Central banks' green monetary policies are crucial for promoting sustainable development and mitigating climate change. Establishing a stable green monetary policy transmission mechanism will create incentives for financial institutions to engage in green activities, ensuring transparency in reporting and monitoring green investment. This article focuses on analyzing the transmission mechanisms of green monetary policy through instruments such as preferential interest rates and the issuance of green bonds, thereby creating favorable conditions for the development of renewable energy projects and clean technologies. The research is based on data from 2020 to 2023 and the experiences of the United Kingdom and Germany, two pioneering countries in the field of green finance. The findings provide assessments of the successes, limitations, and underlying reasons for the implementation of green monetary policy in these two nations. Based on the research results, the article presents recommendations for Vietnam on the application of green monetary policy within its financial system, contributing to environmental protection, minimizing the impact of climate change, and fostering sustainable development in Vietnam.
