However, it is important to remember that the Paris agreement is not static. Instead, it must strengthen countries` national efforts over time – meaning that current commitments are the terrain, not the ceiling, of climate change ambitions. Labor`s emissions – continuing to reduce emissions by 2030 and 2050 – have yet to be implemented and the agreement provides the instruments to ensure that this happens. 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.  Action against climate change will not only protect our planet. It will stimulate economic growth, improve the ability of countries and communities to cope with the effects and encourage innovation around the world. The Kyoto Protocol, a pioneering environmental treaty adopted at COP3 in Japan in 1997, is the first time nations have agreed on country-by-country emission reduction targets.
The protocol, which only came into force in 2005, set binding emission reduction targets only for industrialized countries, based on the fact that they are responsible for most of the world`s high greenhouse gas emissions. The United States first signed the agreement, but never ratified it; President George W. Bush argued that the agreement would hurt the U.S. economy because developing countries such as China and India would not be included. In the absence of the participation of these three countries, the effectiveness of the treaty was limited, as its objectives covered only a small fraction of total global emissions. InDCs become CNDs – nationally determined contributions – as soon as a country formally adheres to the agreement. There are no specific requirements as to how or how many countries should reduce emissions, but there were political expectations about the nature and rigour of the targets set by different countries. As a result, the scale and ambition of national plans vary widely, largely reflecting each country`s capacity, level of development and contribution to emissions over time.
China, for example, has committed to cleaning up its CO2 emissions by 2030 at the latest and reducing CO2 emissions per unit of gross domestic product (GDP) by 60-65% by 2030 from 2005 levels.
