ABSTRACT
Cleaning and saving the forest is related to managing and utilizing forests' biodiversity, productivity, and considering the relevant environment. Plastic waste management is now seen as an important goal for sustainable forest use as well as incorporating recycled plastics into products. Another way that industries impact wildlife and forests is by releasing additives such as industrial gases, organic & inorganics materials, plastic & resins, fertilizers & alkalies, and chlorine. Polymer wastes manage to enter into and harm numerous biological functions of animals. In this work, the concept of sustainable Türkiye's forest practices and addressing the impact of plastic waste on the forests and environment before and during the COVID-19 epidemic are discussed along with current sources of those mentioned materials wastes that manage to enter the environment. Through this work, the data of bio thermochemistry and thermodynamics calculations of such polymers have been investigated to exhibit the range of sustainability and unsustainability of those mentioned polymers and resins in the environment due to forest climate change. Since the Türkiye chemical industry is one of the most important industrial factors, their production contributes in similar proportions to greenhouse gas emissions. Interestingly, low data on energy usage in the factories and chemical industry is available in the public domain. Ethylene production is the major product in terms of the production volume of the petrochemical industry. Nitrogenous fertilizer production is a very energy-intensive industry, producing a variety of fertilizers and other nitrogen compounds. In addition, ammonia, chlorine, and caustic soda are the most important mediator chemical material used as the main compound for almost all products. © 2023 by the authors.
ABSTRACT
The global outbreak of COVID-19 caused serious threats to public health and economic growth all around the world, but on the other hand, the betterment of the environment took place. How pandemics' health uncertainty will affect environmental quality is a crucial matter to address. The paper investigates the asymmetric association between pandemics-related health uncertainty and greenhouse gas emissions (GHG) in the top emitter European Union economies (Italy, Germany, France, Poland, Netherlands, Spain, Czech Republic, Belgium, Romania, and Greece). Employing data from 1996 to 2019, a unique approach called 'Quantile-on-Quantile', is adopted to evaluate the influence of various quantiles of the health uncertainty on GHG emissions. According to estimates, health uncertainty enhances environmental quality by minimizing GHG in most of our chosen nations at certain quantiles of data, which makes pandemics a blessing in disguise for environmental quality. Additionally, the estimations indicate that the grades of asymmetry between our variables varies by locality, accentuating the requisite for authorities to give specific consideration while executing health uncertainty and environmental quality policies.
ABSTRACT
The last century has witnessed European commercial aviation flourishing at the cost of environmental degradation by boosting greenhouse gas and CO2 emissions in the atmosphere. However, the outcry for net-zero emissions compels the sector's supply chain to a minimum 55% reduction of greenhouse gas emissions below the 1990 level by 2030 and zero CO2 emissions by 2050. This study examines a European environmental sustainability path toward a green commercial aviation supply chain. Driven by literature and a review of related documents, two propositions were advanced to orient perspectives on the relationship between pollution and the commercial aviation supply chain and actions being taken toward environmental sustainability. In semi-structured interviews, seventeen aerospace associates endorsed pollution sources in the commercial aviation supply chain during the four stages of the aircraft life cycle, including extracting the raw materials, manufacturing, ground and flight operations, and end-of-service. They recommended transitioning into green commercial aviation through the widespread deployment of innovative technologies, from modifying airframes to changing aviation fuel, utilizing alternative propulsion systems, adopting circular manufacturing, and improving air traffic management.
ABSTRACT
Background and Objective: There have been significant effects of the current coronavirus-19 (COVID-19) infection outbreak on many facets of everyday life, particularly the environment. Despite the fact that a number of studies have already been published on the topic, an analysis of those studies' findings on COVID-19's effects on environmental pollution is still lacking. The goal of the research is to look into greenhouse gas emissions and air pollution in Bangladesh when COVID-19 is under rigorous lockdown. The specific drivers of the asymmetric relationship between air pollution and COVID-19 are being investigated. Methods: The nonlinear relationship between carbon dioxide ( C O 2 ) emissions, fine particulate matter ( P M 2 . 5 ) , and COVID-19, as well as its precise components, are also being investigated. To examine the asymmetric link between COVID-19 factors on C O 2 emissions and P M 2 . 5 , we employed the nonlinear autoregressive distributed lag (NARDL) model. Daily positive cases and daily confirmed death by COVID-19 are considered the factors of COVID-19, with lockdown as a dummy variable. Results: The bound test confirmed the existence of long-run and short-run relationships between variables. Bangladesh's strict lockdown, enforced in reaction to a surge of COVID-19 cases, reduced air pollution and dangerous gas emissions, mainly C O 2 , according to the dynamic multipliers graph.
