Top climate nonprofits for donors

Top climate nonprofits

Project InnerSpace

Project InnerSpace

Deep underground, the Earth’s crust holds abundant heat that can supply renewable, carbon-free heat and reliable, on-demand electricity. Project InnerSpace is fast-tracking next-generation technologies that can make geothermal energy available worldwide. It has a bold plan to reduce financial risks for new geothermal projects, making geothermal energy cheaper and more accessible, especially in densely populated areas in the Global South.

Opportunity Green

Opportunity Green

Aviation and maritime shipping are challenging sectors to decarbonize and have not received much support from philanthropy in the past. Opportunity Green pushes for ambitious regulations, promotes clean fuels, encourages companies to adopt greener fleets, and works to reduce demand for air travel. We are especially excited about Opportunity Green’s efforts to elevate climate vulnerable countries in policy discussions, as we think this could improve the inclusivity of the process and the ambition level of policies.

Industrious Labs

Industrious Labs

Heavy industries like steel and cement are the building blocks of the global economy, accounting for one-third of greenhouse gas emissions. Industrious Labs runs comprehensive campaigns to decarbonize specific industries, targeting corporate actors and governments alike. Critically, through coalition building, regranting, and training, it is scaling advocacy well beyond their own organization. We are excited about Industrious Labs’ actionable, industry-specific strategies and the strength of its leadership team. 

Good Food Institute

Good Food Institute

Livestock production is responsible for at least 10% of global emissions – livestock belch methane, require substantial (often deforested) grazing land, and contribute to general supply chain emissions. The Good Food Institute (GFI) seeks to make alternative proteins as affordable and tasty as conventional products. It pushes for more government funding for research, fights for fair labeling, and helps cultivated meat get to market. We think GFI is a powerhouse in supporting alternative proteins, with impressive wins under its belt. 

Good Energy Collective

Good Energy Collective

Wind and solar power are now competitive pieces of the green electricity puzzle, but they can’t do it alone. Good Energy Collective supports nuclear energy as part of an environmentally just climate change agenda. It backs advanced nuclear reactors, which are designed to be safer, cheaper, and more versatile than conventional reactors. We think Good Energy has carved a unique niche in nuclear power advocacy by focusing on the intersection of expanded deployment, community engagement, and justice. 

Clean Air Task Force

Clean Air Task Force

Having had a successful track record of pushing for climate solutions in the US, Clean Air Task Force (CATF) is now going global. By identifying barriers to technology deployment, engaging with stakeholders, and advocating for supportive policies, CATF aims to speed up the growth of low-carbon technologies to reduce emissions broadly and quickly. We are particularly impressed that CATF has built momentum for areas of innovation that need more funding support, such as superhot rock geothermal energy, zero-carbon fuels, and the decarbonization of aviation and maritime shipping. 

How we find effective climate charities

We need systemic change

Addressing the climate crisis requires transforming the very systems fueling unsustainable emissions. In practice, this means advocating for robust climate policy and advancing innovative technologies. We believe donors can have an outsized impact by donating to climate change charities that work directly on policy advocacy and technology advancement.

Tenfold impact

Our research shows that giving opportunities that focus on policy and technology can be an order of magnitude more effective than the best direct emissions reductions projects, such as carbon offsets.

How we find effective climate nonprofits
We follow a five-step research process: identify impact strategies, assess impact strategies, longlist potential organizations, evaluate specific funding opportunities, and publish recommendations. Read more about how we find top climate change charities.
