No. of bitstreams: 1 ROSELEI HAAG_.pdf: 1169810 bytes, checksum: 1591d24df570168350007209b0cb307d (MD5) Previous issue date: 2015-03-30 / Nenhuma / O objetivo deste trabalho foi identificar a relação entre o desempenho ambiental com a terceirização, a colaboração ambiental com os fornecedores e a multinacionalidade. A pesquisa propôs três hipóteses derivadas da literatura, e as testou a partir de dados de survey em plantas de manufatura. Para tal, os construtos utilizados foram extraídos do projeto de pesquisa internacional denominado High Performance Manufacturing (HPM). A amostra consiste em empresas do banco de dados da quarta rodada do projeto, coletado em três setores (eletroeletrônico, veículos automotores e máquinas e equipamentos). Após o tratamento dos dados, obteve-se o total de 257 pesquisas válidas. Os dados foram analisados estatisticamente através de Modelagem de Equações Estruturais. Como resultado, a pesquisa identifica que a colaboração ambiental com fornecedores influencia positivamente o desempenho ambiental nas plantas da amostra. No entanto, não foi encontrada relação significativa entre a multinacionalidade e a terceirização com o desempenho ambiental. Este trabalho contribui às discussões teóricas e práticas para os estudos de estratégia em manufatura, ao demonstrar empiricamente que as práticas de colaboração ambiental com os fornecedores podem resultar em uma melhoria do desempenho ambiental. / The purpose of this study was to identify the relationship between the environmental performance with outsourcing, environmental cooperation with suppliers and multi-nationality. The research proposed three hypotheses derived from the literature, and tested from by a database survey on manufacturing plants. To this end, the constructs used have been taken from the international research project called High Performance Manufacturing (HPM). The sample consists of companies out of a database in the fourth round of the project, collected in three sectors (electronics, motor vehicles and machinery and equipment). After processing the data, we obtained a total of 257 valid surveys. The data have been statistically analyzed by Structural Equation Modeling. As for the results, this identifies that the environmental cooperation with suppliers has a positively influence to the environmental performance in the plants. However, there was no significant relationship between multinationality and outsourcing with environmental performance. This present work contributes to the theoretical and practical discussions for manufacturing strategy in studies to empirically demonstrate that the environmental practices of collaboration with suppliers may result in an improvement of environmental performance.

Esta pesquisa tem como principal objetivo analisar os indicadores de desempenho ambiental mais divulgados pelas principais empresas do setor, signatárias do Global Reporting Iniative (GRI). Para tal, foram avaliados seus relatórios de sustentabilidade ambiental para o período de 2010 a 2014, bem como estabelecidos critérios para a seleção dos indicadores a serem estudados. Com relação aos indicadores de desempenho ambiental mais divulgados, EN3 (Consumo Energético), EN8 (Total de retirada de água por fonte), EN16 (Total de emissões diretas e indiretas de GEE), EN20 (NOx, SOx e outras emissões atmosféricas significativas), EN22 (Peso total de resíduos, por tipo e método de disposição) e EN23 (Número e volume total de derramamentos significativos); as empresas, em sua maioria, apresentaram melhora em seu desempenho ao longo dos anos. O indicador EN22, bem como o indicador EN3, foram os que apresentaram os melhores desempenhos pelas empresas. Apesar da melhoria das práticas observadas pelas empresas, observa-se que o indicador EN20 apresentou os resultados mais desfavoráveis. Com efeito, a análise crítica, quanto à aplicação dos indicadores e das práticas de melhoria adotadas pelas empresas, auxilia na avaliação do seu desempenho e gestão ambiental, sendo possível a proposição de melhorias no que está sendo realizado pelas mesmas no referente a sustentabilidade, em seu aspecto ambiental. / The Companies of the exploration and production sector of oil and gas are increasingly incorporating the environmental variable in their processes, through the adoption of environmental sustainability indicators. This research has as main objective to analyze the environmental sustainability indicators most publicized by the major oil companies’ signatories of the Global Reporting Initiative (GRI). To this end, the environmental sustainability reports were evaluated for the period 2010 to 2014, and criterias were established for the selection of environmental sustainability indicators to be studied. Considering the most publicized environmental performance indicators, EN3 (Energy Consumption), EN8 (Total water withdrawal by source), EN16 (Total direct and indirect GHG emissions), EN20 (NOx, SOx and other significant air emissions), EN22 (Total weight of waste by type and disposal method) and EN23 (Total number and volume of significant spills); the majority of companies showed improvement in their performance over the years. The EN22 indicator, as well as the EN3 showed the best performance by companies. Despite improvements in practices observed by the companies, it’s observed that the EN20 indicator showed the most unfavorable results. Indeed, the review of the application of indicators and improvement practices adopted by companies may assist in the evaluation of its performance and environmental management, making possible to propose improvements being carried out by them in respect of environmental sustainability.

