The Impact

Afforestation and reforestation (AR) is an important component of China’s Greenhouse Gases (GHG) Voluntary Emission Reduction Program, acting as a valuable nationwide carbon sink. Although a number of studies have explored the costs of creating a carbon sink, such an assessment is lacking for China’s GHG Voluntary Emissions Reduction Program. This study develops an economic carbon sink costs measurement model for the Pinus elliottii afforestation project, based on the land opportunity cost method, which incorporates carbon sink transaction costs and leakage costs. From this, an empirical analysis on the carbon sink costs and its sensitivity factors was conducted. The results show that, firstly, the carbon sequestration costs of afforestation projects are generally high, ranging from 44.2 Yuan/tCO2e to 425.4 Yuan/tCO2e with and without considering the benefits of wood, respectively. This is higher than the current average carbon sink price of 20 Yuan/tCO2e. Secondly, forestry carbon sink transaction costs have a positive impact on carbon sequestration costs, but the impact is weak. Thirdly, carbon sequestration costs are negatively affected by timber prices but positively influenced by increasing labor prices and discount rate, which is not conductive to the development of carbon sink afforestation projects. In order to strengthen role of forestry in combating climate change, the study holds that the government departments should take measures to reduce carbon sink transaction costs, establish and improve the forestry carbon sink compensation mechanism in the future, and encourage wood-processing companies to make technological innovations to produce and sell durable wood products. The project owners can explore multiple operating models to increase their revenue, including market and non-market benefits, when the carbon sink afforestation project has been launched according to relevant methodologies.

Reduction Costs

We consider a capital constrained timber and carbon sink supply chain under the cap-and-trade scheme, where the forest company produces timber and carbon sink. We consider two subsidy modes: financing subsidy to the carbon sink forests and financing subsidy to the manufacturer’s emission reductions. We apply a Stackelberg model and mainly consider the impact of subsidies on the profits and the strategies of the supply chain members. The results show that when the government gives a financing subsidy to the carbon sink forests, it is conducive to promoting the expansion of carbon sink forests, as well as the enhancement of the forest company’s profit. However, a larger supply of carbon sinks generates a lower price, which leads to the manufacturer reducing the technical emission reduction level and purchasing more carbon emission rights instead. On the other hand, when the manufacturer receives a financing subsidy for the technical emission reduction costs, its production becomes cleaner than before, and the profits of the forest company and the manufacturer increase.

Abstract As a part of a larger study concerning the carbon sequestration capability by hazelnut orchards in Italy, we analyzed the total amount of carbon dioxide (CO2) removed over the year from the atmosphere through the net assimilation rates in two hazelnut orchards in Piedmont (i.e., the second region in Italy for surface and production). In particular, considering the key role played by the structural traits in affecting carbon sequestration potential, we assessed the impact of two different training systems widely diffused in the region: single trunk in orchardA and bush-like in orchardB. The results showed that plants in orchardA and orchardB sequestered 10.6 ± 1.8 and 25.7 ± 4.2 kg (CO2) plant−1 month−1, respectively. Higher CO2 sequestration in the plants in orchardB was due to their higher leaf area index relative to plants in orchardA. The mean CO2 sequestration from orchardA and orchardB per area was 4.25 ± 1.72 and 8.57 ± 3.41 Mg (CO2) ha−1 month−1, respectively. We also estimated the total amount of CO2 emission by the management over the entire production season in 157.335 kg CO2eq ha−1 by summing the contribution of diesel fuel, machinery and fertilization practices and considering that the total amount of CO2 sequestered by the two hazelnut orchards over the entire study period was estimated in 26 Mg (CO2) ha−1 in orchardA, and in 51 Mg (CO2) ha−1 in orchardB, they had an effective positive role as carbon sink at this local level.

<p>The COVID-19 pandemic struck China in January 2020 and the rest of the world from February 2020 onwards. Public authorities enforced several kinds of lockdowns in order to limit the spread of the pandemic and reduce its impact on the health system: at the height of the first wave of the pandemic, more than one human in two was subjected to a lockdown, with associated disruption in local and international travel, industry, tourism etc. These lockdowns had a profound effect on anthropogenic emissions of aerosol, trace gases and greenhouse gases; in this work we focus on aerosols and a selection of trace gases.<br><br>The Integrated Forecasting System (IFS) of ECMWF is core of the Copernicus Atmosphere Monitoring Service (CAMS) to provide global analyses and forecasts of atmospheric composition, including reactive gases, as well as aerosol and greenhouse gases.

