The UN has hosted climate summits known as COPs since 1995 to address greenhouse gas emissions and climate change. Notable events include the establishment of UNFCCC in 1992, the Kyoto Protocol in 1997, the Paris Agreement in 2015, and COP28’s recent commitment to transitioning away from fossil fuels by 2050. The journey has been marked by significant agreements and persistent challenges, reflecting the complexity of international climate negotiations.
Since 1995, the United Nations has convened global climate summits, recognized as COPs (Conference of the Parties), aimed at mitigating greenhouse gas emissions and averting climate change. Significant milestones in these negotiations include the establishment of the UN Framework Convention on Climate Change (UNFCCC) at the Earth Summit in Rio de Janeiro in 1992, establishing a foundation for future climate action. The first COP, held in Berlin in 1995, was characterized by distinct priorities surrounding climate change. By 1997, the Kyoto Protocol emerged, mandating industrialized nations to reduce greenhouse gas emissions by an average of 5.2 percent from 1990 levels between 2008 and 2012. However, following the refusal of the United States to ratify the protocol, which came into force in 2005, emissions continued to rise unabated. COP15 in Copenhagen in December 2009 failed to produce a coherent agreement for post-2012 commitments amidst ongoing disputes between developed and developing nations concerning equitable responsibilities for carbon emissions. Nevertheless, major emitters including China and the United States committed to capping global temperature increases at 2 degrees Celsius, although implementation strategies remained unclear. The 2015 Paris Agreement saw about 195 countries commit to limiting global warming to “well below” 2 degrees Celsius, with aspirations for a more ambitious target of 1.5 degrees Celsius. However, a global stocktake in 2023 revealed that current trajectories do not align with these targets, necessitating urgent and bold governmental actions. At COP26 in Glasgow in 2021, nearly 200 nations united under the leadership of Britain’s Alok Sharma to expedite measures against climate change, but the final agreement faced dilution due to the influence of India and China, who sought to preserve high levels of coal usage. In 2023, COP28 in Dubai resulted in a groundbreaking agreement for a global transition away from fossil fuels, with a unified objective of achieving net-zero emissions by 2050. This marked the first occasion that all fossil fuels were mentioned explicitly in a COP agreement, although skepticism remained due to the absence of precise deadlines and the potential for loopholes favoring fossil fuel producers.
The UN climate summits, initiated in the wake of globally recognized climate challenges, have evolved in scale and scope since their inception in the 1990s. The urgency of climate action has been underscored by an increasing awareness of the detrimental impacts of greenhouse gas emissions, necessitating a collective global response facilitated by coordinated agreements. The delicate balancing act between developed and developing nations regarding emission reduction commitments and responsibilities has been a recurring theme throughout these negotiations, influencing the outcomes of various COPs over the decades. Each summit contributes to the larger dialogue on climate action, reinforcing international cooperation and accountability in combating climate change.
The history of the COPs illustrates a persistent effort to unite the global community in confronting the rising threat of climate change through collaborative commitments and agreements. Despite some successes, such as the Paris Agreement and the recent declaration at COP28, significant challenges remain, particularly regarding the ambitious goal of limiting temperature rise to 1.5 degrees Celsius. The evolution of these negotiations highlights the importance of continual dialogue, adaptation of strategies, and unwavering commitment from all nations to fulfill their responsibilities towards achieving a sustainable future.
