“…In the opinion of the authors of this forecast, this will be the result of, first of all, two processes: the aging of Polish forests and a decrease in the area of afforestation [Seventh National … 2017]. The view that active forest management increases the absorption of carbon dioxide, due to the fact that with the maturation of forests, the primary net productivity decreases, and the natural mortality of the forest stand increases, and consequently the rate of carbon dioxide absorption decreases [Hektor et al 2016;Nabuurs 2003] is often used to justify the strategy of the State Forests. It is also indicated that the risk of losses from fires and diseases increases with age.…”

Climate change will have a significant impact on forests as most of the factors determining their condition are modified by the effects of the climate change process. Some of these effects are a change in the distribution and amount of precipitation, an increase in the frequency of extreme meteorological phenomena, including hurricane winds, temperature distribution, or a change in the length of the growing season. In order to maintain the productivity of Polish forests and the range of ecosystem services they provide, the forestry sector will have to adapt to these changes. However, forestry will also have to take a part in holding back climate change. Achieving climate neutrality by mid-21st century and ensuring a 55% reduction in greenhouse gas emissions by 2030 will not be possible without using the ability of forests to absorb and permanently store carbon. Polish forestry seems to be insufficiently prepared for the challenges ahead. A new national forestry policy has not been developed in the past twenty years, which results, inter alia, in a lack of any clear indication of the role of Polish forests in climate protection. Adaptation to the effects of climate change is hampered by the lack of up-to-date, detailed scenarios of how this process will affect the climate factors in Poland. Particularly dangerous, in light of the role of forests in climate protection, is a significant decrease in the afforested area, which in turn leads to a reduction in the amount of carbon absorbed by them. Another obstacle to implementation of effective measures may be the growing disparity between the current forestry practice and social expectations, as well as a low degree of willingness from the State Forests to cooperate with stakeholders who present different opinions on how to conduct forest management. This obstacle may lead to disputes about the management of Polish forests at the European Union level and rulings of the Court of Justice of the European Union. The conducted analyses showed that cooperation with a wide range of stakeholders will be the basic condition for the inclusion of Polish forests in the implementation of climate policy objectives on a greater scale. It should help define the role of this sector in this process, implement the necessary adaptative and climate protection measures, and support activities aimed at acquiring new land for afforestation.

“…unmanaged forests increase the chance of massive carbon losses from disturbances (Hektor et al, 2016). Harvesting mature trees and replanting could therefore increase the rate of carbon uptake, as well as generating timber for wood products.…”

“…The saturation limits on soils as carbon sinks, even with biochar application, are well recognised (EASAC, 2018); the saturation and sequestration dynamics of trees and forests are more complex, however, and there is little consensus in the literature on the most appropriate forest management regime for maximising carbon uptake. Probably the most commonly accepted view is that active forest management enhances carbon uptake, both because the rate of carbon uptake slows as forests mature, net primary productivity declines and natural mortality increases, and also because unmanaged forests increase the chance of massive carbon losses from disturbances (Hektor et al, 2016). Harvesting mature trees and replanting could therefore increase the rate of carbon uptake, as well as generating timber for wood products.…”

Managing Land‐based CDR: BECCS, Forests and Carbon Sequestration

Decisions about when, where and how to achieve widespread carbon dioxide removal (CDR) are urgently required. Delays in developing the requisite policy and regulatory frameworks increase the risks of overshooting climate goals and will necessitate much larger negative emissions initiatives in the future. Yet the deployment of bioenergy with carbon capture and storage (BECCS) at the scales assumed under most Paris‐Agreement‐compliant emission‐reduction pathways is unlikely. More generally, the sustainability of large‐scale BECCS is questionable given its extensive land, water, and energy requirements for feedstocks and the competing necessity of these resources for the provision of ecosystem services and attainment of multiple Sustainable Development Goals. BECCS on a more limited scale, however, could have more benign impacts if feedstocks were restricted to wastes and residues. There is also widespread recognition that extensive afforestation, reforestation and forest restoration have critical roles in reducing greenhouse gas emissions to net zero. To date there has been little focus on the optimum strategies for integrating land‐based CDR approaches – under which circumstances forest areas are best left undisturbed, managed for conservation, and/or managed for harvested wood products, and how these options affect the availability of residual feedstocks for BECCS. This paper reviews this debate and suggests appropriate policy measures.

“…Therefore, the intended application of this study was to provide credited data and enhance our knowledge on environmental aspects associated with conversion of forest residues to bioenergy carriers using the torrefaction process at a life-cycle level. Torrefaction allows production of a renewable and carbon-neutral solid biomass energy resource (Hektor andothers 2016, Miner andothers 2014). Hence, the assessment also includes comparison of the torrefied wood production with use of traditional fuel, i.e., propane, for domestic heating to evaluate its environmental performance compared with traditional fossil energy sources.…”

This report presents life-cycle impact assessment analysis of near-woods processing of post-harvest forest residues (a biomass raw material) into torrefied wood for bioenergy production. The study was part of the Waste to Wisdom project with a broader goal of evaluating the use semimobile biomass conversion technologies to optimize biomass logistics, thereby overcoming the barriers of valorizing woody biomass residues for renewable energy and material production. Cradle-to-grave analysis of the torrefied briquettes (TOB) supply chain included feedstock procurement, hauling, feedstock preparation and bioconversion (torrefaction and densification) stages, product transportation (distribution), and combustion of TOB in domestic wood stoves for heat generation. The results showed that a large portion of the global warming (GW) impact of the TOB supply chain resulted from the torrefaction process (59%) followed by the drying process with about 24% of the contribution. The large contribution of these processes resulted from propane use. Comparative analysis showed that 50% substitution of propane used in domestic heating with TOB resulted in a 41% decrease in GW impact. The near-woods operation resulted in a 55% lower GW impact compared with transporting the feedstock to an in-town facility with access to grid electricity.
