While the enhanced transparency framework is universal and the global inventory is carried out every five years, the framework must provide “integrated flexibility” to distinguish the capabilities of developed and developing countries. In this context, the Paris Agreement contains provisions to improve the capacity-building framework.  The agreement recognizes the different circumstances of some countries and notes, in particular, that the technical review of experts for each country takes into account the specific capacity of that country to report.  The agreement also develops a capacity-building initiative for transparency to help developing countries put in place the necessary institutions and procedures to comply with the transparency framework.  One of the main outcomes of the 2015 Paris Agreement was that the United States and China originally signed, although the United States has since descended. Together, the United States and China account for about 43% of global emissions: 28% to China and 15% to the United States. All signatories agreed to the goal of reducing greenhouse gas emissions due to rising temperatures and other risks that affect the world. Another important element of the agreement is that it includes countries that depend on oil and gas extraction revenues. Around the world, 600,000 people took part in demonstrations in support of a strong agreement, such as the Global Climate March organized by 350.org (and other events such as Alternatiba, Village of Alternatives). Paris has been banned from public gatherings in the wake of the recent terrorist attacks (state of emergency), but allowed thousands of people to demonstrate on 12 December against what they consider too weak a treaty.
 An illegal demonstration was also held in Paris, during which violent clashes broke out between police and anarchists, 10 police officers were injured and 317 people arrested.   Carbon dioxide, nitrous oxide and methane are gases that accumulate in the atmosphere and prevent radiation from the Earth`s surface to space, creating what is called the greenhouse effect. According to the Intergovernmental Panel on Climate Change (IPCC), the main international panel on this issue, the concentration of these thermal gases has increased significantly since pre-industrial times and has not been observed for at least 800,000 years.
