As host and president of COP21, France is committed to supporting a multilateral negotiation process and listening to all parties involved to reach an agreement: to compare the Bland Altman measurement systems, the differences between the different measures are calculated, and then the average value and the standard deviation are deducted. The 95% of “agreement limits” are calculated as the average of the two values minus and plus 1.96 standard deviation. This 95 per cent agreement limit should include the difference between the two measurement systems for 95 per cent of future measurement pairs. The 197 “negotiators” committed to developing long-term strategies to develop low-greenhouse gas emissions. This is the first time that a universal agreement has been reached in the fight against climate change. Bland-Altman parcels were also used to investigate a possible link between the differences between the measurements and the actual value (i.e. proportional distortion). The existence of proportional distortion indicates that the methods do not uniformly correspond to the range of measures (i.e., the limits of compliance depend on the actual measure). To formally assess this relationship, the difference between methods should be reduced to the average of the two methods.
If a relationship between differences and actual value has been identified (i.e. a significant slope of the regression line), 95% regression-based agreements should be indicated.  Myles – Cui.

In response to the climate challenge, the agreement recognizes that states have common but differentiated responsibilities, i.e. according to their national capabilities and specificities. COP 21 or the Paris Climate Conference have resulted in a new international climate agreement that applies to all countries and aims to keep global warming below 2 degrees Celsius, in line with the recommendations of the Intergovernmental Panel on Climate Change (IPCC). A Bland-Altman plot (differential diagram) in analytical chemistry or biomedicine is a method of data representation used in the analysis of the agreement between two different trials.
It is identical to a tube of average difference Tukey, the name under which it is known in other areas, but it was popularized in the medical statistics of J. Martin Bland and Douglas G. Altman.   States parties are subject to certain legally binding provisions, such as the requirement for developed countries to provide financial assistance to developing countries to enable them to implement the agreement. The agreement officially entered into force on 4 November 2016, a few days before COP22, and was ratified by 169 countries (including the European Union 28), which account for 87.75% of emissions.
