This study explores the current status, challenges, and countermeasures of green renovation in old residential communities in Changchun City, focusing on the specific practices and major problems the city faces in its green development pathways. The paper showcases Changchun City’s achievements in green renovation in areas such as building energy efficiency, resource recycling, and smart community construction through an analysis of policy backgrounds and case studies. However, challenges such as insufficient funding, limited technical support, low resident participation, and weak enforcement of regulations and policies remain significant barriers to green renovation progress. Therefore, this paper proposes countermeasures such as innovative financing models, enhanced technical support, increased resident participation, improved legal frameworks, and the promotion of intelligent management systems to advance sustainable green development in the renovation of old residential communities in Changchun City. Looking forward, as technology advances and policies are optimized, the green renovation in Changchun City will gradually deepen, achieving more efficient and sustainable development goals.
