Climate change is one of the greatest challenges facing humanity today. Rising global temperatures, changes in rainfall patterns, and the increasing frequency of natural disasters are issues that require global attention. Global policies in dealing with these changes are very important because the broad impacts know no national borders. International policies such as the 2015 Paris Agreement demonstrate the world’s commitment to limiting global temperature rise to below 2 degrees Celsius. However, implementation remains a serious challenge. Many countries have not yet achieved their emissions reduction targets, and political uncertainty often hinders progress. In this context, transparency and accountability become essential. Climate change has a major impact on the agricultural sector, which is a source of livelihood for the majority of the population in developing countries. Adaptation policies are needed to help farmers shift to more sustainable agricultural practices, such as organic farming and agroforestry. The use of technology such as precision irrigation can help overcome the problem of drought which is occurring more frequently due to climate change. The industrial sector must also adapt. Policies that encourage innovation and the application of renewable energy are important steps. Incentives for companies to invest in green technology could increase international trade. Additionally, reducing industrial waste through recycling and effective waste management is an important step in reducing the carbon footprint. At the community level, awareness and education about climate change must be increased. Programs that educate the public about environmentally friendly practices can have a positive impact. Strengthening the role of non-governmental organizations in climate change policy advocacy can also encourage public participation in formulating better policies. Funding is also an important pillar in global policy. Modernization of the energy sector and more resilient infrastructure requires large investments from the government, private sector and international institutions. Innovative financing mechanisms, such as green bonds, can attract investment into sustainable projects. Stronger international cooperation is needed to address these cross-border challenges. Strengthening multilateral forums such as the COP (Conference of the Parties) can create a platform for countries to discuss and share solutions. Technology exchange between developing and developed countries should also be facilitated to accelerate the transition to a sustainable economy. Science-based policies are crucial in decision making. Research on the impacts of climate change should be encouraged to produce better data. This is important in formulating targeted solutions and minimizing risks. Addressing climate change is not just about reducing emissions; This is about socio-economic transformation. The transition to a green economy requires the involvement of all sectors. The involvement of local communities in policy planning and implementation is essential to ensure sustainability. Ultimately, food security, clean water, and health must be a primary focus when considering climate change. Holistic and integrated policy implementation can shape a better, sustainable and fair future for all.
