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.

Cidades e áreas urbanas são vulneráveis aos impactos das mudanças climáticas. Governos locais e subnacionais desempenham um papel importante na implementação de políticas públicas de enfrentamento dessas mudanças. Referenciado no debate internacional, este artigo investiga os principais fatores que apoiam, limitam e facilitam a implementação de medidas de mitigação e adaptação às mudanças climáticas em áreas urbanas. Por meio da análise de 38 estudos de caso de diferentes regiões do mundo, busca-se ir além da análise de contextos específicos e realidades restritas, capturando o repertório de estratégias que vem sendo adotado por governos locais e subnacionais de países desenvolvidos e em desenvolvimento. Identificam-se três grupos de fatores que apoiam e limitam essas ações: recursos e capacidades; conhecimento e informação e instituições e governança.Cities and urban areas are vulnerable to the impacts of climate change. Subnational and local governments play an important role in implementing public policies to cope with these changes. Referenced in the international debate, this paper investigates the main factors that support, limit and facilitate the implementation of mitigation and adaptation to climate change in urban areas. Through the analysis of 38 case studies from different regions of the world, it seeks to go beyond the analysis of specific contexts and restricted realities, capturing the variety of strategies being adopted by local and subnational governments in developed and developing countries. The paper identifies three groups of factors that support and limit these actions: resources and capacities, knowledge and information and institutions and governance.

The purpose of this paper is to undertake a critical evaluation of the Kyoto Protocol. The evolution of the discussions that produced the final document is sketched through the analysis of official documents of the United Nations Framework Convention on Climate Change (UNFCCC), relevant papers and material from the press. We also discuss the factors that cast doubts on the continuation and feasibility of the Protocol and the prospects for the post-Kyoto period and a new compromise.O objetivo deste trabalho é fazer uma avaliação crítica do Protocolo de Quioto. Descreve-se inicialmente a evolução das discussões que produziram o documento final, utilizando como fontes documentos oficiais da Convenção-Quadro das Nações Unidas para Mudança do Clima (CQNUMC), artigos importantes e material jornalístico. Enfatizam-se a seguir os fatores que colocam em dúvida a continuidade e a factibilidade do Protocolo. Discutem-se em último lugar as expectativas para o período pós-Quioto e para um novo acordo.

Este trabajo se plantea a partir la ecología política y la filosofía de la liberación, con el objetivo de presentar una crítica a los Acuerdos de Cambio Climático en París 2015, dada la poca o nula efectividad de las políticas ambientales que se proponen. Para tal fin, se realizó un ensayo teórico crítico al modelo capitalista vigente y sus conflictos frente al desarrollo sostenible. La metodología utilizada es un ensayo crítico a la contradicción producción-tecnología que el capitalismo plantea a la civilización y a la humanidad. Los resultados indican que existen conflictos entre las políticas ambientales especificadas en dicho Acuerdo de Cambio Climático firmado, en función de su efectividad para la humanidad y la naturaleza, como reproducción ampliada del capital versus vida. The objective of this paper is to start from the political ecology and the philosophy of the liberation, to present a critique to the Agreements of Climatic Change in Paris 2015, given the little or null effectiveness of the environmental policies that are proposed. For this purpose, a critical theoretical essay was carried out on the current capitalist model and its conflicts regarding sustainable development. The methodology used is a critical test to the productiontechnology contradiction that capitalism poses to civilization and humanity. The results indicate that there are conflicts between the environmental policies specified in said signed climate change agreement, based on their effectiveness for humanity and nature, such as an expanded reproduction of capital vs. life.

Climate change became the center of public concern in the last years. Cities and urban areas are particularly vulnerable to the effects of climate change. Half of the global population currently lives in urban areas and by 2050 this proportion is estimated to increase. In addition, more then 80 percent of the cities are located on the shore and near rivers, making them predisposed to increased storms, floods and sea-level rise. Local governments play an important role in implementing climate change policies. The empirical evidence shows that local governments often appear as key actors in coordinating, facilitating and implementing climate change actions alone or cooperating with an array of different actors. This paper reviews the literature on cities and climate change and explores the elements that enable local governments to take action in terms of climate adaptation. It also discusses the risks and vulnerability of cities looking at the implementation of climate change adaptation strategies. Enabling elements such as good governance, democratic and participatory institutions, availability of different types of resources, knowledge and information on what and how to adapt, as well as the presence of a local political entrepreneur often appear supporting climate change adaptation.

O objetivo deste artigo é lançar luzes sobre as implicações da mudança climática para as organizações. Para fazer frente a esse debate, são explorados: o conceito de "inteligência ambiental" (IA); as estratégias por meio das quais as organizações fazem frente ao desafio da mudança climática; as oportunidades que explicam a adoção dessas estratégias; e o papel fornecido pela função produção para que tais estratégias possuam o efeito desejado. Por fim, tais conceitos são sistematizados, buscando-se uma integração dos modelos teóricos existentes, até então considerados de maneira estanque.The aim of this paper is to enlighten the implications of climate change for organizations. To deal with this subject, the follow issues are analyzed: concept of environmental intelligence; opportunities which justify the adoption of these strategies, and the main role performed by the production function to implement such strategies. Finally, concepts of prior theoretical models are taken into account.

Neste artigo, discuto, principalmente, a inserção dos gastos públicos em modelos de mudança climática. Considero a análise de Kemfert, Lise e Tol (2004) como exemplo de modelo formal que agrega as questões econômicas e climáticas, e amplio a discussão com o estudo da inserção dos gastos públicos com gestão ambiental e da matriz energética. Mostro que as estruturas econômicas e físicas dos países estabelecem diferentes gastos públicos, com diferentes impactos ambientais e conseqüências para outras nações e isto afeta sobremaneira os resultados de qualquer modelo econômico. Em termos dos gastos públicos com meio ambiente, observo especificamente o caso brasileiro, verificando os gastos públicos federais com Gestão Ambiental no Brasil de 2000 a 2006. Defendo a importância de se considerar as diversas possibilidades de despesas públicas com gestão ambiental, para o tratamento das questões relativas à mudança climática.In this paper, I, mainly, analyzed the inclusion of environmental budget in climate change models. Considering Kemfert, Lise and Tol (2004)'s approach to show a formal model that puts together economic and climate issues, I analyzed the inclusion of environmental public spending and energy. I tried to show that countries' economic and physical structures establish different public spending, with different environmental impacts and consequences to another nations and that has strong influence on economic models. In relation to public spending, I considered, specifically, the Brazilian federal budget to Environmental Management from 2000 to 2006. In this article, I argue in defense of considering budget for environmental management in the discussion on climate change.

Abstract This article argues for the need to address the fact that a large amount of conflict over environmental knowledge occurs inside the academy, against the commonsensical perception that it is a mark of the relationship between science and non-science. It proposes a conceptual speculative exercise that uses a framework presented by indigenous ethnology, specifically the theory of Amerindian perspectivism, to address tensions among scientific disciplines in interdisciplinary work. Ethnographic vignettes about contentious encounters between climatologists/meteorologists and social scientists are used as methodological and analytical resources. The paper argues for a non-platonic approach to interdisciplinarity, suggesting that a more productive and realistic attitude treats the collaboration of different disciplines as a case of alliance among “enemies”, with the caveat that the concept of enemy should be understood here in terms of the relational philosophies of Amerindian peoples, where antagonistic difference is valued for its constitutive and productive effects on reality.
