Can greener roads be truly sustainable? Bio-asphalt, forest limits and the boundaries of the bioeconomy Can greener roads be truly sustainable? Bio-asphalt, forest limits and the boundaries of the bioeconomy

Europe is electrifying its vehicles while the roads beneath them remain almost entirely fossil-dependent. A pilot scheme in northern Spain shows that bio-based binders can cut bitumen's carbon footprint by up to 75%. But can Europe source these materials without depleting the ecosystems that supply them? "In the bioeconomy, the limit is the forest," warns Martin Pigeon of Fern.

Solar guardrails: Turning thousands of roads into energy sources Solar guardrails: Turning thousands of roads into energy sources

The world’s first photovoltaic guardrail might turn roads and highways into energy sources. Developed to enhance sustainability, this groundbreaking innovation could help decarbonize Europe’s transport infrastructure. Yet, experts warn: “For such solutions to become reality, we need more opportunities to implement our innovative approaches.
