As a leading global charity, we hold ourselves accountable to our members, the public and all creatures that have a stake in the preservation of the world’s natural resources. And we seek to make use of every dollar donated with careful attention to effectiveness and efficiency.

Our strong performance is reflected in the fact that The Nature Conservancy is highly rated by charity watchdog organizations.


The Nature Conservancy is one of the most effective and efficient environmental organizations in the world.

Building on nearly six decades of experience, we've protected more than 119 million acres of land and 5,000 river miles—and we operate more than 100 marine conservation projects globally.

We are able to accomplish so much because we make careful use of our resources, with 71.2% of our funding going directly toward our science-driven program work. Charity Navigator and the Better Business Bureau applaud program efficiencies above 66%, meaning you can be confident that any investment in The Nature Conservancy will be put to good use.

Be A Conservation Champion

Operating in compliance with our highest corporate value: Integrity Beyond Reproach.

The Nature Conservancy established an Ethics and Compliance Office to help assure that all of its activities are lawful, ethical, and consistent with “Integrity Beyond Reproach,” a core Conservancy value. The Ethics and Compliance Office is staffed by a Chief and a Deputy Compliance Officer. The Chief Compliance Officer reports directly to the Audit Committee of the Board of Directors.

The Office has four core areas of responsibility: training, policy and procedure development and oversight, risk assessment, and investigations of noncompliance. In addition to investigating allegations of noncompliance made directly by staff, the Office manages a Hotline which is available to the public to make anonymous reports of, or inquiries about, compliance issues.

In addition, anyone (for example, grantees, subawardees, or contractors) who has a compliance concern or who knows of or suspects a violation of law by the Conservancy may report the concern to the Conservancy’s Ethics and Compliance Office by e-mailing or by contacting the Conservancy’s Chief Ethics & Compliance Officer:

Renee Kurth
Acting Chief Ethics and Compliance Officer
4245 N. Fairfax Drive
Arlington, VA 22203

The Office provides regular compliance training to every Conservancy employee, members of the Board of Directors, Chapter Trustees, and other volunteer advisors. In 2013, 2014, 2015, and 2016 the Ethisphere Institute named The Nature Conservancy one of the World's Most Ethical Companies.

Code of Conduct
At The Nature Conservancy we value above all else the highest ethical conduct of all employees, Board members, Chapter trustees and other volunteers. The Conservancy is guided by five organizational values: Integrity Beyond Reproach; One Conservancy; Respect for People, Communities, and Cultures; Commitment to Diversity; and Tangible Lasting Results. These values are reflected in the Conservancy’s Policies and Standard Operating Procedures, which are incorporated into this Code of Conduct.

As part of our Code of Conduct, every Conservancy employee and volunteer acting on behalf of the Conservancy is expected to comply with all applicable laws, rules, and regulations in every country, state, or locality in which the Conservancy operates. If there is a conflict between the law and Conservancy policies, employees and volunteers are expected to comply with the stricter of the two unless to do so would be a violation of the law. Employees and volunteers are expected to comply with this Code of Conduct and are required to report, promptly, any violations or perceived violations.

Policies and Procedures
In addition to its Code of Conduct, the Conservancy has a Policies and Procedures Manual that provides clear direction to achieve the Conservancy's mission in accordance with the highest legal and ethical standards. Compliance with the Manual is overseen by the Ethics and Compliance Office. The Manual includes, among others, policies and procedures on Conflicts of Interest; Confidential Information; Lobbying Limitations; Participation in Candidate Elections; Reporting Suspected Violations of Law or Policy (Whistleblower Policy); Equal Employment Opportunity, Affirmative Action, and Diversity; Workplace Harassment Prevention and Reporting; and Records Management.
