As Europe accelerates its transition toward climate-neutral energy systems, biomass continues to play an important role within the renewable energy mix. In recent years, however, the discussion surrounding biomass has evolved significantly. Rather than focusing solely on its potential as a renewable energy source, policymakers and researchers increasingly emphasize the conditions under which biomass can be produced and used sustainably. Ensuring that bioenergy contributes to climate mitigation while preserving ecosystems and agricultural productivity has therefore become a central topic in European energy and environmental policy.
This issue is particularly relevant in rural areas, where agricultural and forestry residues represent a significant and locally available resource. These materials—including straw, pruning residues, forestry by-products, and organic agricultural waste—can be converted into heat, electricity, or biofuels. At the same time, these residues play an important ecological role within agricultural systems. Maintaining soil fertility, preventing erosion, and preserving biodiversity often requires that part of the biomass remains on the field. As a result, the sustainable use of biomass requires a careful balance between energy production and environmental protection.
Within the European Union, this balance is addressed through a regulatory framework established under the Renewable Energy Directive. The directive defines sustainability and greenhouse-gas-saving criteria for biomass used in energy production. According to these rules, bioenergy must provide substantial greenhouse gas emission reductions compared to fossil fuels and must not originate from areas characterized by high biodiversity or high carbon stock, such as primary forests or protected ecosystems. Furthermore, agricultural and forestry biomass must be produced in accordance with environmental standards related to soil protection, water management, and responsible land use. These requirements aim to ensure that expanding bioenergy production does not lead to unintended environmental consequences or the degradation of natural resources.
Another key direction within European bioenergy policy is the increased emphasis on residue-based biomass rather than dedicated energy crops. The use of agricultural and forestry residues allows energy to be generated from materials that are already produced as part of existing production systems, thereby reducing potential competition with food production. Nevertheless, scientific research highlights that the removal of residues from agricultural fields must be carefully managed. Excessive extraction can negatively affect soil organic matter, nutrient cycles, and long-term soil productivity. For this reason, regional biomass assessments are increasingly recommended to determine the amount of biomass that can be sustainably mobilized while maintaining ecological stability.
At the same time, discussions about biomass increasingly highlight the importance of decentralized and locally integrated energy systems. Instead of relying solely on large-scale bioenergy plants that require the long-distance transport of biomass feedstock, many experts advocate smaller systems that utilize locally available resources. Such approaches can strengthen energy resilience in rural communities, reduce transport-related emissions, and create additional economic opportunities for farmers and rural enterprises. Within this framework, biomass becomes part of a broader circular bioeconomy model in which biological resources are used efficiently for energy, materials, and other value-added products.
These topics and practical considerations are explored in greater detail in the SUSRUD project practical guide, developed to support rural stakeholders, educators, and local communities in understanding the sustainable use of biomass for energy. The guide provides an overview of relevant policy frameworks, sustainability principles, and examples of biomass applications in rural environments. Readers interested in exploring the topic further can access the full manual directly on the project website.
As Europe continues its transition toward climate neutrality, the role of biomass will depend not only on technological innovation but also on the ability to manage biological resources responsibly. By combining policy frameworks, scientific knowledge, and local cooperation, rural regions can harness biomass as part of a sustainable energy future while safeguarding the ecosystems and agricultural systems on which they depend.
