What is a 501 (c)(3)?

A 501(c)(3) environmental organization is a nonprofit group in the United States that has been granted tax-exempt status by the IRS under section 501(c)(3) of the Internal Revenue Code. This designation allows the organization to operate for charitable, educational, or scientific purposes, and donations made to it are generally tax-deductible for the donor.

When applied to environmental organizations, a 501(c)(3) usually focuses on initiatives such as:

    • Preserving natural areas through land acquisition, easements, or restoration.

    • Protecting wildlife habitats, forests, rivers, wetlands, and coastlines.

    • Teaching communities, schools, and the public about sustainability, ecology, and conservation practices.

    • Offering workshops, field trips, or citizen science programs.

    • Conducting studies on environmental health, biodiversity, climate change, pollution, or restoration.

    • Sharing data to inform policy and community decisions.

    • Organizing cleanups, tree plantings, or water quality monitoring.

    • Encouraging sustainable practices like recycling, native plant gardening, and energy efficiency.

    • Promoting environmentally friendly practices and policies (i.e. clean water, renewable energy, conservation funding).

    • Note: 501 (c)(3) organizations cannot engage in partisan political activity, such as endorsing candidates, but they can advocate for legislation related to their mission as long as lobbying is not a “substantial part” of their activities.
