Catalyzing resilient solutions, scaled to meet the climate challenge.

CATF is a nonprofit organization dedicated to reducing atmospheric pollution through research, advocacy, and private sector collaboration.

Clean Air Task Force

We do foundational mathematical research to ensure smarter-than-human artificial intelligence has a positive impact.

The Machine Intelligence Research Institute is a research nonprofit studying the mathematical underpinnings of intelligent behavior. Our mission is to develop formal tools for the clean design and analysis of general-purpose AI systems, with the intent of making such systems safer and more reliable when they are developed.

The field of AI has a reputation for overselling its progress. In the “AI winters” of the late 1970s and 1980s, researchers’ failures to make good on ambitious promises led to a collapse of funding and interest in AI. Although the field is now undergoing a renaissance, overconfidence is still a major fear; discussion of the possibility of human-equivalent general intelligence is still largely relegated to the science fiction shelf.

At the same time, researchers largely agree that AI is likely to begin outperforming humans on most cognitive tasks in this century. Given how disruptive domain-general AI could be, we think it is prudent to begin a conversation about this now, and to investigate whether there are limited areas in which we can predict and shape this technology’s societal impact.

Researchers at MIRI tend to be relatively agnostic about how the state of the art in AI will change over the coming decades, and how many years off smarter-than human AI systems are.

CHS at Johns Hopkins advances policy, science and technology to protect people’s health from epidemics and disasters.

The Johns Hopkins Center for Health Security explores how new policy approaches, scientific advances, and technological innovations can strengthen health security and save lives. Our research focuses on improving organizations, systems, and tools to prevent and respond to outbreaks and other public health crises. We advance policies and practice addressing a range of challenges, including the global rise in emerging infectious diseases, a continued risk of pandemic flu, major natural disasters, and the potential for biological accidents or intentional threats. Interdisciplinary and international collaborations with other experts and policymakers improve and inform our work.

The Top Charities Fund supports the highest-priority funding needs among our top charities.

We find and recommend outstanding giving opportunities and publish our research to help donors give more effectively and with greater confidence.

All donations here support our Top Charities Fund. Donations to the Top Charities Fund are granted on a rolling basis to support cost-effective funding opportunities at our top charities. We use our latest research to grant the funds to the top charity (or charities) where we believe they’ll do the most good.

Animal Charity Evaluators helps people help the most animals.

Animal Charity Evaluators (ACE) is a 501(c)(3) nonprofit registered in the United States with a globally distributed team dedicated to impactful animal advocacy. Our mission is to find and promote the most effective ways to help animals. We work toward that mission by evaluating charities, sharing our findings, awarding grants to organizations and promising projects, and fundraising for our recommended charities and grantees. Our organization opposes all systems of oppression and recognizes that they are connected and mutually reinforcing. Ultimately, our vision is a world in which no individual is given less than full moral consideration on the basis of any morally irrelevant feature of their identity, including species membership.

ACE is proud to be considered a leader in the effective animal advocacy movement. Our research comparing the different approaches to reducing the suffering of animals has led to rigorously reviewing charities that work to end factory farming and create meaningful change for farmed and wild animals. Through our Recommend Charity Fund, we have raised and distributed $8.1M to our effective recommended charities. Our Movement Grants program has awarded $5.3M to promising animal advocacy projects around the globe. Since we began tracking this metric in 2014, we estimate that ACE has helped to influence nearly $60M within the animal advocacy movement.

Thanks for helping ACE help animals!

Animal Charity Evaluators

We implement projects aimed at doing the most good in terms of reducing suffering.

Most of us want to make a difference. We see suffering, injustice and death, and are moved to do something about them. But working out what that ‘something’ is, let alone actually doing it, can be a difficult and disheartening challenge.

Effective altruism is a response to this challenge. It is a research field which uses high-quality evidence and careful reasoning to work out how to help others as much as possible. It is also a community of people taking these answers seriously, by focusing their efforts on the most promising solutions to the world's most pressing problems.

Effective Altruism Foundation 

We are a think tank dedicated to figuring out the best ways to make the world a better place.

Rethink Priorities is a research organization that conducts critical research to inform policymakers and major foundations about how to best help people and nonhuman animals in both the present and the long-term future.

Our research spans everything from animal welfare to the threat of nuclear war. We explore neglected but promising areas to improve the world and try to further build the community of researchers working on understanding how to do this most effectively.

If you'd like to support one of our fiscally sponsored projects (e.g. Epoch), you can give via Every.org, and let us know how to allocate your gift at info@rethinkpriorities.org.

Rethink Priorities

The world's-first funding vehicle to collectively grow our resources to support the long-term flourishing of humanity. 


Join this first-of-its-kind philanthropic fund designed for the long-term future. Our Patient Philanthropy Fund addresses a crucial gap: humans spend too little on protecting and benefiting our future generations. However, we can positively affect the lives of our descendants, and avoid major catastrophes that could destroy their future.
 
Contributions are invested for long-term gains, initially in a low-fee Global Stock Index Fund. When a critical time, need, or opportunity arises, we step in to make a grant. Taking a patient approach allows us to wait for a point in time when the highest-impact opportunities are available, which may be years, decades, or even centuries ahead.

### Our Approach to Grantmaking
We're not designed to be a frequent grantmaker; we are primarily an investment account until we reach an extraordinary time and opportunity. Until those moments arise, each year we will make small grants at less than 1% of the Fund's size to the best available opportunities we are able to find in that year. These small grants will build up our grant-making infrastructure and track record. Grant decisions will be made by a dedicated management committee, all with a strong network and expertise on how well-timed grant-making can safeguard the future.

### Frequently-Asked Questions
**Can charities apply for money from the Fund?**
The Funds do not generally accept applications from charities, and we request that charities do not send unsolicited applications for funding. If the Fund Managers choose to open up an application round, this will be publicized.
