The study reports the CO2 emissions from diesel combustion in the following stages of the Brazilian ethanol supply chain: (a) agricultural operations (management), (b) sugarcane transportation to the mill, and (c) biofuel transportation to the destination. To assess the sensitivity of the results to different origins, five regions representative of ethanol production were selected, and the final destination was the port of Santos. The transportation stage from the mill to the port included the possible effects of using multimodal alternatives, such as road–rail and road–pipeline. The results indicate that diesel consumption varies greatly by region of origin, and agricultural management, such as tilling, planting, and harvesting operations, accounts for about 70% of total diesel emissions to the ethanol supply chain. Rail and pipeline transportation are ultimately important for mitigating emissions from fuel consumption in logistics corridors for exporting ethanol. It is a valuable contribution to supporting private actions and public policies related to the mitigation of emissions in the logistic stages of bioethanol, especially related to the optimization of the agricultural management process and improvement of the multimodal transport infrastructure, respectively. It is also a lesson to countries intending to produce ethanol from sugarcane.

Numerous studies addressed the impacts of social development and economic growth on the environment. This paper presents a study about the inclusive impact of social and economic factors on the environment by analyzing the association between carbon dioxide (CO2) emissions and two socioeconomic indicators, namely, Human Development Index (HDI) and Legatum Prosperity Index (LPI), under the Environmental Kuznets Curve (EKC) framework. To this end, we developed a two-stage methodology. At first, a multivariate model was constructed that accurately explains CO2 emissions by selecting the appropriate set of control variables based on model quality statistics. The control variables include GDP per capita, urbanization, fossil fuel consumption, and trade openness. Then, quantile regression was used to empirically analyze the inclusive relationship between CO2 emissions and the socioeconomic indicators, which revealed many interesting results. First, decreasing CO2 emissions was coupled with inclusive socioeconomic development. Both LPI and HDI had a negative marginal relationship with CO2 emissions at quantiles from 0.2 to 1. Second, the EKC hypothesis was valid for G20 countries during the study period with an inflection point around quantile 0.15. Third, the fossil fuel consumption had a significant positive relation with CO2 emissions, whereas urbanization and trade openness had a negative relation during the study period. Finally, this study empirically indicates that effective policies and policy coordination on broad social, living, and economic dimensions can lead to reductions in CO2 emissions while preserving inclusive growth.

The purpose of this article is to use strategy mapping (SM) and balanced scorecard (BSC) in portraying and assessing green entrepreneurial supply chain management (GESCM) performance of a vertically integrated entrepreneurial supply chain in an Egyptian emerging market of organic beverages industry. Based on thematic literature review and qualitative research (in-depth interviews with experts, focus groups, observations, and reports’ analysis), multi-item measurement quantitative BSC scale and strategy map were proposed to measure and communicate the GESCM performance of a hierarchical chain with multiple nodes and cross-functional green practices. This article conceptually contributes to the active debate on contemporary GESCM performance measurement. It integrates the literature of green production and operations management, strategic management and entrepreneurial supply chain management (ESCM) to investigate the unexplored context of GESCM research. It empirically assesses GESCM performance of an attractive network using BSC and maps its strategy with its multidisciplinary environment-friendly practices. The GESCM performance was measured in terms of four integrated perspectives (innovative and proactive processes, learning and growth, financial gains and supply chain stakeholders’ delight). Results showed that BSC and SM are effective and efficient tools in managing the performance of a successful GESC in an emerging market. Royal Herbs’ BSC key performance indicators (KPIs), which were used in assessing a GESCM strategy, indicate improvements along the BSC’s four perspectives. Results give green entrepreneurs/manufacturers in an emerging market as Egypt a comprehensive view on how they can effectively assess/improve their GESCM performance. It draws attention to the importance of investing in GESCM practices for maintaining sustainable development in a clean business environment. It helps practitioners, academics and policymakers in Egypt to bridge the gap between theory and practice regarding GESCM performance. From an interdisciplinary perspective, it provides insights on improving the ESCM performance of the industry without harming its natural environment.

This paper shows that decentralized supply chains, in which upstream firms use linear wholesale prices, may experience lower upstream production and downstream sales volatility than vertically integrated supply chains and may be less susceptible to the bullwhip effect by which the variance of upstream production exceeds the variance of downstream sales. The reason is that decentralized supply chains exhibit a price effect, whereby upstream producers raise wholesale prices in the case of positive demand shocks and lower wholesale prices in the case of negative demand shocks. Whereas upstream producers benefit from the price effect and, thus, from a dampening of the bullwhip effect, downstream firms may lose, and overall supply chain profit may decrease. This paper was accepted by Vishal Gaur, operations management.

