The European Commission expects the use of biomass for energy in the EU to increase significantly between 2010 and 2020 to meet a legally binding target to cover at least 20% of EU's total energy use from renewable sources in 2020. According to estimates made by the member states of the EU, the direct supply of biomass from forests is expected to increase by 45% on a volume basis between 2006 and 2020 in response to increasing demand (Beurskens LWM, Hekkenberg M, Vethman P.

Proceedings of the 18th EBCE, 1575-1579 ; Forest biomass is an important source of bioenergy and its importance is growing even more in the near future. The European Union has given targets for the use of bioenergy and national climate and energy programmes set more detailed, country-specific targets. It is often argued that using biomass in energy production will reduce greenhouse gases along the product's value chain. This argument is based on the fact that biomass is renewable and the carbon dioxide that is emitted during the combustion is absorbed again by the biomass growth. Because time is a relevant factor when studying carbon balances, two time scopes were studied in this paper: 50 years and 100 years. This paper concentrates on collecting spruce harvesting residues after final felling in Southern-Finland. The forest carbon balance is linked to the residue extraction module and further to residue combustion. The emissions from forest residue extraction originate from soil carbon stock change and collecting, transporting and chipping of forest residues. In this paper, the soil carbon stock change caused by residue collection is considered as an emission since soil carbon stock decreases when residues are collected. The results show that if changes in soil carbon balance were excluded and an emission factor for forest residues included only fossil emissions from collection and transporting the residues, a significant amount of emissions would be neglected from the calculations. ; 18th European Biomass Conference and Exhibition, 3-7 May 2010, Lyon, France

In July 2016, the European Commission (EC) published a legislative proposal for incorporating greenhouse gas emissions and removals due to Land Use, Land Use Change and Forestry (LULUCF) into its 2030 Climate and Energy Framework. The Climate and Energy Framework aims at a total emission reduction of 40% by 2030 for all sectors together as part of the Paris Agreement. The LULUCF proposal regulates a "no debit" target for LULUCF (Forests and Agricultural soils), and regulates the accounting of any additional mitigation potential that might be expected of it. We find that the forest share of the LULUCF sector can achieve much more than what is in the regulation now. We elaborate a strategy for unlocking European Union (EU) forests and forest sector potential based on the concept of "climate smart forestry" (CSF). We find that to-date, European policy has not firmly integrated forest potential into the EU climate policy framework. Nor have climate objectives been firmly integrated into those of the forest and forest sector at either the EU or national level. Yet a wide range of measures can be applied to provide positive incentives for more firmly integrating these climate objectives into the forest and forest sector framework. With the right set of incentives in place at EU and Member States levels, we find the current literature supports the view that the EU has the potential to achieve an additional combined mitigation impact through CSF of 441 Mt CO2/year by 2050. In addition, CSF, through reducing and/or removing greenhouse gas emissions, adapting and building forest resilience, and sustainably increasing forest productivity and incomes, tackles multiple policy goals.

There is growing concern that the implementation of political agreements on climate change and biodiversity will not be enough to protect forests in the short run and up to the end of the 21st century. As mitigation efforts are lagging behind self-imposed, reasonable targets, genetic diversity will have a large and significant part to play in the process of adapting forests to climate change. Genetic diversity, the raw material of evolution, can be used for adaptation by natural selection and artificial breeding, in naturally regenerated and plantation forests alike. The two-day scientific conference: "#rescueforests: Genetics to the rescue - Managing forests sustainably in a changing world", addressed the genetic diversity of forests. More specifically, the conference was about natural as well as assisted adaptive processes, their spatial scale, from fine grain to landscape and ecoregions, and how much of the genome it involves. It also dealt with phenotypes and how much of their variation is determined by underlying genetic diversity. And finally, and perhaps most importantly, the conference emphasized the importance of conservation and sustainable use of this genetic diversity as a nature-based solution to adapt under the fast pace of climate change. The conference demonstrated how improved knowledge on genomic diversity and evolutionary mechanisms can help to rescue forests, either naturally or by means of management.

This report demonstrates the application of recreational scores, obtained through a pan-European Delphi survey as part of EFORWOOD, to model the impacts of changes in forest management on the recreational value of European forests. Changes in the level of implementation of the Natura 2000 policy is used as an example. Currently, about 8% of the EU forest area is allocated to biodiversity conservation (MCPFE class 1; MCPFE 2007). According to the Natura 2000 Agenda, 15% of the territory of the EU should be designated as conservation area by 2025. It is to be expected, therefore, that the forest conservation area will increase considerably in the near future. The impact of different nature conservation implementation levels on the recreational value of forests in Europe was explored using recreational scores derived from the Delphi survey, and combined with outputs from the forest scenario model EFISCEN. Changes in recreational value were considered against two background futures (A1 and B2 from the SRES scenarios) and three different nature conservation implementation levels. The results suggest that overall an increase in forest area managed for conservation would cause a slight net increase the recreational value per hectare of forests in Europe, although there is considerable variation between countries.
