Climate Change Mitigation Issues Research Articles

Comprehensive survey of artificial intelligence techniques and strategies for climate change mitigation

With the galloping progress of the changing climates all around the world, Machine Learning (ML) approaches have been prevalently studied in many types of research in this area. ML is a robust tool for acquiring perspectives from data. In this paper, we elaborate on climate change mitigation issues and ML approaches leveraged to solve these issues and aid in the improvement and function of sustainable energy systems. ML has been employed in multiple applications and many scopes of climate subjects such as ecosystems, agriculture, buildings and cities, industry, and transportation. So, a Systematic Literature Review (SLR) is applied to explore and evaluate findings from related research. In this paper, we propose a novel taxonomy of Deep Learning (DL) method applications for climate change mitigation, a comprehensive analysis that has not been conducted before. We evaluated these methods based on critical parameters such as accuracy, scalability, and interpretability and quantitatively compared their results. This analysis provides new insights into the effectiveness and reliability of DL methods in addressing climate change challenges. We classified climate change ML methods into six key customizable groups: ecosystems, industry, buildings and cities, transportation, agriculture, and hybrid applications. Afterward, state-of-the-art research on ML mechanisms and applications for climate change mitigation issues has been highlighted. In addition, many problems and issues related to ML implementation for climate change have been mapped, which are predicted to stimulate more researchers to manage the future disastrous effects of climate change. Based on the findings, most of the papers utilized Python as the most common simulation environment 38.5 % of the time. In addition, most of the methods were analyzed and evaluated in terms of some parameters, namely accuracy, latency, adaptability, and scalability, respectively. Lastly, classification is the most frequent ML task within climate change mitigation, accounting for 40 % of the total. Furthermore, Convolutional Neural Networks (CNNs) are the most widely utilized approach for a variety of applications.

Анализ выбросов парниковых газов стран BRICS и пути сокращения выбросов на железнодорожном транспорте

Purpose: To analyze greenhouse gas emissions from the BRICS countries, as well as ways to reduce emissions from rail transport. Methods: The contribution of the BRICS countries to global greenhouse gas emissions based on an array of statistical data for the period from 1990 to 2019 has been estimated. The value of CO2 emissions per unit of energy produced in the BRICS countries from 1965 to 2021, as well as the sources of CO2 emissions, have been determined. Results: It is shown that the most effective way to combat climate change is to directly reduce emissions. In general, the emissions of the railway industry depend on the level of electrification. However, when assessing not only direct but also indirect emissions, the energy source and its carbon footprint become of primary importance. The development of intermodal transportation in BRICS countries is significant because these routes have the potential to reduce emissions. Carbon regulation leads to a redistribution in the sphere of international freight transportation among BRICS countries. Competitive advantages are increasingly evident in the railway transportation sector. However, this effect depends on the measures taken to adapt to changes in the transportation market by other modes of transportation. Practical significance: Ways to improve the sustainability of transport infrastructure have been formulated. The lowcarbon transport industry in the BRICS countries can be seen as an important component in reducing gross greenhouse gas emissions given the current high level of reliance on fossil carbon fuels and the inertia driven by the long life of fossil fuel infrastructure. Without the use of negative emission technologies, the required costs for reducing greenhouse gas emissions can be 40 % higher than with the use of negative emission technologies. As part of the reduction of greenhouse gas emissions by railway transport facilities in the BRICS countries, the following measures can be implemented: direct reduction of greenhouse gas emissions; introduction and implementation of technologies for negative emissions at railway transport facilities, taking into account their geospatial distribution and their specific characteristics; attracting investments and ensuring access to more affordable financing for these projects; integration of climate change mitigation issues into the strategies of transportation companies; further electrification in transportation and transitioning to alternative fuel sources; utilization of digital technologies to optimize transportation systems and reduce the environmental impact of the railway industry.

Climate change-related knowledge and attitudes among a sample of the general population in Egypt.