ABSTRACT
Climate change has become mankind's main challenge. Greenhouse gas (GHG) emissions from shipping are not totally irresponsible for this representing, roughly, 3% of the global total;an amount equal to that of Germany's total GHG emissions. The Fourth Greenhouse Gas Study 2020 of the International Maritime Organization (IMO) predicts that the share of GHG emissions from shipping will increase further, as international trade recovers and continues to grow, alongside with the economic development of India, China, and Africa. China and the European Union have proposed to include shipping in their carbon emissions trading systems (ETS). As a result, the study of the relationship between the carbon finance market and the shipping industry, attempted here for the first time, is both important and timely, both for policymakers and shipowners. We use wavelet analysis and the spillover index methods to explore the dynamic dependence and information spillovers between the carbon finance market and shipping. We discover a long-term dependence and information linkages between the two markets, with the carbon finance market being the dominant one. Major events, such as the 2009 global financial crisis;Brexit in 2016;the 2018 China-US trade frictions;and COVID-19 are shown to strengthen the dependence of carbon finance and shipping. We find that the dependence is strongest between the EU carbon finance market and dry bulk shipping, while the link is weaker in the case of tanker shipping. Nonetheless, carbon finance and tanker shipping showed a relatively stronger dependence when OPEC refused to cut production in 2014, and when the China-US trade disputes led to the collapse of oil prices after 2018. We show that information spillovers between carbon finance and shipping are bidirectional and asymmetric, with the carbon finance market being the principal transmitter of information. Our results and their interpretation provide guidance to governments on whether (and how) to include shipping in emissions trading schemes, supporting at the same time the environmental sustainability decisions of shipping companies. © 2023 The Authors
ABSTRACT
The impact of anthropogenic greenhouse gas emissions on the increase in the average temperature on the planet and the risk of initiating irreversible processes are recognized by most of the scientific community as real threats to humanity. Many countries have a legal and institutional framework for a consistent industrial policy taking into account the climate and environmental components, including carbon accounting. Russia is a country with high intensity of production-based CO2 emissions. In is well-known that the industry generates necessary hence it induce demand for products from other sectors of the economy. Environmental and social parameters in the formation of industrial policy should not be considered as any limitations for the development of industry. Despite a serious change in the agenda for the industrial policy in recent years, caused by COVID-19 and by current geopolitical situation in the world, it is highly undesirable to lag behind in this area, since it is necessary for international cooperation and human technological development. Low-carbon areas correspond to the modern ideology of industrial policy for many countries. The novelty of the study is the evaluation of the total GHG (greenhouse gases) intensity of Russias industry by means of intersectoral model. The paper analyses some of industrial policy measures and their implementation that affect low-carbon economic development. The proposed study could be of interest for other economies aiming to reduce their carbon footprint. © 2022 International Multidisciplinary Scientific Geoconference. All rights reserved.
ABSTRACT
Southeast Asia is one of the world's most energy-intensive and climate vulnerable regions, with rapid urbanization and industrialization increasing its greenhouse gas emissions and a high exposure to extreme weather events. The COVID-19 pandemic has had a massive impact on the region's economic growth. Decisions taken by leaders today to revive economies will either entrench the region's dependence on fossil fuels or accelerate decarbonization efforts to achieve the Paris Agreement and the Sustainable Development Goals. This article recalls the imperative of a green, climate resilient recovery from the COVID-19 pandemic to put ASEAN economies on a sustainable and inclusive development path before discussing the chronic infrastructure investment gap and reviewing options to catalyze climate investment to address this gap and finance recovery efforts. © 2023 American Institute of Chemical Engineers.
