– 1997 in Kyoto (COP 3), which adopted the Kyoto Protocol, an agreement between a number of Annex I countries, including all EU Member States of the time (Kyoto Protocol), which included, among other things, the agreed emission reduction for each of the Annex I countries for the period up to 2012; in 2007 in Bali (COP 13), which adopted the Bali Action Plan, which laid the groundwork for agreements on climate change, adaptation, technological cooperation and financial support. The plan recognizes the need for drastic reductions for Schedule I countries, with detailed references to the AR4, including a table indicating that Schedule I countries must achieve a 25-40% reduction in emissions by 2020 compared to 1990 to remain below the warming target of 2oC; 2009 in Copenhagen (COP 15) where no agreement could be reached on the monitoring or continuation of the Kyoto Protocol in 2010 in Cancun (COP 16), which included recognition based on scientific knowledge in IPCC reports, including, among other things, a reference in the preamble to the urgency of a drastic reduction in emissions – the long-term goal for global warming of up to 2oC, with a possible strengthening of the target to 1.5oC. The CDP also stated that Schedule I countries should remain at the forefront of the fight against climate change and that this requires Schedule I countries to reduce their greenhouse gas emissions by 25-40% by 2020 compared to 1990. The COP also called on Annex I countries to strengthen their ambitions, individually or collectively, in relation to the previous commitments of The Annex I countries (the so-called Cancun commitments). For the EU, Cancun`s commitments represented a 20% reduction by 2020 compared to 1990, with the offer to achieve a 30% reduction target if other developed countries commit, among other things, to achieving similar reduction targets. In 2011 in Durban (COP 17), with a joint statement on the essential difference between the mitigation plans of the participating countries and the “probable” scenarios (> 66%) The opportunity, the target of 2OC/1.5oC and an agreement for the conclusion of a new one, to achieve, by 2015, the 25-40% reduction targets for Schedule I countries by 2020, up from 25-40% in 2012 in Doha (COP 18), when it was asked to increase its reduction targets to at least 25-40% by 2020. During this COP, the Doha amendment was adopted in line with the Kyoto Protocol with commitments to reduce emissions until 2020. The EU has again pledged to reduce by 20% by 2020, with the offer of a 30% reduction target by 2020, provided that, in short, other developed countries do the same. This condition has not been met and the Doha amendment has not (yet) entered into force; in 2013: in Warsaw (COP 19), with the request for an increase in the target by 2020 and the Annex I countries to comply with the target of a reduction of 25-40% by 2020, reaffirmed in Doha; In 2015: in Paris (COP 21) (the Paris Climate Conference) which resulted in the Paris Agreement (see also the legal basis 15). calling for more ambition and enhanced cooperation to bridge the gap between the current emissions targets and the Paris Agreement targets, as well as new measures to combat climate change well before 2020; in 2017 in Bonn (COP 23), where the need for “enhanced measures” was recognised for the period up to 2020.
