Assessing future scenarios and absolute sustainability targets with environmentally extended input-output analysis

Kuokkanen, Senja Karoliina January 2017 (has links)
In this master’s thesis project, future scenarios for year 2050 were constructed for Denmark, Finland and Sweden using an environmentally extended input-output analysis (EEIOA). Scenarios were constructed based on national sustainability targets. A case-specific five stage modeling approach was developed. Approach consists of changes in input-output tables for Electricity grid, Fossil primary energy, Industry sectors, Transport and Allocation of fossil fuel replacements. To represent business-as-usual development, EEIO tables for 2009 were used as reference and baseline scenarios. Constructed scenario models resulted in substantial CO2 emission reductions compared to baseline scenario. In scenario results for Denmark, emissions reduced 98.17 %, in Finland 81.41 % and in Sweden 77.90 %. Furthermore, based on Planetary Boundary framework, greenhouse gas emission carrying capacities were estimated in sectoral level for 2050. Carrying capacities for year 2050 for Denmark, Finland and Sweden were 9909.99 kton CO2-eq, 9049.42 kton CO2-eq and 18691.96 kton CO2-eq, respectively. Compared to radically reduced emissions in scenario results, Denmark and Sweden reached emission levels below estimated national carrying capacities. For Finland, carrying capacity level was exceeded by 2437.77 ktons. EEIOA was found to be an efficient tool for constructing and analyzing explorative long-term scenarios. In addition, it is possible to integrate absolute sustainability thresholds to EEIOA. Scenario results indicate that implementation of the existing national sustainability targets would lead to radical emission reductions in Denmark, Finland and Sweden by 2050 compared to business-as-usual development. Based on the scenario results, transport and industry sectors were identified as the emission hotspot sectors in 2050. EEIOA is a noteworthy method for decision-support for assessing sustainability strategies. With EEIOA, it is possible to allocate and study national sustainability targets on a sectoral level, and that way potentially substantially increase the effectiveness and implementation of defined sustainability targets. However, further research on modeling dynamics, data quality and underlined uncertainties are needed before studied approaches can develop into decision-support tools.

Not All Emissions Are Created Equal: A Multidimensional Approach to Examining Human Drivers of Climate Change

Huang, Xiaorui January 2022 (has links)
Thesis advisor: Andrew Jorgenson / Global climate change is among the greatest crises facing humanity in the 21st century. Mitigating the impacts of climate change requires a substantial reduction in global greenhouse gas emissions by 2030. Despite the urgency, climate actions are lacking in many nations. A rich body of cross-national research on human drivers of emissions is devoted to identifying effective leverage points for emission abatement, which primarily focuses on aggregate emission measures such as production-based accounts and consumption-based accounts. However, a nation’s carbon-emitting activities are not monolithic, but can instead be classified into distinct components based on important characteristics such as the supply chain stage to which they belong. These emission components likely have heterogeneous relationships with certain anthropogenic drivers or mitigation measures. Yet, analyses using aggregate emission measures are unable to detect such heterogeneity or inform the unique strategy that might be required to effectively mitigate each emission component. I address this gap using the three empirical chapters of this dissertation. In the first empirical chapter, I propose an analytical framework of Multidimensional Emissions Profile (MEP), which situates nations’ contributions to global greenhouse gas emissions into four distinct components: (1) emissions generated by domestic-oriented supply chain activities; (2) emissions embodied in imports; (3) emissions embodied in exports; and (4) direct emissions of end user activities. I then apply the MEP framework to analyze the relationships between national affluence and the four emission components for 34 high-income nations. I find that as these nations grow wealthier, affluence is increasingly decoupled from direct emissions of end user activities but remains positively associated with the other three emission components in various ways. The findings suggest that emission-suppressing mechanisms associated with growing affluence are effective in mitigating direct end user emissions—typically the smallest component—but not the other three emission components. Therefore, high-income nations should prioritize mitigating emissions generated by supply chain activities outside the end use stage. The second empirical chapter is an examination of how renewable energy deployment is related to these emission components in high-income nations. I find that renewable energy deployment mitigates emissions by domestic-oriented supply chain activities, and with increasing effectiveness over time; yet it remains ineffective in curbing the other three emission components, indicating the existence of structural barriers that prevent the decarbonization effect of renewables from spilling over to these three emission components. These barriers must be overcome in order to achieve the full decarbonization potential of renewable energy deployment. In the third empirical chapter, I investigate the time-varying relationships between domestic income inequality and the four emission components, in order to unpack the multiple pathways linking income inequality to emissions. The results suggest that the relationships change over time, vary across emission components, and differ between measures of income inequality, which indicate variations in the causal pathways, both over time and across emission components. The findings from all three empirical chapters support the validity of the MEP framework. The relationships between greenhouse gas emissions and national affluence, renewable energy deployment, and domestic income inequality are multidimensional: these anthropogenic forces curb some emission components but spur others. Climate policies targeting these anthropogenic forces should optimize their decarbonization benefits while neutralizing the mechanisms through which they drive growth in emissions. / Thesis (PhD) — Boston College, 2022. / Submitted to: Boston College.

