“…Although several studies have suggested that the use of RES and renewable products can mitigate climate change [46], utilization of studies in practice has been difficult due to the different and unspecified analytical frameworks of energy efficiency measurements. It is clear that industrial supply networks are too complex to solve by simulation models [11].…”

“…Apart from simulation, in utilizing optimization frameworks the quantity value (energy relation between the renewable wood resource and fossil fuel consumption)-based energy efficiency measure (Model 7) could be recommended to indicate the attained energy efficiency level of the STS and LHVs for analytical reformulation on ecosystem optimization models. On the other hand, efficiency can often be expressed as a percentage of the result that could ideally be expected in some studies [42,46], but in wood supply networks' transport freight operation, efficiency was better to quantify with a non-percentage value. So, the used energy efficiency analysis provided a plausible measurement framework and novel insights into the relationships of transportation conditions and the transportation fleet combinations.…”

“…It is therefore also important to compare the energy efficiency of transportation fleets for fossil fuel consumption to the vehicle load's renewable wood energy utilization ( Figure 3). Over the past three decades, comparisons of energy efficiencies have been made by using modeling frameworks from the optimization, system simulation, or combined ecosystem methodologies [10,36,43,46]. According to the literature, numerous operations studies have been conducted for a quite small raw-material procurement region of a single heating plant system [47,48].…”

“…With respect to energy efficiency research frameworks, timber trucks' and forest machines' fossil fuel consumption has been investigated often in energy studies that relate to exhaust emissions [26,51]. Plants are also considered very often in research frameworks [46,52,53]. For example, Printz et al [46] used trucks' fuel economy (MWh l −1 ) to simulate the energy efficiency of the forest chip supply chain system.…”

The Finnish forest industry is committed to applying novel technologies for increasing carbon-neutral development and environmental sustainability in “green” circular industry. This study compares the energy efficiency indicators of road freight transportation. Additionally, effects of four mass limits of vehicle combinations are analyzed after a three-year adaptation process that took place in a wood procurement region of 100% renewable resources. The wood-based energy efficiency model (load’s wood energy/fossil transport energy) was the most accurate and precise measure as the development indicator. The indicator showed that the transportation systems (60, 64, 68, and 76 t) and (64, 68, and 76 t) were carbon negative (122, 133, 144, and 108) (142, 147, and 133) in 2014 and 2016, respectively. The numbers reveal positive energy ratio of renewable wood and fossil fuels. In comparison to 60 t, the use of 68 t vehicles increased energy efficiency most effectively in the systems, by 18.0% and 20.5%, respectively. The indicator robustly revealed the energy efficiency of a partial system in the smaller supply region, which depended on the region’s transportation conditions. This novel knowledge can be applied for advancing the adaptation toward carbon-neutral supply networks. There is also the development potential of an industrial ecosystem model for optimizing the environmental sustainability of “green” circular industry.

Context Mediterranean managed dry-edge pine forests maintain biodiversity and supply key ecosystem services but are threatened by climate change and are highly vulnerable to desertification. Forest management through its effect on stand structure can play a key role on forest stability in response to increasing aridity, but the role of forest structure on drought resilience remains little explored. Objectives To investigate the role of tree growth and forest structure on forest resilience under increasing aridity and two contrasting policy-management regimes. We compared three management scenarios; (i) “business as usual”-based on the current harvesting regime and increasing aridity—and two scenarios that differ in the target forest function; (ii) a “conservation scenario”, oriented to preserve forest stock under increasing aridity; and (iii), a “productivity scenario” oriented to maintain forest yield under increasingly arid conditions. Methods The study site is part of a large-homogeneous pine-covered landscape covering sandy flatlands in Central Spain. The site is a dry-edge forest characterized by a lower productivity and tree density relative to most Iberian Pinus pinaster forests. We parameterized and tested an analytical size-structured forest dynamics model with last century tree growth and forest structure historical management records. Results Under current management (Scenario-i), increasing aridity resulted in a reduction of stock, productivity, and maximum mean tree size. Resilience boundaries differed among Scenario-ii and -Scenario-iii, revealing a strong control of the management regime on resilience via forest structure. We identified a trade-off between tree harvest size and harvesting rate, along which there were various possible resilient forest structures and management regimes. Resilience boundaries for a yield-oriented management (Scenario-iii) were much more restrictive than for a stock-oriented management (Scenario-ii), requiring a drastic decrease in both tree harvest size and thinning rates. In contrast, stock preservation was feasible under moderate thinning rates and a moderate reduction in tree harvest size. Conclusions Forest structure is a key component of forest resilience to drought. Adequate forest management can play a key role in reducing forest vulnerability while ensuring a long-term sustainable resource supply. Analytical tractable models of forest dynamics can help to identify key mechanisms underlying drought resilience and to design management options that preclude these social-ecological systems from crossing a tipping point over a degraded alternate state.
