"Marketing de créditos de carbono: um estudo exploratório" / Marketing of Carbon Credits: An Exploratory Research

Marco Antonio Conejero 17 March 2006 (has links)
O Protocolo de Quioto foi ratificado em Fevereiro de 2005 e com isso um mercado que vinha caminhando sem regras formais, contando com o pioneirismo de algumas empresas interessadas em aprender a lidar com esta nova commodity e preocupadas com a sua imagem corporativa, passou de fato às vias da formalidade. Assim, uma vez que o mercado de Reduções Certificadas de Emissões (RCEs) possui um arcabouço institucional estabelecido, é interessante estudar com base na Economia dos Custos de Transação (ECT), como os custos de transação induziram modos alternativos de governança, em particular os contratos entre empresas proponentes de projetos de MDL (Mecanismo de Desenvolvimento Limpo) e os canais de comercialização constituídos por organizações multilaterais. E esse estudo, conforme as recomendações de Williamson (1993; 1991; 1985), foi feito analisando as características das transações em termos de especificidade de ativos, freqüência e incerteza, dados os pressupostos comportamentais dos agentes (racionalidade limitada e oportunismo). Para tanto, a pesquisa lançou mão do método do estudo de caso para obter informações privadas sobre as transações de RCEs, e seus respectivos contratos, entre as empresas brasileiras e uma organização multilateral, o Banco Mundial. Um resultado é que, diferente das relações via mercado, as empresas brasileiras se beneficiaram - em termos de redução dos custos de transação - da transação de RCEs (via contrato) com o Banco Mundial, já que este exerce todas as funções de um típico canal de distribuição, exceto a de aquisição dos direitos de propriedade sobre os créditos. / The Kyoto Protocol was approved in February 2005 and the carbon market that was without rules, played by some pioneer companies interested in learning by doing with this new commodity and worried about their corporate image, started working in the ways of the formality. As the market of Certified Emissions Reduction (CER) has already an established Institutional Environment, it’s interesting to study, based on the Transaction Costs Economics (TCE) theory, how the transaction costs induced alternative ways of governance, in particular the contracts between Brazilian companies – with CDM (Clean Development Mechanism) projects - and the commercialization channels in multi-lateral organizations. This study, as the recommendations of Williamson (1993; 1991; 1985), was made analyzing the characteristics of the transactions in terms of asset specificity, frequency and uncertainty, considering the human behavior assumptions (limited rationality and opportunism). For this, the research used the case studies method to obtain private information about the transactions of CER, and their contracts, between Brazilian companies and a multi-lateral organization, the World Bank. A result is that, differently of the spot market relationship, the Brazilian CDM projects benefited - in terms of reduction of transaction costs – with the CERs transactions (contracts) involving the World Bank, since this bank realizes every distribution channel functions, except the acquisition of CERs property rights.

Nástroje ekonomické regulace k ochraně životního prostředí v oblasti energetiky v ČR / Tools of Economic Regulation to Protect the Environment in the Field of Energy in the Czech Republic

Melichová, Jana January 2014 (has links)
This thesis deals with instruments of economic regulation related to environment protection in the field of energetics. It surveys selected instruments in the form of ecological taxes and Emission Trading System. It clarifies the origin and development of these instruments and their integration into the legislation of the Czech Republic. The major aim of the thesis is to analyze the impact of ecological taxes and trading with emission permits on management decisions of a company.The analysis and calculations have been carried out in a real enterprise. I have tried to prove how the System of Emission Trading impacts on the management decision and strategic goals of a company due to further development of the EU System of Emission Trading, its changes as well as changes in production of a company.

Kdo hýbe klimatem? Aktéři a vlivy v mezinárodní klimatické politice / Who Drives the Climate? Actors and Influences in International Climate Policy

Husová, Kateřina January 2008 (has links)
Climate change has recently arised in the international agenda as one of the top issues. The paper first provides with a theoretical comprehension of actorness in international relations. Second, the paper examines milestones of the historic development of the current climate regime. Third, the focus turns to the major actors which influence the climate change negotiations and examines their preferences, their evolution and pursuit on the international scene. It assumes politics is a two-level game and that political factors are not exclusive driving forces on the international scene. Finally, remarks on the future of climate regime are presented. The paper concludes by stating that actors differ in social identification with natural reality and that the shift in current environmental paradigm is rather unlikely.

