The Court drew on IPCC reports and the EU NDC to determine that the Czech Republic must take measures to reduce its emissions by 55% by 2030 compared to 1990 levels (<a href=\"https:\/\/www.klimazaloba.cz\/wp-content\/uploads\/2022\/07\/Czech-Climate-Litigation-Full-Judgment-in-English.pdf\">Opinion, unofficial translation, paragraph 251<\/a>). The court\u2019s decision adds to a list of successful climate ambition cases that began with the Netherlands\u2019 <a href=\"https:\/\/www.urgenda.nl\/wp-content\/uploads\/ENG-Dutch-Supreme-Court-Urgenda-v-Netherlands-20-12-2019.pdf\"><em>Urgenda <\/em>decision<\/a> in 2007. These cases, and pending cases in <a href=\"http:\/\/climatecasechart.com\/non-us-case\/kim-yujin-et-al-v-south-korea\/\">South Korea<\/a>, <a href=\"http:\/\/climatecasechart.com\/non-us-case\/la-rose-v-her-majesty-the-queen\/\">Canada<\/a>, the <a href=\"http:\/\/climatecasechart.com\/non-us-case\/youth-for-climate-justice-v-austria-et-al\/\">European Court of Human Rights<\/a>, and <a href=\"http:\/\/climatecasechart.com\/non-us-case\/a-sud-et-al-v-italy\/\">Italy<\/a>, face down a daunting question: what is a country\u2019s \u201cfair share\u201d of effort to combat climate change?<\/p>\n<p><!--more--><\/p>\n<p>The \u201cfair share\u201d question is difficult to answer because it requires a court to translate broad principles into a country-specific quantitative assessment of emissions reduction. Countries that signed the Paris Agreement have a duty to mitigate their emissions in order to keep global warming below 2\u00b0C, but that duty is not identical for each country. Principles of international environmental law such as equity and common but differentiated responsibilities (CBDR), adopted by the Paris Agreement and other international climate declarations, place a heightened duty on developed countries to combat climate change. Yet, these principles do not spell out to what extent a developed country\u2019s \u201cfair share\u201d of effort is greater than the effort required by an average country (<a href=\"https:\/\/www.cambridge.org\/core\/journals\/leiden-journal-of-international-law\/article\/abs\/fairness-equity-and-justice-in-the-paris-agreement-terms-and-operationalization-of-differentiation\/4AD4C512175ECFC80F14083BDAB4CA1A\">Will and Magner-Nestler<\/a>).<\/p>\n<p>Courts, litigants, and scholars have taken various approaches to fill this gap. In <em>Urgenda<\/em>, the Supreme Court of the Netherlands reasoned that even though reducing the Netherlands\u2019 emissions would have little effect on a global scale, it is still responsible for its fair share. Lauded as a courageous decision, <em>Urgenda <\/em>laid the foundation for future ambition lawsuits by rejecting the drop-in-the-bucket argument and using climate science and international agreements to impose a specific emissions mitigation obligation on the Netherlands (<a href=\"https:\/\/brill.com\/view\/journals\/jeep\/17\/3\/article-p307_307.xml\">Backes and van der Veen<\/a>).<\/p>\n<p>In <a href=\"http:\/\/climatecasechart.com\/non-us-case\/kim-yujin-et-al-v-south-korea\/\"><em>Do-Hyun Kim et al. v. South Korea<\/em> (pending)<\/a>, the plaintiffs argue that South Korea must adopt a more ambitious climate target based on a comparison to global averages. The plaintiffs calculated how much global emissions targets must decrease, in aggregate, to keep warming below 2\u00b0C. South Korea is especially obligated to reduce its emissions, since its per capita CO2 emissions are 2.7 times higher than the global average and its historic emissions are the 16<sup>th<\/sup> highest in the world. The plaintiffs concluded that South Korea should reduce its emissions target by at least as much as the necessary global average reduction, which would still require South Korea to adopt a more ambitious emissions target (<a href=\"http:\/\/climatecasechart.com\/wp-content\/uploads\/sites\/16\/non-us-case-documents\/2020\/20200515_NA_complaint.pdf\">Do-Hyun Kim Supplemental Complaint page 59<\/a>).