Gestão de empreendimentos e soluções técnicas para a realização de edifícios sustentáveis certificados pelo processo AQUA. / Project management and technical solutions to carry out sustainable buildings

Adriana Gouveia Rodrigo 12 September 2011 (has links)
A presente pesquisa contribui para a realização de edifícios com um maior desempenho socioambiental e em equilíbrio com as questões culturais e econômicas atuantes no contexto dos empreendimentos. Foram estudados três casos que utilizaram o referencial do Processo AQUA (método de avaliação de empreendimentos sustentáveis, de origem francesa). O escopo da pesquisa está limitado às etapas do empreendimento que vão da concepção do projeto ao término da construção. Os objetivos propostos são identificar e analisar como o processo de gestão de empreendimentos se altera para a realização de edifícios com um melhor desempenho socioambiental, e os impactos dos requisitos propostos pelo referencial do Processo AQUA na elaboração das soluções técnicas e de outras estratégias, presentes nos projetos dos edifícios estudados. Adota como método de pesquisa o estudo de caso, baseado em entrevistas e análise documental. Os resultados e conclusões apontam que deve haver a participação de todas as partes interessadas, dando especial atenção à necessidade da formação da equipe de projetos logo nas primeiras fases da realização do empreendimento; também indicam que novas competências passam a fazer parte do processo e devem ser integradas à equipe, em momentos adequados, e que as soluções técnicas se desenvolvem de forma contínua e mais acelerada nos empreendimentos de edifícios de alto desempenho socioambiental, pois estes apresentam novas proposições de projeto que demandam desenvolvimento tecnológico dos projetistas, dos fabricantes de materiais e das empresas construtoras. / This research contributes to carrying out buildings with a higher environmental performance and in harmony with economic and cultural issues that take place in the projects context. It studied three cases, which employed the reference guide of the AQUA Process (a sustainable buildings assessment method of French origin). The scope of the research is limited from the concept design phase to the end of the construction phase. The objectives are to identify and analyze how the process of project management changes in order to improve the environmental performance of the buildings, and the impacts of the AQUA Process requirements on the development of technical solutions and other strategies, in the buildings studied here. As a research methodology it makes use of the case study, based on interviews and documentary analysis. The findings and conclusions indicate the need for the participation of all stakeholders, giving special attention to the necessity of shaping the project\'s team in the very first stages of the activity; they also reveal that new skills become part of the process and should be integrated into the team, at appropriate times, and that technical solutions are developed continuously and faster in high-performance building projects due to the new proposals they present, which demand technology development of designers, material manufacturers and construction companies.

