About Green Century Capital Management

30 years ago, the group of environmental and public health nonprofits that founded Green Century° decided to help people save for their future without compromising their values. It was a simple concept, but one that was only being used by a handful of pioneers in the socially and environmentally responsible investing space.

Since then, Green Century has grown into a leader in the environmentally and socially responsible investing field, providing mutual funds for individuals and institutions to keep their money out of the most irresponsible industries while using Environmental, Social, and Governance (ESG) performance ratings in investment analysis and portfolio construction to invest in corporate sustainability leaders.

More investors continue to choose impact and find new, innovative ways to use the power of investing to create change; with momentum growing every day.

Our three-pronged approach offers investors a way to make an impact in a way that no other mutual fund can.

Investing in sustainable companies: Green Century seeks to invest in environmental innovators and sustainable companies, including companies involved in energy efficiency, renewable energy and sustainable agriculture.

Leading Shareholder Advocacy: Even corporate sustainability leaders have room for improvement, which is why Green Century works with dozens of companies each year to adopt policies around reducing climate change, protecting tropical forests, promoting animal welfare, and safeguarding water supplies.

Support of Environmental and Public Health Nonprofits: One hundred percent of the profits earned managing the Green Century Funds are used to support the environmental and public health work of our nonprofit owners.

The organizations which founded and own Green Century Capital Management are: California Public Interest Research Group (CALPIRG), Citizen Lobby of New Jersey (NJPIRG), Colorado Public Interest Research Group (COPIRG), ConnPIRG Citizen Lobby, Fund for the Public Interest, Massachusetts Public Interest Research Group (MASSPIRG), MOPIRG Citizen Organization, PIRGIM Public Interest Lobby, and Washington State Public Interest Research Group (WASHPIRG).

Green Century is the first family of fossil fuel free, diversified and responsible mutual funds, allowing investors to match their support of a transition to clean energy and sustainable businesses with their investment choices.
