20 oz Green Tumbler

Support our Fall drive to protect public lands

Trump and his corporate polluter allies are moving fast to roll back decades of public land protections. With crucial midterm elections around the corner, building a strong grassroots defense right now is essential to holding polluters accountable and defending our wild places in Congress. We're launching our Fall Drive to power our legal fights and on-the-ground organizing. Be one of the 640 Sierra Club donors we need for this drive to help protect millions of acres of public lands across the country.

Your gift will help Sierra Club:

  • Protect national forests, parks and public lands for future generations
  • Challenge pro-polluter policies in court and hold decision-makers accountable 
  • Fight to preserve our national monuments from all threats
  • Ensure clean air and water for everyone
  • Secure stronger, lasting climate protections

Please, protect our public lands' future and support all of our critical work with a donation today. You'll get our stainless steel 20 oz Sierra Club tumbler when you give $15 or more!

Frequently asked questions
Is my donation tax-deductible?

No. As a C4 non-profit organization, our donations allow us to lobby for environmental protections and to litigate against our biggest threats. However, this tax distinction — while giving us a broader range to enact change — also restricts gifts from being tax deductible.

How can I see how my donation is being used?

86¢ of every dollar donated goes straight to the implementation of conservation programs. This can include campaigns to protect and restore habitats, lobbying for environmental justice, and litigating against entities that are destroying our land, air, and water.

What is Sierra Club's mission?

To explore, enjoy, and protect the wild places of the earth;

To practice and promote the responsible use of the earth's ecosystems and resources;

To educate and enlist humanity to protect and restore the quality of the natural and human environment;

And to use all lawful means to carry out these objectives.
