Sharon Dijksma, Dutch Environment Minister and President of the Council, and Maroé Efsovic, Vice-President of the European Commission, sign the agreement on behalf of the EU at a high-level ceremony in New York, USA. National communication reports often cover several hundred pages and cover a country`s actions to reduce greenhouse gas emissions, as well as a description of its weaknesses and effects of climate change.  National communications are established in accordance with guidelines adopted by the UNFCCC Conference of Parties. Contributions (planned) at the national level (NDC), which form the basis of the Paris Agreement, are shorter and less detailed, but also follow a standard structure and are subject to technical review by experts. (a) to keep the global average temperature increase well below 2 degrees Celsius above pre-industrial levels and to continue efforts to limit the increase in temperature to 1.5 degrees Celsius above pre-industrial levels, the potential to significantly reduce the risks and effects of climate change; At the 2011 UN Climate Change Conference, the Durban Platform (and the ad hoc working group on the Durban Platform for Enhanced Action) were created to negotiate a legal instrument to mitigate climate change from 2020. The resulting agreement is expected to be adopted in 2015.  Another key difference between the Paris Agreement and the Kyoto Protocol is their scope. While the Kyoto Protocol distinguishes between Schedule 1 countries and those not annexed to Schedule 1, this branch is scrambled in the Paris Agreement, as all parties must submit emission reduction plans.  While the Paris Agreement continues to emphasize the principle of „common but differentiated responsibility and respective capabilities“ – the recognition that different nations have different capacities and duties to combat climate change – it does not offer a specific separation between developed and developing countries.  It therefore appears that negotiators will have to continue to address this issue in future rounds of negotiations, although the debate on differentiation could take on a new dynamic.  According to an analysis by the Intergovernmental Panel on Climate Change (IPCC), a carbon „budget“ based on total emissions of carbon dioxide into the atmosphere (relative to the annual emission rate) has been estimated at 1.5 to 2.25 trillion tonnes since 1870.
This represents a significant increase from the initial estimates of the Paris climate agreement (out of a total of 2000 billion tonnes) to reach the global warming target of 1.5oC, a target that would be reached in 2020 for 2017 emission rates. [Clarification needed] In addition, annual CO2 emissions are estimated at 40 billion tonnes per year in 2017.
