Why Invest

The Green Century Balanced Fund provides individuals with a way to invest in stocks and bonds in one mutual fund. The Green Century Balanced Fund keeps your dollars out of fossil fuel companies and other environmentally harmful companies so your investment can align with your environmental values.

The Balanced Fund is actively managed and has the majority of its fixed income portion in green and renewable bonds, which finance environmental protection projects around the globe.


The Green Century Balanced Fund seeks capital growth and income from a portfolio of stocks and bonds which meet Green Century Fund standards for corporate environmental responsibility.

Investment Strategy

The Balanced Fund is an actively managed fund comprised of equities and fixed-income securities. It typically holds 60% to 70% of its net assets in multi-cap stocks and 30% to 40% in investment-grade quality bonds. The Green Century Balanced Fund seeks to invest in well-managed companies.

The Balanced Fund was an early investor in green bonds and now has over 73% of its fixed-income portfolio in green and sustainable bonds.[1]

The Balanced Fund also gives retail investors access to an institutional quality investment process from Trillium Asset Management, a leader in socially responsible investing since 1982.

Fundamental Analysis and ESG Integration:

  • The Fund’s Subadviser uses quantitative measurements in combination with in-house and third-party research to analyze the stocks of companies identified using Green Century’s environmental criteria, and the Subadviser’s own proprietary ESG integrated investment process, and includes in the Fund’s portfolio those companies that appear to possess superior earnings growth prospects and whose stock prices, in the Subadviser’s opinion, do not accurately reflect the companies’ value. The Subadviser’s ESG-integrated investment process includes both industry benchmarking and in-depth company analyses that covers both quantitative and qualitative considerations.
  • Bonds are included in the Fund’s portfolio to balance or offset risks associated with the Fund’s investment in stocks.

A sustainable investment strategy that incorporates environmental, social, and governance criteria may result in lower or higher returns than an investment strategy that does not include such criteria.