Relação entre as práticas de Produção mais Limpa e as de Produção Enxuta: estudos de casos múltiplos e survey sobre os impactos no desempenho ambiental, econômico e operacional da empresa / Relationship between Cleaner Production to the Lean Production practices: multiple case studies and survey on the impact on environmental, economic and operational performance of organization

José Augusto de Oliveira 03 June 2016 (has links)
Os princípios e as práticas de Produção Enxuta e de Produção mais Limpa contribuem para a geração de valores com perspectivas diferentes. São valores focados respectivamente em sustentabilidade econômica e em sustentabilidade ambiental que, alcançados complementarmente podem contribuir para a satisfação dos stakeholders de forma mais sustentável. Estudos apresentam compatibilidades entre a Produção Enxuta e as diferentes abordagens de Sustentabilidade Ambiental, contudo, poucas pesquisas exploram empiricamente as relações entre estes constructos, mostrando uma lacuna a ser preenchida no meio acadêmico e empresarial. O objetivo deste trabalho foi identificar e analisar as relações entre as práticas de Produção mais Limpa e as práticas de Produção Enxuta e seus impactos no desempenho da empresa. Para este objetivo foi proposto a realização de uma pesquisa empírica baseada na triangulação entre dois métodos: estudos de caso múltiplos, contando com 6 (seis) estudos de casos; e uma pesquisa do tipo survey, realizada com 208 (duzentos e oito) indústrias de manufatura brasileiras. Observou-se que há sinergia e complementaridade entre as práticas de Produção mais Limpa e de Produção Enxuta e que estas, empregadas de forma combinada, maximizam o desempenho ambiental, operacional e econômico da empresa. Contudo, observou-se que o desempenho ambiental fomentado pelas práticas de Produção Enxuta é limitado aos aspectos ambientais de consumo de recursos e de geração de resíduos. / The Lean Production and Cleaner Production principles and practices contribute to the values generation with different perspectives. Values are focused respectively on economic sustainability and environmental sustainability, achieved complementarily can contribute to the satisfaction of the stakeholders in a more sustainable way. Studies presents compatibilities between Lean Production and the different Environmental Sustainability approaches, however, few researches have explore empirically the relationship between these constructs, showing a gap to be filled in academia and industry. The objective of this study was to identify and analyze the relationships between Cleaner Production and Lean Production practices and their impact on company performance. For this purpose, it was proposed the accomplishment of an empirical research based on triangulation between two methods: multiple cases studies, with six (6) case studies; and a survey research carried on 208 (two hundred and eight) of Brazilian manufacturing industries. It was noted that there is synergy and complementarity between production practices Cleaner and Lean Production and these, used in combination maximize environmental performance, operational and economic enterprise. However, it was observed that the environmental performance promoted by Lean Production practices is limited to environmental aspects of resource consumption and waste generation.

Contribuições para a análise da efetividade do Programa Município VerdeAzul no âmbito da gestão ambiental paulista / Contributions for an analysis of the effectiveness of the \"Município VerdeAzul\" Program in the context of São Paulo Environmental Management

