Under current EU rules, all new cars registered from 2035 must produce zero carbon dioxide emissions. This move aims at accelerating the shift towards battery-electric vehicles and phasing out fossil fuels and conventional internal combustion engines. However, car manufacturers are lobbying for an exemption that would permit internal combustion engines to run on what they describe as ‘carbon-neutral’ biofuels.

T&E’s latest report highlights changes made in 2018 which curbed the use of crop-based biofuels derived from feedstocks like palm oil and soy. These reforms prioritized waste-based inputs such as used cooking oil and animal fats, now accounting for around half of bio-based diesel used within the EU.

Despite these changes, T&E points out that roughly 60% of all biofuels and 80% of used cooking oil in the EU are imported from outside the region, predominantly from Asian markets. This reliance on foreign sources raises concerns about sustainability and carbon neutrality.

The European Commission is expected to present a package of measures for the automotive sector on December 10th, which could include decisions regarding biofuels beyond 2035. As electric vehicles become more prevalent and affordable, the debate around biofuels highlights the complex challenges in transitioning to cleaner transportation.

As Europe moves towards a greener future with electric vehicles, the debate over biofuels highlights the complexities in balancing economic interests with environmental goals. The upcoming EU measures will be crucial in shaping the automotive landscape beyond 2035.

However, the journey of biofuels in the United States since 2005 hasn’t been without controversy. The federal Energy Policy Act mandated blending ethanol with gasoline to lower exhaust emissions, but many saw this move as a subsidy for corn farmers rather than an environmental initiative. Today, similar debates are echoing across global forums about whether biofuels truly represent a sustainable solution.

Brazil’s reliance on ethanol has been a model for other nations, yet it raises questions about the broader impact of scaling up biofuel production. The process demands vast amounts of cropland, leading to deforestation and the conversion of grasslands into farmland. This not only disrupts ecosystems but also contributes to increased carbon dioxide levels.

Research from Transport and Environment reveals that biofuels may actually produce 16% more CO2 compared to fossil fuels they replace. Moreover, the land used for growing crops for biofuel could instead feed up to 1.2 billion people or generate significant solar power if converted into solar farms. These findings challenge the viability of large-scale biofuel production.

As countries like Brazil continue to promote their success stories with biofuels, critics argue that such approaches may not be universally applicable due to varying land availability and agricultural practices around the world. The environmental costs associated with expanding cropland for biofuels could outweigh any benefits in terms of reducing carbon emissions.

So, are biofuels a promising step towards cleaner transportation or just another form of greenwashing? As discussions at COP30 show, there’s no easy answer. While some see potential in the rapid expansion of sustainable fuels, others warn about the risks and drawbacks inherent to large-scale production. The debate is far from settled, but it’s clear that finding a balance between environmental goals and practical realities will be crucial.
