The Biofuel Demand SurgeDemand for biofuels is likely to leap by nearly a third this year as countries seek alternatives to expensive oil. The US, Indonesia, Brazil, Thailand and others have opted to increase biofuel use as the price of oil has jumped to nearly $100 a barrel after the US-Israeli attacks on Iran and the closure of the strait of Hormuz.Projected Growth and Environmental ConcernsIf oil supplies remain constrained, demand for biofuels could increase by 70% by 2030, according to estimates from the Transport & Environment (T&E;) thinktank. Biofuels, from oil-bearing crops and grains, currently supply about 4% of the world's transport energy demand. Expanding biofuel production without competing with food crops for land and fertiliser would be difficult to achieve, and reaching 20% of global road fuel from biofuels would require an area the size of South Africa.The Food Security ImpactThe expansion of biofuels comes at a time when fertilizer supply has been constrained by the war and prices have soared, leading to rises in the price of staple foods for some of the poorest people in many parts of the world. Biofuels compete with food crops for land, while globally about one in every 20 tonnes of fertiliser is used to produce crops for fuel. In some countries it is a lot more: a tenth of fertiliser use in the US is for biofuels, and a fifth in Indonesia.Historical Precedents and Future ProjectionsThough it is not possible to say exactly how far the expansion of biofuels could lift food prices, experts suggest it could be significant. In the food crises of 2007-08, the UN's Food and Agriculture Organization estimated that biofuel use contributed between 40% and 70% of the increase in maize and soya bean prices. The US is already forecasting that food prices will rise this year by between 2.2% and 4.7%, largely owing to the impacts of the war in Iran.Sustainable AlternativesEncouraging the switch to electric vehicles could reduce demand for biofuels, as generating renewable energy is a far more efficient use of land than growing crops for fuel. Solar panels covering just 3% of the land currently used for biofuel production would generate the same amount of energy, and because of the higher efficiency of electric vehicles, that would be enough to power a third of the global car fleet.

Europe’s rail infrastructure is physically capable of moving millions of passengers, but its digital booking systems remain stuck in a 'stone age,' severely limiting the ability of travelers to choose greener alternatives to flying. A comprehensive analysis by the Transport & Environment (T&E;) thinktank has found that booking equivalent train tickets is 'difficult or impossible' on nearly half of the EU’s busiest international air routes.Key DevelopmentsThe study examined the 30 busiest international air routes within the EU, excluding island trips and routes longer than 1,500km. The findings highlight a fragmented market where passengers face significant friction when attempting to switch from air to rail. Notably, popular flight paths such as Lisbon-Madrid and Barcelona-Milan were found to be unbookable from any rail operator’s website. Similarly, routes like Paris-Rome and Amsterdam-Milan could only be booked from a single operator, forcing travelers to navigate multiple websites or third-party aggregators.Data & Market ImpactThe report exposes a systemic failure in cross-border connectivity. Passengers could not purchase tickets covering the entire journey on 20% of the analyzed routes. Additionally, tickets were available from only one operator on a further 27% of routes, bringing the total to 47% where booking is 'hard or impossible.'Market Monopoly: Incumbent operators like Deutsche Bahn and SNCF do not sell competitors' tickets on 86% of routes where competition exists.Visibility Gap: On 59% of these routes, alternative services are not even displayed to the consumer.Consumer Behavior: A 61% of long-distance rail travelers have avoided journeys due to booking difficulties, with 40% stating they would travel more by rail if the process were easier.Why This MattersThis booking friction represents a critical barrier to the EU's climate targets. Aviation is one of the hardest sectors to decarbonize, and its emissions are projected to soar as the industry seeks to double passenger traffic by 2050. By making it structurally difficult for even climate-conscious travelers to choose rail, the current system effectively locks in high-carbon air travel. The inability to easily compare prices or book seamless multi-leg journeys means that despite trains often being a viable alternative, the 'intention-action gap' prevents the necessary shift in consumer behavior.Expert InsightGeorgia Whitaker, a rail campaigner at T&E;, described the situation as 'almost feels a bit silly,' noting that in a digital-first world, a clunky system is actively stifling climate action. Brian Caulfield, a transport researcher at Trinity College Dublin, emphasized that the problem is not just technical but structural. He argued that major operators are failing to display or sell cross-border connections, creating a market environment that makes it difficult for even the most environmentally aware consumers to make the 'greener option' a reality.What Happens NextThe European Commission is set to publish a single ticketing package on 13 May, a regulatory move designed to allow Europeans to travel across the continent more easily and enjoy standard consumer protections. However, the report suggests that without strict enforcement of interoperability standards, the current fragmentation will persist. The upcoming regulations will be a critical test of whether the EU can modernize its rail infrastructure to compete with the convenience of aviation in the race to meet 2050 climate goals.
