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. Under the UNITED Nations Framework Convention on Climate Change, legal instruments can be adopted to achieve the convention`s objectives. For the period 2008-2012, measures to reduce greenhouse gas emissions were agreed in the 1997 Kyoto Protocol. The scope of the protocol has been extended until 2020 with the Doha amendment to the protocol.
 Countries are also working to reach „the global peak in greenhouse gas emissions“ as soon as possible. The agreement has been described as an incentive and engine for the sale of fossil fuels.   Recognizing that many developing countries and small island developing states that have contributed the least to climate change are most likely to suffer the consequences, the Paris Agreement contains a plan for developed countries – and others that are able to do so – to continue to provide financial resources to help developing countries reduce and increase their resistance to climate change. The agreement builds on the financial commitments of the 2009 Copenhagen Accord, which aimed to increase public and private climate finance to developing countries to $100 billion per year by 2020. (To put it in perspective, in 2017 alone, global military spending amounted to about $1.7 trillion, more than a third of which came from the United States. The Copenhagen Pact also created the Green Climate Fund to mobilize transformation funding with targeted public dollars. The Paris agreement expected the world to set a higher annual target by 2025 to build on the $100 billion target by 2020 and create mechanisms to achieve this.