Identifying the public awareness and risk perception regarding climate change, are fundamental preliminary steps in determining gaps and paving the way for awareness campaigns that address climate change causes and counteraction mitigation measures. However, few studies were conducted in Egypt; thus, the researchers conducted the current cross-sectional study among a sample of the Egyptian population to identify general knowledge and perception about climate change and its effects, as well as attitudes toward mitigation measures. An exploratory population-based electronic-open survey, was conducted among 527 members of the general population between January and April 2022, using a convenience sampling technique. A pre-tested 2-page (screen) electronic included three sections: sociodemographic characteristics, global warming/climate change-related knowledge, and attitude toward climate change mitigation. The average global warming knowledge score was 12 ± 3. More than 70% (71.1%) of the participants were knowledgeable (percentage score >70%). Approximately half of the enrolled participants (48.2%) agreed that everyone is vulnerable to the effects of global warming/climate change. More than three-quarters (78.3%) of the participants agreed that carbon emissions from vehicles and industrial methane emissions were the first factors that contributed to climate change, followed by the ozone holes (731%). Global warming/climate change-related knowledge was statistically higher in participants aged of >30 years, married participants, urban residents, highly educated individuals, and employed individuals (p-value ≤ 0.05). Approximately 80% of the participants agreed that responding to the questionnaire drew their attention to the topic of climate change and its effects. More than two-thirds of those polled agreed that increasing public transportation use could help mitigate the effects of climate change/global warming, followed by the materials used and the direction of construction. More than two-thirds of the participants were knowledgeable regarding climate change. Social media and the internet were the main sources of information. However, participants need to get the information in a different way that could help in changing their attitude positively toward the issue of climate change mitigation. The current study recommends the need for various initiatives that work should be launched.

On-Farm Relationships Between Agricultural Practices and Annual Changes in Organic Carbon Content at a Regional Scale

Both soil quality degradation and climate change mitigation issues emphasize the need to increase, or at least stabilize, the topsoil organic carbon content (wt%) in arable land. This on-farm study aimed at measuring the impact of agricultural practices on changes in soil organic carbon (SOC) content over 10 years. A total of 120 fields belonging to 120 farms representative of the cropping systems and soil properties in Western Switzerland (Lake Geneva region) was randomly selected. The field 0–20 cm topsoil was sampled at a 10-years interval, and the corresponding cropping practices were gathered using farmer’s interviews and the mandatory records of yearly practices at field level in Swiss-farms. Only 1) organic matter inputs and 2) cover-crop intensity were significantly correlated to SOC increase while 3) the soil tillage intensity and 4) the soil saturation in carbon expressed as a SOC to clay content ratio were correlated to SOC decrease. Among others, temporary meadows were not correlated to changes in SOC content mainly due to increased tillage and decreased cover-crops between meadows. Organic farming did not correlate either with SOC changes due to the large tillage intensity applied for weed control. The observed SOC content changes ranged from −56‰ to +74‰ and were well explained by a linear regression model with additive effect of the four identified SOC change factors. The additivity of these factors means that farmers can emphasize the methods of their choice when regenerating their soils. This study advocates that strict no-till is not required at low carbon saturation level (small SOC:Clay ratio). However, as carbon saturation increases, conservation tillage and then no-till practices become necessary to further increase SOC contents. These findings are in accordance with previous studies showing that since 2015 SOC is increasing at more than +4‰ on average in the region and provide practical insights to further manage the transition of farming systems towards soil regeneration.

Lifelines and Sinking Ships: Investor Reactions to Divestments During Industry Change

Navigating a period of industry change can be challenging for incumbent firms. In this paper, we consider an important barrier to adaptation – technological commitment – and analyze how investors react to a firm’s departure from its core position. We argue that, over time, cost efficiency concerns and shareholder advocacy potentially moderate the negative impact of commitment to a fading technology on market valuation. Building on the industry change and corporate divestment literatures, we argue that it will be increasingly difficult for incumbents with greater technological commitment to exit from this position even as the transition becomes more inevitable, unless investors formally pressure the firm to do so. We find support for our arguments from an event study of announcements of coal plant retirements by U.S. public electric utilities from 2007 to 2019. Our results contribute to understanding challenges with incumbent adaptation to environmental disruptions, as well as the urgent issue of climate change mitigation.