Machado, Lílian Fernandes 11 June 2014 (has links)
A autonomia dos municípios resultantes da descentralização permite aos governos locais legislar, administrar e executar ações ambientais em seus territórios, entretanto, ainda existe diversas questões que comprometem este processo, como o baixo orçamento destinado à área ambiental e a falta de corpo técnico capacitado. No Estado de São Paulo o Programa Município VerdeAzul (PMVA) tem sido executado com o objetivo de implementar uma agenda ambiental mínima a todos os municípios. Esta agenda auxilia os municípios nas questões ambientais por meio do compartilhamento da responsabilidade da qualidade ambiental entre Estado e municípios; da promoção da descentralização da política ambiental e do fortalecimento da gestão ambiental local. O PMVA acompanha e certifica o desempenho dos municípios através do Índice de Avaliação Ambiental (IAA). Contudo, este acompanhamento acaba sendo focado em uma pontuação geral e na posição alcançada no Ranking Ambiental Paulista, não foi verificado mecanismos para analisar o desempenho ambiental de cada ação e a efetividade do PMVA. Sendo assim, esta pesquisa teve por objetivo desenvolver um conjunto de indicadores para a Avaliação de Desempenho Ambiental (ADA) do PMVA e analisar aplicabilidade deste conjunto para a análise de efetividade do programa. Para isto, foram utilizadas, principalmente, as pesquisa bibliográfica e a documental. A construção dos Indicadores de Desempenho Ambiental (IDAs) foi baseada na ISO 14031 e a coleta de dados foi efetuada nos Planos de Ação dos municípios da UGRHI 13. A analise de efetividade foi realizada a partir dos resultados dos IDAs, o desempenho alcançado em cada indicador foi agrupado em uma escala de efetividade que variou de 0 a 100. A aplicação da ADA apresentou resultados que evidenciam avanços alcançados em relação à estruturação do sistema de gestão ambiental local, ainda que restritos a um contingente pequeno de municípios. A analise de efetividade apresentou resultado parcialmente satisfatório na maioria dos IDAs em 2011 e pouco satisfatório em 2012. Em relação à aplicabilidade da ADA, é possível dizer que esta foi capaz de demonstrar o desempenho ambiental de cada ação analisada e contribuir para a análise da efetividade do PMVA. / The autonomy of municipalities resulting from decentralization allows the local governments to legislate, to administer and implement environmental initiatives in their territory. However, several issues affect this process, as the budget for the environmental area and the lack of trained technical team. In São Paulo, the \"Município VerdeAzul\" Program (PMVA) has been performed with the objective of implementing a minimal environmental agenda to all municipalities. This agenda assists the municipalities in environmental issues by sharing the responsibility of environmental quality between state and municipalities; promoting decentralization of environmental policy and strengthening local environmental management. The PMVA monitors and certifies the performance of municipalities through the Environmental Assessment Index (IAA). However, this monitoring is eventually focused on an overall score and on the position reached in Environmental Paulista Ranking, was not observed mechanisms to analyze the environmental performance of each action and the effectiveness of PMVA. Thus, this research aimed to develop a set of indicators for the Environmental Performance Evaluation (EPE) of the PMVA and analyze the applicability of these indicators for the analysis of program effectiveness. So, was used mainly the literature research and documentary research. The construction of the Environmental Performance Indicators (EPIs) was based on ISO 14031 and the data collection was performed in the Plans of Action of the municipalities of the UGRHI 13. The analysis of effectiveness was performed from the results of the EPIs, the performance achieved in each indicator was grouped on a scale of effectiveness between 0 and 100. The application of the EPE presented results that show progress with respect to the structuring of local environmental management system, though restricted to a small number of municipalities. The effectiveness analysis showed partially satisfactory results in most EPIs in 2011 and somewhat satisfactory in 2012. Regarding the applicability of the EPE, you can tell that this was able to demonstrate the environmental performance of every action analyzed and contribute to the analysis of the effectiveness of PMVA.

Forme d'organisation et profil environnemental de l'exploitation agricole : le cas du secteur laitier / Form of organization and environmental profile of the farm : the case of the dairy sector

