Mission and programs · 2023

Mission

To advance effective law and governance systems for environmental protection by providing information, publications, training courses, seminars, research and policy recommendations in a manner that engages and empowers leaders and practitioners to advance environmental rule of law. ELI's audience includes environmental professionals in government, the private sector, nongovernmental organizations, affected communities, academia, and others.

  • Research and Policy Division:Provided research, education, training, and technical assistance in environmental law and policy to all sectors in the U.S. and numerous foreign countries. Research programs in 2023 covered the breadth of the field of environmental law and policy, from assessing state protections of nonfederal waters, to promoting good governance to support sustainable management of small-scale fisheries, to operating the Local Government Environmental Assistance Network and the International Network for Environmental Compliance and Enforcement. Other initiatives identified best practices for coastal management programs, provided model ordinances and other tools for reducing food waste, supported development of a protected area proposal for sperm whales, provided evidence-based judicial education on climate science and the law, and researched and analyzed the legal authorities to address plastic pollution, among other things. Our ongoing programs also continued to provide guidance, education, and recognition to environmental professionals nationwide such as through the Environmental Law and Policy Annual Review; training for states, territories, and tribes on the Total Maximum Daily Load and other Clean Water Act programs; our Indoor Air Quality program; our annual National Wetlands Awards program; and others. In addition, among its internationally focused initiatives, ELI analyzed customary water tenure in sub-Saharan Africa; supported the Women in Water Diplomacy Network; and continues to lead in the field of environmental peacebuilding, which integrates natural resource management into conflict prevention, mitigation, resolution, and recovery to build resilience in communities affected by conflict. For a fuller description of our programs, please refer to our annual report, which can be found at www.eli.org.

    Expenses $4,650,000

  • Associates & Education Division: Led 75 events, including conferences, webinars, Breaking News webinars, policy forums, networking receptions, topical conference calls, Eastern and Western Boot Camps on Environmental Law, Summer School seminars, annual Supreme Court preview and review, public seminars and more, for 22,116 environmental professionals (virtually and in person). Topics of discussion ranged, including agriculture, carbon capture, utilization, and storage, careers in environmental law, the Clean Air Act, the Clean Water Act, climate change, climate disclosures, compliance and enforcement, decarbonization, the Endangered Species Act, energy law, environmental criminal enforcement, environmental justice, ESG, federal environmental updates, international environmental law, land use law, the National Environmental Policy Act, PFAS, products regulation, Supreme Court cases, sustainable development, TSCA, and more. For a fuller description of our programs, please refer to our annual report which can be found at www.eli.org.

    Expenses $914,907 · Revenue $551,856

  • Publications Division:Provided timely, accurate, and practical information to environmental professionals through two nationally recognized publications, the Environmental Law Reporter and The Environmental Forum. The Environmental Law Reporter draws premier authors on current legal events, and the Environmental Forum continues to provide award-winning coverage of the environmental profession and environmental policy. In addition, ELI Press advanced the field by publishing five books: TOXIC INTENT: ENVIRONMENTAL HARM, CORPORATE CRIME, AND THE CRIMINAL ENFORCEMENT OF FEDERAL ENVIRONMENTAL LAWS IN THE UNITED STATES; GOVERNING FOR SUSTAINABILITY; PRINCIPAL TRENDS ON BRAZILIAN ENVIRONMENTAL LAW; REMARKABLE CITIES AND THE SECURITY AND SOVEREIGNTY OF FOOD AND NUTRITION: 41 WAYS TO REGENERATE THE LOCAL FOOD SYSTEM; and PFAS DESKBOOK.For a fuller description of our programs, please refer to our annual report, which can be found at www.eli.org.

The first 25 listed. Compensation is as filed in Part VII: reportable pay from this organization and from related organizations, other compensation, and hours per week. The total, marked calculated, is our sum of the three dollar columns, with a blank column counted as $0; the form itself has no total. On a Form 990-EZ the columns are Part IV's instead, and on a Form 990-PF Part VIII's — compensation, contributions to benefit plans, and expense account — and the total sums those. A Schedule J breakdown is as filed: base pay, bonus, other, deferred compensation and nontaxable benefits from this organization, with any from related organizations beside each, and the filer's own total. It is shown with the Part VII listing of the same name on the same return. The form gives no key between the two, so that pairing is ours, and is marked matched by us. Earlier years are each on their own filing page.

Nonprofiteer parses Forms 990, 990-EZ and 990-PF, in a window of recent tax years. These returns are recorded from the IRS e-file index, so their figures were extracted by that index rather than read from the return here — treat them as a different source from the filings above, not as more of the same record. A dash means the index carries no figure; Form 990-T listings carry none at all. Showing the 10 most recent; the API carries the rest.

Grants made

No itemized grants to organizations. Schedule I is filed only by organizations that granted more than $5,000 to a recipient, so most filers have none.

Grants received

The 10 largest by cash amount. The API serves every itemized grant.

Related organizations

From Schedule R Part II, where a filer lists the tax-exempt organizations it is related to by control. It does not record shared board members or money.

Other IRS files

Auto-Revocation List

Not listed. The IRS publishes this list for organizations whose exemption was automatically revoked for failing to file for three consecutive years.

Publication 78

Listed as of 11 November 2026, under deductibility PC.

These are two separate IRS files on two separate schedules, shown as published and not reconciled with each other. Neither is a statement about whether a contribution is deductible today: 19,245 organizations appear in Publication 78 while the IRS's own revocation file lists them as currently revoked, more than half of those revoked before 2019. Absence from Publication 78 is evidence of nothing, and presence is not evidence either. Verify current status with the IRS before relying on it.