The alternative energy utilization and common regional trade outlook in EU-27: Evidence from common correlated effects

The role of low-carbon energy and trade on the environment has drawn several studies that have looked at issues from different perspectives, thus yielding differing conclusions. Considering the current emphasis on the COP25 conference and the commitment to cut down carbon emissions level, this study also draws strength from the United Nations Sustainable development Goals (UNSDGs) that comprises of positive strides for access to clean and responsible energy consumption (SDGs 7, 12) and climate change mitigation issues (SDG-13). To this end, this study is a timely outlook that underpins the case of the European Union (EU) countries as well as the root cause of anthropogenic activities on clean trajectory of global environment. Hence, we investigate the connection between alternative and sustainable energy source, trade, income and emissions in 27 selected European Union economies by utilizing data covering the period 1990–2017 on an annual frequency. We used second-generation panel model estimators to analyze the relationship between the variables in the long-run. Specifically, the long run results from the MG (Mean Group), AMG (Augmented Mean Group), and CCEMG (Common Correlated Effects Mean Group) estimators reveal that sustainable and alternative energy sources have a negative significant impact on pollutant emissions while trade and income have a positive impact on carbon emissions except that the impact of trade is insignificant. Although the positive impact of openness in trade on carbon emission is insignificant, the positive impact suggests that the free-trade policy that is currently in place in the EU should further incorporate sustainable development goals (SDGs) to avoid the outsourcing of carbon emissions among the member countries. Causality tests reveal a feedback hypothesis between renewable energy, income, trade, and carbon emanations. The investigation proposes expanded utilization of sustainable power source to mitigate carbon emissions in the European Union.

The Right to Seek Asylum of ‘Climate Refugees’

Although the issue of climate change mitigation and adaptation is fortunately evermore widely discussed, the problems facing ‘climate refugees’ only appears sporadically in the discussions adding to the current confusion. Taking recent and forecasted trends into account, the UN declares that states have serious moral obligations to provide humanitarian protection to all those displaced. The question which the international community and international lawyers face is whether states have more than just a moral obligation to provide protection. In this paper I will assess whether or not there are any roots in the various sources of international law – such as conventional law, customary international law, or the fundamental principles of international law – for the legal definition of ‘climate refugees’.

Climate Change Mitigation Policies Targeting Households and Addressing Energy Poverty in European Union

Climate change mitigation measures linked to households’ energy consumption have huge greenhouse gases (GHG) emission reduction potential and positive impact on energy poverty reduction. However, measures such as renovation of residential buildings or installation of micro generation technologies based on renewable energy sources have not realized their full energy saving and GHG emission reduction potentials, due to the energy efficiency paradox and other barriers. These climate change mitigation policies targeting the households’ sector can deliver extra benefits such as energy poverty reduction and implementation of the energy justice principle; therefore, they require more attention of scholars and policy makers. The aim of this paper is to analyze the energy poverty and climate change mitigation issues in EU households based on a systematic literature review, and to provide future research paths and policy recommendations. Based on the systematic literature review, this paper develops an integrated framework for addressing energy poverty, just carbon free energy transition and climate change mitigation issues in the EU. Additionally, we argue that more targeted climate change policies and measures are necessary in the light of the shortcomings of current measures to reduce energy poverty and realize climate change mitigation potential linked to energy consumption in households.

External Pressures or Internal Governance - What Determines the Extent of Corporate Responses to Climate Change?

To prevent adverse effects from climate change, it is vital to involve the private sector in mitigation efforts. So far, however, research has insufficiently addressed the determinants of corporate action in specific industries. Our paper aims at bridging this gap by empirically analyzing the global automotive industry's response to climate change mitigation issues. We use publicly available information from 105 sector leaders to investigate the role of external institutional pressures and intra‐organizational governance in the extent of corporate action. Based on a multiple regression analysis, we find that organizational involvement and the integration of climate change into risk management exhibit the greatest influence. Moreover, companies with business activities that necessitate interaction with the end consumer tend to be most active. Our analysis furthermore indicates that neither the stringency of a firm's home country's climate policy regime nor the degree of internationalization is associated with a higher implementation level of response strategies. © 2017 The Authors.

