A Historical Overview of UN Climate Summits: The COPs

The UN has organized COPs since 1995 to address climate change and stabilize emissions. Key moments include the Kyoto Protocol in 1997, the Paris Agreement in 2015, and the recent COP28 in 2023, which called for a transition away from fossil fuels. Despite progress, challenges remain as the world struggles to meet climate goals.

Since 1995, the United Nations has conducted global climate summits known as COPs (Conference of the Parties) in an effort to stabilize greenhouse gas emissions and combat climate change. Noteworthy gatherings include the establishment of the UNFCCC during the 1992 Earth Summit in Rio de Janeiro, following alarming reports in 1990 about rising greenhouse gases due to human activities. The inaugural COP in Berlin, 1995, marked the beginning of diverse priorities in addressing climate issues. In 1997, the Kyoto Protocol represented a significant agreement to reduce emissions by an average of 5.2% for industrialized nations from 1990 levels within 2008-2012. However, the United States declined to ratify this protocol, leading to its ineffective implementation post-2005. The turn of events at COP15 in Copenhagen in 2009 further demonstrated the complexities of arriving at consensus, as rich and poor nations struggled to agree on pertinent post-2012 strategies, despite some progress in establishing a political goal for temperature increases. By 2015, the Paris Agreement was signed by around 195 countries, aiming to limit warming to “well below” 2 degrees Celsius above pre-industrial levels, with a more ambitious 1.5 degrees Celsius target also adopted. Nonetheless, a global stocktake in 2023 revealed insufficient advancement towards the 1.5 degrees Celsius goal, necessitating urgent actions from governments and stakeholders. At COP26 in Glasgow in 2021, nearly 200 nations made commitments to accelerate efforts against climate change, although the final agreement was softened by influential nations. The latest COP28 in Dubai in 2023 heralded a groundbreaking accord that recognized the need to transition away from fossil fuels to achieve net-zero emissions by 2050, marking the first instance of explicit fossil fuel mention in a COP agreement. While there was celebrated approval of the agreement, concerns remained among smaller nations regarding the vagueness of the timeline and the potential loopholes for hydrocarbon-producing countries.

The COP summits symbolize global efforts to address climate change, initiated by the UN in response to the growing recognition of human-induced environmental impacts. The evolution of COPs reflects the complexities and challenges inherent in international negotiations, particularly concerning the interests of developed versus developing nations, and the continuing rise of global emissions despite established agreements. These summits serve as platforms for nations to review commitments, set new targets, and engage in vital negotiations for effective climate action, with increasing urgency as climate impacts become more pronounced.

In summary, the series of COP summits illustrates an ongoing struggle to reach effective agreements on climate change, revealing the challenges of balancing diverse national interests and the pressing nature of environmental science. The landmark decision from COP28 on transitioning away from fossil fuels is a significant step, but it also highlights the need for more definitive action and commitments from all nations to truly address the climate crisis.
