Although the Paris Agreement has entered into force, its implementation has yet to be clarified by numerous enforcement decisions. These are marked by the publication by each party of their long-term climate strategy. The implementation of the climate plan in July 2017 by Nicolas Hulot, then Minister of Ecological and Inclusive Transition, ensured the implementation of the Paris Agreement at the national level. By 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 to limit global warming to 1.5 degrees Celsius and 2.25 trillion tonnes from the 1870 period. 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. The revised IPCC budget was based on the CMIP5 climate model. Estimate models using different reference years also provide other slightly adjusted estimates of a carbon “budget.”  The Paris Agreement officially entered into force on 4 November 2016. Other countries remained parties to the agreement following their national approval procedures. To date, 195 contracting parties have signed the agreement and have ratified 189.

The Paris Agreement is an agreement within the framework of the United Nations Framework Convention on Climate Change (UNFCCC) that deals with the reduction, adaptation and financing of greenhouse gas emissions from 2020. The agreement aims to address the threat of global climate change by keeping global temperatures well below 2 degrees Celsius above pre-industrial levels this century and to continue efforts to further limit the temperature increase to 1.5 degrees Celsius.  These rules of transparency and accountability are similar to those set out in other international agreements.
