European working group launches report on monitoring use of CO2 neutral fuels

In Belgium, the Working Group on Monitoring Methodologies (WGMM) officially handed over its key report on “Monitoring the use of CO2 neutral fuels in road transport – a cross-sectoral industry assessment” to the European Commission. This report presents and analyses 11 potential technological options for the exclusive use of CO2 neutral fuels (CNFs) in new road vehicles, and proposes innovative solutions to ensure a sustainable tracking and verification of fuels in such vehicles. During the revision of the CO₂ emission standards for new cars and vans, European legislators decided a de-facto ban of internal combustion engines from 2035 by setting a 100% CO₂ reduction fleet average target measured at tailpipe. For trucks and buses, they decided on a 90% CO₂ reduction fleet average target measured at tailpipe from 2040, allowing scope for other measures, such as use of hydrogen and CNFs. Since its formation in September 2023 in Stuttgart, the WGMM identified and assessed different monitoring methodologies able to demonstrate the use of CNFs in new vehicles. Comprising more than 50 experts from the fuel and automotive industries, trade associations and researchers, the WGMM acts as a driving force for collaboration. The group aims to provide pragmatic and inclusive recommendations, considering the technical and economic realities of the fuel value chain and aligned with European climate objectives. The report proposes a new definition for CNFs which covers all renewable fuels, including eFuels and biofuels, compliant with the sustainability criteria set in the Renewable Energy Directive (RED). It includes 11 potential technological options, such as digital tracking systems, chemical marking with physical identification of CNFs throughout the supply chain, on-board vehicle detection and physical security of fuel connections as well as mass balancing
