Today, ships navigating all around the world are not allowed to emit SOx more than 0.5%. Same regulation for nitrogen has already come into force. More and more nations are becoming aware and concerned about the negative effects of climate change, whereas many countries are already feeling the effects of harmful greenhouse gas emissions. Therefore, the world’s fleet needs a new fuel types, which are alternative to conventional petroleum-based ship fuels. Benefits such as low sulphur standards accompany all alternative fuel options. As will be discussed further in Section 2, there are challenges and limitations associated with CO2 emissions along with benefits. The review of the literature and field shows that the impact of these current choices on the management and environments is still not bright enough, although each alternative has consisted entirely different effects in their body and each alternative pose specific risks to the environment, crew, management and port states. This chapter gives a review on the impact of each alternative fuels on the environment. In addition, the chapter touches upon handling of risks associated with alternative fuels and technologies.

Wind is increasingly used as a renewable energy all around the world. Although wind turbines help reduce greenhouse gas emissions, the costs to wildlife cannot be overlooked. To date, monitoring programs and research have mainly focused on the impact of wind farms on birds but negative effects on bats have also reported. Here we compile information related to European free–tailed bat deaths at wind farms in southern Spain. In a world where the demand for renewable energy is rising we highlight the need to better understand and prevent bat fatalities.

Background: Environmental deterioration is the alarming situation that results from rapid urbanization and development. The rising temperature and climate volatility are accounted for by the massive carbon dioxide (CO2) emissions. The research on climate-change mitigation is trying to curtail the situations before they become irreversible and unmanageable. This study explores the role of institutions in mitigating climate change by moderating the impact of environmental quality on climate change risk. Methodology: Global data sets have been collected from world big data depositories like the World Economic Forum (WEF), the World Development Indicators (WDI), and the International Country Risk Guide (ICRG). Countries that are listed in WEF were used as the sample of the study. An analysis was based on 114 countries that are based on the availability of data. For estimation, descriptive statistics, correlation analysis, change effects, and a Panel Feasible Generalized Least Squares (FGLS) model were used for estimating the results. Results: The global assessment indicates that CO2 emissions increase the climate risk, but its impact can be reduced by increasing the quality of institutions. Additionally, an increase in renewable energy consumption and economic growth reduces the climate risk. Implications: It is an instrumental study that empirically investigated the role of institutions in reducing climate risk by moderating CO2 emissions. The results of this study will help policymakers to formulate policies regarding environmental protection.

The Impact

While various researchers and practitioners agree that it will be hard to restructure our current global and local systems to adapt to and mitigate climate change, there is unsurprisingly great disagreement in how and if this can be accomplished and on what level(s), or if this is even what needs to be accomplished. These conversations have continued with the introduction of the “Anthropocene.” The dominant interpretation of the concept poses several solutions, one being national government restructuring to support environmental efforts and encouraging behavioral change. To join conversations that critically evaluate the conceptualization and implications of the Anthropocene with the world-systems perspective, we consider how the effectiveness of national environmental governance in reducing CO2 emissions varies by a country’s position in the global hierarchy. Using two-way fixed effects regression, this article tests how one aspect of this environmental governance, environmentally related taxes as a percentage of total tax revenue impacts CO2 emissions for 75 countries from 2000 to 2011. Given inequities in the global division of labor, which reinforce the dominance of higher-income countries and the exploitation of lower-income countries, we expect the effectiveness of environmental governance to vary tremendously by global position. Our results support the idea that the impact of environmental governance on CO2 emissions varies across countries at different income levels in the world-system, and this is due to external constraints. Such external influence is unsurprisingly neglected in dominant interpretations of the Anthropocene. In line with previous critical research, we argue that these external constraints undermine climate change solutions because they fail to address mutually reinforcing global, political, economic, and environmental inequalities.

Among the alternative fuels existing for spark-ignition engines, ethanol is considered worldwide as an important renewable fuel when mixed with pure gasoline because of its favorable physicochemical properties. An in-depth and updated investigation on the issue of CO and HC engine out emissions related to use of ethanol/gasoline fuels in spark-ignition engines is therefore necessary. Starting from our experimental studies on engine out emissions of a last generation spark-ignition engine fueled with ethanol/gasoline fuels, the aim of this new investigation is to offer a complete literature review on the present state of ethanol combustion in last generation spark-ignition engines under real working conditions to clarify the possible change in CO and HC emissions. In the first section of this paper, a comparison between physicochemical properties of ethanol and gasoline is examined to assess the practicability of using ethanol as an alternative fuel for spark-ignition engines and to investigate the effect on engine out emissions and combustion efficiency. In the next section, this article focuses on the impact of ethanol/gasoline fuels on CO and HC formation. Many studies related to combustion characteristics and exhaust emissions in spark-ignition engines fueled with ethanol/gasoline fuels are thus discussed in detail. Most of these experimental investigations conclude that the addition of ethanol with gasoline fuel mixtures can really decrease the CO and HC exhaust emissions of last generation spark-ignition engines in several operating conditions.