Siqueira, Tiago Teixeira da Silva 19 December 2017 (has links)
Cette thèse a pour objectif d’apporter une contribution à l’analyse de la relation entre formes d’organisation et performance environnementale des exploitations agricoles. Elle étudie les liens entre d’une part, la manière dont l’exploitation est organisée et gouvernée et, d’autre part, l’ensemble des pratiques qui fondent son profil environnemental. Elle offre une revue de la littérature économique relative à l’analyse de la performance environnementale des exploitations agricoles et de ses déterminants. Dans le prolongement des propositions théoriques relevant de l’économie néo-institutionnelle et de l’économie évolutionniste, elle propose un cadre analytique de la relation entre formes d’exploitation et profils environnementaux. Ce cadre est appliqué au cas des exploitations agricoles laitières autour de trois chapitres complémentaires, qui combinent à la fois une approche quantitative mobilisant des données du Recensement agricole français de 2010, et une approche qualitative basée sur des monographies d’exploitations réalisées au Brésil. Ainsi, cette thèse contribue à la littérature empirique sur la performance environnementale par son approche systémique et multicritère des exploitations laitières qui permet la construction d’un profil de pratiques agro-environnementales. Dans l’analyse des déterminants de ce profil, elle montre l’importance d’une conception de l’exploitation en tant que système complexe doté d’une structure, d’une gouvernance et d’une capacité d’adaptation propres, et évoluant en interaction avec son environnement externe. La thèse montre enfin qu’il n’existe pas un alignement strict entre formes d’organisation et performance environnementale mais que certaines formes d’exploitation sont plus aptes que d’autres à prendre en compte certaines pratiques agro-environnementales. / This thesis contributes to the analysis of the relationship between farm’s forms of organization and environmental performance. The links between the way in which farm is organized and governed and all the practices related with its environmental profile will be studied. First, the economic literature about environmental performance of farms and its determinants will be reviewed. Based on the insights of the neo-institutional and the evolutionary economics, an analytical framework of the relationship between forms of organization and environmental profiles will be proposed. This framework will then be applied to dairy farms in three complementary chapters. These chapters combine both quantitative approach using data from the French agricultural census of 2010 and a qualitative approach from semi-directive interviews carried out in Brazil. An insight to the empirical literature on environmental performance will be provided thanks to a systemic and multi-criteria approach of dairy farms thought a profile of agro-environmental practices. The analysis of the determinants also shows the importance of studying the farm as complex system with its own structure, governance and adaptability evolving in its external environment. Finally, the thesis bring out that there is no strict alignment between forms of organization and environmental performance. However, certain forms are more apt than others to take into account certain agro-environmental practices.

Monitoring as an instrument for improving environmental performance in public authorities : Experience from Swedish Infrastructure Management / : Experience from Swedish Infrastructure Management

Lundberg, Kristina January 2009 (has links)
Monitoring is an important tool for gaining insight into an organisation’s environmental performance and for learning about the environmental condition and the effectiveness of environmental management measures. Development of environmental monitoring has generally relied on research aiming at improving monitoring methodology, technique or practice within a particular management tool. Little empirical research has taken into account the organisation’s reality where several management tools are used in parallel. This thesis analyses the practice of environmental monitoring in public authorities with the aim of identifying barriers and possibilities for environmental monitoring as an instrument for improving environmental performance, using the Swedish Rail Administration as a case organisation. The study identified two different types of environmental monitoring: environmental performance measurement (EPM) and activity monitoring, both important for achieving environmental improvements. EPM involves gathering and evaluating data to determine whether the organisation is meeting the criteria for environmental performance set by the management of the organisation. EPM can further be used for judging the success and failure of environmental objectives and strategies. Activity monitoring provides each project of the organisation with information to minimise the negative effects on the natural environment or human health and to ensure that the organisation’s operations conform with regulations. Problems encountered comprised a variety of little co-ordinated monitoring activities, poor utilization of the monitoring results as well as limited internal feedback on monitoring results. Some of the problems identified seem to be an effect of the management transition from a traditional ‘command and control’ system to a self-administered organisation managed by economic incentives and voluntary management systems. This thesis suggests several improvements to make monitoring more efficient. Primarily, the monitoring systems must have a clear structure and be adapted to its specific function. The EPE system would benefit from being integrated with the organisation’s central performance measurement, presenting progress towards organisational strategic objectives as well as operational objectives. The system for activity monitoring must not only focus on inputs and outputs to the system but must also include the environmental condition of the system. In order to improve communication and learning, monitoring data within both EPE and activity monitoring must be better transmitted and utilised within the structure of the permanent organisation. Experience from all monitoring activities that now is scattered and inaccessible to the individuals of the organisation could beneficially be stored within a well-structured organisational ‘memory‘. Such a system would facilitate an iterative management process where the monitoring results and the knowledge gained are used for making future plans and projects more adaptive, thereby improving the environmental performance of the organisation. / QC 20100729