Road transportation impact on Ghana's future energy and environment

Faah, George 24 July 2009 (has links)
This research work explored the environmental and socio-economic benefits derived, if some proportion of daily passenger trips made using private cars in Ghana could be shifted to the use of public transport. The research applied the computer software COPERT III in estimating road transport Greenhouse gas (GHG) emissions and fuel consumption in Ghana for the base year 2005 and forecast years 2010 and 2020. The research reveals that if no major change occur in policies or economic determinants in meeting road transport and energy in Ghana, then the 2005 total emissions value is expected to rise by 36% in 2010 and over double in 2020 i.e. from 4.6 to 6.25 in 2010 and to 9.77 Mt CO2e in 2020. However, if just 10% of daily passenger trips using private cars can be shifted towards the use of public transport, then the end results in reduction in emissions could earn Ghana about $USD 6.6million/year under the Kyoto Protocol CDM initiative. The research also demonstrated that with a further 10% daily passenger trip shift, the outcome could be more promising, increasing to $USD 13million/year.

Optimization and control of a large-scale solar chimney power plant

Pretorius, Johannes Petrus 03 1900 (has links)
Thesis (PhD (Mechanical and Mechatronic Engineering))-- University of Stellenbosch, 2007. / ENGLISH ABSTRACT: The dissertation builds on previous research (Pretorius, 2004) and investigates the optimization and control of a large-scale solar chimney power plant. Performance results are based on a reference location near Sishen in South Africa and a so-called reference solar chimney power plant, with a 5000 m collector diameter and a 1000 m high, 210 m diameter chimney. The numerical simulation model is refined and used to perform a sensitivity analysis on the most prominent operating and technical plant specifications. Thermo-economically optimal plant configurations are established from simulation results and calculations according to an approximate plant cost model. The effects of ambient wind, temperature lapse rates and nocturnal temperature inversions on plant performance are examined. Various new technologies are investigated for the purpose of controlling plant output according to specific demand patterns. The incorporation of vegetation under the collector roof of the plant and the influence thereof on plant performance is also explored. Results indicate that, through the modification of the collector roof reflectance, collector roof emissivity, ground surface absorptivity or ground surface emissivity, major improvements on plant performance are possible. Introducing thermal insulation or double glazing of the collector roof also facilitates substantial enhancements on plant yield. Simulations predict a notable sensitivity to the ground surface absorptivity value, while variable atmospheric temperature lapse rates and windy ambient conditions may impair plant performance significantly. Furthermore, sand is found to be unsuitable as plant ground type and thermoeconomically optimal solar chimney plant dimensions are determined to be generally larger than plant dimensions employed in previous studies. Good dynamic control of solar chimney power output is established, suggesting that a solar chimney power plant can be implemented as a base or peak load electricity generating facility. Lastly, results predict that vegetation, when provided with sufficient water, will be able to survive under the collector roof but the inclusion of vegetation will however cause major reductions in plant performance. / AFRIKAANSE OPSOMMING: Die proefskrif bou op vorige navorsing (Pretorius, 2004) en ondersoek die optimering en beheer van 'n grootskaalse sonskoorsteen-kragstasie. Uitsetresultate word baseer op 'n verwysingsligging naby Sishen in Suid-Afrika en 'n sogenaamde verwysingskragstasie, met 'n kollektor deursnee van 5000 m en 'n 1000 m hoë, 210 m deursnee skoorsteen. Die numeriese rekenaarmodel is verbeter en gebruik vir die uitvoering van 'n sensitiwiteits-analise op die belangrikste bedryfs- en tegniese kragstasie spesifikasies. Termo-ekonomiese optimale aanlegkonfigurasies is bepaal volgens die uitsetresultate van die rekenaarmodel en benaderde aanleg-kosteberekeninge volgens 'n eenvoudige kostemodel. Die invloed van wind, atmosferiese temperatuur gradiënte en nagtelike temperatuur inversies op kragstasie uitset word beskou. Verskeie nuwe tegnologië word ondersoek met die doel om aanleg uitset te kan beheer volgens spesifieke elektrisiteit aanvraagspatrone. Die inkorporasie van plantegroei onder die kollektordak, en die invloed daarvan op kragstasie uitset, word ook beskou. Bevindings dui aan dat, deur die wysiging van die kollektordak refleksie, kollektordak emissiwiteit, grondoppervlak absorptiwiteit of grondoppervlak emissiwiteit, groot verbeterings op aanleg uitset moontlik is. Die implementering van termiese isolasie of 'n dubbelglaslaag vir die kollektordak veroorsaak ook 'n beduidende verheffing in kragstasie uitset. Simulasies voorspel 'n merkbare sensitiwiteit teenoor die grondoppervlak absorptiwiteitswaarde, terwyl veranderlike atmosferiese temperatuur daaltempos en winderige omgewingstoestande aanleg uitset beduidend mag belemmer. Verder is bevind dat sand ongeskik is as aanleg grond tipe en dat termo-ekonomiese optimale sonskoorsteen-kragstasie dimensies in die algemeen groter is as die aanvaarde aanlegdimensies van vorige studies. Goeie dinamiese beheer van sonskoorsteen-kragstasie uitset is bevestig, wat suggereer dat die sonskoorsteenkragstasie as 'n basis of pieklas elektrisiteitopwekkings-aanleg ingespan kan word. Ten laaste voorspel resultate dat plantegroei, mits dit voorsien word van genoegsame water, sal kan oorleef onder die kollektordak maar dat die inkorporasie van plantegroei die aanleg uitset beduidend sal benadeel. / Sponsored by the Centre for Renewable and Sustainable Energy Studies

