“…Forest resources in Latvia in the study are evaluated according to activity data and assumptions used in development of forest reference level; particularly, management assumptions (harvest intensity by species, forest regeneration and thinning probabilities) and forest area according to the reference period (2000)(2001)(2002)(2003)(2004)(2005)(2006)(2007)(2008)(2009) and projections of forest growth and utilization rate in 2010-2020 according to assumptions on forest management intensities as set in the forest reference level calculations. Actual "business as usual" scenario is used to estimate forest growth between 2010 and 2018, as well as for the projections of forest growth in 2019-2020 (Lazdiņš et al, 2019;Šņepsts et al, 2018). Data from National GHG inventory are used in calculations of forest growth, harvests and production of HWP (Ministry of Environmental Protection and Regional Development, 2021a).…”

Latvia is one of the largest exporters of pellets in Europe, and at the same time share of biofuel in energy production in Latvia is also one of the largest between the developed countries. Rapid increase of biofuel production and export raises questions about sustainability of forest sector and contribution of the forest biofuel produced in Latvia to the greenhouse gas (GHG) balance in Europe. Sustainability of forest biofuel is broadly discussed issue in Baltic states; particularly, due to continuous increase of production and export of wood pellets. GHG mitigation potential of the forest biofuel is one of the sustainability aspects surrounded by multiple speculations, which has to be addressed by comprehensive comparison of GHG fluxes due to production and use of forest biofuel and substituted fossil fuel. Assessment of the GHG mitigation potential of forest biofuel is complex process requiring multiple activity data and assumptions. Particular complexity of calculation is determined by the need to use harmonized approach for the whole calculation period. The assessment of the climate change mitigation in this study is based on the methods applied in National GHG inventory and literature data on GHG emissions due to production and delivery of substituted fossil fuel and forest biomass including demolition wood. According to the study results substitution effect of the forest biofuel in Latvia continuously increases since 2000, mainly due to export of biofuel, reaching 14323 Gg CO2 eq. in 2020 (by 30% more than the net GHG emissions in Latvia in 2019). Electricity production in pellet factories, in spite of major reduction of GHG emissions in the production process, has minor role in the total substitution effect.

The study compares 9 forest management scenarios in birch plantations in cropland and grassland with mineral and organic soils. Calculation period is 40 years for all scenarios. The study proves that establishment of birch plantations leads to reduction of greenhouse gas (GHG) emissions by 317-1776 tons of CO2 eq. ha -1 or 7.9-44.4 tons of CO2 eq. ha -1 per year. The reduction of GHG emissions in birch plantations is significantly influenced by growth conditionsin organic soils GHG emission reduction is 6 times higher than in mineral soils. In plantations with mineral soils most of the GHG emission reductions occur during 40 years after the establishment. In organic soils GHG emission reduction continues steadily due to reduction in GHG emissions from soils compared to alternative management scenarios (grassland or cropland). Harvested wood products and the substitution effect of biofuels play an important role in reducing GHG emissions, in particular through the assumption that wood products are recycled into biofuels at the end of their useful life. Recommended type of soil preparation in the most cases is mounding, but taking into account soil scarification costs, the number of target trees in the plantation must be reduced (down to 1500 per ha -1 ). Early tending, felling of young stands and regenerative felling must also be adapted to growing conditions by managing more intensively areas with fertile soils and less intensivelyplantations with poor soils. In more fertile soils higher planting density may increase CO2 removals in the middle term. When planting 1500-2000 seedlings ha -1 , moderately fertile soils ensures higher CO2 removals. According to the study results establishment of birch plantations in farmland is one of the most effective solutions for reducing GHG emissions in the land use, land use change and forestry (LULUCF), as well as in agriculture sector, especially, if organic soils are afforested.

“…The increase in forest area is expected to continue as a result of purposeful afforestation, as well as through the continued natural growth of forests on abandoned agricultural and non-agricultural lands. Additionally, forest biomass is increasing due to sustainable forest management in recent decades (Lazdiņš et al 2019). In 2015, for example, the gross annual increase in biomass was 16.9 million m 3 , while 10.6 million m 3 was harvested (see Appendix B for details).…”

“…The ability of these forests to sequester carbon is lower than that of young and premature forests (Latvian State Forest Research Institute Silava, 2017), where young forests sequester less than premature forests. The afforestation implemented over previous decades is expected to sequester increasing CO 2 emissions after 2030 (Lazdiņš et al, 2019). Old-growth forests serve especially the EU Biodiversity strategy 2030 goals.…”

The bioeconomy is considered a means to achieving a climate-neutral economy as aimed for in the EU Green Deal. For Latvia, the forest-based bioeconomy has the potential to contribute to this aim. An operational definition of the forest-based bioeconomy is needed to calculate its size. This research aims to provide such a definition and to determine the contribution of the forest-based bioeconomy to GDP, employment, and greenhouse gas emissions. The direct and indirect contribution of the forest-based bioeconomy to economic indicators and climate change is identified using an input-output model. The results of the model show that the forest-based bioeconomy contributes 6.4% to GDP and 6.6% to total employment in Latvia. The contribution to greenhouse gas emissions is 4.9%. Furthermore, if CO2 sequestration is included, the forest-based bioeconomy becomes climate neutral.