Cooperation in the climate change mitigation in forestry and nature protection at different levels of governance

Climate change mitigation is the responsibility of many institutions and organizations in Serbia at different levels of governance, and therefore, it is necessary for them to cooperate with each other and with other stakeholders. The aim of the paper is to determine the existence of cooperation in climate change mitigation in forestry and nature protection at different levels of governance in Serbia. Primary data were collected in the period November 2016 - March 2017. Thirty-four interviews were conducted with representatives of institutions and organizations in forestry and nature protection at the national, regional and local level of governance, dealing with issues related to climate change mitigation. Three questionnaires were used (for each level separately), composed of five question groups. Various forms of cooperation have been established at different levels of governance, through exchange of information and education, machinery and equipment exchange, financial cooperation, etc. However, there is no systemically organized reporting process between institutions on climate change issues at the national level, nor at the regional level. At the local level, there is a partially established system of cooperation between the national level and local self-government, but it is not exclusively related to the issue of climate change mitigation.

Could Cohesion Policy push EU climate efforts?

ABSTRACTThe main purpose of this article is to evaluate the extent to which the Cohesion Policy of the EU contributes to its climate change mitigation effort. While climate change mitigation and the EU Cohesion Policy have been both thoroughly studied theoretically, the novelty of the present article lies in an analysis of their mutual relationship. Also, a unique feature of this research is an analysis of the contribution of the Cohesion Policy to climate change mitigation over a period of 20 years, including a comparison of the three last programming periods (2000–2006, 2007–2013 and 2014–2020). The results of this research suggest that, while the beginning of the new millennium saw the Cohesion Policy neglecting the issue of climate change mitigation, the current programming period (2014–2020) placed it among its key priorities. This conclusion is supported by a comprehensive set of data on five selected indicators. This article also displays the results against the perspective of the overall climate change mitigation objectives of the EU.POLICY RELEVANCEThe present article shows how a policy, which used to be considered rather distant from climate change, progressively adopted climate change mitigation as one of its principal objectives. As such, it provides a practical guidance on the integration of climate change mitigation in other policy areas, which may be applied not only in a supranational organisation but also on a national, regional or local level.

Climate change mitigation in China

Climate change mitigation issues including China’s carbon emission status, the mitigation potential and cost in different sectors, the target of 40%–45% reduction of emission intensity of GDP in 2020 compared with the 2005 level, and conditions and uncertainties of the carbon emission peak are analyzed and assessed in the Third China National Climate Change Assessment Report and summarized in this paper. Economic structure adjustment has played and is expected to continue to play important role for carbon mitigation. Development of nuclear and renewable power would contribute to around 2 billion tons and 3.7 billion tons carbon reductions by 2020 and 2030 respectively. Key energy saving and low carbon technologies in the end-use sectors such as industry, transportation and building are listed and assessed. The mitigation potential and cost curve for steel is provided as an example to show that a large amount of carbon emissions could be reduced with minus mitigation cost partly resulting to energy saved. For industry process, carbon mitigation potentials would be around 420 million tons and 770 million tons by 2020 and 2030 respectively. Carbon mitigation potentials from LULUCF (Land use, land use change and forestry) are still uncertain and needed further research. For the assessment of 45% carbon intensity reduction target in 2020, it is concluded that economic structure adjustment, energy efficiency improvement, development of non-fossil energy, building and transportation would contribute to 33.4%, 28.5%, 20.4% and 17.3% of the total reductions. Assuming GDP growth rate as 6%–7% during 2010–2030, energy intensity reduction rate as 15% during 2015–2020, 14% during 2020–2025, and 13% during 2025–2030, the total primary energy consumption would be around 6 billion tons. To control coal use to less than 50% of the total primary energy consumption, while increasing the share of nature gas to over 10%, and the share of new and renewable energy to 20% or higher, carbon emissions would peak around 2030 at 11 to 12 billion tons. Finally, Climate change mitigation strategies to facilitate the achievement of China’s carbon emission peak target are proposed. It’s also suggested that measures are needed to accelerate the economy restructuring and development modes shift, to control the growth rate of total energy demand, to maintain a sustainable energy system with the new and renewable energy as its main components, and to achieve the carbon emission peak target by sector and region.

Exploring the current status and key determinants of corporate disclosure on climate change: Evidence from the Greek business sector

An increasing number of large corporations around the world engage in accounting for and reporting on their plans and measures towards climate change mitigation, as part of their environmental responsibility agenda. Using a disclosure index, this study contributes to the discussion of enhancing climate change corporate disclosures and informs the limited research assessing such information provision by companies operating in countries of the Southeastern European region. It explores the status of the disclosure practices of the largest 100 firms operating in Greece with respect to the pivotal issue of climate change mitigation and sheds light on determinants that drive domestic companies to publicly disclose such information. The analysis suggests that only a small group of leading Greek companies appears to endorse a climate change discourse as an instrument of empowering stakeholders’ decision-making. Relying on ordered logit regression specifications, we find that subscription to externally-developed voluntary initiatives, international presence well as operating in environmentally sensitive sectors, are significant variables that positively affect climate change disclosure. In contrast, size has a positive yet negligible effect while sector, profitability and type of ownership seem to have no significant influence.

