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.

Delivering unconditional cash directly to the world's poorest households via secure mobile transfers. 

Since 2009, GiveDirectly has delivered more than $580 million in unconditional cash transfers to families in need. These one-time cash transfers allow recipients to invest in what they need most and have been shown to improve their earnings, children’s school attendance, health, nutrition, and mental well-being.
 
GiveDirectly uses government data to target villages where most or all residents are living in extreme poverty, defined by the World Bank as earning under $2.15/day. In-country GiveDirectly staff enroll one member of each household in the entire village to receive a one-time transfer of about $1,000 USD sent in two installments using mobile money. Recipients can then withdraw the mobile funds as cash with local agents and use the funds to invest in what they need – whether it’s on starting a business, education, making their home safer/sturdier, healthcare, or livestock.
 
GiveDirectly uses rigorous experimental research (randomized controlled trials) to measure the impact of their unconditional cash programs and answer public policy questions, generating evidence on key design and implementation questions across varied contexts. You can find over 300 studies on the positive impacts of cash transfers in GiveDirectly’s Cash Research Explorer.

Evidence Action scales evidence-based and cost-effective programs to reduce the burden of poverty. 

Evidence Action was founded in 2013 to address a big gap in the fight against global poverty – many of the most promising interventions are either implemented at a very small scale, or not at all. We set out to address this gap by building programs that would scale evidence-based and cost-effective interventions, leading to significant improvements in quality of life for hundreds of millions of people.

Our model worked. Since then, our interventions have reached more than 530 million people. This success is achieved through the dedication and talent of our staff, the hard work of our partners, and the commitment of our supporters.

Our Accelerator is the engine for our new program development. To find the most cost-effective solutions in the world, we explore untapped opportunities with the greatest potential for impact. Through a rigorous process, we test groundbreaking health and development interventions, selecting those with a proven ability to reduce the burden of poverty at scale. This focus allows us to maximize the impact made for every single dollar invested.

**Programs:**

**Safe Water Now**

We provide sustained safe water access to communities through water treatment – one of the most cost-effective ways to prevent childhood illnesses and death. Safe Water Now programming in Kenya, Uganda, Malawi, and India uses innovative, low-cost approaches like chlorine dispensers and automatic in-line chlorination. With local government and community buy-in, we reach nearly 10 million people with safe water access and have saved the lives of more than 15,000 children under 5 years old. Now, we are scaling in partnership with the Government of India to reach tens of millions more.

**Deworm the World** 

We help improve children's health, education, and long-term wellbeing by treating parasitic worm

infections at schools. In partnership with governments in Kenya, Nigeria, India, and Pakistan, Evidence Action designs, scales, and sustains cost-effective mass deworming programs. Since 2014, Deworm the World has helped governments deliver 2 billion deworming treatments to children, dramatically reducing worm prevalence and collectively increasing economic productivity by an estimated $23 billion USD.

**Equal Vitamin Access**

We combat the leading cause of childhood malnutrition and disability in low- and middle-income countries by helping to deliver essential supplementation. Equal Vitamin Access provides end-to-end support to governments in India and Malawi to address anemia by leveraging our school-based deworming platform to offer iron and folic acid supplementation cost effectively. In 2023 alone, our program reached 35.8 million children with weekly treatments, giving them a

better chance to develop into strong, healthy adults.

**Syphilis-Free Start**

We safeguard the health of pregnant women and their unborn children by enabling access to low-cost syphilis screening and treatment as part of prenatal care. We partner with governments in Liberia, Cameroon, and Zambia to prevent disability, neonatal

mortality, and stillbirths resulting from congenital syphilis. Syphilis-Free Start’s timely detection and treatment prevented 2,300 adverse outcomes such as blindness, neurological issues, and hearing loss between 2021 and 2023, including 1,300 lives saved.

Evidence Action

We provide cash incentives for childhood vaccinations. It’s one of the most cost-effective ways known to save lives.