An analysis of the normative framework providing for human environmentally induced migration in SADC / Catherina Aletta Maas

Maas, Catherina Aletta January 2014 (has links)
Environmentally induced migration has been a contentious topic over the last two decades. Estimates show that over 30 million people worldwide are annually forced to migrate due to serious environmental degradation, natural disasters and depletion of natural resources. Thus the environment is irrefutably changing, and clear linkages can be drawn between environmental change and human mobility. Africa‘s developing status and its vulnerability in the context of environmental shocks compels research on prospective impacts and outcomes in order to develop proper mitigation and adaptation strategies, especially in Southern African Development Community (SADC) where the likelihood of protection measures being successfully implemented is relatively low. This dissertation is aimed at providing the reader with a detailed analysis of the regional normative framework regulating the issue of environmentally induced migration in SADC. Because environmental migrants are not considered to be ―refugees‖ in international law and on account of the fact that many policy makers and practitioners have their reservations as regards even acknowledging the existence of environmental migrants, protection and regulation in this regard is understandably lacking. A comprehensive framework is nonetheless required to regulate this phenomenon as it prompts serious security and sovereignty concerns. Until quite recently, most African countries had not even put in place national migration policies. Although many states have policies in place now, most have not yet been fully and effectively implemented. The normative framework governing specifically environmentally induced migration in SADC similarly renders rather disappointing results. Most of the applicable instruments do not directly raise the issue and the provisions indirectly touching upon the subject matter are subject to interpretation. A binding protocol must therefore be adopted by SADC Member States embracing elements contained in the instruments comprising the current framework. Such a protocol will however have to be liberal enough to acknowledge and provide for environmentally induced migration in its entirety whilst conservative enough so as not to undermine protection regimes for refugees in the true sense of the word. Conflicting interests and sovereignty considerations will, however, undoubtedly continue to hinder progress in this regard. The way forward is therefore away from ultimate sovereignty preservation and toward a regionalised approach where human rights no longer take a backseat. / LLM (Environmental Law and Governance), North-West University, Potchefstroom Campus, 2015

Rethinking conventional agriculture : the politics and practices of 'environmentally-friendly' production in the South African wine industry