These simulations also provided information on how the aerosol speciation was altered by the COVID-19 lockdowns: over Europe and the U.S., most of the decrease in surface aerosols was simulated to come from nitrate aerosols. Over the U.S., this matched well with observations of speciated aerosols at surface.</p>

Purpose Emission reduction methodologies alone are not sufficient to mitigate the climatic catastrophes caused due to ongoing carbon emissions. Rather, a bidirectional approach is required to decarbonize the excess carbon in the atmosphere through carbon sequestration along with carbon reduction. Since the manufacturing sector contributes heavily to the ongoing carbon emissions, the purpose of this paper is to propose a framework for carbon emission reduction and carbon sequestration in the context of the manufacturing industry. Design/methodology/approach In this paper, life cycle assessment (LCA) is employed to track the carbon emission at each stage of the product development life cycle. The pre-requisite for this is the accurate evaluation of the carbon emissions. Therefore, IoT technologies have been employed for collecting real-time data with high credibility to perceive environmental impact caused during the entire life cycle of the product. The total carbon emission calculation is based on the bill of material (BOM)-based LCA of the product to realize the multi-structure (from parts and components to product) as well as multi-stage (from cradle to gate) carbon emission evaluation. Carbon sequestration due to plantation is evaluated using root-shoot ratio and total biomass. Findings A five interwoven layered structure is proposed in the paper to facilitate the real-time data collection and carbon emission evaluation using BOM-based LCA of products. Further, a carbon neutral coefficient (CNC) is proposed to indicate the state of a firm’s carbon sink and carbon emissions. CNC=1 indicates that the firm is carbon neutral. CNC >1 implies that the firm’s carbon sequestration is more than carbon emissions. CNC <1 indicates that the firm’s carbon emission is more than the carbon sink. Originality/value The paper provides a novel framework which integrates the real-time data collection and evaluation of carbon emissions with the carbon sequestration.

Abstract Background Replacing non-renewable materials and energy with wood offers a potential strategy to mitigate climate change if the net emissions of ecosystem and technosystem are reduced in a considered time period. Displacement factors (DFs) describe an emission reduction for a wood-based product or fuel which is used in place of a non-wood alternative. The aims of this review were to map and assess DFs from scientific literature and to provide findings on how to harmonise practices behind them and to support coherent application. Results Most of the reviewed DFs were positive, implying decreasing fossil GHG emissions in the technosystem. The vast majority of the reviewed DFs describe avoided fossil emissions either both in processing and use of wood or only in the latter when wood processing emissions were considered separately. Some of the reviewed DFs included emissions avoided in post-use of harvested wood products (HWPs). Changes in forest and product carbon stocks were not included in DFs except in a few single cases. However, in most of the reviewed studies they were considered separately in a consistent way along with DFs. DFs for wood energy, construction and material substitution were widely available, whereas DFs for packaging products, chemicals and textiles were scarce. More than half of DFs were calculated by the authors of the reviewed articles while the rest of them were adopted from other articles. Conclusions Most of the reviewed DFs describe the avoided fossil GHG emissions. These DFs may provide insights on the wood-based products with a potential to replace emissions intensive alternatives but they do not reveal the actual climate change mitigation effects of wood use. The way DFs should be applied and interpreted depends on what has been included in them. If the aim of DFs is to describe the overall climate effects of wood use, DFs should include all the relevant GHG flows, including changes in forest and HWP carbon stock and post-use of HWPs, however, based on this literature review this is not a common practice. DFs including only fossil emissions should be applied together with a coherent assessment of changes in forest and HWP carbon stocks, as was the case in most of the reviewed studies. To increase robustness and transparency and to decrease misuse, we recommend that system boundaries and other assumptions behind DFs should be clearly documented.

Forestry Sector

Projects in the forestry sector, and land-use change and forestry projects more generally, have the potential to help mitigate global warming by acting as sinks for greenhouse gasses, particularly CO2. However, concerns have been expressed that participation in carbon-sink projects may be constrained by high costs. This problem may be particularly severe for projects involving smallholders in developing countries. Of particular concern are the transaction costs incurred in developing projects, measuring, certifying, and selling the carbon-sequestration services generated by such projects. This paper addresses these issues by reviewing the implications of transaction and abatement costs in carbon-sequestration projects. An approach to estimating abatement costs is demonstrated through four case studies of agroforestry systems located in Sumatra, Indonesia. A typology of transaction costs is presented and related to existing pilot projects. The paper concludes with recommendations to reduce the disadvantages that smallholders may face in capturing the opportunities offered by carbon markets.

