UN Secretary-General Ban Ki Moon called on world leaders to agree on an agreement to curb global warming at the 69th session of the UN General Assembly on 23 September 2014 in New York. The next climate summit was held in Paris in 2015, the date of the Paris Agreement, which succeeded the Kyoto Protocol. For the purposes of determining entry into force, Article 21 of the Paris Agreement provides for the UNFCCC secretariat to publish a list of the most up-to-date emissions data provided by the contracting parties. For many parties, the percentage of programming in this table does not reflect their current programming. This is because developing countries have recently been required to report their national emissions on a regular basis. This will change under the Paris Agreement, as all countries are required to submit a regular national emissions inventory report. Critics and supporters of the measure noted that much more needs to be done before the agreement comes into force. There is a need to develop mechanisms for monitoring and reporting current emissions and selection criteria for conservation programs and other projects charged to offsets. The Kyoto Protocol is an international treaty that extends the 1992 United Nations Framework Convention on Climate Change (UNFCCC), which requires States Parties to reduce greenhouse gas emissions, based on the scientific consensus that global warming is taking place (part 1) and (part two) it is very likely that human-caused CO2 emissions are the majority cause. The Kyoto Protocol was adopted on 11 December 1997 in Kyoto, Japan, and came into force on 16 February 2005.
There are currently 192 parties (Canada withdrew from the protocol as of December 2012). The agreement adds an exclamation point for a week in which enough countries have signed the broader Paris climate agreement to ensure it enters into force this year. Heads of state and government welcomed the agreement, which will come into force in 2021, which is an important step in reducing the impact of international aviation on the environment, which currently accounts for about 2% of global greenhouse gas emissions. Under the protocol, only Schedule I parties have committed to achieving national or common reduction targets (officially known as quantified emissionslimit and objective reductions (QELRO) – Article 4.1).  Parties to the Kyoto Protocol that are not included in Schedule I of the Convention (the non-contracting parties in Schedule I) are, for the most part, low-income developing countries:4 and can participate in the Kyoto Protocol through the Clean Development Mechanism (hereafter).  All these years of negotiations culminated in the draft Kyoto Protocol in 1997. The pact required a reduction of about 5% in global emissions from 1990-2012 levels, and an emissions reduction target has been assigned to each developed country.
