Top Environmental Organizations by Employees

The environmental organizations that employ the most people have between 166 and 4,091 employees, and tend to run environmental education, energy conservation, or natural resource conservation programs (among other types of environmental organizations). The more popular environmental organizations — Nature Conservancy, Greenpeace, Sierra Club, etc. — are present, but the realm of environmental nonprofits is much larger than just environmental advocacy. And geographically these top environmental organizations are distributed throughout the country, with states like Minnesota, Colorado, and Montana having a disproportionate presence.

What is Cause IQ?

Cause IQ is a website that helps companies grow, maintain, and serve their nonprofit clients.

Our data and tools help companies prospect for new business, qualify inbound opportunities, benchmark their clients, and enrich existing information.

Methodology

Cause IQ digitizes and cleans electronic and paper / scanned Form 990s for over 400,000 IRS-registered tax-exempt organizations. We narrowed these to environmental-related organizations, excluding nonprofits that are botanical gardens and pet-focused. Specifically, we are looking at organizations classified within these following NTEE codes, or their subordinates: C30, C50, C60, and D30.

Please contact us if you have any questions on this article.
