In a joint letter, European Council President Donald Tusk and European Commission President Jean-Claude Juncker reaffirmed their commitment to implementing the Paris Agreement and stressed the EU`s commitment to the 2030 targets ahead of the SEPTEMBEr 2019 UN climate change summit and the UN Climate Change Conference (COP25) in December 2019. These rules of transparency and accountability are similar to those set out in other international agreements. Although the system does not include financial sanctions, the requirements are intended to easily monitor the progress of individual nations and promote a sense of overall group pressure, discouraging any towing of feet among countries that might consider it. The Paris Agreement was launched at the signing on April 22, 2016 (Earth Day) at a ceremony in New York.  After the agreement was ratified by several EU member states in October 2016, there were enough countries that had ratified the agreement to produce enough greenhouse gases in the world for the agreement to enter into force.  The agreement came into force on November 4, 2016.  The EU is committed to the Paris Agreement and intends to play a leading role in the fight against 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.  The EU is committed to implementing the Paris Agreement on climate change. According to the United Nations Environment Programme (UNEP), temperatures are expected to rise by 3.2oC by the end of the 21st century, based solely on the current climate commitments of the Paris Agreement. To limit the increase in global temperature to 1.5 degrees Celsius, annual emissions must be below 25 Gigaton (Gt) by 2030.
With the current commitments of November 2019, emissions by 2030 will be 56 Gt CO2e, twice the environmental target. To limit the increase in global temperature to 1.5 degrees Celsius, an annual reduction in emissions of 7.6% is needed between 2020 and 2030. The four main emitters (China, the United States, the EU-27 and India) have contributed more than 55% of total emissions over the past decade, excluding emissions due to land use changes such as deforestation. China`s emissions increased by 1.6% in 2018 to a peak of 13.7 Gt CO2 equivalent. U.S. emissions account for 13% of global emissions and emissions have increased by 2.5% in 2018. EU emissions, which account for 8.5% of global emissions, have fallen by 1% per year over the past decade. Emissions fell by 1.3% in 2018. In 2018, 7% of India`s global emissions increased by 5.5%, but its per capita emissions are one of the lowest in the G20.  In December 2019, EU leaders approved the goal of making the EU climate neutral by 2050. Poland has not been able to commit to this goal at this stage and the European Council will return to this issue in June 2020. EU heads of state and government have recognised the need to ensure a cost-effective, socially equitable and equitable transition, taking into account different national situations.
The level of the NDC set by each country will determine the objectives of that country. However, the “contributions” themselves are not binding under international law because of the lack of specificity, normative nature or language necessary to establish binding standards.  In addition, there will be no mechanism to compel a country to set a target in its NDC on a specified date and not for an application if a defined target is not achieved in an NDC.   There will be only one “Name and Shame” system or as “I`m Our Pesztor,” the United States.
