(NGV Journal/European Biogas Association) Members of European Parliament (MEPs) from different political groups have signed a petition asking the European Commission to remove barriers to the deployment of sustainable fuels and technologies in transport by reviewing the current tailpipe approach to measure CO2 emissions. This will ensure the swift decarbonisation of the transport sector. The development of clean mobility will be essential to reach climate-neutrality. The sector needs to reduce its emissions by 90% in 2050, while ensuring that the EU transport industry remains competitive and the transition to clean technologies leaves no one behind. The EU needs cost-competitive fuels and technologies available right now to achieve this goal. Biomethane belongs to the most promising alternative fuels: it allows emissions reductions already in the short term and by 2030, and its production promotes the deployment of a circular bioeconomy. When well-to-wheel emissions are taken into account, biomethane is clearly among the least emitting transport fuels. This approach considers the whole production and use cycles of the vehicles, compared to the current standard, which measures only tailpipe emissions.
