This diploma thesis deals with the topic of principles of international climate change law. At the beginning of the thesis the issues relating to principles in general and their role in environmental law is briefly described. Then the topic of international regulation of climate change is presented in brief, including the analysis of actual conditions and a summary of the current situation. The next chapter in detail deals with the various principles which may be found in the international climate change law and its protection and which are typical for this area. Primarily, these principles include the principle of common but differentiated responsibilities, the principle of precaution, the principle of cooperation and sustainable development, and also other principles are briefly mentioned. The particular principles are at first introduced in general and subsequently their effects in the climate regulation area are analyzed, including also a brief evaluation of the principles and outline of the recent situation. Furthermore, certain de lege ferenda notions are introduced when appropriate.

A partir da Política Nacional sobre Mudança do Clima, o Brasil tem publicado inúmeras leis sobre mudança do clima, mas tem-se verificado dificuldades em sua aplicação. Apesar disso, pouco se tem escrito com o objetivo de identificar os aspectos mais críticos que permitam auxiliar a revisão e aprimoramento do marco jurídico-climático no país. O objetivo principal deste estudo foi realizar uma análise crítica da Política Nacional sobre Mudança do Clima e da Política sobre Mudança do Clima do Estado de São Paulo, a fim de avaliar se o processo de incorporação da dimensão climática no ordenamento jurídico brasileiro, e em especial no Estado de São Paulo, tem sido adequado e, em caso negativo, porque não. Foram identificadas e estudadas mais de 100 leis no Brasil sobre mudança do clima, mas a análise crítica na dissertação limitou-se à lei nacional e paulista sobre mudança do clima. Também foi estudada a bibliografia principal sobre o assunto e foi realizado estudo de casos já levados ao Poder Judiciário. Os resultados da análise permitem verificar que as principais falhas dos marcos legais em nível nacional e estadual apontam para a ausência de clareza na alocação de responsabilidades dos setores envolvidos. Além disso, a legislação paulista adotou uma meta de redução de emissões que tem se mostrado inatingível, o que gera insegurança jurídica e prejudica a eficácia das normas. Finalmente, recomendações são apresentadas para o aprimoramento dos marcos legais. / Since the Brazilian National Climate Change Policy was enacted, Brazil has been issuing many laws on climate change, but implementation of such laws has not been adequate. Nevertheless, there are very few legal assessments on the Brazilian climate change regime that could assist to improve its effectiveness. The main purpose of this masters dissertation is to undertake a critical assessment of Brazilian National Climate Change Policy and of State of São Paulo Climate Change Policy, in order to comprehend whether or not the process of incorporating the climate change dimension on the Brazilian legal system has been adequate, and if not why. More than one hundred laws on climate change in Brazil were researched, but the detailed assessment was limited to the National and State of São Paulo legislation. Court precedents and main doctrine have also been analyzed. The results of the assessment demonstrate that since the National Climate Change Policy, many other climate change laws have been enacted, and most of them present serious uncertainties, which impair the execution of these laws. The main uncertainties of such laws arise from the fact the they do not clearly allocate responsibility and obligations to all stakeholders involved. Besides, the state law adopted a reduction target that is not achievable, which cause legal uncertainty and impairs the execution of these laws. In the end, the dissertation presents recommendations for the improvement of Brazilian climate change legal regime.

The Swedish government is legally obliged to conduct climate policy work that will protect nature and humanity from the harmful effects of climate change. Obligations related to the environment arise under Swedish domestic law, European law and international law. This thesis investigates the possibilities for the Swedish public to initiate climate change litigation against the Swedish government due to insufficient climate actions. I examine three climate change litigation approaches from selected jurisdictions, including Germany, the Netherlands, Norway and the United Kingdom. By transposing the three litigation approaches into the Swedish legal order I seek to discuss the possibilities for the public to challenge the Swedish state's responsibility in climate matters. This thesis claims that the possibilities for the concerned public to address climate change are restricted. International obligations derived from the European Convention on Human Rights and the Aarhus Convention have given individuals substantive rights and procedural rights in matters related to the environment. However, the implementation of the international obligations are not always enshrined in the national law.

The first chapter of this thesis discusses the recent development of climate change law. It explores the reason as to why it is at the centre of a global debate, which is predominantly due the increasingly pronounced consequences of climatic changes on human society and the environment. Furthermore, it describes the most important requirements in tackling the issues presented by international climate change treaties. This includes the United Nations Framework Convention on Climate Change, acting as a base for the whole international climate change regime, the Kyoto Protocol as a legal tool with specified emission targets and most recently, the Paris Agreement, which serves as an independent international treaty however is still under the guidance of the framework convention. The author predicts that the Paris Agreement will determine the future direction of this legal field and therefore puts particular focus on this treaty in the first chapter of the thesis. The paper aims to uncover its weaknesses - questioning the enforceability of some of the measures that rely on the autonomy of states to implement and the lack of ambition in some of its targets. The second chapter expands on one of the key issues related to the main topic. The author emphasizes how the importance of environmentally friendly...