The Impact

Carbon sequestration is suggested as a low-cost option for climate change mitigation, the functioning of which can be threatened by pathogen infestation. This study calculates the effects of infectious pathogens on the cost of achieving the EU’s 2050 climate targets by combining the so-called production function method with the replacement cost method. Pathogens are then assumed to affect carbon sink enhancement through the impact on productivity of forest land, and carbon sequestration is valued as the replacement for costly reductions in emissions from fossil fuels for reaching the EU’s 2050 climate targets. To this end, we have constructed a numerical dynamic optimization model with a logistic forest growth function, a simple allometric representation of the spread of pathogens in forests, and reductions in emissions from fossil fuels. The results show that the annual value of forest carbon sequestration ranges between approximately 6.4 and 14.9 billion Euros, depending on the impact and dispersal of pathogens. Relatively large values are obtained for countries with large emissions from fossil fuels, e.g., Germany, France, Spain and Italy, which also face costs of pathogen together with countries with large forest area, such as Romania.

Stock Change

Abstract Background There are multiple approaches for estimating emissions and removals arising from harvested wood products (HWP) based on differences between when and where a given carbon stock change is calculated. At this moment, countries are free to use any HWP approach to prepare their annual greenhouse gas (GHG) inventory and determine emission reduction targets for their Nationally Determined Contributions (NDCs), although under the Paris Agreement (PA), the production approach is used for standard reporting in GHG inventories. Global double-counting and non-counting of HWP might occur depending on the HWP approach each country uses; however, the impact of such double-counting and non-counting has not been thoroughly evaluated. Results We identified all cases of global double-counting and non-counting of HWP for combinations of the six HWP approaches: ‘instantaneous oxidation’, ‘stock-change’, ‘production’, ‘stock-changes approach for HWP of domestic origin (SCAD)’, ‘simple-decay’ and ‘atmospheric-flow’ approaches. In Intended Nationally Determined Contributions (INDCs), forest land is often partly or completely excluded, especially by developing countries. In such cases, HWP approaches that require comprehensive national data on wood harvesting and trade are not suitable for estimating HWP contributions. In addition, most developing countries apply the ‘instantaneous oxidation’ at the time of harvesting. Recent GHG inventories from Annex I countries show the averaged contribution of annual HWP emissions or removals to national total emissions is nearly 1%; therefore, the potential contribution of HWP to the accounted emission reduction volume is assumed to be a smaller value. Conclusions Instantaneous oxidation remains a pragmatic approach for countries in which wood production is not a dominant part of the economy. The combination of ‘instantaneous oxidation’ with the ‘production’, ‘SCAD’ or ‘simple-decay’ approaches could be a practical solution to realize a global HWP accounting approach the eliminates double-counting. Regardless of how global double-counting and non-counting occur, the amount is not large. To improve the accuracy of the global assessment, it is important to reduce the uncertainty of estimation regarding when and how much HWP-related emissions occur at national level.

The Impact

The influence of industrial agglomeration on corporate export behavior has been widely studied by both industry and academia. However, few studies have explored the impact of the spatial agglomeration of China’s wood processing industry on the quality of its products at the micro level. In this study, we analyzed data from the China Customs Database to determine the quality of wood processing industry products at the enterprise level. Then, we matched the China Customs Database with the data in the China Industrial Enterprise Database. Based on this, we analyzed the impact of the spatial agglomeration on the quality of wood products using panel data regression. According to our results, spatial agglomeration of the wood processing industry can significantly improve product quality. Also, private enterprises are more likely to benefit from the advantages conferred by agglomeration than state-owned enterprises. Moreover, trade method does not significantly modulate the effect of spatial agglomeration on the quality of wood products. Last but not least, the agglomeration has the most significantly positive impact on the quality of products produced by the wood chip processing industry, followed by the wood products industry and the wood panel industry. Agglomeration of the bamboo and rattan palm industry actually decreases product quality. Therefore, we encourage agglomeration of timber processing enterprises, especially privately owned wood chip, wood product, and wood panel enterprises, to fully realize the benefits of the agglomeration economy. We also make policy recommendations to improve wood product quality.

Reduction Of Co2

With the ratification of the Kyoto Protocol aimed at reducing greenhouse gases, Switzerland is committed to reducing CO2emissions by 4.2 million tonnes by 2008. The forests in Switzerland could contribute to the country's national carbon balance with maximum 1.8 million tonnes reduction of CO2. With an increased use of the forest the emissions could be reduced by up to 2 million tonnes by the substitution of other materials. With a targeted forest management policy carbon sink reduction and the substitution value of the forest could be balanced against one another. In the framework of climate policy the Federal government should create the legal and organisational conditions for this.
