September 2, 2015

Dear Mr. President,

The moment of truth for your climate legacy has arrived.

More than four years ago, you received an open letter from some of the nation’s top planetary protection leaders urging you and the president of China to publicly declare a global climate emergency by committing our respective nations to 80% carbon cuts by 2020.

Because that urgent call was not heeded, we have lost precious time in the race to save civilization and must now set our sights even higher. It is with a deepening sense of dread over the fate of humanity that we call on you today to use the powers of your presidency to champion a U.S. goal of net zero greenhouse gas emissions by 2025.

Innovating our way to zero emissions through an all-hands-on-deck societal mobilization at wartime speed is not only our best hope for averting climate catastrophe – it is key to revitalizing our economy and putting America back to work.

In three months, you and leaders from more than 190 nations will gather in Paris for the UN Climate Conference to negotiate a global climate accord. Intergenerational justice demands that the centerpiece of that accord be zero emissions, a goal UN Secretary-General Ban Ki-moon calls “ambitious but achievable.” Three months is ample time for your administration to draft a legally binding zero emissions commitment for Paris.

As you know, Pope Francis wrote in his recent encyclical: “Reducing greenhouse gases requires honesty, courage and responsibility, above all on the part of those countries which are more powerful and pollute the most.” Since the U.S. historically contributed the most to global climate pollution, and is in the strongest position to respond, we have a moral imperative to lead the zero emissions charge in Paris.

The current weak U.S. target of 26-28% carbon cuts by 2025 cannot be described as honest, courageous or responsible in the face of a crisis that threatens the continued existence of humanity. To pretend otherwise is to recklessly gamble with the fate of future generations.

For the sake of our children, and those to follow, it is time to stop promoting “All-of-the-Above” and start protecting all that we love.

President’s Climate Legacy Hinges on Launching
Emergency World War II-Scale Climate Mobilization

September 2, 2015 (New York City, NY) – As President Obama witnessed the dramatic effects of climate chaos in Alaska today, a distinguished group of scientists and environmental, faith, civic and cultural leaders challenged him to champion a courageous U.S. goal of net zero greenhouse gas emissions by 2025 at the upcoming climate talks in Paris.

The challenge, issued in the form of an open letter, describes the current U.S. target of 26-28% emissions reductions by 2025 as a “weak” goal “that cannot be described as honest, courageous, or responsible in the face of a crisis that threatens the continued existence of humanity.” The letter also calls on the Obama administration to abandon its “all-of-the-above” energy policy.

Notable signers include authors Lester Brown and Terry Tempest Williams; actors Mark Ruffalo and Ed Begley, Jr.; environmentalists David Suzuki, Winona LaDuke, Tim DeChristopher and Yeb Saño; filmmaker Josh Fox; musician Moby; and scientist Ove Hoegh-Guldberg, a coordinating lead author for the IPCC’s 5th Assessment Report.

The open letter references a 2011 letter sent to President Obama – and signed by some of the same leaders – that called for...