The Relation between Corporate Economic and Corporate Environmental Performance

Arndt, Stephanie, Gaitzsch, Gunnar, Gnauck, Carsten, Höhne, Christoph, Hüske, Anne-Karen, Kretzschmar, Thomas, Lange , Ulrike, Lehmann, Katrin, Süss, André 28 December 2011 (has links) (PDF)
For almost 40 years researchers have been trying to identify the relationship between corporate environmental and corporate economic performance. Neither theoretical debate nor empirical studies investigating the relationship show conclusive results. Within a field research seminar at Technische Universität Dresden, nine students conducted a meta-analysis of 124 studies to assess different aspects of the relationship between corporate economic and corporate environmental performance. In the first part of our paper, we analyze and present the theoretical background based on a review of literature. In the second part, we test for empirical evidence. At first, the conceptual frameworks and measurement methods for corporate economic and corporate environmental performance are discussed. We also look at the impact of environmental performance on shareholder value. Thereafter, we examine the influence of time, industries and publication bias. In conclusion, our research indicates that the quality of journals merits further examination to improve results.

Miljöprestanda för lastbilskran : En studieav olika nyttjandescenarier

Lundblad, Nora January 2017 (has links)
Denna kandidatuppsats är en studie av miljöprestandan hos   en lastbilskran satt i relation till användning av en mobilkran.   Miljöprestandan hos lastbilskranen studeras och jämförs med mobilkranens   givet ett visst nyttjandescenario. Miljöprestandan mäts i miljöparametrarna:   klimatpåverkan, energiförbrukning, energieffektivitet samt partikelutsläpp.   Realistiska och mätbara nyttjandescenarier har utarbetats utifrån studiebesök   och intervjuer med Vemservice, Jämtlands Mobilkranar och Curt Sillström   Åkeri. Kandidatuppsatsen är skriven som en del i den miljöstudie som ingår i   utvecklingsprojektet Forskning och utveckling av lastbilars   centralram för minskad miljöpåverkan vid tung transport. Projektet   drivs av Vemservice (Vemdalsservice AB) och syftar till att utveckla   centralramen på en lastbilskran genom att öka dess lyftkapacitet. Projektets   mål är att ersätta mobilkranar med lastbilskranar i en högre utsträckning än   vad som görs idag. I projektet deltar även teknikkonsultföretaget DRIV   Innovation, materialoptimeringstjänsten SSAB Shape samt Mittuniversitetet. En lastbilskran är en lastbil med en kran påmonterad på   flaket, med plats på flaket för att transportera gods. Lyftförmågan hos en   lastbilskran beror både av kranens styrka och själva lastbilens vrid- och böjhållfasthet.   I denna studie har en lastbilskran från Curt Sillströms Åkeri studerats.   Lastbilskranens främsta användningsområden är vid nybyggnationer av   bostäder, flytt av containrar och bodar på arbetsplatser samt vid flytt av   tunga föremål in och ut ur byggnader. Mobilkran kallas det   arbetsfordon som har en lyftkran med svängarm monterad på fordonet, den används inte för transport av gods.   Mobilkranen i denna studie tillhör Jämtlands Mobilkranar och används främst i   lyftarbeten såsom byggande av bostäder och arbeten vid vattenkraftverk. Resultatet   av den studerade miljöprestandan baseras på tre specifika nyttjandescenarior.   Nyttjandescenarierna innefattade att transportera och lyfta en given mängd   gods en given sträcka och tid. Lastbilskranen har högre miljöprestanda än   mobilkranen vid jämförelse i de tre scenarierna, dvs. lägre utsläpp och   mindre energiförbrukning. Den minsta skillnaden i miljöprestanda uppstår när   enbart lyftarbete utförs, då lastbilskranens fulla funktion inte nyttjas då   den ej transporterar något gods. Det troligtvis mest typiska   nyttjandescenariot är att gods både ska transporteras och lyftas. I detta   fall har lastbilskranen flera fördelar tack vare att dess fulla funktion   utnyttjas. / This bachelor thesis is a study of the environmental performance of a loader crane in relationship to the usage of a mobile crane. The environmental performance of the loader crane is studied and compared to the mobile cranes performance given a set of specific user scenarios. The environmental performance is measured using the following environmental parameters:climate impact, energy consumption, energy efficiency and particle emissions. Realistic and measurable user scenarios were prepared using information from visits and interviews with Vemservice, Jämtlands Mobilkranar and Curt Sillström Åkeri. The thesis is written as a part of the environmental study that is included in the developmental project “Forskning och utveckling av lastbilars centralram för minskad miljöpåverkan vid tung transport”. The project is managed by Vemservice (Vemdalsservice AB) and the purpose of the project is to develop the frame on a loader crane by increasing the capacity for lifting. The goal of the project is to replace mobile cranes with loader cranes to a higher degree than what is currently the case. The projects participants are also made up by the technology consulting DRIV Innovation, SSAB Shape and also Mid Sweden University. A loader crane is a truck with a crane mounted on its flatbed and also room on the flatbed for the transport of goods. The lifting capabilities of a loader crane is dependent on the strength of the crane and the rigidity of the frame of the truck itself. In this thesis, a loader crane from Curt Sillström Åkeri AB is studied. The main usage of the loader crane in this study is in construction, the moving of work site sheds and in the moving of heavy objects in and out of houses. A mobile crane is a work vehicle with a crane and swing arm mounted on the back of the vehicle. The mobile crane in this study belongs to Jämtlands Mobilkranar and is primary used for heavy lifting in construction and work at a hydro power plant. As opposed to the loader crane, the mobile crane is not used for the transport of goods. The resulting environmental performance was based on three specific user scenarios. The user scenarios consisted of lifting and transporting a given amount of goods for a specified distance and time. When a comparison is made between the loader crane and mobile crane for total emissions and energy consumption in each user scenario, the loader crane has a larger environmental performance. The smallest difference in environmental performance arises when lifting is the only work being done, due to the fact that the full capacity of the loader crane is not utilized since it is not used to transport goods. Likely the most typical user scenario consists of goods being both transported and lifted. In this case the loader crane has a number of advantages because its full capacity is being utilized. / <p>2018-02-01</p>