New Incentives’ mission is to save lives in a way that does the **most good per dollar**.
Guided by evidence, we provide cash incentives to increase childhood vaccination rates.

- We [raise awareness](https://www.newincentives.org/blog-posts/awareness-activities) about the benefits of childhood vaccinations.
- We [provide cash incentives](https://www.newincentives.org/blog-posts/a-day-in-the-life-abubakar-aliyu-field-officer) at government clinics after children receive vaccinations.
- We [help improve the vaccine supply chain](https://www.newincentives.org/blog-posts/supporting-government-partners-with-vaccine-supply-efforts) to ensure enough vaccines are available at clinics.

Together, these efforts are proven to double vaccination rates and save lives.

One of GiveWell's top charities for the past several years, AMF provides anti-malarial bednets to people in need. 

From Givewell: 
What do they do? AMF (againstmalaria.com) provides funding for long-lasting insecticide-treated net (LLIN) distributions (for protection against malaria) in developing countries. (More)

Does it work? There is strong evidence that distributing LLINs reduces child mortality and malaria cases. AMF conducts post-distribution surveys of completed distributions to determine whether LLINs have reached their intended destinations and how long they remain in good condition. AMF's post-distribution surveys have generally found positive results but have some methodological limitations. (More)

What do you get for your dollar? We estimate that the cost to purchase and distribute an AMF-funded net is $4.95, or $4.65 excluding in-kind contributions from governments. The numbers of deaths averted and other benefits of distributing LLINs are a function of a number of difficult-to-estimate factors, which we discuss in detail below. (More)

Is there room for more funding? We believe that AMF is likely to be constrained by funding. We estimate that AMF could use up to an additional $37.8 million to support LLIN distributions that will occur between now and late 2023. 

AMF is recommended because of its:

Focus on a program with excellent evidence of effectiveness and cost-effectiveness.
Processes for ensuring that nets reach their intended recipients and monitoring whether they remain in homes and in good condition over the long-term.
Room for more funding – we believe AMF will be able to use additional funds to deliver additional nets.
Transparency – AMF shares significant information about its work with us and we are able to closely follow and understand its work.

The Against Malaria Foundation

Prevention, control and treatment of malaria and other communicable diseases among vulnerable populations.

Malaria Consortium US, Inc. (MC-US) is a registered 501(c)(3) public charity and shares the mission of Malaria Consortium, a globally recognized organization committed to reducing deaths and illnesses caused by malaria and other preventable and treatable diseases across Africa and Asia.

Our mission is to save lives and improve health in Africa and Asia through evidence-based programs that tackle malaria and other priority diseases while advancing universal health coverage (UHC). In the US, we build partnerships with foundations, donors, and philanthropic organizations to ensure that every contribution makes a lasting impact for those most in need.

As a leader in malaria control and elimination, our work focuses on interventions such as seasonal malaria chemoprevention (SMC), malaria vaccines, disease surveillance, and integrated child health services. We work in collaboration with governments, communities, and health systems to improve access to essential healthcare and strengthen delivery of services in underserved and hard-to-reach areas.

As a leader in interventions such as chemoprevention and vector control, we rely on evidence and our expertise to deliver established interventions, influence other effective interventions and guide new strategies to reduce the burden of malaria, pneumonia, dengue, malnutrition and diarrhea. We work with communities and all levels of the health system to improve access to and demand for primary healthcare services and overall quality of care.

Our tailored interventions seek to improve equity by providing quality, affordable health services to marginalized populations (particularly women and girls and those living in hard-to-reach areas). To ensure barriers to achieving UHC are addressed and to encourage sustainability, we work closely with governments to integrate our programs within existing health systems and structures in the countries in which we work.

We promote disease surveillance as a core intervention to engage communities to improve the quality and accessibility of routine health information by using digital tools and approaches that strengthen the linkages between case-level data and national health information systems. We combine capacity development at community level with the use of innovative tools and platforms to enhance local capabilities to interpret and use these data most effectively.

All of our work is informed by our core values: accountability, integrity, dignity and equity.
