The paper examines how global climate agreements, regional initiatives, and grassroots activism influence policy frameworks in developing nations. It explores the friction between top-down international mandates (such as the Paris Agreement) and the socio-economic realities of the Global South, where climate policies frequently contend with development imperatives and localized vulnerabilities. The study assesses how activism and advocacy attempt to shape national climate strategies, promote localized climate justice, and drive policy shifts in developing regions.