Abstract This workshop is dedicated on SDGs in the focus of environmental and health issues, as very important and actual topic. One of the characteristics of today's societies is the significant availability of modern technologies. Over 5 billion (about 67%) people have a cellphone today. More than 4.5 billion people worldwide use the Internet, close to 60% of the total population. At the same time, one third of the people in the world does not have access to safe drinking water and half of the population does not have access to safe sanitation. The WHO at UN warns of severe inequalities in access to water and hygiene. Air, essential to life, is a leading risk due to ubiquitous pollution and contributes to the global disease burden (7 million deaths per year). Air pollution is a consequence of traffic and industry, but also of demographic trends and other human activities. Food availability reflects global inequality, famine eradication being one of the SDGs. The WHO warns of the urgency. As technology progresses, social inequality grows, the gap widens, and the environment continues to suffer. Furthermore, the social environment in societies is “ruffled” and does not appear to be beneficial toward well-being. New inequalities are emerging in the availability of technology, climate change, education. The achievement reports on the Sustainable Development Goals (SDGs), also point out to the need of reviewing individual indicators. According to the Sustainable Development Agenda, one of the goals is to reduce inequalities, and environmental health is faced by several specific goals. The Global Burden of Disease is the most comprehensive effort to date to measure epidemiological levels and trends worldwide. It is the product of a global research collaborative and quantifies the impact of hundreds of diseases, injuries, and risk factors in countries around the world. This workshop will also discuss Urban Health as a Complex System in the light of SDGs. Climate Change, Public Health impacts and the role of the new digital technologies is also important topic which is contributing to SDG3, improving health, to SDG4, allowing to provide distance health education at relatively low cost and to SDG 13, by reducing the CO2 footprint. Community Engagement can both empower vulnerable populations (so reducing inequalities) and identify the prior environmental issues to be addressed. The aim was to search for public health programs using Community Engagement tools in healthy environment building towards achievement of SDGs. Key messages Health professionals are involved in the overall process of transformation necessary to achieve the SDGs. Health professionals should be proactive and contribute to the transformation leading to better health for the environment, and thus for the human population.

The Coronavirus pandemic has caused negative effects across the globe; mortality and morbidity being the main impact. After WHO, termed the disease a pandemic in March 2020, they gave in health guidelines to follow to control the spread of the disease. The health industry, academia, and different governments are united to develop and test various vaccines at an unprecedented speed to combat the pandemic fully and bring the world back to its feet. Some of the vaccines developed include Pfizer, Moderna, and AstraZeneca. However, just like other viruses, the SAR-CoV-2 virus keeps changing through mutation, as various variants, different from the first one are emerging. Evidence shows that the three new variants; UK, Brazil, and South Africa are more severe in terms of transmissibility, disease severity, evading of the immune response, and reducing the ability to neutralized antibodies, compared to the original coronavirus. With such knowledge of the existence of different strains, the arises concerns on whether the already available vaccines are effective enough in preventing the new COVID-19 strains. Studies are still underdeveloped to learn more on the virologic, epidemiologic, and clinical characteristics of the ever-emerging variants. This research, through a systemic review of literature, seeks to find out whether the variants of SAR-CoV-2 have an impact on the efficacy of various vaccines developed in fighting the disease and the entire body’s immune response.

<p><b>Abstract </b></p> <p>While the pedagogical benefits of fieldtrips have long been recognised our ever increasing understanding of the impacts of flying on climate change is presenting educators with a poignant dilemma; the many benefits long associated with international fieldtrips are at odds with the world community’s needs in limiting/halting climatic change. In response, the paper presents the concept of a VR-based virtual fieldtrip as an innovative and carbon-sensitive type of (educational) travel. The paper not only makes the case for virtual fieldtrips as a meaningful learning tool but also explores both the virtual fieldtrip’s impact on Greenhouse Gas emissions and climate change-related learning. On both accounts the initial findings in this paper are very encouraging. More in-depth research is now required to not only develop a deeper understanding of the full breadth of benefits, but also of the diverse weaknesses presented by virtual fieldtrips and how to negotiate them.</p>

In modern conditions, issues related to the effectiveness of the regulation of the oil industry by the state are becoming increasingly important. In January 2018, the World Economic Forum was held in Davos, which, in particular, noted the impact of the growth of protectionist trends in the global trade in hydrocarbons, and the impact of climate change on the planet on the export of hydrocarbons. As a result of the forum, the key ways of adjusting the policy of states in the relevant area were identified. At the same time, a significant number of states are already seeing the process of changing state regulation of the industry. In this article, the authors analyzed the systems of state regulation of the oil industry in different countries, and also gave assessments of the possibility of integrating new mechanisms into the system of sectoral management in Russia in the conditions of post-covid reality

Climate change is one of the greatest threats to human beings, and agriculture is one of the fields that is most negatively affected by climate change. Farmers around the world and global food supply chains are impacted by the more extreme weather phenomena and increased damage of diseases and pests caused by climate change. Today, almost all agricultural enterprises and farms consider climate change a serious long-term risk for their production. Agricultural land systems can produce significant greenhouse gases (GHGs) by the conversion of forests to crop- and animal lands, and also through the weak management of crops and livestock. Around the world, cultivation and cattle production accounts for 25% of global GHG emissions (Javeline, ‎2014). However, under suitable conditions, agriculture can create environmental conditions that can help minimize pollution and the negative effects of climate change including carbon absorption by green plants in forests, and fields for watershed protection and biodiversity conservation. Sustainable agriculture helps farmers to adapt, maintain, and improve productivity without applying harmful techniques. In turn, this allows farms to manage and mitigate climate-related risks in their supply chains. The Sustainable Agriculture Network (SAN) has found new ways to incorporate smart climate cultivation methods into all farming practices to help farms and enterprises carry out agriculture sustainably.
