Global bioethanol production is growing steadily and is expected to continue. This growth is due to the great advantages it offers in many aspects and that makes it sustainable. Among the environmental advantages, the drastic reduction of GHG emissions with respect to the gasoline it replaces, the lower emissions of other gases and polluting particles, the improvement of vehicle efficiency and the consequent reduction in the demand for oil with the advantageous consequences that they imply.
Another important environmental advantage is that it does not require the development of new distribution infrastructure or vehicles, so the impact of its implementation is minimized. This is comparatively very different from other mobility options to come, such as electric vehicles, in which both vehicles and charging infrastructures are new and especially intensive in the emission of GHG.
Given that the production of bioethanol is based on sustainable agricultural crops, the support to these sustainable crops is leading to the development of rural communities, avoiding the adverse effects that depopulation of these regions can entail at the environmental level.
The responsible use of the land is compatible and is favored by the cultivation of raw materials for biofuels, since the crops used in the European Union for the production of bioethanol meet the strictest environmental sustainability standards in the world. In this sense, production facilities must certify GHG emission reductions against the use of 50-60% gasoline based on their characteristics. In fact, the average reduction of European producers is approximately 71% in GHG emissions compared to gasoline.
Sustainability is present in the entire production value chain. The impact on human food is null, given the surpluses that occur each year from raw materials and the conversion of land use is minimal. In Europe there are abandoned or cultivated lands with very low productivity that could be dedicated to the production of raw material for bioethanol. Increases in crop yield are also expected that will limit the needs of new crops and improve the sustainability of the process.
Moreover, given that one of the co-products obtained in bioethanol production is animal feed, the existence of this co-product limits imports and the cultivation of soybeans, in areas outside the European Union where there is a greater need for crops for human food.
There are other aspects related to sustainability, such as the improvement of energy security and animal nutrition, to which local bioethanol production helps significantly, reducing both oil and oil imports.
For all these reasons, bioethanol plays a fundamental role in the decarbonization of the planet, and they are presented as one of the most advantageous and economical alternatives for reducing transport emissions.
