The Climate Action Tracker`s Fair Share evaluation system is based on the publication of the scientific literature on what a country`s overall contribution should be to make a fair contribution to the implementation of the Paris Agreement. To contribute equitably to the goals of the Paris Agreement, developed countries must both achieve national emission reductions and help the poorest countries reduce their emissions. This means that the entire NDC NDC area of action is the total amount of national reductions and emission reductions abroad (climate finance, provision of resources or the introduction or purchase of emission units if they are in turn discounted in the host country). Thus, the NDC emission reduction range estimated by the CTU would almost always be simated by a developed country to provide sufficient climate funding, or support through other means of implementation to reduce that country`s overall contribution to reducing emissions to the “fair” level required. The effort-involved studies in the CAT database include more than 40 studies used by the IPCC (Chapter 6 of WG III and Huhne et al. (2013) as well as additional analyses carried out by the CTU to complete the data set. They cover very different views of what might be right, including considerations of justice such as historical responsibility, capacity and equality. We take into account the results of studies consistent with the previous target of 2oC, as well as the 1.5oC limit in the Paris Agreement, in order to cover the full range of historical perspectives and developments in long-term temperature targets. Commits to reduce emissions by 29% for agriculture, 31% for energy and 21% for forests and land use by 2030, compared to a business as usual scenario. That`s an average drop of 27%. This is linked to international aid, although about 40% of them can be filled unconditionally.
Contains a section on adaptation, but only for the period 2015-2020. In the run-up to the adoption of the Paris Agreement in 2015, more than 160 countries and the European Union have publicly outlined the measures they intend to take under the Global Compact, known as the Intended Nationally Determined Contributions (INCS). A country`s INDC is transformed into the NDC if it formally adheres to the Paris Agreement by tabling an instrument for ratification, acceptance, approval or membership, unless a country decides otherwise. In September 2020, 186 contracting parties submitted their plans to the NDC register. In our evaluation, we gathered a wide range of literature on what different researchers would view from many angles as a “fair” contribution to greenhouse gas reduction. In accordance with the Paris Agreement adopted in December 2015, INDC will be the first national contribution (CNN) when a country ratifies the agreement, unless it decides to present a new CNN at the same time.
