The climate crisis has become an urgent global issue, facilitating policy changes in many countries. In recent years, extreme weather phenomena, such as floods, droughts and storms, have called for greater attention to the need for policies that are more responsive to climate change. Countries around the world are starting to adopt stricter measures to reduce greenhouse gas emissions and serve as a driver in the transition to renewable energy. One concrete example of policy change is the 2015 Paris agreement, in which almost all world countries committed to keeping global temperatures below 2 degrees Celsius above pre-industrial levels. Many countries are starting to implement national action plans that include the development of alternative energy and energy efficiency. In the European Union, for example, the European Green Deal aims to make the continent carbon neutral by 2050, with a focus on green investment and reducing industrial emissions. In the US, the Biden administration has revived the country’s climate commitments and is pushing green policies, including initiatives to reduce dependence on fossil fuels. These steps are expected to help create millions of jobs in the clean energy and technological innovation sectors. These policy changes are not only occurring in developed countries; many developing countries are also adapting policies to increase climate resilience. Environmentally friendly policies are also starting to be integrated in various sectors, such as transportation, agriculture and industry. The world’s major cities are pioneering sustainable transportation initiatives, including developing infrastructure for electric vehicles. Even in the agricultural sector, sustainable farming techniques and agroecology are being introduced to minimize environmental impacts and maintain food security. Public support and public awareness of the importance of climate change issues also encourage this policy change. A growing social movement, led by young activists, has succeeded in pressuring the government to take concrete steps to address the climate crisis. World leaders now face greater demands to commit to sustainable and just policies. With increasing investment in green technology and renewable energy, we can see a global economic transformation. Innovations such as energy storage, solar panels and ocean breezes are becoming more common, changing the way energy is produced and consumed. Awareness of the negative impacts of fossil fuels has encouraged many companies to adopt more comprehensive sustainability policies. Overall, the climate crisis is not only changing policies at the local level but also in the global context. International agreements and collaboration between countries are very important to ensure the effectiveness of implemented policies. By involving all stakeholders, from governments to the private sector and civil society, the necessary changes can be made to face today’s urgent climate challenges.
