Yes, there are several relevant sources of secondary data on mutual funds with a focus on sustainability and climate change. Among the most reliable are Morningstar and Sustainalytics, which offer detailed ESG ratings and analyses of climate risk for funds and their portfolios. MSCI ESG Research also provides comprehensive data on funds’ exposure to climate risks and sustainable investment strategies. Refinitiv and the Bloomberg Terminal offer a wide range of financial and sustainability indicators, while the CDP (Carbon Disclosure Project) supplies data on greenhouse gas emissions and climate risk management, which are often used in fund-level analyses. Additionally, the UN PRI (Principles for Responsible Investment) publishes research reports and guidelines that support the integration of climate factors into investment decisions. These sources are valuable for academic research, market analysis, and the development of responsible investment strategies.