Communicating climate change for adaptation in rural communities: a Pacific study

The academic literature on climate change communications is growing. However, the majority of this literature focuses on the issue of climate change mitigation in a developed country context, and there is little published material regarding communication in a developing country and adaptation context. Similarly, despite community-based approaches to climate change adaptation and disaster risk reduction increasing in the Pacific Islands region, there is very limited guidance on how to effectively communicate climate change in a way that enhances people’s resilience. This paper documents the experiences of organisations, including local and international non-government and faith-based organisations, governments, regional technical organisations and donor agencies in communicating climate change for adaptation in the Pacific region. Three key climate change communication challenges are highlighted and suggestions made for overcoming them based on results from interviews, a focus group discussion and an online forum. Finally, recommendations are made for good practice guidance in climate change communication that is empowering and culturally relevant.

Climate change adaptation and EIA studies in Kenya

PurposeThe paper is an excerpt from a bigger study with an overall aim of examining the extent to which climate change adaptation has been integrated in the EIA studies undertaken in Kenya since the process inception in 2000. The purpose was to establish whether adequate attention is given to the issue of climate change mitigation as major challenge in the world during the 21st century.Design/methodology/approachThe research design is based on qualitative research involving a review of EIA reports approved by the national environmental authority and also based on key informant consultations with licensed EIA experts in the country. Thereafter, the findings were analyzed through standard statistical procedures.FindingsThe findings showed that climate change integration in all the reviewed EIA reports was mainly restricted to mere consideration of historical climate change information in the project areas and totally weak in terms of climate change prediction scenarios and their likely impacts on the proposed development projects. However, consultations with most EIA practitioners indicated that integration of climate change adaptive capabilities into the EIA process was a relevant issue but admitted that the implementation modalities were unclear.Originality/valueThe study is the first in evaluating the level of integration for climate change in EIA studies in Kenya and the findings will inform EIA implementation in the country. It also forms a good basis for comparative studies with EIA studies in other countries of the world.

Mining the internet for linguistic and social data: An analysis of ‘carbon compounds’ in Web feeds

The potential of the Web for applied linguistic research is being increasingly recognized. As the internet is a particularly valuable source of data on recent changes in meaning, Mautner (2005b) made a plea for more discourse analysts to work with Web-based texts in order to study important social developments. Taking up this suggestion, this article introduces an approach based on the analysis of recent updates to Web-based sources. A special purpose corpus, compiled from Web feeds containing so-called lexical ‘carbon compounds’, such as, for example, carbon credit, carbon diet, carbon sinner, is studied with corpus linguistic tools to explore the online dimension of the interpretative struggle around the issue of climate change mitigation. The analysis reveals semantic associations surrounding the compounds and highlights connotational differences that signal both support and criticism of the climate mitigation initiatives proposed by policy makers and environmentalists.

Analysis of possible geological storage of CO2 and nuclear waste in Lithuania

Lithuania is currently dealing with two major problems in energy sector: final closure of Ignalina Nuclear Power plant (Ignalina NPP) in the end of 2009 and nuclear waste disposal and climate change mitigation issues having in mind replacement of nuclear capacities with fossil one and anticipated increase in GHG emissions. Lithuania has two options: to construct new nuclear power plant also taking into account nuclear waste disposal issue or to burn fossil fuel and to apply carbon capture and storage (CCS) for GHG emission reduction. These two options need to be investigated in Lithuania based on various studies conducted in Lithuania and abroad dealing with geological carbon storage and nuclear waste disposal potentials. There are no long-lived nuclear waste geological storage capacities in Lithuania and there is no pilot project on CCS developed in Lithuania. The aim of the article is to analyse and compare geological carbon and nuclear waste storage opportunities in Lithuania and to assess nuclear and carbon capture and storage technologies in terms of costs.