ABSTRACT
The COVID-19 pandemic forced upon the world, severe social distancing restrictions, which led to prolonged confinement across populations. The latter directly impacted actors along the supply chain in a variety of industrial sectors (for instance, raw material suppliers, manufacturers, distributors, and customers, among others). Some actors involved had to cease participation altogether due to closures. As a result, the supply chain requires restructuring and its reactivation requires careful consideration. In addition to the pandemic, poor air quality has brought about an environmental crisis in recent years. Primary polluters include greenhouse gas (GHG) emissions caused by manufacturers and distributors. Therefore, this research studies the problem of restructuring a particular multicommodity and hierarchized supply chain. Specifically for companies dealing with situations derived from a reduction in manufacturing capacity and service level in light of the pandemic. In this case, a company (leader) is faced with selecting customers that it will service in pursuit of maximizing profit, all while looking to minimize GHG emissions. The consolidated demand is nearshored once the leader company decides on the customers to be supplied. That is, an order is placed on a company with a lower hierarchy (follower). The follower, in turn, aims to minimize its own manufacturing costs without exceeding the pollution limits imposed by the government. However, its manufacturing plan inevitably pollutes and incurs different costs. In addition, the follower's decisions impact both leader's objective functions. We propose a bi-objective bi-level programming model to study this situation. To solve the problem in reasonable computational time, a heuristic algorithm that takes into account existing asynchrony between leader and follower companies is proposed to approximate the Pareto front. Computational experimentation reveals that the proposed algorithm provides good trade-off solutions, which can reduce GHG emissions by 67% on average without significantly affecting company revenue. Moreover, the algorithm is able to provide solutions for instances of up to 1000 nodes in a competitive computational timeframe. In addition, we discuss the advantages of computing GHG emissions proposed herein. Finally, useful managerial insights are discussed by performing a sensitivity analysis regarding the distribution company's minimum acceptable level of profit. © 2023 Elsevier Ltd
ABSTRACT
Since the containment measures placed in several countries to deal with Covid-19 pandemic, air and noise pollution has been significantly reduced, but what about soil pollution and greenhouse gas emissions from waste management? Covid-19 has given a break to the earth by immobilizing a very large part of the world economy, industrial activity, and transport and by having an important modification on the Moroccan consumer behaviour. This demographic evolution and change of consumption do not infect the resources, but are a source of degradation and pollution of the different environmental components. Among these sources, we find the production of household and similar waste. Our objective is to rate the impact of this pandemic on waste production, in Ajdir landfill, El Hoceima, which reflects the activity of the Moroccan citizen (between March 20 and April 27, 2020), and the initiatives that have been taken and launched to solve the problems at the level of each province through the establishment of a provincial master plan for the management of household and similar waste. © 2023, The Author(s), under exclusive license to Springer Nature Switzerland AG.
ABSTRACT
The impact of the climate change response on the labour market is an important question for policymakers, while the net positive effect of green policies on the labour market is seen as one of the arguments in favour of a green transition. This is particularly important for the tourism labour market, which was severely hit by the COVID-19 pandemic. This study examined the effect of carbon taxes on tourism employment for European countries that have levied a carbon tax over the past thirty years. A macroeconomic panel data regression model ex-post study was applied by contrasting the obtained results via a robustness check. The estimation results indicate a slightly positive and significant association between the carbon tax and tourism employment, which was additionally tested by considering revenue recycling, early adopters of the carbon tax, and a higher carbon tax compared to countries with a lower carbon tax. We cannot conclude that these factors matter for tourism employment, proving the robustness of the results. Revenue-neutral carbon taxation, policies to address the skills gap, push and pull incentives, and active labour market policies to facilitate the quick re-integration of jobseekers into employment are viewed as pivotal to ensure a smoother transition toward a sustainable tourism labour market. © 2023 by the author.
ABSTRACT
Pit latrines are widely promoted to improve sanitation in low-income settings, but their pollution and health risks receive cursory attention. The present narrative review presents the pit latrine paradox; (1) the pit latrine is considered a sanitation technology of choice to safeguard human health, and (2) conversely, pit latrines are pollution and health risk hotspots. Evidence shows that the pit latrine is a 'catch-all' receptacle for household disposal of hazardous waste, including; (1) medical wastes (COVID-19 PPE, pharmaceuticals, placenta, used condoms), (2) pesticides and pesticide containers, (3) menstrual hygiene wastes (e.g., sanitary pads), and (4) electronic wastes (batteries). Pit latrines serve as hotspot reservoirs that receive, harbour, and then transmit the following into the environment; (1) conventional contaminants (nitrates, phosphates, pesticides), (2) emerging contaminants (pharmaceuticals and personal care products, antibiotic resistance), and (3) indicator organisms, and human bacterial and viral pathogens, and disease vectors (rodents, houseflies, bats). As greenhouse gas emission hotspots, pit latrines contribute 3.3 to 9.4 Tg/year of methane, but this could be an under-estimation. Contaminants in pit latrines may migrate into surface water, and groundwater systems serving as drinking water sources and pose human health risks. In turn, this culminates into the pit latrine-groundwater-human continuum or connectivity, mediated via water and contaminant migration. Human health risks of pit latrines, a critique of current evidence, and current and emerging mitigation measures are presented, including isolation distance, hydraulic liners/ barriers, ecological sanitation, and the concept of a circular bioeconomy. Finally, future research directions on the epidemiology and fate of contaminants in pit latrines are presented. The pit latrine paradox is not meant to downplay pit latrines' role or promote open defaecation. Rather, it seeks to stimulate discussion and research to refine the technology to enhance its functionality while mitigating pollution and health risks.

