Total philanthropic giving to climate change mitigation from foundations and individuals reached an estimated $11.7 billion to $18.4 billion in 2024.
Even as geopolitical friction continues to strain the global economy, funding for clean energy and climate solutions is experiencing a quiet, record-breaking surge. According to the newly released sixth edition of ClimateWorks Foundation’s Funding Trends report, total philanthropic giving to climate change mitigation from foundations and individuals reached an estimated $11.7 billion to $18.4 billion in 2024. This surge represents approximately 2.1% of global philanthropic giving, crossing the elusive 2% threshold for the first time in history.
While climate mitigation still accounts for a remarkably small share of the overall $940 billion global philanthropic pie, its growth trajectory is outpacing broader charitable giving, which ticked up by a modest 6%. Foundation-specific climate funding alone breached the $6 billion mark for the first time, effectively doubling the $2.3 billion recorded just four years prior in 2020. However, beneath these headline-grabbing numbers lies a complex, shifting landscape marked by localized funding gluts, a sharp retreat from fossil fuel transition strategies in major economies, and a persistent failure to move capital to the Global South.
The anatomy of climate funding reveals distinct strategy shifts. Clean electricity remained the undisputed heavyweight of climate philanthropy in 2024, pulling in $840 million, or roughly 13% of total sector-allocated funds. Interestingly, the vast majority of this capital did not go directly toward hardware or engineering; instead, it was channeled into public engagement, strategic communications, and grassroots movement building to secure a social license for the energy transition.
The year’s breakout story, however, belongs to food & agriculture. Long considered an underfunded corner of climate action, the sector saw a massive 63% year-over-year explosion in foundation funding. This influx was heavily concentrated in people-centered strategies that prioritize agricultural equity, justice, local livelihoods, and behavioral shifts toward sustainable diets. Conversely, philanthropic appetite for directly fighting fossil fuel infrastructure appeared to wane.
Funding for transition fossil, or philanthropic efforts aimed at phasing out coal, oil, and gas extraction, dropped by 15% globally. The contraction was most severe in the world’s two largest carbon emitters: foundation funding for fossil fuel phase-outs plummeted by 80% in China and 75% in the United States.
Despite endless talk of climate equity at global summits, philanthropy is still failing to diversify geographically. 70% of targeted foundation funding was absorbed by just two regions: the United States ($1.7 billion) and Europe ($890 million). Instead of spreading out, this geographic concentration actually intensified by 10% compared to last year.
The report attributes this clustering largely to Western foundations doubling down on domestic portfolios, alongside a wave of European philanthropies entering the climate mitigation space for the first time.
This domestic focus leaves glaring blind spots. Funding to China fell by 30% overall. On a more positive note, Africa and Brazil both recorded 30% increases in foundation funding. In Africa, that growth manifested heavily in the agricultural sector, where funding more than doubled from $30 million to nearly $80 million, a critical buffer as global fertilizer shortages and conflict continue to strain local food security.
Yet, the macro gap persists. The report notes that foundations continue to face rigid structural hurdles when trying to fund the Global South, including board-level restrictions, thin local grantee pipelines, cross-border compliance costs, and limited internal due diligence capabilities.
The ClimateWorks data shows that early indicators for 2025 suggest this philanthropic momentum is holding firm. But with a multitrillion-dollar climate investment gap looming, philanthropy’s true power lies not in trying to foot the bill alone, but in acting as high-leverage risk capital that prepares the ground for public and private markets.
This pivot from funding general climate ambition to demanding hard corporate execution matches a parallel movement in the broader financial world. At London Climate Action Week, the Oxford Martin School and Oxford Net Zero launched the second edition of the Oxford Martin Principles for Climate-Conscious Investment.
First introduced in 2018 and already adopted by institutional investors managing over £62.5 billion, the updated framework directly addresses the still evolving and often confusing maze of corporate net-zero disclosures. It introduces three deceptively simple tests to determine whether a corporate climate plan is actually credible:
As Cameron Hepburn, co-author of the updated principles and Professor of Environmental Economics at Oxford, observed at the launch: The transition now depends less on ambition and more on execution.
To bridge the gap between corporate execution and grassroots reality, ClimateWorks concludes with a sharp call to action for its own peers: change how the money is given. Currently, climate philanthropy remains overwhelmingly dominated by project-restricted grants. Driven by short institutional budget cycles and board preferences for easily quantifiable, near-term metrics, this model leaves advocacy groups and local communities highly vulnerable.
The report emphasizes that true resilience requires a shift toward multiyear, unrestricted funding. Without flexible capital, organizations on the front lines, particularly in the Global South, cannot build the robust organizational infrastructure needed to absorb macroeconomic shocks, retain top talent, or pivot quickly when geopolitical realities shift overnight. Philanthropy has the unique privilege of being nimble; the data suggests it is time to start using it.
Invert Insights.
💡 The shifting tide of climate philanthropy outlined in the report and the parallel evolution of investment benchmarks like the Oxford Martin Principles offer a revealing playbook for the future of the Voluntary Carbon Market (VCM). Historically, philanthropy and the VCM have operated in separate silos: philanthropy focused on advocacy and policy, while the VCM focused on private, market-based transactions. Today, these two forces are converging. Philanthropic capital is effectively acting as the R&D department for the carbon markets, laying the groundwork for high-integrity credits.
💡 Some nature-based solutions projects have faced backlash in the past over land-rights issues, poor benefit-sharing, and a lack of local co-benefits. Philanthropy pouring hundreds of millions of dollars into developing people-centered agricultural frameworks provides a massive, pre-funded social infrastructure. VCM developers can leverage these donor-funded frameworks to build projects that naturally meet the strict community-safeguard requirements of the Integrity Council for the Voluntary Carbon Market (ICVCM) Core Carbon Principles, restoring buyer confidence in land-use credits.
💡 Philanthropy is structurally bottlenecked in the West. This leaves a funding vacuum in developing nations, and the VCM can step in as a primary, market-driven mechanism to bypass these philanthropic bottlenecks. Because carbon finance relies on bilateral, contract-based transactions rather than foundation board approvals, the VCM is uniquely positioned to channel private capital directly to local project developers in regions like Latin America, Africa, and Southeast Asia.
