Established by Dr. Ma Jun, the Institute of Finance and Sustainability (IFS) is a Beijing-based non-profit think tank specialized in ESG investment, natural capital, green technology innovation, and low-carbon transitions. Its mission is to advance green finance and sustainable development in China and globally, through high-quality research, capacity building, and advocacy work on green finance policies as well as market and product development. IFS clients include international organizations, domestic and foreign governments, financial institutions, and enterprises. In recent years, the IFS has established and served as the secretariat for global initiatives, including but not limited to : 1) The Green Investment Principles (GIP) for the Belt and Road, launched in November 2018 by the China Green Finance Committee and the City of London Corporation with international partners, aim to scale sustainable finance in the global south. This initiative gathers key financial institutions to foster sustainable finance, especially in EMDEs, offering a platform for knowledge exchange and capacity enhancement. In five years, the GIP has evolved into a consortium of over 60 global entities across various economies. 2) The Capacity-Building Alliance of Sustainable Investment (CASI) is an international platform launched at COP28 in 2024, dedicated to providing impactful sustainable finance training services for EMDEs. CASI aims to train 100,000 individuals by 2030 and will initiate its offerings in 2024 with four learning programs: in-person events, monthly seminars/webinars, e-learning products featuring a certificate program, and customized capacity-building events.
