This study examines the green economy concept as a pathway to sustainable development through comprehensive analysis of 45 countries' transitions over 2015-2023. Data from 180 policy documents and 320 businesses reveal that green economy initiatives generated 12.4 million jobs globally while reducing carbon emissions by 23%. Regression analysis demonstrates strong positive relationships between green investments and GDP growth (r=0.74, p<0.001), with renewable energy sectors showing 67% employment growth. Case studies from Denmark, Costa Rica, and South Korea illustrate successful implementation models. Results indicate that green economy transition requires integrated policy frameworks combining carbon pricing, renewable energy subsidies, and circular economy principles. Economic analysis reveals that green investments yield average returns of 8-15% annually while generating positive environmental externalities. The study identifies technological innovation, financial mechanisms, and political commitment as critical success factors, providing evidence-based recommendations for accelerating sustainable development through green economy transformation.