從國內消費面估算臺灣二氧化碳排放量 / Estimating CO2 Emissions from the Perspective of Domestic Consumption in Taiwan with a Multi-objective Programming Model

張智堯, Chang,Chih Yao Unknown Date (has links)
本文主旨在於透過國內消費重新估算臺灣二氧化碳排放量。蓋全球各區域二氧化碳排放量的變動,透過貿易分工而移轉,若只用一國國內生產面估算二氧化碳的排放量,將忽略了各國實際消費的二氧化碳排放量,並使《京都議定書》防止全球暖化的原意大打折扣。因為已開發國家為了達到氣體減量政策的目標,可將二氧化碳排放密集的產業遷移至低度開發國家,溫室氣體的排放只是由締約國轉移到非締約國而已。反之,若以消費面二氧化碳排放量作為二氧化碳減量之依據,則能更有效地提供減量誘因,促進減量技術之發展或誘導節約用能與需求消費。爰此,本文先以透過產業關聯模型調整消費面的臺灣二氧化碳排放量估算值,並以排放減量的觀點分析產業部門之進出口來源國,最後透過多目標規劃模型,進行二氧化碳減量之政策分析,並提出產業發展建議。 / This paper aims at estimating the CO2 emissions of Taiwan from the perspective of domestic consumption side. Since the developed countries would achieve the emission reduction goal by transferring their emission-intensive industries form their lands to the developing countries, we would neglect the true CO2 emissions of nations if we only estimate their CO2 emissions from the perspective of domestic production side, therefore reduce the significance of the Kyoto Protocol, which aims at reducing emissions. On the contrary, If we estimate the CO2 emissions of nations through the consumption side, we can provide the incentives for emission reduction more effectively, prompting the development of the technology of emission reduction or inducing consumers to conserve the use of energy. Consequently, this paper first estimates the CO2 emissions of Taiwan from the perspective of domestic consumption side through an input-output model, then estimates the import and export emissions of industry sectors, finally it analyzes the policies for CO2 emission reduction by a multi-objective programming model and provides suggestions for the development of industries.

