Abstract
Background and Purpose: Solid biomass from short rotation coppice (SRC) has the potential to significantly contribute to European renewable energy targets and the expected demand for wood for energy, driven mainly by market forces and supported by the targets of national and European energy policies. It is expected that in the near future the number of hectares under SRC will increase in Europe. Besides producing biomass for energy, SRC cultivation can result in various benefits for the environment if it is conducted in a sustainable way. This paper provides with an overview of these environmental benefits. Discussion and Conclusions: The review of existing literature shows that SRC helps to improve water quality, enhance biodiversity, prevent erosion, reduce chemical inputs (fertilizers, pesticides) and mitigate climate change due to carbon storage. To promote and disseminate environmentally sustainable production of SRC, based on existing literature and own project experience, a set of sustainability recommendations for SRC production is developed. In addition to numerous environmental benefits, sustainable SRC supply chains can bring also economic and social benefits. However, these aspects of sustainability are not addressed in this paper since they are often country specific and often rely on local conditions and policies. The sustainable practices identified in this manuscript should be promoted among relevant stakeholder to stimulate sustainable local SRC production.

Biomass plays a key role among renewable energy sources in Europe, accounting for almost 70 % of all renewables, and showing steady growth
Solid biomass from short rotation coppice (SRC) has been identified with high potential to significantly contribute to European renewable energy targets [2]
The term SRC refers to biomass productions systems cultivated for energy purposes using fast-growing tree species with the ability to resprout from the stumps after harvest
Summary
Biomass plays a key role among renewable energy sources in Europe, accounting for almost 70 % of all renewables, and showing steady growth. As SRC species, willows and poplars have been predominantly used in Europe, since they are fast-growing with good coppice ability that reach high growth rates even under very short harvest intervals. Other tree species such as black locust and eucalyptus have been considered for larger implementation as SRC systems for energy. SRF uses fast-growing tree species and having denser spacing and more intensive management than traditional forestry, and trees are typically harvested after 2 to 25 years depending on the desired end-product In this context SRC represents a more specialised and intense practice of SRF dedicated mainly for energy purposes. This paper provides with an overview of these environmental benefits
