A new breed of climate-focused NGO working to build a world that removes more carbon than it emits.

Reducing emissions is not enough.

We envision a world where climate change has been halted and economic prosperity is driven by innovative farmers, foresters, and businesses pulling carbon from the sky.

By partnering with experts and change-makers across industries, we elevate three essential pillars of economic transformation: accelerated research, smart business practices, and effective policies.

With so many solutions at our fingertips and so little time, we’re committed to motivating change widely — and fast. We work alongside people of diverse perspectives and backgrounds to build broad momentum for carbon removal.

We protect the rainforests of Central and South America by working with the indigenous communities that call them home.

Human life depends on our rainforests. They are vital to the stability of our climate. Rainforests are carbon sinks that surpass our most sophisticated technology; they absorb 30% of the world’s CO2 emissions each year.

Rainforests are also home to more than half of the world’s animal and plant species.  They are a constant source of life-saving medicines. Millions of indigenous peoples depend on the forest for their survival, including our planet’s last uncontacted cultures.

Despite rainforests importance, they are disappearing. Today, we have lost more than half of earth’s original rainforests—every year we lose an area of tropical forest the size of New York State.

But together we are making a difference. To date, we have protected more than 33 million acres of rainforest. Indigenous communities of the rainforest are fighting back, holding the front line for all of us. With your support, Indigenous communities can protect the forests we all depend on for generations to come.

Supporting young people to make climate change an urgent priority, and exposing corruption of the fossil fuel industry.

The Sunrise Movement is a youth movement to stop climate change and create millions of good jobs in the process. We’re building an army of young people to make climate change an urgent priority across America, end the corrupting influence of fossil fuel executives on our politics, and elect leaders who stand up for the health and wellbeing of all people.

We call ourselves Sunrise because we know this dark hour in America, when fossil fuel executives and climate deniers run our government, cannot last. The sun will rise again.  We have a 4-year plan to make climate action an urgent priority in every corner of the country, expose the fossil fuel executives who have purchased politicians and blocked progress, and lift up champions who will work for the people at every level of government.

We need an all-out mobilization of our economy and society to protect humanity and restore a safe climate.

We are already experiencing catastrophic climate impacts, and they are accelerating. Our climate politics have not kept up with the ever-worsening scientific reports and demonstrated reality. We don’t have 30 years to decarbonize.  We need to reach zero emissions and to reverse the 6th mass extinction through a just transition as quickly as humanly possible.

Climate Emergency Fund has been turbo-charging the climate movement by supporting its most brave and adamant activists since our founding in 2019. We support the people who tell the truth, demand transformation at emergency speed, and put everything on the line to protect humanity and the living world.

We won’t defeat today’s urgent climate crisis with yesterday’s climate politics. The next decade will determine whether America rises to the opportunity of rescuing our future, or shrinks from the challenge of this crisis. We need bold solutions now.
