Sierra Club Praises UN Ban on Nuclear War, Continues Call for Elimination of All Nuclear Weapons

Washington, DC — The Sierra Club hails the announcement from the United Nations that the Treaty on the Prohibition of Nuclear Weapons (TPNW) is now international law, following the ratification of the treaty by Honduras, the 50th country to do so. Since 1945, nearly 100,000 nuclear weapons have been manufactured, costing trillions of dollars and destroying communities and the environment through the mining, refining, and weaponizing of uranium.

Sierra Club congratulates the International Campaign to Abolish Nuclear Weapons, ICAN, our affiliate, and the hundreds of other international groups which have accomplished this long sought legal prohibition of nuclear weapons.

The Sierra Club continues to oppose the creation and testing of nuclear weapons.

In response, Sierra Club Nuclear Policy Director John Coequyt released the following statement:

“The Sierra Club welcomes the ratification of this landmark international treaty, and stands with all nations that recognize the threat that nuclear weapons pose to all life on Earth. We continue to call for an elimination of all nuclear weapons worldwide."

“The manufacturing and storage of nuclear weapons and the nuclear arms race are inherently dangerous. All aspects of nuclear weapons, from their manufacture and storage, to their testing and usage, pose an unacceptable risk to every community and our environment.”
