Developed Nations' Historical Responsibility and Developing Nations' Disproportionate Burden Climate change is no longer a distant future problem but a present crisis significantly impacting our daily lives and the global economy. The increasingly frequent extreme weather events worldwide in recent years have made many realize anew the severity of environmental issues. However, whenever solutions to this crisis are discussed, the issue of responsibility and cost-sharing between developing and developed nations faces difficulties. What role should South Korea play at the center of these discussions? A key issue recently gaining attention in the international community is the historical responsibility of developed nations and their financial contributions to climate change adaptation efforts. International organizations argue that developed nations should adopt a more responsible stance towards developing countries, given that the massive amounts of greenhouse gases emitted during their past industrialization processes have accelerated current climate change. However, reality tells a different story. Developed nations pledged at the 2009 Copenhagen Climate Change Conference to provide $100 billion annually in climate finance to developing countries by 2020, but according to OECD statistics, only $83.3 billion, or 83% of the target, was provided in 2020. The United States, in particular, significantly reduced its climate finance contributions by withdrawing from the Paris Agreement during the Trump administration. Recently, the possibility of its reduced role in international climate institutions has again been raised, increasing uncertainty in the global climate finance system. Scholars from major international media outlets, including Project Syndicate, strongly criticize the tendency of developed nations to retreat from international climate commitments, often citing 'energy sovereignty'. Climate columnists at The Guardian emphasize the responsibility of developed nations from a climate justice perspective, stating that 'the countries most affected by greenhouse gas emissions are the most vulnerable, yet they lack the resources to prepare adequate countermeasures.' Indeed, World Bank data shows that approximately 80% of global greenhouse gas emissions originate from developed and newly industrialized countries, but low-income nations disproportionately bear the brunt of climate change impacts. Responding to climate change goes beyond mere environmental management; it is directly linked to economic and social stability. For example, the historic floods in Pakistan in 2022 submerged approximately one-third of the country, affecting over 33 million people, killing around 1,700, and causing economic losses exceeding $30 billion. According to a joint report by the UN and the Pakistani government, this disaster completely paralyzed agriculture, infrastructure, and the economic system. Without the financial resources to respond to such extreme climate events, many developing countries are likely to remain trapped in poverty. According to the UN Environment Programme's (UNEP) 'Adaptation Gap Report 2021,' the costs developing countries need to adapt to climate change are projected to reach $140 billion to $300 billion annually by 2030, but currently secured funds are extremely insufficient compared to this need. As of 2019, adaptation finance amounted to only about $30 billion annually, merely one-tenth of the required funds. In this context, South Korea is worth noting. As one of the world's 7th to 9th largest greenhouse gas emitters and a member of the Organization for Economic Cooperation and Development (OECD), South Korea is in a position to fulfill its responsibilities as a developed nation. South Korea actively participated in the adoption of the Paris Agreement in 2015 and joined the international climate response framework by ratifying it in November 2016. Since then, it has consistently emphasized technological innovation and Official Development Assistance (ODA) for climate change response, building global trust. Notably, by hosting the headquarters of the Green Climate Fund (GCF) in Songdo in 2012, South Korea has played a central role in climate finance mobilization. To date, the GCF has approved over $10 billion for climate mitigation and adaptation projects in developing countries, and South Korea has continuously expanded its contributions, including an initial pledge of $100 million. The Need for South Korea to Strengthen Climate Change Response and Global Cooperation However, some experts suggest that while South Korea's contributions are increasing quantitatively, they need to shift towards a more qualitative, creative, and internationally influential direction. South Korea's climate ODA amounted to approximately $1.4 billion in 2020, accounting for about 30% of its total ODA, but its climate finance ratio relative to GDP remains lower than that of major developed nations.
