having regard to the Treaty on the Functioning of the European Union, 
Having regard to Regulation (EC) No 715/2007 of the European Parliament and of the 
Council of 20 June 2007 on type approval of motor vehicles with respect to emissions from light passenger and commercial vehicles (Euro 5 and Euro 6) and on access to vehicle repair 
and maintenance information1, and in particular Articles 5(3) and 14(3) thereof, 
Whereas:  
(1) Regulation (EC) No 715/2007 regulates type approval of motor vehicles with regard to 
their emissions. To that end, it requires new light passenger and commercial vehicles to comply with certain emission limits. The specific technical provisions n ecessary to 
implement that Regulation are set out in Commission Regulation (EU) 2017/1151
2. 
(2) CO 2 neutral  fuels are renewable liquid and gaseous fuels  of non- biological origin as 
defined in Directive (EU) 2018/20013 which  achieve greenhouse gas emissions 
savings of at least 100% in accordance with the methodology established under that 
Directive . 
(3) Vehicles  running exclusively on CO 2 neutral fuels  when using an internal combustion 
engine are vehicles designed and constructed  in such a way so that they cannot run on 
any other types of fuels  in combustion mode .  If the internal combustion engine is 
fuelled with fuels  other than CO 2 neutral fuels , such vehicles should be able to detect it 
and prevent  the vehicle from starting until it is fuelled with CO 2 neutral fuel. The 
choice of technological solutions for such fuelling monitors and fuelling inducement systems should be up to the manufacturers. 
(4) Currently , anti- tampering rules are limited in scope to emission controls and the 
odometer. Theref ore, specific anti -tampering rules for fuelling monitors and fuelling 
inducement systems are needed .

2 Commission Regulation (EU) 2017/1151  of 1  June 2017 supplementing Regulation (EC) No  715/2007 
of the European Parliament and of the Council on type -approval of motor vehicles with respect to 
emissions from light passenger and commercial vehicles (Euro 5 and Euro 6) and on access to vehicle 
repair and maintenance information, amending Directive 2007/46/EC of the European Parliament and 
of the Council, Commission Regulation (EC) No  692/2008 and Commission Regulation (EU) 
No  1230/2012 and repealing Regulation (EC) No  692/2008  (OJ L 175, 7.7.2017, p.  1). 
3 Directive (EU) 2018/2001 of the European Parliament and of the Council of 11 December 2018 on the 
promotion of the use of energy from renewable sources (OJ L 328, 21.12.2018, p.  82). EN 2  EN (5) To allow the type approval of vehicles running exclusively on CO 2 neutral  fuels, the 
test procedures, administrative provisions , information documents , type approval 
certificates  and the certificate of conformity need to be adapted.  
(6) To align the Worldwide Harmonised Light -duty Vehicles  Test Procedure (WLTP) 
methodology laid dow n in Regulation (EU) 2017/1151 with UN Regulation No 1544, 
it should be made clear that when a vehicle is running on hydrogen, there is no need to 
measure CO 2 emissions.  
(7) It should be clarified that for the evaporative emissions test and on- board diagnost ics 
systems, the specific conformity of production requirements of UN Regulation No 154 
apply.  
(8) It should also be clarified that for the power measurement of electric drive trains both 
the net power and the maximum 30 minutes power should be determined.  
(9) It is therefore necessary to amend Regulation (EU) 2017/1151 and Commission 
Implementing Regulation (EU) 2020/683.  
(10) The measures provided for in this Regulation are in accordance with the opinion of the Technical Committee  – Motor Vehicles,

2 neutral fuels ’ mean renewable fuels of non -biological origin as 
defined in Directive (EU) 2018/2001, that  achieve the minimum threshold for 
greenhouse gas emissions savings of at least 100 %, calculated  in accordance 
with Commission Delegated  Regulation (EU) 2023/1184 and Commission 
Delegated  Regulation (EU) 2023/1185.  
(9b) ‘vehicle running exclusively on CO 2 neutral fuels ’ means a vehicle that is

fuels and  which  cannot run on with other types of fue ls when using an internal 
combustion engine ; 
(9c) ‘fuell ing monitor’ is a device that checks whether a vehicle running

(9d) ‘fuelling induc ement system’ is a system that prevents a vehicle running 
exclusively on CO 2 neutral fuels from starting if fuelled with  fuels  other than
