Public finance for nature reached an estimated $220 billion, according to the UN Environment Programme’s (UNEP) State of Finance for Nature 2026 report.
Based on improved data and more robust methods to track nature-based solutions finance flows in 2023, public finance for nature increased modestly, with biodiversity and landscape protection spending rising and international contributions expanding. These gains reflect growing recognition that ecosystems underpin economic stability, climate resilience, and food security.
While funding for biodiversity and ecosystem restoration continues to rise, it remains significantly outweighed by trillions of dollars flowing into activities that degrade nature. The report estimates that approximately $7.3 trillion annually supports nature-negative activities, including fossil fuel subsidies, environmentally harmful infrastructure, and unsustainable resource extraction. This creates an estimated 30-to-1 imbalance between finance that contributes to environmental degradation and finance that supports nature-based solutions.
Nearly half of the global economy depends on ecosystem services such as pollination, soil fertility, water purification, and climate regulation. Strengthening public finance for nature is increasingly viewed as an economic safeguard rather than solely an environmental priority.
Nature-based solutions include restoring forests, wetlands, mangroves, and grasslands; improving sustainable land management; and protecting biodiversity-rich habitats. These approaches help store carbon, reduce flood risk, support fisheries, and strengthen rural livelihoods.
The report estimates that annual investment in nature-based solutions must increase to roughly $571 billion by 2030 to meet global biodiversity, climate, and land restoration targets. By 2050, funding requirements could rise further as climate impacts intensify.
Public finance for nature currently accounts for most nature-positive spending. Governments provide close to three-quarters of restoration and conservation funding. International climate and biodiversity frameworks, including the Kunming-Montreal Global Biodiversity Framework, aim to guide these investments.
Private investment in nature-based solutions remains comparatively small. While some corporations and financial institutions have committed to sustainability targets, scaling credible investment mechanisms remains a work in progress.
The report highlights that redirecting environmentally harmful subsidies could significantly narrow the financing gap. Public subsidies for fossil fuels, unsustainable agriculture, and resource extraction account for a substantial share of nature-negative finance flows.
Reforming these subsidies would not only reduce environmental damage but also free fiscal space for conservation and restoration. Policy shifts toward regenerative agriculture, sustainable transport, and ecosystem protection can align economic incentives with environmental outcomes.
Public finance for nature is increasingly tied to broader economic reform efforts. Governments are exploring biodiversity credits, green bonds, blended finance structures, and mandatory disclosure of nature-related financial risks. These tools aim to integrate environmental considerations into mainstream financial decision-making.
Scaling finance also requires stronger governance systems. Transparent monitoring, measurable impact reporting, and safeguards for Indigenous rights and local communities help ensure funding delivers lasting benefits.
Many restoration initiatives emphasize ecosystem protection over simple tree planting. Protecting intact forests, wetlands, and grasslands often delivers more reliable climate and biodiversity outcomes than converting landscapes into monoculture plantations.
Public finance for nature is also linked to climate resilience. Restored wetlands buffer flood events. Mangroves protect coastlines from storms. Healthy soils retain water during droughts. These benefits reduce long-term economic losses and disaster recovery costs.
International cooperation remains central to closing the financing gap. Upcoming biodiversity negotiations will assess progress toward agreed targets, including commitments to increase funding and reform harmful subsidies.
The report introduces frameworks to guide transition pathways, encouraging governments and businesses to phase out destructive investments while scaling nature-positive solutions. Aligning public budgets with environmental goals can accelerate systemic change.
The scale of required investment may appear large, but it represents a small fraction of global GDP. Redirecting a portion of existing financial flows could significantly shift the balance.
Public finance for nature has grown steadily over recent years. While the current imbalance highlights the magnitude of the challenge, it also underscores the opportunity. Even incremental reallocation of capital away from harmful activities could deliver meaningful progress.
Ecosystems provide trillions of dollars in economic value annually. Protecting and restoring them supports long-term prosperity, climate stability, and food security.
The State of Finance for Nature 2026 report offers a data-driven assessment of current trends. It identifies both progress and remaining gaps. The findings suggest that scaling finance, reforming subsidies, and strengthening governance are central to aligning global capital flows with environmental goals.
Nature-based solutions investments represent a foundation for broader transformation. As governments refine policy frameworks and financial institutions integrate environmental risk assessments, momentum for nature-positive investment continues to build.
Closing the 30-to-1 gap will require coordinated policy reform and sustained investment. The trajectory of public finance for nature is moving in the right direction, but the pace must accelerate to meet global biodiversity and climate commitments.