<\/p>\n<p>Scholars and organizations such as Climate Action Tracker (CAT) have developed a sophisticated burden-sharing <a href=\"https:\/\/climateactiontracker.org\/methodology\/cat-rating-methodology\/fair-share\/\">methodology<\/a> to assign a fair share to each country. The first step in this approach is to assign a \u201cfair share range\u201d to each country based on the available effort-sharing literature, including IPCC reports. Next, CAT determines where on the range a country\u2019s current climate target lands. Finally, assuming that every country\u2019s target will fall on the same place on its range, CAT calculates the level of temperature change that would result. <a href=\"https:\/\/www.tandfonline.com\/doi\/full\/10.1080\/14693062.2021.1970504\">Professor Lavanya Rajamani<\/a> and others has refined this analysis, distinguishing effort-sharing methodologies that accord with international law and those that do not to create more accurate fair shares. The plaintiffs in <a href=\"http:\/\/climatecasechart.com\/non-us-case\/a-sud-et-al-v-italy\/\"><em>A Sud et al. v. Italy<\/em><\/a> relied on a report of Climate Analytics, one of CAT\u2019s parent organizations, in their complaint. The plaintiffs in <a href=\"http:\/\/climatecasechart.com\/non-us-case\/youth-for-climate-justice-v-austria-et-al\/\"><em>Duarte Agostinho and Others v. Portugal and 32 Other States<\/em><\/a>, before the European Court of Human Rights, also relies on CAT\u2019s analysis to define fair share for 32 members of the EU.<\/p>\n<p>While it remains to be seen whether the courts will side with the plaintiffs in these pending cases, the decision in the recent <em>Czech Republic <\/em>case is an encouraging sign because it accepted the binding nature of the Paris Agreement, found that climate change interferes with individuals\u2019 rights, and because it engaged in transjudicial dialogue.<\/p>\n<p>The Municipal Court of Prague found that the Paris Agreement Article 4(2) imposes an obligation on the Czech Republic to implement mitigation measures aimed at achieving its NDC (paragraph 248). The Czech Republic never established an NDC of its own, but the court determined that the EU-wide NDC requiring a collective 55% reduction in greenhouse gas emissions by 2030 must be interpreted to apply to individual EU members including the Czech Republic, since the Czech Republic is a direct participant in the Paris Agreement (paragraph 251). Therefore, the court ordered Czech Ministries to take mitigation measures to reduce greenhouse gas emissions by 55% by 2030, compared to 1990 levels (paragraph 328). The court also enjoined the Czech government from continuing to interfere with the plaintiffs\u2019 rights. The Czech Constitution and the EU\u2019s Charter of Fundamental Rights and Freedoms create a right to a favorable environment. The court interpreted this right to mean a right to live in climatic conditions \u201cwhich allow the unhindered exercise of the needs of human life\u201d (paragraph 213). The court found that this right was interfered with by the consequences of climate change, pointing to specific findings in the IPCC Sixth Report which describe climatic conditions in Europe. Even though the worst consequences of climate change have not occurred, any finding of a change for the worse can establish interferences (paragraph 223). The Czech Court also cited the Netherlands\u2019<em> Urgenda <\/em>decision and the United States Supreme Court\u2019s decision in <em>Massachusetts v. EPA<\/em>.<\/p>\n<p>The Decision in <em>Klimatick\u00e1 \u017ealoba \u010cR v. Czech Republic <\/em>was a major victory for the climate and a valuable precedent for similar cases in Europe and around the globe. Even though the opinion of one national court is not binding on others, the Czech court\u2019s engagement with <a href=\"https:\/\/twitter.com\/sarahlesliemead\/status\/1550377528510087170?s=27&amp;t=QHUJ9AgUbOROWWfomyOSAA\">transjudicial dialogue<\/a> may encourage judges in the pending cases to draw on decision form other jurisdictions as well. Since climate change requires a global solution, transjudicial dialogue will be pivotal to mitigating climate change equitably and effectively.<\/p>\n<p>* This blog post\u00a0was edited by\u00a0<a href=\"https:\/\/climate.law.columbia.edu\/directory\/maria-antonia-tigre\">Maria Antonia Tigre<\/a>.
