Investment Strategy

Sustainable & Strategic Investments

The Green Century Funds avoids environmentally dangerous industries and instead invests in companies that meet high environmental, social and governance (ESG) criteria. The Funds use the following strategies to pursue competitive returns.

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.

All the Green Century Funds invest in companies that meet high ESG criteria.

Learn more about what ESG does and does not mean in this clarifying piece written by Green Century Funds President Leslie Samuelrich.

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.

The Green Century Funds belief is that investors should have the option to avoid environmentally harmful industries and align their investments with their values. The Green Century Funds do not invest in companies that produce:
  • Tobacco
  • Genetically Modified Organisms (GMOs)
  • Nuclear Power
  • Alcohol, Gambling, and Adult Entertainment
  • Coal, Oil, or Gas
  • Military, Conventional or Nuclear Weapons
Our exclusionary screens are included in our prospectus.
Green Century Funds is one of the first families of fossil fuel free mutual funds in the U.S.
All of our mutual funds avoid:
  • Exploration, extraction, processing, refining, and transmission of coal, oil, and gas
  • Utilities that burn fossil fuels to produce electricity
  • Companies with carbon reserves
Tips to keep in mind when comparing other mutual funds to ours:
  • “Low carbon” is not the same as fossil fuel free. Low carbon investments might invest in coal, oil, or gas fracking companies
  • Only portfolios with zero or “0.00%” in the energy sector would be consistent with fossil fuel free investments
  • Firms can describe their funds as fossil fuel free but only apply that definition to 80% of their investments.  We apply our exclusions to 100% of our stock and bond holdings.

Going Fossil Fuel Free

Why Invest

Research from leading industry analysts suggests that strategically investing fossil fuel free may help shield investors from:

  • Volatility of oil prices
  • Decreased dividends due to capital expenditures on high-cost projects such as offshore and Arctic drilling
  • Devalued or stranded carbon reserve assets

These concerns are just some of the reasons why Green Century Funds has a long-standing investing strategy of avoiding the worst polluting companies and instead seeks to invest in companies that have not driven climate change.

Past performance is not a guarantee of future results.

Avoid Greenwashing

As more investment strategies are marketed as “low carbon” or “climate change solutions,” keep these points in mind:

  • “Low carbon” is not the same as fossil fuel free. Low carbon investments might invest in coal, oil, or gas companies; these portfolios might evaluate carbon emissions, carbon reserves, or the overall carbon footprint of an investment, but they may also still invest in the companies most responsible for climate change, such as fracking companies.
  • Any binding exclusion, such as avoiding fossil fuel companies, should be spelled out in the prospectus. You can review the prospectus of the Green Century Funds here.
  • Only portfolios with zero or “0.00%” in the energy sector would be consistent with fossil fuel free investments. Download our Fossil Free Investing Guide for additional guidance
