Green Century MSCI International Index Fund Institutional 

This fund endeavors to achieve substantial long-term growth by replicating the performance of its benchmark, the MSCI World ex USA SRI ex Fossil Fuels Index. It primarily invests in the common stocks that make up this specific index. The underlying index is a specialized version of the MSCI World ex USA SRI Index, which systematically excludes companies involved in a range of fossil fuel activities. These exclusions encompass businesses engaged in the exploration, extraction, production, manufacturing, or refining of coal, oil, or gas, as well as those that generate or transmit electricity from fossil fuels, or are involved in natural gas transmission, or hold significant carbon reserves, all as defined within the broader World ex USA Socially Responsible Investment Index.