Vink, Emma Maria 12 1900 (has links)
Thesis (MA)--Stellenbosch University, 2011. / ENGLISH ABSTRACT: When the South African wine industry re-entered the global wine markets in the early 1990’s, it faced a number of profound challenges. The most significant of these has been to gain a foothold in the international markets where both New and Old World wine producers fiercely compete for the consumer’s purse. In the effort to bolster its competitiveness and in response to a growing global trend towards ‘environmentally-friendly’ food production the industry launched the Integrated Production of Wine (IPW) scheme in 1998.This voluntary regulatory system provides guidelines for best agricultural practices and a producer must pass either the audit or the annual self-evaluation questionnaire in order to comply. A new Integrity & Sustainability seal has been introduced which advertises this compliance on each bottle of wine. This home-grown regulatory scheme is the first and only of its kind in the world and is now accepted by markets globally. The Biodiversity & Wine Initiative (BWI) is a collaboration between the wine industry and conservationists which aims to protect endangered species of the Cape Floral Kingdom, promote sustainable practices and rehabilitate indigenous flora and fauna on wine farms. Wines of South Africa (WOSA) is a marketing organisation which promotes the interests of South African wines in international markets. WOSA’s marketing slogan, ‘Variety is in Our Nature’ seeks to create a ‘common language’ which promotes the environmental aspects of South African wine production and a platform from which producers can establish their own marketing strategies. On the surface it would appear that the industry stands united behind this innovative initiative. But is this really the case? This thesis explores the views and attitudes of key industry informants as well as the responses of 14 different cellars from across the Western Cape. Each respondent was questioned on his/her notion of ‘environmentallyfriendly’, the cellar’s environmental practices, as well as their views IPW, BWI and WOSA’s efforts of promoting the South African wine industry’s new environmental identity. This study has found that the ‘greening’ of the South African wine industry enjoys broad support and compliance at both industry and cellar level. However, the results also show that there is serious criticism against the three-pronged ‘project’ which, if not addressed, could damage the integrity and credibility of industry’s new ‘image’ and undo its innovative edge. At the theoretical level, the study challenges aspects of both Global Value Chain Theory and Conventionalisation Theory. Regarding the former, the ‘home-grown’ way in which the industry has created its own ‘environmentally-friendly’ regulating scheme challenges the role lead firms take in international value chains. Regarding the latter, because IPW works within conventional agricultural practices and is far more cost effective than international ‘environmentally-friendly’ regulations, both large and small farmers can implement IPW regulations with the same effectiveness. / AFRIKAANSE OPSOMMING: Toe die Suid-Afrikaanse wynbedryf in die vroeë 1990s her-toegetree het tot die globale wynmark, het dit ‘n aantal ernstige uitdagings in die gesig gestaar. Die belangrikste hiervan was om’n vastrapplek te bekom in die internasionale markte, waar Nuwe, sowel as Ou Wêreld wynprodusente fel met mekaar kompeteer vir die verbruiker se beursie. In ‘n poging om die bedryf se mededingendheid te verbeter en in respons tot ‘n groeiende tendens na ‘omgewingsvriendelike’ voedselproduksie, het die bedryf in 1998 die sogenoemde Integrated Production of Wine (IPW) skema van stapel gestuur. Hierdie vrywillige regulasie-sisteem verskaf riglyne vir optimale landboukundige praktyke en die produsent moet òf die oudit slaag, òf aan die vereistes van ‘n jaarlikse self-evaluering voldoen. ’n Nuwe Integrity & Sustainability seël is in gebruik geneem wat die nakoming van die IPW reëls op elke bottel wyn adverteer. Hierdie tuis-ontwikkelde reguleringskema is die eerste en enigste van sy soort in die wêreld. Die Biodiversity & Wine Initiative (BWI) is ’n samewerkingsooreenkoms tussen die wynbedryf en omgewingsbewaarders wat ten doel het om die bedreigde spesies van die Kaapse Blommeryk te beskerm, volhoubare praktyke te bevorder en inheemse flora en fauna op wynplase te rehabiliteer. Wines of South Africa (WOSA) is ’n bemarkingsorganisasie wat die belange van Suid-Afrikaanse wyne op die internasionale markte bevorder. WOSA se bemarkingsleuse, ‘Variety is in our Nature’, het ten doel om ’n ‘gemeenskaplike taal’ te skep wat die omgewingsaspekte van die Suid-Afrikaanse wynproduksie bevorder en ‘n platvorm daarstel waarop produsente hulle eie bemarkingstrategieë kan lanseer. Op die oog af wil dit voorkom asof die bedryf verenig staan agter hierdie vernuwende inisiatief. Maar is dit werklik so? Hierdie tesis ondersoek die perspektiewe en houdings van sleutel mense in die bedryf, asook die response van 14 verskillende kelders van dwarsoor die Wes-Kaap. Elke respondent is gepols oor sy/haar opvatting oor wat ‘omgewingsvriendelik’ behels, die kelder se omgewingsvriendelike praktyke, hulle siening van IPW en BWI, sowel as WOSA se poging om die Suid-Afrikaanse wynbedryf se nuwe omgewingsidentiteit te bevorder. Die studie het bevind dat die ‘vergroening’ van die Suid-Afrikaanse wynbedryf breë steun geniet en die geïnstitusionaliseerde regulasies grootliks nagekom word. Die resultate wys egter ook dat daar ernstige kritiek is teen die bedryf se driedubbele ‘projek’ – soveel so dat as hierdie kritiek nie aangespreek word nie, dit die integriteit en geloofbarigheid van die bedryf se nuwe ‘beeld’ kan beskadig, en daarmee saam sy innoverende voorsprong ongedaan kan maak. Op ‘n teoretiese vlak bevraagteken die studie aspekte van beide Globale Waardeketting Teorie en Konvensionaliseringsteorie. Wat eg. betref bevraagteken die ‘tuisgemaakte’ manier waarop die bedryf sy eie ‘omgewingsvriendelike’ reguleringssisteem geskep het, die rol wat ‘leiersfirmas’ in internasionale waardekettings speel. M.b.t laasgenoemde: omdat IPW funksioneer binne die raamwerk van konvensionele landboupraktyke en baie meer koste-effektief is as internasionale ‘omgewingsvriendelike’ regulasies, kan klein sowel as groot produsente IPW regulasies met ewe veel effektiwiteit implementeer.