The marine transportation industry, which has made significant steps in recent years to combat climate change and global warming, is heavily influenced by regional and worldwide economic trends. The COVID-19 pandemic, which began in China at the end of 2019 and spread to the rest of the world in the first quarter of 2020, caused the global economy and marine transport to decline by 4.1% in 2020. It is proposed in this study to investigate various scenarios by modelling this circumstance that has unexpectedly occurred using decision assistance technologies.
ABSTRACT
Transportation sector is the important sector and consumed the most fossil fuel in the world. Since COVID-19 started in 2019, this sector had become the world connector because every country relies on logistics. The transportation sector does not only deal with the human transportation but also relates to logistics. Research in every country has searched for alternative transportation to replace internal combustion engines using fossil fuel, one of the most prominent choices is fuel cells. Fuel cells can use hydrogen as fuel. Hydrogen can be fed to the fuel cells to provide electric power to drive vehicles, no greenhouse gas emission and no direct combustion required. The fuel cells have been developed widely as the 21st century energy-conservation devices for mobile, stationary, and especially vehicles. The fuel cell electric vehicles using hydrogen as fuel were also called hydrogen fuel cell vehicles or hydrogen electric vehicles. The fuel cells were misconceived by several people that they were batteries, but the fuel cells could provide electric power continuously if their fuel was provided continuously. The batteries could provide electric power as their only capacities, when all ions are released, no power could be provided. Because the fuel cell vehicles play important roles for our future transportation, the overall review for these vehicles is significantly interesting. This overall review can provide general and technical information, variety of readers;vehicle users, manufacturers, and scientists, can perceive and understand the fuel cell vehicles within this review. The readers can realize how important the fuel cell technologies are and support research around the world to drive the fuel cell vehicles to be the leading vehicles in our sustainable developing world. © 2022 Hydrogen Energy Publications LLC

ABSTRACT
The effects of climate change can be seen immediately in ecosystems. Recent events have resulted in a commitment to the Paris Agreement for the reduction of carbon emissions by a significant amount by the year 2030. Rapid urbanisation is taking place to provide room for an increasing number of people's residences. Increasing the size of a city and the number of people living there creates a daily need for consumable resources. In the areas of transportation, supply chains, and the utilisation of renewable energy sources, deliver on pledges that promote the accomplishment of the Sustainable Development Goals established by the United Nations. As a result, the supply chain needs to be handled effectively to meet the requirements of growing cities. Management of the supply chain should be in harmony with the environment;nevertheless, the question of how to manage a sustainable supply chain without having an impact on the environment is still mostly understood. The purpose of this study is to present a conceptual model that may be used to maintain a sustainable supply chain with electric vehicles in such a way that caters to both environmental concerns and human requirements. As part of the continual process of achieving sustainability, interrelationships between the various aspects that are being investigated, comprehended, and applied are provided by the model that was developed. It is self-evident that governmental and international organisations that are concerned with supply-demand side information will benefit from such a model, and these organisations will locate viable solutions in accordance with the model's recommendations. Beneficiaries consist of individuals who are active in the supply chain and are concerned with supply-demand side information. These individuals also need to understand how to effectively manage this information.
ABSTRACT
Although net-zero greenhouse gas emission targets continue to gather burgeoning streams of research, there is a lacuna in current literature on the pathway challenges towards operationalizing decarbonization. The study advanced 2 × 2 matrix of an organizing framework of challenges in accomplishing net-zero emissions targets. Using the global airline industry as an illustrative context, the study provided deep insights on the pivotal industry, institutional, and organizational challenges in the era of COVID-19 such as fleet modernization, over-reliance on fossil fuel, slow progress in the development of hydrogen and electric aircraft, risk of corporate greenwashing, and divergent approaches adopted by airlines. The challenges can be classified into policy-oriented, organization-specific, and external/macro-environment factors. The contributions to theory and practices were identified and examined.

