Reuse to reduce
Climate innovators are developing plans to transition existing infrastructure to produce emissions-free energy.

Climate Fund

Become a high-impact climate philanthropist.

You donate. We research and analyze extensively, making grants to highly effective charities and projects. Every dollar of your donation is leveraged to achieve the greatest possible impact in the fight against climate change.

What we do

We find and fund impactful, neglected climate solutions

Let’s improve how the world fights climate change. We make targeted philanthropic grants to build a global climate response that is more robust, diversified, and future-proof.

We fill gaps and blindspots

The mainstream climate response often important climate solutions (see here for past examples). We analyze the funding landscape and seek out the best opportunities that are neglected by others.

We prioritize impact

We tackle climate change as the global, long-term challenge it is, focusing on solutions that change trajectories and transform systems. This requires us to confront many unknowns in the climate space. Here's how we do it.

We’re creating tools that help assess and compare opportunities to make our grantmaking more effective and efficient.

We minimize damage

Climate change is causing devastating damage around the world, and it's expected to get much, much worse. In fact, it becomes as it gets more extreme.

We plan for worst-case scenarios, aiming to reduce the biggest risks, and look for solutions that will be effective if everything goes wrong. Learn more.

Paths to Impact

Mitigate political risk

Climate progress requires sustained government action, but policies are vulnerable to elections and political division. We fund efforts (and are exploring opportunities around the world) to build bipartisan support, making essential climate policies more resilient, no matter who’s in office.

Leverage resources

Some of the most promising solutions don’t get the attention or funding they need. We fund advocacy to bring these ideas into the spotlight, which can shape policy, influence spending, and shift priorities in both government and private sectors.

Avoid carbon lock-in

Infrastructure built today can commit us to emissions-intensive production for decades. We fund efforts to make new infrastructure as low-carbon as possible and look for ways to reduce future emissions from existing systems.

Drive technology innovation

The world needs to decarbonize energy systems and still meet rapidly rising energy demands. We fund efforts to fast-track and deploy low-carbon technologies, such as advanced geothermal and nuclear, to meet this challenge.

Johannes Ackva

Johannes has dedicated much of his adult life to this topic. From a teenage environmental activist to a climate policy expert advising major EU decision makers, Johannes is committed to solving the problem of global energy poverty, while simultaneously reaching net-zero emissions and protecting our planet.

Prior to joining Founder Pledge, Johannes spent five years working in a think tank advising decision makers on climate policy, and conducting academic research into the intersection between effective and feasible climate policies.

Luisa Sandkühler

Junior Researcher

Luisa joined Founders Pledge in March 2021. In her work as a Junior Researcher at Founders Pledge, she focuses on building data tools to understand crucial questions in climate philanthropy, such as estimating funding additionality and neglectedness.

She is studying physics at the Humboldt University of Berlin. Luisa has been a member of the so-called "Aktionsbündnis Klimaschutz" (Action coalition for climate protection) for several years. It is the central dialogue forum for the continuous discussion of positions on climate protection policy between civil society and the federal government. It supports the German federal government in achieving its climate protection goals. She also has been specializing in climate policy and international cooperation as a member of the campaign and editor team of the WWF Youth Germany. In her role, she led international campaigns, met with politicians and decision-makers (among others the German government, the British Delegate for the COP26 and the British Embassy), participated in international climate conferences and helped Fridays For Future to grow from its early stages