The Karoo Meat of Origin certification scheme is the first certification scheme established to differentiate and protect a region of origin meat product in South Africa. Although this scheme has come a long way in protecting the value embedded in the name ‘Karoo’, many challenges and loopholes for non-compliance still exist. These challenges include opportunistic behaviour on the farmers’ side regarding the vulnerable free range claim as well as inconsistent supply and mismatched objectives of supply chain stakeholders. Because of these challenges the niche product has not yet come to its own. The purpose of this case study is threefold. Firstly, to understand the notion of Karoo Lamb as a geographical indication, and the subsequent establishment of the Karoo Meat of Origin certification scheme. Secondly, to identify and understand both the institutional and supply chain challenges that Karoo Lamb is faced with. Thirdly, to guide the certification scheme to evaluate their modus operandi for better regulation. Ultimately, the managerial decisions are expected to come full circle; if the certification scheme is better-managed consumers may be willing to pay higher premiums which might, in turn, convince farmers to become part of this prestigious certification scheme.

To reduce the amount of carbon dioxide released from transportation the EU has implemented legislation to mandate the renewable content of petrol and diesel fuels. However, due to the complexity of the combustion process the addition of renewable content, such as biodiesel and ethanol, can have a detrimental effect on other engine emissions. In particular the engine load can have a significant impact on the emissions. Most research that have studied this issue are based on steady state tests, that are unrealistic of real world driving and will not capture the difference between full and part loads. This study aims to address this by investigating the effect of renewable fuel blends of diesel, biodiesel and ethanol on the emissions of a compression ignition engine tested over the World Harmonised Light Vehicle Test Procedure (WLTP). Diesel, biodiesel and ethanol were blended to form binary and ternary blends, the ratios were determined by Design of Experiments (DoE). The total amount of emissions for CO, CO2 and NOx as well as the fuel consumption, were measured from a 2.4 liter compression ignition (CI) engine running over the WLTP drive cycle. The results depicted that percentages smaller than 10 % of ethanol in the fuel blend can reduce CO emissions, CO2 emissions as well as NOx emissions, but increases fuel consumption with increasing percentage of ethanol in the fuel blend. Blends with biodiesel resulted in minor increases in CO emissions due to the engine being operated in the low and medium load regions over the WLTP. CO2 emissions as well as NOx emissions increased as a result of the high oxygen content in biodiesel which promoted better combustion. Fuel consumption increased for blends with biodiesel as a result from biodiesel's lower heating value. All the statistical models describing the engine responses were significant and this demonstrated that a mixture DoE is suitable to quantify the effect of fuel blends on an engine's emissions response. An optimised ternary blend of B2E9 was found to be suitable as a 'drop in' fuel that will reduce harmful emissions of CO emissions by approximately 34 %, NOx emissions by 10 % and CO2 emissions by 21 % for transient engine operating scenarios such as the WLTP drive cycle.

<p>Supply chain management (SCM) is a critical factor in the current global scenario. This organizational capability has a recent knowledge base, which is being accumulated, validated, and certified by groups like the Association for Operations Management (APICS). Therefore, training in SCM has been growing as one of the most convenient ways of becoming “Certified in Production and Inventory Management” (CPIM) from APICS. Companies all over the world have invested in SCM training; however, some companies have conditioned the continuity of their training programs to the benefits assessment. This paper contributes by proposing an evaluation model for specific program training on SCM. This model was applied in a global chemical company, which allowed capturing its impact on organizational and individual competencies, as well as on the core competencies. The proposed model includes the Analytic Hierarchy Process (AHP) and concepts in the SCM literature. The main result revealed by this research is that an SCM training based on APICS CPIM is really perceived as beneficial, in individual or organizational terms, for a real-world company. Therefore, this company should be confident that its SCM training program is improving and strengthening its core competencies.</p>

<p><em>Increasing economic growth will spark against increased energy consumption. But on the other hand, increasing economic growth will also trigger the occurrence of natural damage and degradation of environmental quality derived from CO2 emissions. CO2 emissions are caused by oxidation process of fossil fuel energy. This research aims to know the causality relationship between CO2 emissions, fossil fuel consumption, electricity consumption, and economic growth in Indonesia, as well as long-term relationship between CO2 emissions, fossil fuel consumption, electricity consumption, to economic growth in Indonesia in 1990 – 2019. The used data is the secondary data that is in the form of data time series. The dependent variables of this study are economic growth, while independent variables are CO2 emissions, fossil fuel consumption, electricity consumption. The method that is used in this study is Vector Error Correction Model. The results showed that there was a one-way causality between economic growth and fossil fuel consumption, and between electricity consumption and CO2 emissions. The research also shows that on long-term CO2 emissions has a negative influence, while the consumption of fossil fuels and electricity has a positive effect on Indonesia's economic growth in 1990-2019.</em></p><p><strong><em>K</em></strong><strong><em>eywords</em></strong><em>: CO2, Energy Consumption, Economic Growth.</em></p>
