Bezos Earth Fund backs FireSat with $26 m as climate-fueled wildfires intensify

The Bezos Earth Fund has committed $26 million to Earth Fire Alliance’s FireSat program, supporting the deployment of the world’s first satellite constellation purpose-built to detect wildfires globally as climate change increases the frequency and severity of destructive fires.

The grant, described as the largest philanthropic investment in wildfire detection to date, will help fund the launch and operation of FireSat’s first three operational satellites, scheduled to enter orbit this summer. The funding adds to support from Google.org, the Gordon and Betty Moore Foundation, and other Earth Fire Alliance partners.

FireSat aims to transform wildfire detection:

FireSat is designed to provide earlier and more precise wildfire detection by using advanced infrared sensors capable of identifying fires as small as a beach bonfire within minutes of ignition.

The initial three satellites will monitor wildfire activity at least twice daily across priority regions, including the Amazon Basin, one of the world’s most fire-vulnerable ecosystems.

By 2029, the expanding constellation is expected to detect fires as small as 15 feet by 15 feet anywhere on the planet within one hour. Once fully operational in the early 2030s with around 50 satellites, FireSat will be able to monitor every point on Earth every 20 minutes or less.

Climate, biodiversity benefits:

Wildfires account for up to half of global tree-cover loss annually, while also releasing significant volumes of carbon emissions and harmful air pollutants that can travel across regions and national borders.

According to Earth Fire Alliance, earlier detection could help prevent small fires from escalating into large-scale disasters, protecting communities, forests, and biodiversity while reducing wildfire-related carbon dioxide emissions by an estimated 5% to 10% annually.

Technology backed by global partners:

Developed for Earth Fire Alliance by space systems company Muon Space, FireSat has been shaped through collaboration with fire agencies, researchers, and emergency response organizations worldwide.

A growing number of organizations have already committed to using the satellite data through Earth Fire Alliance’s Early Adopter program, including wildfire management agencies in California, Colorado, Oregon, Texas, Australia, Portugal, several African countries, and organizations operating across the Amazon region.

Bezos Earth Fund expands wildfire resilience efforts:

“During the LA fires, I watched friends and family lose everything. That feeling stays with you and makes you ask: What if we could respond faster?” said Lauren Sánchez Bezos, Vice Chair of the Bezos Earth Fund.

“That’s what FireSat is trying to do, detect a fire anywhere on the planet within 20 minutes, thanks to a constellation of specialized satellites. That’s an investment worth betting on to safeguard communities, preserve nature, and make sure future generations inherit a world that is still vibrant, resilient, and full of possibility.”

Tom Taylor, President and CEO of the Bezos Earth Fund, said the initiative reflects the organization’s focus on scaling innovative climate and nature solutions.

“At the Bezos Earth Fund, we’re focused on supporting innovation that helps solve some of the hardest challenges in climate and nature, and breakthrough technology that addresses the challenges with uncontrolled wildfires is an important area that our funding can help move forward, faster,” Taylor said.

“Advancing detection and prevention technologies such as FireSat have incredible potential to better protect homes and communities, preserve forests and biodiversity, and reduce emissions, and we’re excited to be working together on these areas.”

Building global wildfire monitoring network:

“The Bezos Earth Fund’s commitment to Earth Fire Alliance and the FireSat program sends an unmistakable signal,” said Brian Collins, Executive Director of Earth Fire Alliance.

“With the support of global, high-impact organizations like Bezos Earth Fund—alongside Google.org, the Gordon and Betty Moore Foundation, other funders, and the wildfire community that helped shape this technology—Earth Fire Alliance and FireSat will bring critical new tools to firefighters, scientists, and policymakers in their efforts to strengthen wildfire resilience.”

The investment forms part of the Bezos Earth Fund’s broader strategy to support emerging technologies and innovations aimed at improving wildfire prevention, detection, and response as climate-related risks continue to grow worldwide.