Sistema de reciclagem de veículos em final de vida : uma proposta ambientalmente mais sustentável para o cenário brasileiro

Coimbra, Núbia dos Santos January 2017 (has links)
A escassez de sistemas consolidados de reciclagem de veículos no Brasil e o grande volume de veículos em final de vida (VFVs) junto aos pátios do Departamento Estadual de Trânsito do Rio Grande do Sul - DETRAN/RS serviram de base para o desenvolvimento desta dissertação. Em face disso, o objetivo deste trabalho foi desenvolver um sistema de reciclagem de VFVs ambientalmente mais sustentável, a partir de exemplos globais de melhores práticas adotadas, atendendo à legislação vigente do país. Para tanto, a presente dissertação é composta por dois estudos fundamentados em revisões sistemáticas e em estudos de caso. Inicialmente, como resultado da primeira revisão sistemática, foi realizada a comparação de sistemas de gestão de reciclagem de veículos, identificados em 25 países. Essa comparação possibilitou ampliar o conhecimento de tecnologias e de procedimentos adotados em diferentes realidades, permitindo a proposição de oito políticas a serem adotadas em âmbito nacional, bem como três ações de melhoria ao atual sistema do DETRAN/RS. Em seguida, a segunda revisão sistemática permitiu a proposição de um sistema ambientalmente adequado para reciclagem de VFVs, que sirva de base para a futura padronização de processos de reciclagem, visando a potencial criação de centros especializados em reciclagem de veículos (CERVs). Diante do exposto, os resultados da pesquisa demonstraram que o tema da reciclagem de veículos está inserido num cenário mais amplo, necessitando da participação de todos os stakeholders envolvidos no processo, a exemplo: (i) das montadoras e fabricantes de peças, no desenvolvimento de tecnologias automotivas; (ii) dos entes federados, na criação de legislações mais rígidas e específicas, com foco na economia circular; e (iii) da sociedade na busca de produtos eco-amigáveis. Por fim, conclui-se que, associado às políticas e ações de melhoria sugeridas, a adoção do sistema ambientalmente adequado para reciclagem de VFVs proposto, poderá acelerar a criação de um ambiente favorável para o desenvolvimento e a consolidação da reciclagem no país. / The scarcity of consolidated vehicle recycling systems in Brazil and the huge amounts of endof- life vehicles (ELVs) at the Transit State Department of Rio Grande do Sul - DETRAN/RS courtyards served as the basis for the development of this Masters dissertation. Therefore, the objective of the work was to develop an environmentally more sustainable ELVs recycling system, based on global adopted best practices, without disregarding the country's current legislation. So, this dissertation is composed of two studies based on systematic reviews and on case studies. Initially, as a result of the first systematic review, a comparison of vehicle recycling management systems was carried out, identified in 25 countries. This comparison allowed the increasing of the knowledge about technologies and procedures adopted in different realities, making possible a proposal of educational policies to be adopted at national level, as well as three improvement actions for the current system of the DETRAN/RS. Subsequently, a second systematic review allowed a proposal for a suitable environmentally recycling system for the ELVs, which serves as the basis for a standardization of recycling processes, aiming the potential creation of specialized centers for such processes (CERVs). Considering this, the research results showed that the theme of product recycling is inserted in a broader scenario, requiring participation of all stakeholders involved in the process, such as: (i) the automakers and parts manufacturers, in the automotive technologies development; (ii) the federal entities, in the creation of more rigid and specific legislation, focusing on the circular economy; and (iii) the society in the search for eco-friendly products. Finally, it is concluded that, associated with the suggested policies and improvement actions, the adoption of the proposed environmentally appropriate system for the recycling of the ELVs, may accelerate the creation of a favorable way to the develop and consolidate the recycling in our country.

First, it was developed a significant conceptual and scientific debate, addressing the progression of the concepts, the classification criteria, the theoretical debate and estimates based on survey of multi-causal factors linked to environmental migration. Also, it was observed the contextualization of the thematic transformations inserted in the beginning of the century, with globalization and the strengthening of networks and the emergence of environmental problems globally. From there, it was up to the theoretical survey on about ways to manage the new international realities, adopting governance as the most effective means in order to provide and improve the protection of this new category of migrants. / O presente trabalho tem como objetivo analisar a gestão do processo migratório provocado pelas alterações ambientais, buscando compreender se determinadas ações são eficazes para a promoção, proteção e defesa da pessoa ambientalmente deslocada. Assim, primeiramente, se fez necessário um debate científico e conceitual significativo, abordando o desenvolvimento dos conceitos, os critérios de classificação, o debate teórico fundamentado em estimativas e o levantamento dos fatores multicausais vinculados à migração ambiental. Igualmente, observou-se a contextualização da temática inserida nas transformações no início do século XXI, com o fortalecimento da globalização e das redes e o surgimento dos problemas ambientais em âmbito global. A partir daí coube fazer os levantamento teóricos sobre as sobre as formas de administrar as novas realidades internacionais, adotando a governança como o meio mais eficaz, a fim de fornecer e melhorar a capacidade de proteção dessa nova categoria de migrante.
