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

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.

Conflicts of Interest

  • Policy

    It is the policy of the Conservancy to identify conflicts of interest involving Covered Persons (as defined in the Conflict of Interest Standard Operating Procedure) as well as situations that may give rise to an appearance of a conflict of interest and to address such conflicts and situations in a manner that fully protects the integrity and reputation of the Conservancy.

    The purchase or sale of real estate (or any interest therein) from or to any Related Party is specifically prohibited. For this purpose, a “Related Party” includes

    1. Any individual who is, or was at any time during the 12-month period ending on the date of the purchase or sale, a member of the Board of Directors, a Trustee, or an employee of the Conservancy;
    2. Any individual who is a close relative of such an individual; or
    3. An entity in which the individual owns and/or his close relatives own directly or indirectly more than five percent of the equity interest therein.
  • Purpose

    To assure and ensure that the Conservancy will live up to its high fiduciary obligations and operate in compliance with our highest corporate value: “Integrity Beyond Reproach.”

  • Origin

    Approved by the Board of Directors June, 1995. Revised March 15, 1996, October 2, 2002, and March 12, 2004. Revised to incorporate the former "Sales To or From Related Parties Policy" (approved on June 13, 2003) and approved on January 30, 2009.

The Conservancy has committed to work with other like-minded organizations to develop sustainable investment policies.

For decades, The Nature Conservancy has recognized that the private sector plays an important role in advancing our conservation mission. Businesses around the globe can, and do, have significant impacts on our climate and on the lands and waters that people and nature rely on for survival. For this reason, around the world, we are pursuing strategies to help companies ease their environmental footprints by reducing carbon emissions, properly valuing nature and the services it provides, and investing in protecting and restoring the natural systems that sustain us all.

In managing its long-term investment assets, the Conservancy utilizes a number of professional external investment managers to create and manage its investment portfolio, targeting a prudent balance between risk and return. The Conservancy actively encourages investment managers to consider using environmental, social, and governance (“ESG”) criteria in the investment decision-making process. The Conservancy selects highly capable and proven investment managers willing and able to manage a portfolio within a specific asset class, and seeks to do so consistently with our mission. Specifically, we strive to employ managers who use ESG criteria to inform investment decisions, thereby helping to direct investment dollars toward companies ranking positively on sustainability measures. Additionally, the Conservancy excludes certain investment opportunities from the investment portfolio when deemed inconsistent with its mission.

The Conservancy believes that the prudent management of environmental issues is a potential source of creating value for investors. In general, companies that are successful in avoiding environmental risks, and also at identifying and capitalizing on sustainability opportunities, should reap economic benefits over time. Therefore, we believe the above approach is consistent with our fiduciary requirements to prudently manage risk and return, while also paralleling our conservation mission and our support of sustainability-minded corporations.
