THE OTHER HALF OF THE CLIMATE PROBLEM SOLUTION.
Super pollutants are causing half of current climate change and are the fastest way to reduce global temperatures. As the world continues to warm, harming our communities and ecosystems, super pollutants are our climate emergency brake.

CARBON DIOXIDE
makes up around half of current climate change. It’s particularly critical for long-term temperatures, but it’s not the full story. Reducing CO2, can cut warming by a maximum of 0.1°C by 2050.
THE OTHER HALF
includes methane, black carbon, nitrous oxide, f-gases, and tropospheric ozone that are warming the planet fast. Cutting them now, alongside CO2, could slash warming by 0.3°C by 2050.
We envision a world where rapid, substantial reductions in super pollutant emissions minimize climate damages in the near and the long term, while delivering health benefits and building resilience in communities worldwide.

We strengthen the global super pollutant ecosystem and accelerate emissions reductions by advancing philanthropic learning and collaboration, building capacity, and addressing barriers to action.
Pillars Of Our Work
By 2028, we aim to double philanthropic funding to super pollutant action and ensure that effective strategies are being implemented by kick ass institutions across all pollutants, geographies, and sectors. We will achieve these outcomes by advancing four pillars of work.
Develop Under-Developed Areas
We advance effective strategies in under-developed areas (sectors, pollutants, regions) and build organizational capacity to implement strategies, prioritizing expansion of existing organizations over creating new ones.
Support Funder Learning
We regularly convene donors to facilitate learning and coordination. We support funder engagement by promoting effective strategies, improving under-developed strategies, and expanding integration with decarbonization efforts.
Build The Ecosystem’s Profile
We strengthen super pollutant communications through improved messaging, targeted campaigns, and enhanced capacity. We elevate the ecosystem’s profile by hosting events that build trust and connect partners with funders and governments.
Tackle Evidence Barriers To Action
We establish a shared super pollutant knowledge base with the ecosystem. Where there are specific knowledge or evidence barriers to action, we grow scientific capacity and support filling key scientific, economic, and health evidence gaps.
Meet Our Team
We have a small and growing full time staff who bring expertise in super pollutants and non-profit operations. We also work with a set of part-time advisers who add technical expertise in key areas.

As Executive Director, Claire draws on her experience advancing climate solutions within government, civil society, start-ups, and academia. Most recently, Claire served as a Senior Advisor to the U.S. Special Presidential Envoy for Climate, John Kerry, where she led the team that launched and implemented the Global Methane Pledge, the Global Fertilizer Challenge and other international efforts to tackle super pollutants.

As Director of Operations & Impact, Cassidy draws on her experience building operational excellence across nonprofits, consulting, and purpose-driven companies. Most recently, she served as Head of Operations & Finance at August Public, managing operational strategy while leading organizational culture transformation projects for global organizations focused on scaling big ideas to lasting change.
Our Funder Leadership
We work closely with a group of leading climate and health philanthropies who guide our strategy and engage their peers to advance the mission of the organization.

Our Partners
We work in partnership with peer organizations across the super pollutant ecosystem to accelerate coordinated and effective strategies for addressing the other half of warming.