全球治理對國家公共政策影響之指標建構:京都議定書對台灣公共政策影響之個案分析

許耿銘 Unknown Date (has links)
在目前相關文獻中,在全球治理架構下所制定的政策,必將對於各國內部相關政策造成影響。然而,這樣的聯想常被視為是理所當然,卻鮮有實證資料,證明一個國家的公共政策在全球治理的架構下,是否真正受到影響?在哪些面向會受到影響?這些面向實際受到影響的程度為何?需要藉由何種工具,來衡量國家政策受到全球治理影響的程度? 為了解答上述之問題,本文之研究目的可歸納為以下三點: 1.經由全球治理、全球治理與國家公共政策間關係等文獻探討建立全球治理影響國家公共政策之理論架構 2.藉由理論架構與政策德菲法建立全球治理影響國家公共政策之指標系統 3.透過指標系統實證檢驗京都議定書對於台灣公共政策之影響 本研究最後獲致三大重要成果。首先,建構出全球治理影響國家公共政策之「GG-NPP理論架構」;其次,經由政策德菲法的徵詢結果,彙整出適合用以衡量全球治理對於國家公共政策影響之指標系統,共可分為三大面向、六大變數以及十六項指標。再者,透過前述的指標系統,以京都議定書為個案檢證台灣現行因應之政策。透過數據的整理,發現我國在十六項指標項目中,有十項是呈現因應京都議定書的正向趨勢;但是其餘六項指標,由於受到如主權、國際現實環境等外在因素的侷限,或者是受制於政府自己內部的組織、人事、預算、府際關係等因素,故而全球治理並未對於國家公共政策的結果必然造成影響。 / In some relative literature, we can see the policy outcomes in the national governance level “could” be affected by those in the global level. But there is little practical evidence to affirm such cause and effect. How can we evaluate exactly such relation, dimension and degree? This paper will be grouped into third parts. First, I will review the literature of global governance, the relations between global governance and public policy. By doing so, the theory framework could be formulated. Second, I will select and construct the dimensions, variables and indicators that are related to the relations between global governance and public policy. And I will check and confirm the dimensions and indicators through the “Policy Delphi” method to build the indicator system completely. Third, I will evaluate the impacts of Kyoto Protocol on public policy in Taiwan. Finally, I got three important outcomes. First, I formed a “GG-NPP theory framework”. Second, I constructed an indicator system that can be formed to measure the relation between global governance and public policy by two round “Policy Delphi” process. There are three dimensions, six variables and sixteen indicators in this indicator system. Third, I examine the indicator system by the case of “Kyoto Protocol”. I checked the impacts of Kyoto Protocol on public policy in Taiwan and found some interesting outcomes. And I knew the impacts of Kyoto Protocol on public policy will be affected by some external and internal elements.

O Protocolo de Kyoto e os países em desenvolvimento: uma avaliação da utilização do Mecanismo de Desenvolvimento Limpo / Kyoto Protocol and developing countries: analyses of Clean Development Mechanism adoption

Godoy, Sara Gurfinkel Marques de 14 February 2011 (has links)
Com base na Nova Economia Institucional, o foco desta pesquisa foi o de identificar os custos de transação existentes nos projetos de MDL (Mecanismo de Desenvolvimento Limpo) e investigar se eles são barreiras para o desenvolvimento do projeto, e se podem afetar a eficiência de projetos já implantados. Mais especificamente, foram analisadas as variáveis que afetam as diferenças entre as reduções de emissões estimadas nos projetos de MDL e as reduções realmente verificadas (Sucesso de Redução - SR), depois do projeto implantado e monitorado. A fim de cumprir esse objetivo, esta pesquisa contou com levantamento de dados secundários relativos aos projetos de MDL realizados em todo o mundo, e dados primários relativos aos projetos brasileiros de MDL. A análise das informações mostrou que os países mais relevantes em número de projetos são Índia, China, Brasil, mas este ranking se altera dependendo da variável analisada (por exemplo, volume de emissão reduzida ou estimada). Os setores mais relevantes em volume de redução são de HFC, N2O, mas este perfil se altera quando analisado o número de projetos, ficando em primeiro lugar biomassa, hidroelétrica e energia eólica. Em relação ao SR, a maior parte dos projetos não apresenta eficiência satisfatória. No entanto, em volume de reduções a maior parte dos projetos cumpre mais que 91% de SR. Os setores mundiais mais eficientes são N2O e HFC (Brasil N2O e troca de energia fóssil), e os setores de resíduos sólidos e agricultura (Brasil, agricultura e resíduos sólidos) são os menos eficientes. Finalmente, esta pesquisa conclui que custos de transação afetam o sucesso da redução de MDL, e os mais importantes são os custos ex-ante, resultantes de problemas de falhas de informação (como, por exemplo, problemas com as organizações que intermedeiam o processo dos MDLs) e problemas de mensuração (problemas relacionados com metodologias dos MDLs). / Based on the New Institutional Economics, the focus of this research was to identify transaction costs in CDM projects (Clean Development Mechanism) and investigate if they can affect project efficiency, and also if they create project development barriers. More specifically, this research analyzed the variables that could affect the differences between CDM estimated emission reduction projects and actual reductions obtained (Reduction Success - RS) after the project has been implemented and monitored. To fulfill this goal, this research included a secondary global CDM projects data survey, and primary data survey related to Brazilian CDM projects. Data analysis showed that the most important countries in terms of number of projects are India, China, Brazil, but depending on the variable analyzed (for instance, emission reduction volume) this ranking could change. The most relevant sectors in emission reduction volume were HFCs, N2O, but this would change when we analyze number of projects, where biomass would come first, followed by hydroelectric and wind energy. When considering RS, most projects do not show satisfactory performance. However, in terms of emission reductions amount, most of the projects achieve more than 91% RS. The most efficient sectors in the world are HFC and N2O (in Brazil, N2O and fossil fuel), and the least efficient sectors are solid waste and agriculture (in Brazil, agriculture and solid waste). Finally, this research concludes that transaction costs affect the success of CDM reductions, and the most relevant are ex-ante costs, resulting from information problem gaps (these problems relate to parties involved in the CDM process) and measurement problems (CDM methodologies).

