The hidden costs of the low-emission transition : A Critical Analysis of Lithium Extraction, Green Discourses, and Sweden’s New Giga Battery Factory / Lågemissionsomställningens dolda kostnader : En kritisk analys av litiumutvinning, gröna diskurser och Sveriges nya giga-batterifabrik

Fyrén, Amanda, Nordenswan, Sofia January 2024 (has links)
To reduce anthropogenic greenhouse gas emissions, many European countries are focusing on a low-emission transition by electrifying the transport sector, with special emphasis on electric vehicles (EV). However, this transition requires a large amount of lithium and other critical metals. While the current low-emission transition is portrayed as decreasing climate impact, the transition and its need for metals create new forms of socio-environmental impact. An increasing number of studies are critically examining the effects of the low-emission transition, both nationally and internationally. However, most studies are focused on the Global South with fewer focusing on the effects within and impacts caused by Europe and Scandinavia. Hence, the purpose of this study was to explore the narratives surrounding the low-emission transition, with a primary focus on Sweden and a partial focus on the EU. Additionally, the study aimed to trace the origin of the lithium used in Sweden’s lithium-ion battery production to examine the socio-ecological impacts of its extraction. Using critical discourse analysis, a methodology acknowledging language as a social construct and capable of revealing power dynamics within society, the study found that green imaginaries and techno-centric perspectives are common when discussing the low-emission transition. While specific volumes and origins of imported lithium to Sweden were difficult to obtain, a broader literature review of lithium extraction and its supply chain could infer that the current lithium extraction needed for the Swedish EV battery production, most likely, comes with a broad socio-environmental impact, extending from ecosystem degradation, water scarcity, pollution, and possibly discrimination against indigenous rights. To conclude, the Swedish low-emission transition is despite its green portrayal connected to a hidden but potentially large socio-environmental impact.

Building a Greener Future: Reconstructing the Discourse on Sustainability in the German Construction Sector : How do stakeholders within the German construction sector translate sustainability in their daily practices and to what extent do these practices align with the principles of the Gaia hypothesis?

Meesenburg, David January 2024 (has links)
Sustainability is viewed as a solution to climate change and social unrest, yet the systems we use to understand and implement it often contribute to the very problems they aim to solve. This thesis investigates how stakeholders in the German construction sector integrate sustainability into their daily practices. Using James Lovelock’s concept of Earth as a self- regulating system, the study explores stakeholders’ perceptions of sustainability. Based on qualitative interviews, the research identifies three main themes: certification systems, economic pressures, and the intrinsic connection of stakeholders to Gaia. Findings suggest that while certification systems guide sustainable practices, they are often used due to other motivations than for genuine environmental efforts. Economic pressures further hinder the adoption of sustainable practices, as stakeholders prioritize short-term gains over long-term ecological benefits. However, a strong connection to Gaia and could inspire deeper engagement with sustainability. The thesis concludes that adopting the interconnectedness emphasized by the Gaia hypothesis could lead to more effective and authentic sustainability practices in the construction sector.

Understanding environmental assessment and public participation process challenges among the vulnerable interested and affected parties : five cases studies from rural KwaZulu-Natal.

Mahlangu, Isaiah Mahlolani. January 2008 (has links)
The Public Participation Process (PPP) for Environmental Assessment (EA) is a mandatory procedure to facilitate participation of Interested and Affected Parties (IAAPs) in decision making for proposed development projects. Participation of the vulnerable IAAPs in the PPP is affected by complex challenges. These challenges make it difficult or impossible for Environmental Assessment Practitioners (EAPs) to successfully conduct and complete PPPs. This study investigated the nature and impact of the challenges in the decision making process. The study sought to develop an understanding of the challenges and suggest better approaches. Based on purposive sampling, a case study approach was adopted to analyse five PPP cases conducted in rural KwaZulu-Natal. Five key challenges: lack of EA legislation awareness; imbalanced power relations; negative past experience; threat to environmental autonomy; and poor project planning affected the PPP cases analysed in this study. These challenges emanate from internal and environmental factors. The study argues that internal challenges such as a lack of EA legislation awareness can be managed better during the PPPs. However, external challenges such as imbalanced power relations are usually impossible to resolve during the PPP. The modes of communication play a key role in public participation. Word of mouth is appropriate to facilitate participation of the vulnerable IAAPs. A key finding was the combined impact of the challenges and appropriateness of communication mode determines the PPP outcome, with the challenges being significant determining factor. The study maintains that a good understanding of potential challenges associated with development project sites will enable EAPs to design better and more responsive PPP approaches. To achieve this, the study recommends a Dual Approach Planning Model (DAPM). This approach recommends designing the PPP through preplanning information appraisal and prediction of potential challenges to create awareness about potential challenges. The DAPM argues that this awareness will assist EAPs to better estimate the time and to mobilise tools and resources required to manage the challenges, while focusing on successful completion of the PPP. This approach is also adaptive in nature. / Thesis (M.Env.Dev.)-University of KwaZulu-Natal, Pietermaritzburg, 2008.

