Green Century Equity Fund Proxy Voting Procedures


Introduction

Green Century has established procedures to ensure that its proxy votes on behalf of the Equity Fund (the Fund) are based on the best available knowledge and careful consideration of the best interests of the Fund. Before voting a proxy, Green Century staff conducts a thorough review of the proxy materials, weighing the views of management and any opposing views that are presented. The Green Century staff then recommends a voting position on each issue in the proxy; in making recommendations, the Green Century staff is guided by the Policies and Procedures and strives to make each vote in accordance with them, unless such a vote would not be in the best interests of the Fund. A Green Century corporate officer reviews all recommendations, makes final determinations on a Fund's votes, and signs all voted proxy documents.

Conflict of Interest Policies and Procedures

Where voting on a particular issue on behalf of the Fund may represent a material conflict between the interests of the Fund and the interests of Green Century, Green Century will provide full disclosure, prior to voting the proxy in question, to a committee of the Board, which shall be comprised solely of independent Trustees. The disclosure will include an explanation of the issue, the potential conflict involved, and Green Century's proposed resolution of that conflict. The committee of the Board has the authority to approve or change Green Century's proposed vote on the proxy issue in question. In following these procedures, Green Century's goal is to vote at all times in accordance with the best interests of the Fund and its shareholders.
