Indirect emissions estimation model for investments in the automobile sector, fossil fuel sector and utilities sector / Estimering av indirekta emissioner i fordonssektorn, fossila-bränslen-sektorn och energisektorn

Thungström, Kerstin January 2018 (has links)
To combat climate change multiple initiatives have been launched to steer the financial market towards a more sustainable and resilient path. For example the Montreal Pledge that have committed over 120 investors to measure and disclose their carbon footprints of their portfolios. ISS-Ethix Climate Solution provides climate change related services to investors. In order to evaluate companies’ sustainability ISS-Ethix Climate Solution estimates companies’ direct and indirect greenhouse gas emissions. To simplify these estimations, the emissions from corporations are divided into three scopes, where scope 1 and 2 cover the emissions from the combustion of fuels used in the company and electricity generation. Scope 3 corresponds to all other emissions generated upstream and downstream the companies’ supply chain. The aim of this study was to help ISS-Ethix Climate Solution to develop a model that estimates the indirect scope-3-emission intensity for companies in the automobile sector, fossil fuel sector and utility sector. The first objective was to examine if the variations within the sectors could be explained and categorized. To carry this out each sector was defined and their emission sources identified. The emissions could be explained and categorized for the automobile sector and fossil fuel sector. However, the emissions for the utility sector could only partly be explained and categorized. The second objective was to examine which parameters and subcategories were relevant for estimating the emissions. Two methods were investigated to carry out the second objective; correlation analysis and the average-data method. No correlations could be found between any of the sectors and the selected parameters. The estimated emissions using the average-data method were verified to the companies reported emissions. For the automobile and the fossil fuel companies the estimated emissions followed the same trend as the reported data. However, no trend could be found for the utility companies. Estimating emissions using the average-data method requires a certain corporation structure. The method can be used for corporations with a specific output, but does not suit corporations with a more complex structure. The largest limitation with the models was the information shortages from the corporations. Therefore increased transparency from the companies is a necessity in order to develop the models. / För att minska klimatförändringen har ett flertal initiativ lanserats för att göra finanssektorn mer hållbar. Tillexempel Montreal förbindelsen som har fått över 120 investerare att mäta och publicera klimatutsläppen i sina aktieportföljer. Företaget ISS- Ethix Climate Solution erbjuder klimatrelaterade tjänster för investerare. För att värdera hur hållbart ett företag är estimerar ISS-Ethix deras direkta och indirekta utsläpp av växthusgaser. För att förenkla dessa estimeringar är utsläppen indelade i tre så kallade scopes (områden), där scope 1 och 2 motsvarar emissionerna som genereras av att företaget förbränner fossila bränslen och deras elanvändning. Scope 3 motsvarar alla utsläpp som sker uppströms och nedströms företagens leverantörskedja. Syftet med denna studie var att hjälpa ISS-Ethix Climate Solution att utveckla en modell som estimerade scope 3 utsläppen från företag inom fordonssektorn, fossila- bränslen-sektorn och energisektorn. Det första målet var att undersöka om variationerna inom sektorerna kunde förklaras och kategoriseras. Detta utfördes genom att varje sektor först definierades och utsläppskällorna identifierades. Emissionerna kunde förklaras och kategoriseras för fordonssektorn och fossila-bränslen-sektorn. Däremot kunde utsläppen från energisektorn bara delvis förklaras och kategoriseras. Det andra målet var att undersöka vilka parametrar och sub-kategorier som var viktiga för att estimera sektorernas emissioner. För att göra detta undersöktes två olika metoder; korrelationsanalys och medelvärdesmetoden. Inga korrelationer kunde hittas mellan någon av sektorerna och de undersökta parametrarna. De estimerade emissionerna när medelvärdesmetoden användes, verifierades mot företagens självrapporterade utsläpp. För fordonssektorn och fossila-bränslen-sektorn följde de estimerade och rapporterade utsläppen samma trend. Däremot påträffades ingen trend för energibolagen. Att estimera växthusgasutsläpp med hjälp av en medelvärdesmetod kräver en viss typ av företagsstruktur. Metoden kan användas för företag med en specifik produkt, men är inte lämplig för företag med en mer komplex struktur. Modellernas största begränsning var informationsbristen från företagen. Därför behövs mer transparens från företagen för att kunna utveckla modellerna.

Thus, the economic intervention of the State prioritizes the formation of a joust economic order and in this context, it fulfills to us to define, to the long one of this work, the contours of the intervention of the State in the economic domain in the presence of the Federal Constitution of the Republic of 05 of October of 1988, and, more specifically, in the petroliferous economic sector by means of the interventive contribution instituted after the Constitutional amendment 33/2001, with Law 10.336/2001. With the creation of this institute, in Brazil, emerged innumerable quarrels concerning its constitutional legitimacy, directing uncurling of the research to the study of the state intervention through this contribution and its constitutional limits, in the purpose to demonstrate the parameters for its institution and application. In this way, the interventive contribution in the fuel sector (CIDE-Combust?veis) shows itself as an intervention instrument on the economic domain, acting in way to finance the indirect performance of the State, specially in what concerns to the promotion of the principle of sustainable development principle. Therefore, CIDE-Combust?veis is an able instrument to concretizes the mentioned constitutional principle. Thus, the division of its incomes promotes the consolidation of the principle of the cooperative federalism. In this direction, from premises of the environmental tax law, this intends to demonstrate the utility and constitutionality of this exaction tax, primordially with regard to the realization of the basic right to the balanced environment / A atua??o do Estado na ?rea econ?mica somente se legitima quando se realizar em virtude da prote??o dos princ?pios estabelecidos constitucionalmente. Assim, a interven??o econ?mica do Estado prioriza a forma??o de uma ordem econ?mica justa e, nesse contexto, cumpre-nos definir, ao longo deste trabalho, os contornos da interven??o do Estado no dom?nio econ?mico perante a Constitui??o Federal da Rep?blica de 05 de outubro de 1988, e, mais especificamente, no setor de combust?veis por meio da contribui??o interventiva institu?da ap?s a EC 33/2001, com a Lei 10.336/2001. Com a cria??o deste instituto, no Brasil, vieram ? baila inumer?veis discuss?es acerca de sua legitimidade constitucional, dirigindo-se o desenrolar da pesquisa ao estudo da interven??o estatal por meio desta contribui??o e seus limites constitucionais, no fito de demonstrar os par?metros para sua institui??o e aplica??o. Desta maneira, a CIDE-Combust?veis se mostra como um instrumento de interven??o, atuando de maneira a financiar a atividade do Estado, especialmente no que pertine ? promo??o do princ?pio do desenvolvimento sustent?vel. Nesse mister, a CIDE-Combust?veis se mostra instrumento h?bil a concretiza??o do princ?pio constitucional mencionado. De seu turno, a reparti??o de suas receitas promove a consolida??o do princ?pio do federalismo cooperativo. Nesse sentido, a partir de premissas do direito tribut?rio ambiental, este trabalho procura demonstrar a utilidade e constitucionalidade dessa exa??o tribut?ria, primordialmente no que pertine ? efetiva??o do direito fundamental ao meio ambiente equilibrado
