“…We used a climate indicator based on the average carbon storage in aboveground biomass across the planning period. Although we follow standard practice by discounting financial flows but not carbon storage, doing so implicitly weights the undiscounted objective, especially when uncertainty is high [74]. Our carbon indicator ignores product pools and substitution effects, but we expect that life-cycle analysis (LCA) would magnify the opportunity cost discrepancy between our case examples.…”

Considering in situ carbon storage in forest management has gained momentum under increasing pressure to decarbonize our economies. Here, we present results from case studies in Portugal and Germany showing the opportunity costs of in situ carbon storage derived by multiple-objective optimization. We used a stand-level model to optimize land expectation value under uncertainty as a reference, then derived opportunity costs by including the enhancement of the average carbon storage in aboveground biomass as a second objective. Using the optimal (compromise) solution when considering both objectives simultaneously, we show opportunity costs of EUR 119 (Portugal) and EUR 68 (Germany) per Mg CO2eq. These opportunity costs are higher than conservative, but lower than alternative cost estimates for future damages caused by current CO2 emissions. An important result was that suggested reference solutions in both countries (though only for low discount rates in Portugal) were mixed forests without clearfelling. In Germany, this implicitly elevated carbon storage. Such “closer-to-nature-forest-management” systems were also mostly suggested by the optimization tool when carbon storage was an objective.

“…Similarly, upon comparing the carbon sequestration potential of different forest management strategies, including different rotation ages and harvest intensities, Pukkala (2018) found that an increase in rotation age leads to higher carbon sequestration, but that other factors such as harvest intensity also have a significant impact. Both Assmuth et al (2021) and Jarisch et al (2022) provided meta-analyses of previous studies, focusing specifically on the relationship between carbon rotation ages and carbon sequestration in even-aged forests. They found that increasing rotation age leads to higher carbon sequestration, but that the relationship is nonlinear, with diminishing returns at longer rotation ages.…”

“…1 Discounting of future carbon fluxes was proposed by Schlamadinger and Marland (1999), and used by Johnston and van Kooten (2015) and Jarisch et al (2022), while decay (or residence time) in product pools was modelled by Härtl et al (2017). These studies did not, however, provide explicit analytic formulae for determining rotation age.…”

Sequestering carbon in forest ecosystems is important for mitigating climate change. A major policy concern is whether forests should be left unharvested to avoid carbon dioxide (CO2) emissions and store carbon, or harvested to take advantage of potential carbon storage in post‐harvest wood product sinks and removal of CO2 from the atmosphere by new growth. The issue is addressed in this paper by examining carbon rotation ages that consider commercial timber as well as carbon values. A discrete‐time optimal rotation age model is developed that employs data on carbon fluxes stored in both living and dead biomass as opposed to carbon as a function of timber growth. Carbon is allocated to several ecosystem and post‐harvest product pools that decay over time at different rates. In addition, the timing of carbon fluxes is taken into account by weighting future carbon fluxes as less important than current ones. Using simple formulae for determining optimal rotation ages, we find that: (1) Reducing the price of timber while increasing the price of carbon will increase rotation age, perhaps to infinity (stand remains unharvested). (2) An increase in the rate used to discount physical carbon generally reduces the rotation age, but not in all cases. (3) As a corollary, an increase in the price of carbon increases or reduces rotation age depending on the weight chosen to discount future carbon fluxes. (4) Site characteristics and the mix of species on the site affect conclusions (2) and (3). (5) A large variety of carbon offset credits from forestry activities could be justified, which makes it difficult to accept any.

Ieva Licite. PhD thesis: “Climate Change Mitigation in Agricultural Organic Soil Management in Latvia”, Jelgava, 2024. The research and evaluation of the situation provided the basis for formulating the hypothesis of the thesis: scientifically supported and data–based decision–making on organic soil management promotes the achievement of Latvia's climate policy goals. The objective of the doctoral thesis is to develop proposals for improving the agricultural organic soil management decision making to promote the achievement of Latvia's climate policy objectives. To achieve the set objective, the tasks are formulated as follows: 1) investigate the main theoretical and political aspects of organic soil management in agriculture for mitigating climate change; 2) evaluate the practice of organic soil management in Latvian agriculture and identify potentially cost–effective measures for reducing climate change; 3) assess and compare the cost–effectiveness of the identified climate change mitigation measures, preparing proposals for decision–making in organic soil management in agriculture. The thesis structure is organized according to the tasks and consists of three chapters with subchapters. The first chapter explores the theoretical and policy aspects of agricultural organic soil management in the context of climate change reduction, and the phenomenon of organic agricultural soil is explained. The second chapter analyses agricultural organic soil management in Latvia, including its connection to agricultural support policies, using spatial, factor, and cluster analysis. By using the expert survey method, potentially cost–effective climate change mitigation measures are identified. The third chapter provides a comparative evaluation of the cost–effectiveness of selected climate change mitigation measures, using a multi–criteria decision–making analysis method for ranking based on similarity to the ideal solution and a marginal abatement costs method. An assessment of the potential impact of the measures is carried out, and a simulation of greenhouse gas emission projections is prepared to evaluate the potential impact of climate change mitigation measures on the achievement of Latvia's climate change policy goals. In the conclusion of the thesis, the main research results and conclusions are formulated, research problems identified during the study are defined, and proposals for their resolution are put forward. The thesis for obtaining a scientific degree consists of 130 pages. The thesis includes 20 tables, 22 figures, 4 annexes, and references to 378 information sources, of which 352 in English.
