1.5°Climate Strategies Group

The 1.5°Climate Strategies Group (1.5°CSG) is a nationally recognized donor collaborative that is focused on identifying a comprehensive range of impactful and equitable climate solutions and mobilizing the necessary resources to rapidly catalyze and scale up these solutions. Our organization prides itself on promoting collaboration as a means of effecting meaningful change.

The 1.5°Climate Strategies Group hosts biweekly organizational quick pitches enabling members to make catalytic climate investments in a wide variety of organizations working in the nexus between climate and policy. We elevate for donors pre-vetted tax deductible 501(c)3 organizations, non-profit 501(c)4 organizations, Political Action Committees, direct candidate contributions, and for profit ventures. Our goal is to provide a wide variety of investment options to members that can deliver gap filling and catalytic climate impacts.

Whether they have signed the 1.5°Climate Pledge or not, our members are committed to doing what they can to move the climate needle in this decade, with an open mind to a variety of climate strategies. Membership is free.

Our current membership of over 250 people includes board members and staff of Wallace Global Fund, National Education Association, Mertz Gilmore Foundation, Preston-Werner Foundation, donor advisors for wealthy individuals, as well as many successful entrepreneurs, investors, and other climate donors.

1.5°Climate Pledge

We invite foundations and individual donors to sign a pledge to contribute at least 1.5 percent of their net assets annually, through 2030, towards philanthropic efforts that will help limit global warming to 1.5°C.

According to the latest IPCC assessment report, we need to dramatically accelerate efforts over the next few years to reduce greenhouse gas emissions, otherwise the pathways to limit global warming to 1.5°C or even 2°C will be closed for us. We need to deploy private and public capital to speed up the transition from a fossil fuel dependent global economy to a carbon neutral, clean economy. We need philanthropic giving to educate and inform the public, build a clean energy policy environment, create markets for low-carbon technologies, catalyze R&D for decarbonization solutions, assist in the rapid transition in developing countries, and protect environmental and climate justice along the way.

However, the philanthropic community allocates less than two percent of its grants to climate change mitigation. Let’s take private foundations as an example. On average, they give out 7-8% of their net assets annually. Two percent of that would be a mere 0.15% of their net assets. Considering the dire consequences of climate change and its ramifications on healthcare, equity, food security, peace and almost all other philanthropic priorities, 0.15% is an unconscionably small percentage. We need to increase it by an order of magnitude.

From polar bears in the north to penguins in the south and the floods and droughts that concern us all – Greta Thunberg is right — “Our house is on fire.” Habitat loss and fragile ecosystems around the world are real, and their peril is here now. Step up to the biggest challenge of our time, sign the 1.5°Climate Pledge and make the investments needed today to avoid catastrophic climate change and protect our living planet for generations to come.

1.5° Climate Strategies Group is harnessing the power of collaboration to gather the necessary resources for tackling the climate crisis. They have achieved remarkable progress in just a year and a half. Only through collective effort can we mitigate the most severe consequences of climate change.

BILL MCKIBBEN, 1.5°CSG National Advisory Board Member

I have been involved in philanthropy for many years and it has been a great pleasure for me to discover and join the 1.5°CSG. It’s a very strategic and impactful group. They use philanthropy to electrify, amplify, and activate effective and equitable climate actions. The groups they invited for presentations are wonderful and their model of providing 1:1 matches is pretty unique. I have shared information about 1.5°CSG with many friends and will continue to do so!

TERRY GAMBLE BOYER, 1.5°CSG Member

The climate crisis is so immense and urgent that it demands effective global collaborations at all levels. 1.5°Climate Strategies Group sets up a model for individuals and foundations to work together, identify effective projects, deploy philanthropic dollars to help unlock public and private funds, and help ensure the successful implementation of the Inflation Reduction Act.

Climate Justice

The 1.5°Climate Strategies Group acknowledges the disproportionate, negative impacts of fossil fuel extraction and dependence on marginalized communities in the United States and globally. These communities face systemic barriers to accessing crucial resources for a smooth transition to clean energy. As a donor collaborative, we are deeply committed to addressing climate injustices, recognizing institutional racism’s role in sustaining and exacerbating disparities. The 1.5°Climate Strategies Group emphasizes the urgent need to allocate additional financial resources and build capacity for the clean energy transition in disadvantaged communities, striving for a more equitable and sustainable future for all.
