Climate change is one of the greatest challenges facing the world today, affecting ecosystems, societies and economies across the planet. Global diplomacy plays a crucial role in overcoming this problem through international cooperation. Countries around the world must unite to face the impacts of climate change, which include rising temperatures, rising sea levels and extreme weather. The Climate Change Conference held annually, such as the Conference of the Parties (COP) under the framework of the United Nations Convention on Climate Change (UNFCCC), is an important event for formulating global agreements. The 2015 Paris Agreement, signed by almost all the world’s countries, set a target of holding global temperature rise to below 2°C compared to pre-industrial levels. In order to achieve this target, countries are committed to reducing greenhouse gas emissions and increasing the use of renewable energy. At the global level, collaboration is very necessary. Developed countries have more responsibility in helping developing countries which are often most affected by the impacts of climate change even though they have lower emission contributions. Financial assistance and technology transfer are vital to support mitigation and adaptation efforts in vulnerable countries. Through international forums, such as the G20 and G7, world leaders can engage in dialogue and negotiate collective commitments to address these issues. The role of the private sector is also very important in climate change diplomacy. Companies are now increasingly aware of the importance of sustainability. Through investment in green technologies and environmentally friendly policies, the private sector can accelerate the transition to a more sustainable economy. By facilitating collaboration between government and industry, innovation focused on climate change can be accelerated. In addition, non-governmental organizations (NGOs) and civil society groups also provide critical support in diplomatic efforts. They often maintain transparency, responsible governance, and community involvement. Through awareness campaigns, they urge the government to act more decisively on climate change. Climate change is not only an environmental issue, but also affects security, health and human rights. The spread of disease, population displacement due to natural disasters, and resource conflicts are becoming increasingly pressing issues. Therefore, global diplomacy must involve a cross-sectoral approach that links these issues. The renewable energy revolution is an integral part of the solution to overcome climate change. Investments in renewable energy such as solar, wind and biomass have the potential to reduce dependence on fossil fuels. Technological advances in energy storage and energy efficiency are driving this transition. In solving climate change problems, community participation becomes very relevant. Education about the importance of sustainability and reducing carbon footprints can encourage individuals to contribute to positive change. Collective action from the individual to the global level is needed to face this challenge. Strengthening bilateral and multilateral relations between countries is also an important strategy in climate change diplomacy. Through ongoing dialogue, countries can share best practices, identify opportunities for cooperation, and collectively set ambitious targets. Ultimately, without immediate action and global collaboration, the impacts of climate change will worsen. Facing these challenges requires strong commitment from all parties, as well as innovation, adaptation and the courage to make fundamental changes in the way we operate in the global social and economic context. Building mutually beneficial partnerships and prioritizing sustainability is the key to a better future.
