The study aims to determine each country&#039;s fair share of greenhouse gas emissions with a view to achieving the Paris Agreement&#039;s goals of limiting global warming to 1.5\u00b0C or 2\u00b0C.<\/p>\n<p>Key points of the study:<\/p>\n<ul>\n<li><strong>Fair distribution of effort:<\/strong> International climate negotiations have long debated the fairness of the distribution of efforts to achieve common global goals. The study&#039;s framework is based on the principles of fairness, as well as the principles of harm prevention, precaution, polluter-pays, ability to pay, and past-due benefits.<\/li>\n<li><strong>Global warming budget:<\/strong> The study defines a global warming budget that includes all anthropogenic greenhouse gases and allocates it to individual countries. This approach differs from previous studies that focused only on CO2 emissions. The GWP* metric is used to convert non-CO2 greenhouse gases into CO2 equivalent emissions.<\/li>\n<li><strong>Three interpretations of justice:<\/strong> The study presents three interpretations of the principles of justice:\n<ul>\n<li><strong>Interpretation I:<\/strong> Equality and the &quot;polluter pays&quot; principle, where every person is given the same right to pollute, but the country&#039;s historical emissions since 1850 or 1990 are taken into account.<\/li>\n<li><strong>Interpretation II:<\/strong> It takes into account the ability to pay using indicators such as government bond yields (II-A) and GDP per capita (II-B), which adjusts the distribution based on Interpretation I.<\/li>\n<li><strong>Interpretation III:<\/strong> Instead of ability to pay, it takes into account the \u201cbeneficiary pays\u201d principle, which uses historical fossil fuel sales to adjust Interpretation I allocated budgets.<\/li>\n<\/ul>\n<\/li>\n<li><strong>Budget exhaustion:<\/strong> The analysis shows that by 2021, many countries, including most developed countries, will have already exhausted their fair share of the warming budget compatible with the 1.5\u00b0C target. The situation is similar for the 2\u00b0C target. For example, the US, the UK, Russia and Japan are among the countries with negative remaining budgets. In contrast, countries such as India and Brazil still have most of their budget available.<\/li>\n<li><strong>Differences between fair budgets and reductions:<\/strong> The study shows a significant gap between the fair budgets allocated to countries and the deepest possible domestic emission reductions they can achieve. Many countries with high levels of human development will need to take action beyond domestic reductions to achieve their fair share.<\/li>\n<li><strong>Impact of regulatory decisions:<\/strong> The results are influenced by normative decisions such as the choice of equity principles, indicators and base year for calculating historical emissions. For example, when taking into account the \u201cability to pay\u201d or \u201cbeneficiary pays\u201d principle, differences between countries increase.<\/li>\n<li><strong>Uncertainties and methodological factors:<\/strong> The study also takes into account methodological and physical uncertainties, such as the estimate of the aerosol masking effect, the range of adjustment of the indicators, and the warming target. However, the impact of these factors is less significant than the normative decisions.<\/li>\n<li><strong>Additional measures:<\/strong> Given the budget overruns of many countries, the study highlights the need for complementary measures such as large-scale carbon dioxide removal (CDR) and international cooperation through financial support and technology transfer.<\/li>\n<\/ul>\n<p>The study provides a valuable framework for understanding and assessing countries&#039; fair contributions to addressing climate change. It identifies gaps between fair ambition and reality and highlights the need for transnational cooperation. It is also important to note that the study does not take into account the costs of climate change mitigation and the damages caused by climate change, which is important for future studies. <em><strong>Spring<\/strong><\/em><\/p>","protected":false},"excerpt":{"rendered":"<p>The document presents a principled framework for determining the fair contributions of individual countries to warming under the Paris Agreement.
