Wild Animal Initiative

International nonprofit ending the abuse of animals raised for food.

The Humane League (THL) is a global animal protection nonprofit that exists to end the abuse of animals raised for food. Through corporate negotiations, grassroots activism, and policy work, they drive meaningful change across the food industry that reduces the suffering of billions of farmed animals. Their evidence-based approach and dedication to institutional and individual change have made them one of the most effective animal protection organizations worldwide.

**Corporate Impact** The Humane League's corporate negotiations and pressure campaigns have transformed the food industry's treatment of animals. Alongside their partner organizations, THL has fought for—and secured—over [3,000 commitments](https://thehumaneleague.org/article/owa-3000-commitments?utm_medium=blog&ms=c_blog) from companies to spare chickens from abuse. This includes over [2,600](https://chickenwatch.org/progress-tracker/) cage-free welfare commitments and over [625](https://chickenwatch.org/progress-tracker/) broiler welfare commitments by restaurants, bakeries, supermarkets, drugstores, and other foodservice and hospitality businesses. Of these cage-free commitments with a deadline of 2024 or earlier, [92%](https://openwingalliance.org/2025-cage-free-fulfillment-report) have been successfully fulfilled. And, in the US, THL’s work has helped increase cage-free production since 2015. As of 2025, over 45% of the US egg-laying flock is cage-free vs. only 5% when THL started conducting cage-free campaigns in 2015. That 40% difference accounts for an estimated 120 million egg-laying hens per year in the US who will never face life in a cage.

**Global Movement Building** The Humane League founded and leads the [Open Wing Alliance](https://www.openwingalliance.org) (OWA), a global coalition of 90+ animal protection organizations across six continents. The power of the OWA is changing the way the world’s biggest companies treat animals and setting a new standard for corporate animal welfare policies locally—in every major market—and globally. 

**Policy & Legislative Change** Through the [Animal Policy Alliance](https://animalpolicyalliance.org/) (APA), The Humane League works to enact meaningful change for animals through legislation and policy. The APA organizes and empowers an alliance of 30+ local and state-level animal advocacy groups across the US to create relationships with legislators and advocate for policies that benefit animals.

**Evidence-Based Approach** The Humane League grounds all work in research and evidence to maximize effectiveness. Their strategic focus on institutional change creates scalable improvements for the largest number of animals possible, while building momentum for continued progress. Through corporate negotiations, strategic activism, policy advocacy, and movement building, they're creating transformative change for animals in the food system.

Supporting highly-impactful, evidence-based solutions to the triple challenge of climate change, air pollution and energy poverty.

The Founders Pledge Climate Fund exists to leverage each dollar and fund the most effective, neglected climate solutions.

Climate change is an incredibly complex problem borne out of how we produce and consume energy; it's intertwined with challenges of economic development, energy poverty, and emissions-fueled air pollution. It is an environmental and humanitarian crisis we must urgently address.

We aim to take a holistic approach that recognizes the global nature of this challenge and the fact that, despite its urgency, we are still in the early days of climate action. We address the worst-case scenarios of climate damage, and look for solutions that can reduce current carbon emissions and accelerate the transition to clean energy to meet global demand, especially in developing countries. Through the Fund, we:

- Accelerate innovation in neglected technologies
- Catalytically grow the most effective climate organizations
- Promote policy leadership and paradigm shaping

### Our Approach to Grantmaking
When evaluating potential grants, we consider several key points:

- **Counterfactual impact.** Our grants are designed to create a meaningful outcome that would not otherwise have happened. This means that you can rely on the Funds to create meaningful, real change, rather than just maintaining the status quo.
- **Impact-driven philanthropy.** This fund prioritizes the highest-impact solutions to challenges. We assess where the gaps are, which opportunities may be neglected by other funders, and where the biggest wins are in terms of making the biggest difference.
- **The organization’s funding gap.** Not all organizations are set up to scale up their programming and many can’t productively absorb large amounts of unsolicited funding. We evaluate all potential grantees’ capacity for growth and consider how much money they could put to good use.
- **Organizational strength.** Particularly with unrestricted funding, it’s important to have trust in the leadership and capacity of the organizations we support. We look at their track record of success and their transparency about failures as well as successes, and we only support those organizations which are exceptionally well run.
- **Time-critical opportunities and funding certainty.** While Founders Pledge members give to our top climate charities regularly, sometimes there are time-critical opportunities which require fast decisions. We will use the Fund to make grants that enable such short-term opportunities and stability for high-impact funding opportunities thereby increasing the impact compared to individual giving to specific organizations.
- **Portfolio approach.** Because most climate damage comes from particular severe outcomes – with a world of 4 degrees of warming being much worse than twice as bad as a world with 2 degrees – and because every particular strategy – such as energy innovation – might underdeliver, we pursue a portfolio approach to maximize positive impact. This means we will diversify our bets in ways that, when one approach fails (such as energy innovation), the others we promote (such as carbon removal) can be expected to be particularly important and still available.

### 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.

**How frequently will you make grants from the Fund?**
In general, Fund Managers will review grantmaking decisions on a quarterly basis. Decisions will be made based on the value of Funds and the available options for high-impact grantmaking. We may disburse funds outside of quarterly review dates if we become aware of a particularly promising and time-sensitive funding.

**How will my contribution be used?**
All funds are granted out. The Fund is not an investment vehicle. The Fund does not use any percentage of contributions to cover staff time or other overhead costs. Every dollar contributed to the Fund will be used to make grants directly to end-user organizations creating a real difference.

Animal Charity Evaluators helps people help the most animals.

Do you want to help animals but find it hard to decide how? That's understandable. Trillions of animals suffer every day on farms and in the wild. The problem is vast and complex, but people around the world are making a difference.

Animal Charity Evaluators (ACE) is a 501(c)(3) nonprofit registered in the United States dedicated to finding and promoting the most effective ways to help animals. We do this by evaluating and recommending high-impact charities, awarding strategic grants to promising projects, and raising critical funds for the animal advocacy movement. Our ultimate goal is to educate and empower individuals and organizations to make a significant and lasting positive impact on the lives of neglected animals who are often forgotten. ACE envisions a future 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 has a unique and influential role within the effective animal advocacy movement. Our global team is composed of experienced professionals in animal advocacy, effective altruism, and research methodology. To date, we have rigorously evaluated 85 charities that work to end factory farming and create meaningful change for farmed and wild animals, and recommended 38 high-impact organizations as effective giving opportunities. Through our strategic grantmaking, we have distributed nearly $20 million to our Recommended Charities and promising advocacy projects around the globe. Since ACE began tracking this metric in 2014, we estimate that we’ve helped to influence at least $81 million within the animal advocacy movement. Over the years, we have built strong partnerships with organizations and researchers, amplifying our collective efforts to improve the lives of as many animals as possible. 

Join us! Together, we can build a future that's kind to *all* species.