O protocolo de Kyoto e o mecanismo de desenvolvimento limpo: Uma avaliação de suas possibilidades e limites. / Kyoto Protocol and clean development mechanism: potencialities and limits evaluation

Godoy, Sara Gurfinkel Marques de 18 October 2005 (has links)
Made available in DSpace on 2016-04-26T20:48:35Z (GMT). No. of bitstreams: 1 SaraGodoy.pdf: 5804152 bytes, checksum: baeceffd1a1f8912ffc807d85cb63398 (MD5) Previous issue date: 2005-10-18 / The purpose of this work is to present the limits and benefits of Clean Development Mechanism (CDM) Projects implementation. The supplemental objectives are the limits and potentialities evaluation of the Kyoto Protocol and the Tools for the Demonstration and Assessment of Additionality analysis, that is an tool proposed by CDM Executive Committee enabling the companies who propose the CDM projects to prove the additionality of its projects. The Protocol firmed in 1997 during COP 3 (3rd Conference of Parts) of United Nations Framework Convention on Climate Change (UNFCCC), in Kyoto, determined emissions ceiling for some developed countries, considering an institucional apparatus to provide support to the process implementation. In order to make flexible the goals fullfilment, the Protocol creates mechanisms (the Mechanism of Clean Development, the Joint Implementation and the Emissions Trade) that also allow the fullfilment of the reduction objectives. The countries can reach its reduction goals, purchasing emission reduction from other countries. Therefore, these tools enable and improve the carbon market. As relevant part of this work, the CDM appears as a great tool that if well used, can bring benefits for development countries, bringing up economic and enviromental advantages once these projects are implemented in its territories, promoting the sustainable development. There are still plenty of challenges ahead for the CDM and the Protocol development, as reduce the uncertainties of regulatory framework, minors transaction costs and institutional improvements that can be reached. Related to the Tools for the Demonstration and Assessment of Additionality, it fullfils with its function to demonstrate adittionnality, not limiting or promoting new CDM projects / O trabalho objetiva apresentar os limites e benefícios da implantação do Mecanismo de Desenvolvimento Limpo (MDL). Os objetivos subsidiários ao principal são a avaliação mais ampla dos limites e potencialidades do Protocolo de Kyoto e a análise mais específica do Teste de Adicionalidade, que é um instrumento proposto pelo Comitê Executivo do MDL com o intuito de que os proponentes de projetos de MDL possam comprovar se seus projetos são adicionais. O Protocolo firmado em 1997 durante a COP 3 (3º Conferência das Partes) da Convenção-Quadro das Nações Unidas sobre Mudanças do Clima (CQNUMC), em Kyoto, determinou um teto de emissões para vários países desenvolvidos e propôs um aparato institucional para dar sustentação à implantação desse processo. Buscando uma maior flexibilidade no cumprimento das metas, o Protocolo cria mecanismos de flexibilização (o MDL, a Implementação Conjunta e o Comércio de Emissões) que procuram assegurar o cumprimento dos objetivos de redução. Os países podem alcançar suas metas de redução por intermédio de compras de reduções de emissão de outros países. A criação dessas ferramentas possibilita, portanto, o surgimento de um mercado de certificados de carbono. Como parte relevante desse trabalho, o MDL aparece como uma grande ferramenta, que se bem utilizada, pode ser muito benéfica aos países em desenvolvimento, pois pode trazer vantagens econômicas e ambientais com a implantação dos projetos em seus territórios, promovendo assim o desenvolvimento sustentável. Há vários obstáculos a serem transpostos para o maior desenvolvimento do MDL e do Protocolo, como maior regulação, menores custos de transação e melhorias institucionais que podem ser obtidas. Quanto ao Teste de Adicionalidade ele cumpre com sua função de demonstrativo de adicionalidade, não sendo nem limitador nem promotor de novos projetos.
