Unique Non-Profit Ownership

Today, 100% of the profits we earn from managing the Green Century Funds support the critical work done by those organizations. 

Our owners work at the state and national levels to advocate for the public interest. They speak out for a healthier, safer world where we can pursue our own individual well-being and the common good.