Critical review of the quality of environmental authorizations in South Africa / Andrew Brian Caddick

Caddick, Andrew Brian January 2015 (has links)
This dissertation critically reviews the quality of South African environmental authorisations through the application of a methodology adopted from the Lee and Colley (1999) environmental impact assessment (EIA) report review package. The literature review shows that to date limited research has been conducted on the quality of environmental authorisations nationally. Anecdotal evidence suggests that environmental authorisations are of weak quality; hence the development of guidelines on the compilation of environmental authorisations by the Department of Environmental Affairs (DEA). In this dissertation, the quality of the environmental authorisations is critically reviewed against the requirements of the National Environmental Management Act (Act No. 107 of 1998) and departmental guidelines. The research concludes that only 64% of reviewed authorisations are deemed satisfactory, while 36% were unsatisfactory. When the basic assessment report (BAR) and scoping and environmental impact assessment (S&EIA) process authorisations are compared it is concluded that the there is a minimal difference in quality. The BAR achieved a 69% satisfactory rating while the S&EIA process achieved a 61% satisfactory rating. The dissertation concludes by making recommendations to improve the quality of authorisations. / M (Environmental Management), North-West University, Potchefstroom Campus, 2015

A critical evaluation of the extent to which sustainability was considered in the Medupi power station / Melini Hariram

Hariram, Melini January 2015 (has links)
Sustainable development is described by the World Commission on Environment and Development as ―development that meets the needs of present without compromising the ability of future generations to meet their own needs‖. Sustainability assessments are an integrative process and framework for effective integration of social, economic and ecological considerations in significant decision-making processes. Sustainability is incorporated into South African legislation such as the Constitution of the Republic of South Africa (1996), the National Environmental Management Act (Act 107 of 1998), as well as Environmental Impact Assessment (EIA) Regulations. Despite the existence of such legislation, the challenge lies in the effective implementation of the EIA process, which has been identified as a useful tool in striving towards achieving sustainable development. This research uses Gibson‘s eight sustainability principles and Gaudreau and Gibson‘s sub-criteria to develop a case specific set of sustainability criteria for coal fired power stations in South Africa. The energy generation sector is a major source of social and environmental impacts. Coal power stations contribute to environmental degradation such as reduced air, water and land quality. This industrial process impacts on the environment and therefore needs to strive towards sustainable development by considering these criteria during the EIA process. The set of case specific sustainability criteria for power stations was then used to evaluate the EIA developed for Medupi Power Station in South Africa in order to assess, the extent to which sustainability was considered in the EIA process. The key finding is that sustainability is incorporated into South African legislation hence no change in legislation is required. Despite the existence of legislation, the challenge lies in the fact that is it not always effectively implemented. The EIA process is seen as a tool that can effectively deliver sustainability outcomes. However this process is not effectively utilised. In order for the EIA to consider sustainability the focus needs to be on the following criteria: Intragenerational Equity; Precaution and Adaptation for Resilience; as well as Immediate and Long term Integration, as these were recognised as weaknesses after the evaluation process. The recommendation is also to develop a set of case specific sustainability criteria for other large industries that have significant environmental impacts. / MSc (Environmental Management), North-West University, Potchefstroom Campus, 2015

Public participation in environmental impact assessment : an effective tool for sustainable development a South African perspective (Gautrain)

Aregbeshola, Maryam Titilayo 03 1900 (has links)
The need for public participation in the development of policies, programmes or actions has been widely accepted by both government and private sectors because of the benefits of such involvement. Involving the public in the development of any policy, programme or action is, however, a daunting task. Public involvement in the development of a policy or action often leads to protest, legal litigation, criticism and delay in carrying out the project. The main objectives of this research are to examine the process of public participation in the Gautrain project and to interrogate how public involvement in the decision-making processes of environmental concerns can be improved. A quantitative study was conducted to describe and explore the process of public participation in the Gautrain environmental impact assessment procedure. The purposive sampling method was used. Thereafter, the data generated was analysed using statistical tools such as charts, tables and the Wilcoxon Mann Whitney U test to examine the similarities and differences in the response patterns of the public and the project proponent. Cronbach alpha statistical methodology was also used to test the reliability of the measurement. The findings are discussed in relation to the objectives of the study and research hypotheses. The results indicate that (1) the public were not involved early enough during the project planning and design phases; (2) adequate information was not provided to the public; and (3) public input does not have much impact on decisionmaking processes. The study does, however, indicate that the process has enhanced the participants’ learning and that the process of participation has improved in recent time as compared to the 2002-2003 periods. The study concludes by providing relevant solutions and recommendations. / Environmental Sciences / M. Sc. (Environmental Management)
