The climate crisis is an increasingly urgent global issue, triggering a variety of responses from countries around the world. Developed and developing countries show differences in their approaches. In Europe, the European Union is committed to reducing carbon emissions by 55% by 2030 and achieving zero emissions by 2050. This is reflected in the Green Deal policy which encourages a clean energy transition and investment in green technology. In the United States, climate policy changes significantly between administrations. In the Obama era, there were efforts to strengthen emissions regulations through the Clean Power Plan. However, this policy was canceled by the Trump administration, which prioritized the fossil industry. Currently, the Biden administration is again emphasizing the importance of climate policy, including joining the Paris Agreement and increasing investment in renewable energy. Meanwhile, countries in Asia face unique challenges. China, as the world’s largest carbon emitter, is committed to reaching peak emissions by 2030 and becoming carbon neutral by 2060. This action involves large investments in solar and wind power, although the country also continues to use coal in its energy production. On the other hand, India, as a developing country, is trying to find a balance between economic growth and environmental sustainability. India is committed to achieving 500 GW of renewable energy capacity by 2030 and is working to expand clean energy access to all its citizens. However, this country faces major challenges related to dependence on fossil energy. In the African region, various countries are facing more severe impacts of the climate crisis. Countries such as Malawi and Sudan rely on agriculture, which is highly vulnerable to climate change. Efforts to build resilience to climate change have indeed been made, but access to technology and resources remains an obstacle. Global initiatives such as COP26 in Glasgow demonstrate international efforts to address the climate crisis. There, countries discussed emission reduction targets and funding for developing countries to adapt and mitigate the impacts of climate change. The success of this meeting depends on the commitment of countries to take concrete action. Awareness of the climate crisis also encourages civil society movements with intervention from non-governmental organizations in pushing for policy change. In many countries, the climate movement educates people about the importance of sustainability and encourages them to elect leaders who care about the environment. Success in overcoming this crisis will depend heavily on international and local collaboration. The diverse approach of members of society and countries is essential for long-term strategy. Various local initiatives, such as the development of smart cities and the use of environmentally friendly public transport, show examples that change can start from the ground level. Renewable energy, energy efficiency and technological innovation are key components of the global response to the climate crisis. Thus, each country needs to carry out regular evaluations of their climate policies to ensure that the actions taken not only meet emissions targets, but also support sustainable economic growth. Synergistic efforts from all parties will determine how the world faces the challenge of the climate crisis which has long awaited a real solution.
