The role of State governments in addressing climate change is crucial because they operate at the interface between national policies and local implementation. While international agreements and national frameworks provide broad mandates, it is the State-level authorities that translate these directives into practical actions affecting communities, ecosystems, and economies. States possess a deeper understanding of regional vulnerabilities, resource availability, and socio-economic contexts, enabling them to design targeted strategies that respond to specific climate challenges. Their role extends across planning, regulation, capacity building, adaptation initiatives, and coordination with multiple stakeholders, making them the backbone of climate governance in federal systems. One of the major responsibilities of State governments is policy formulation tailored to regional needs. States prepare climate action plans outlining sector-specific strategies for mitigation and adaptation. These plans often focus on areas like agriculture, energy, transport, water resources, forests, and urban development, which are highly climate-sensitive. By conducting vulnerability assessments and risk mapping, states identify regions most threatened by climate impacts such as droughts, floods, sea-level rise, or extreme heat events. Based on these assessments, they develop policies that promote climate-resilient practices, reduce greenhouse gas emissions, and improve disaster preparedness. Furthermore, State governments integrate climate considerations into broader development plans, ensuring that economic growth does not compromise environmental sustainability. Another central role of State governments lies in regulating key sectors that significantly contribute to emissions or are vulnerable to climate change. States oversee land-use planning, industrial approvals, transportation policies, and building regulations, which are crucial for mitigation efforts. For example, they can
