Fighting climate change in the air: lessons from the EU directive on global aviation

The European Union's (EU) decision to include aviation into the Emissions Trade Scheme was heatedly contested. Countries around the world, but mainly the Brazil, Russia, India, China and South Africa group (BRICS) and the US, denounced the EU's initiate as illegal and unilateral. Following a decade of frustrated negotiations at the International Civil Aviation Organization (ICAO), this paper interrogates why such measure, in principle climate-friendly, inspired so much global resentment. I argue that concerns with competitiveness and risks of legal inconsistency are important, but insufficient elements to explain the core of the conflict. The paper suggests that the EU was strongly criticized because third countries perceived this action as an imposed solution, which fostered an environment of distrust. Therefore, I claim that the problem has more to do with a normative divide than with a substantive divergence on what should be done regarding aviation emissions. My analysis is informed by the present literature on the links between trade and climate change, but gives particular weight to first-hand information through interviews with key stakeholders. The paper is divided in three parts. First, it presents the scope of the EU directive in historical perspective. Second, it explores the EU's measure through three different angles: legal, economical and political. The final part explores some possible solutions to overcome these divergences.

Dilemma of choice: China's response to climate change

In recent years, erratic global climate conditions have generated an incessant series of natural disasters in China. This article seeks to explore China's climate change policies. This article addresses the impacts of climate change on China's environment and China's perception, principle, objective and policy actions in response to climate change.

The contribution of the European Union to global climate change governance: explaining the conditions for EU actorness

Como organização regional, o papel da União Europeia na governança global do clima enfrenta obstáculos que não se aplicam a nenhuma outra parte da Convenção-Quadro das Nações Unidas sobre a Mudança do Clima (CQNUMC) e do Protocolo de Quioto. Avaliando essa singularidade, este artigo fornece uma analise teórica e empírica de como os elementos de actorness (reconhecimento, capacidade, oportunidade e coesão) definem a participação da UE no regime internacional de mudanças climáticas.

The Brazilian position on forests and climate change from 1997 to 2012: from veto to proposition

This article describes the Brazilian position on forests and climate change from 1997 to 2012. It argues that it has evolved from a veto, which excluded from the climate change regime emissions from the conversion of native forests, to a proposition, as Brazil offered its approach to the international community. It explains the change with domestic developments: governance over deforestation, the emergence of new and relevant actors, and presidential diplomacy.

Governance of global climate change in the Brazilian Amazon: the case of Amazonian municipalities of Brazil

With regards to the debate about governance of climate change, it should be assumed that the Amazon region plays an important role, as this large area is highly vulnerable to its effects. In this sense, this article aims to discuss how some Amazonian municipalities of Brazil have been taking part in the complexes and multilayered processes of climate governance.

Organizational and accounting change within the context of the environmental agenda: evidence from Portugal

Purpose – The purpose of this paper is to explore the process of organizational change undergone by a large Portuguese business group within the context of the environmental agenda and the role of accounting as a mechanism for change. Design/methodology/approach – The paper reports the results of a case study conducted between 2006 and 2009. Information was obtained from semi-structured interviews and secondary sources. Organizational changes were analyzed using Laughlin’s model in order to identify which category reflected most of the changes introduced to address environmental matters. Findings – This paper offers evidence that change is not a homogeneous phenomenon. Additionally, it confirms previous studies’ findings which found that accounting did not play a significant role in the process of organizational change within the context of the environmental agenda. Originality/value – This paper seeks to complement the research in this area by integrating observations from a case study into an existing model of levels of organizational change according to how a Portuguese business group incorporated environmental issues into its processes, policies and corporate culture.

Modelos de regressão para estimação do volume de árvores comerciais, em florestas de Paragominas

Em fevereiro de 2009, o Ministério do Meio Ambiente criou a Resolução CONAMA 406, que determina que, a partir do segundo Plano Operacional Anual (POA), só será aceito, pelo órgão ambiental competente, o cálculo do volume de árvores em pé, mediante equação de volume, desenvolvida especificamente para o Plano de Manejo Florestal Sustentável (PMFS). Em função disso, necessita-se especificar um modelo estatístico para estimar o volume comercial das árvores. Neste trabalho, ajustou-se o modelo estatístico às informações coletadas em povoamento de floresta Ombrófila densa, localizada no município de Paragominas, Estado do Pará, com o objetivo de selecionar o de melhor ajuste e precisão. A amostra foi composta de 234 árvores, distribuídas em sete classes diamétricas, com amplitudes de 12 cm, no intervalo de 49 até 127 cm. Obteve-se o volume real, medindo-se as circunferências nas secções, a cada 2 m, determinando-se o CAP e a altura comercial real. A seleção para a escolha do melhor modelo teve como referência o valor da estatística F, o mais alto coeficiente de determinação (R²), o menor erro padrão da estimativa em percentagem (Syx%) e a análise de resíduos, por meio do Desvio Médio Porcentual (DMP). Com base nas estatísticas mencionadas, concluiu-se que o melhor entre os modelos tradicionais, a ser empregado na área, foi o proposto por Schumacher-Hall. Finalmente, concluiu-se que o modelo alternativo, com variável dummy, é melhor e deve ser o adotado em florestas nativas da Amazônia.

The strategic management of creation process and of change: a theoretical contribute from the perspective of tourism

The entrepreneurship and innovation have been gradually gaining ground in the academic community as a field of study. However, the interpretations surrounding fragmented, without a univocal definition. In last decades, tourism has received greater attention from researchers in various sciences, varying only by the different emphases considered: economic, social, cultural and environmental. As other emerging sectors in a modern economy, tourism is a dynamic and ever-changing industry. The study has as purpose to provide a better understanding regarding the essence of entrepreneurship: theoretical and practical implications from the perspective of tourism. Regarding the methodology used here, this is a conceptual paper with a literature review that brings together the major components of entrepreneurship and its implications tourist perspective and conceptual model of the dynamic nature of the Triggering Process and innovation (e.g. iTravey, Interactive Stores, Tourist Transportable Tower).

Interação entre volume de vaso e competição com plantas daninhas sobre o crescimento da soja

RESUMO A avaliação dos efeitos da competição das plantas daninhas sobre o crescimento da soja é efetuada por meio de ensaios em ambientes protegidos. Esses ensaios, geralmente, são feitos em recipientes (vasos) em que se testam os efeitos desejados em diferentes épocas de coleta. O tamanho (volume) dos vasos a ser escolhido depende do tipo de estudo, da espécie-teste e das variáveis que serão estudadas. Por esta razão, objetivou-se com este trabalho avaliar o efeito do tamanho de vasos na habilidade competitiva da soja com as plantas daninhas Urochloa brizantha e Bidens pilosa. O experimento foi conduzido em casa de vegetação e o delineamento foi em blocos ao acaso, em esquema fatorial 3 × 5, com quatro repetições. Os fatores considerados no experimento foram três sistemas de competição (soja cultivada isoladamente, soja + U. brizantha e soja + B. pilosa) e cinco volumes dos recipientes (2, 4, 7, 10 e 16 dm3). O crescimento das plantas de soja foi afetado tanto pelo volume dos vasos quanto pela competição com U. brizantha e B. pilosa, sendo que U. brizantha foi mais competitiva com a soja. Vasos com maiores volumes aumentam os efeitos da competição sobre o crescimento da soja.