The EU projects reaching net-zero emissions by 2050, thus reducing CO2 emissions is a priority in the European Climate Law published in 2021. The transport sector is the second contributor to CO2, responsible for around 26% of EU greenhouse gasses emissions. In 2020, GHG (greenhouse gas) emissions from transport in the EU have dropped by 12.7% due to the COVID-19 pandemic. As society comes back to normality, vehicles use is increasing again. To reach the emission targets, new vehicles can introduce CO2-reducing eco-innovative technologies. So far, these technologies accepted under WLTP are light-emitting diodes and efficient alternators. Nevertheless, many other technologies have potential as eco-innovations. In the past, eco-innovative technologies have contributed to reducing EU CO2 emissions. In 2018, the fleet of newly registered cars with eco-innovations saved around 11000 tonnes of CO2. An increasing tendency is seen in 2019: 21000 tonnes of CO2 were saved at fleet level. During 2020, new car registrations with eco-innovations were higher, having the potential to save around 40000 tonnes of CO2 at fleet level. Despite their positive impact, their CO2-reducing effect can be diminished when two of these technologies interact with each other. The presence of the lighting system and the alternator lowers the CO2 savings if compared to the summation of the savings of each technology separately. The impact of the interactions of approved eco-innovations can imply a decrease of 9% of the sum of the CO2 savings from each technology considered independent from the other. ©
ABSTRACT
The COVID-19 pandemic has pushed up the green finance for renewable energy development. Private investment has been recognized as a dominant driver of the renewable energy industry, an essential and critical step in averting greenhouse gas emissions. Nonetheless, despite the increasing pace, private investment in green finance for renewable development is still restricted to several developed nations, where it is crucial. Prior studies have offered some understanding of the complexities and challenges that investment confronts in this industry, which remains underexplored in the case of China. This study employs the ARDL-PMG model used to examine the public listed companies in Shanghai and Shenzhen during China's 2010–2020 period. This research adds to the body of knowledge by rigorously examining the variables on FDI in renewable energy production in China and how these effects differ depending on the source of investment. Some of these factors include the adoption of national renewable energy legislation, the supply of foreign public money, and the broader economic environment. The findings indicate that worldwide financial assistance, legislative support policies, feed-in tariffs, and economic stability are potent drivers of green finance for developing renewable energy investment in China. Further, this research explains that the impacts of private sector investment and entrepreneurial contextual factors on expenditure vary depending on the source of finance, emphasizing the importance of dissecting investment spreads to fully comprehend private investment decisions in green finance for renewable development. © 2022
ABSTRACT
OBJECTIVE: Academic and organizational leaders in psychiatry and all other medical fields are negatively impacted by climate change. The COVID-19 pandemic prompted a rapid shift to the use of more telehealth by behavioral health clinicians. The purpose of this study was to estimate the reduction of patients' greenhouse gas emissions during this rapid shift at one academic psychiatry institution. METHODS: The authors extracted data associated with all outpatient visits to all 26 psychiatry clinics from March 16, 2020, to December 31, 2020. Once the patients' travel miles saved by confirmed virtual visits were calculated, the authors used the standard ratio from the US Environmental Protection Agency (EPA) to calculate the total quantity of CO2 that would be emitted if the visits had occurred in person. RESULTS: During the study period, a total of 47,582 outpatient behavioral health visits with 3975 unique patients were completed. The majority of these departmental visits were telehealth (85%), with most of the telehealth visits conducted using real-time audio-video platforms (75.7%). Subtracting emissions from patient technology during telehealth visits from the estimated patient transport values produced a net savings of greenhouse gas emissions of 867,011 kg CO2. This amount is equal to the greenhouse gas emissions from 189 passenger vehicles driven for 1 year according to the EPA. CONCLUSIONS: This study shows that converting in person, face-to-face behavioral health visits to telehealth has the potential to increase both energy efficiency and conservation through a reduction in greenhouse gas emissions due to reduced patient travel. If these values were extrapolated to the total adult US population who have visits for behavioral health reasons, we estimate that conversion to virtual visits could save approximately 830,000 metric tons of CO2 annually. Organizational leaders should consider these societal benefits when making decisions regarding development and support of telehealth.

Food supply chains hold significant embodied carbon emissions that need to be mitigated and neutralized. This study aimed to explore the historical Greenhouse Gas (GHG) emissions associated with household food consumption at a local scale i.e. across the eight English regions and the four nations that comprise the United Kingdom (UK). UK EatWell guidelines were used to explore the potential change in emissions and food costs in a scenario of transitions to healthier diets across the study areas. These emissions were calculated based on food consumption data before the advent of the Covid-pandemic i.e. between the years 2001 and 2018. Spatial data analysis was used to explore if the study areas had any significant correlations with respect to the emissions during the study period. The results displayed a potential reduction in GHG emissions for all study areas in the explored scenario. Further impacts include a reduction in household food costs across a majority of the areas during the study period. However, a consistent trend of significant correlations among the study areas was absent. This study concludes that local or regional policymaking should take precedence over national regulations to achieve healthier diets that are both carbon-neutral and affordable for the households. © 2022 Informa UK Limited, trading as Taylor & Francis Group.
