Climate change has emerged as one of the most significant global challenges of the twenty-first century, affecting ecosystems, economies, human health, and societies in profound ways. While international agreements and national policies play a major role in tackling climate change, the role of state governments is equally critical, especially in a federal structure like India. Climate change impacts are highly localized, and therefore, effective adaptation and mitigation measures often need to be designed and implemented at the sub-national level. State governments are uniquely positioned to integrate climate concerns into development planning, ensure coordination across sectors, and respond to the specific vulnerabilities of their regions. Their role becomes even more vital because they act as the interface between local communities and national policies, thereby bridging the gap between global frameworks and grassroots realities. One of the most important roles of state governments in addressing climate change is policy formulation and planning. Many states in India have prepared State Action Plans on Climate Change (SAPCCs) in line with the National Action Plan on Climate Change (NAPCC). These action plans outline strategies and sectoral priorities tailored to the specific geographical, social, and economic contexts of the state. For example, a coastal state like Odisha emphasizes disaster management and coastal zone protection, while a Himalayan state like Himachal Pradesh focuses more on glacier retreat, forest conservation, and sustainable tourism. Through these plans, states are able to articulate their climate priorities, identify vulnerable sectors, and design region-specific responses. State governments also play a central role in the implementation of climate policies. While national frameworks may outline broad strategies, the actual execution of renewable energy projects, afforestation drives, energy efficiency programs, or disaster preparedness measures often falls within the jurisdiction of the states. For instance, states manage electricity distribution companies, which are central to promoting renewable energy integration into the grid. Similarly, agriculture, water resources, and local transport systems are largely under state purview, making state-level interventions crucial for sustainable practices. Thus, the ability of state governments to translate policy into action determines the effectiveness of climate responses on the ground. Another significant responsibility of state governments lies in the area of capacity building and institutional development. Addressing climate change requires not only financial resources but also technical knowledge, skilled manpower, and robust institutions. State governments establish specialized climate cells or nodal agencies to coordinate climate-related initiatives. These agencies facilitate research, collect data on emissions and vulnerabilities, and provide scientific inputs for policy design. States also collaborate with academic institutions, NGOs, and international organizations to strengthen local capacity for climate adaptation. By enhancing institutional mechanisms, states ensure that climate action is not just a one-time activity but an ongoing process embedded into governance structures. State governments are also responsible for integrating climate change concerns into developmental
