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.

High charity and financial health ratings mean that your support is used efficiently and effectively.