From the theoretical perspective, this study aimed to do a review of previous researches, for those in favor or against of the involvements of firms to address the social and environmental issues. This study analyzed the theme of CSR under the perspective of the corporate management evolution model, which started from a philanthropic model to what we see today as an important strategic decision tool. The climate change, caused by the global warming has been driven the evolution of the CSR model. From the empirical perspective, the main goal was to investigate the correlation between firm’s financial performance and social/environmental performance for Brazilian companies from 2001 to 2007, using available information provided by the Braziian Institute of Social and Economic Analysis (IBASE). Two types of panel data econometric models were used. The fixed effects model was used to investigate the existence of correlations between the financial indicators and the social/environmental indicators. Additionally, a panel data IV model was used to investigate causality and try to answer the question whether the social/environmental performance has a positive or negative impact on the firm’s financial performance. Results show a positive relationship between corporate social/environmental performance and financial performance. The internal social investment is the most relevant social/environmental variable in this result, since it is positively correlated with the financial performance indicator represented by the variable return on assets (ROA). The causality analysis showed also that the internal social investment has a positive effect on the corporate financial performance. / A proposta deste trabalho é ampliar o estudo sobre o tema da Responsabilidade Socioambiental Empresarial tanto no panorama teórico como também no empírico. No contexto teórico, este estudo procurou fazer uma revisão das argumentações tanto contrárias como a favor de um comportamento social e ambientalmente mais responsável por parte das empresas. Foi realizada uma análise da evolução do modelo de gestão das empresas, que cada vez mais passa a incorporar as questões sociais e ambientais na agenda das decisões estratégicas. Esta evolução tem sido motivada principalmente pelos problemas ambientais causados pelo aquecimento global.
