Blockchain and Smart Contracts

Blockchain acts as a secure, tamper-proof ledger that enables conservationists to track and verify data, funding, and ownership transparently. It helps prevent fraud, ensures funding reaches the right recipients, and secures land tenure records, preventing disputes that could threaten conservation projects. Smart contracts automate payments for conservation milestones, such as verified reforestation, ensuring efficient and accountable funding distribution. These technologies empower local communities by enabling direct, verifiable payments for conservation efforts, reducing reliance on intermediaries. Blockchain is also valuable in tracking supply chains, authenticating sustainably sourced products, and ensuring traceability from origin to consumer, preventing illegal trade and fraud. Additionally, blockchain can be integrated with monitoring and evaluation frameworks, enabling real-time financial tracking tied to measurable conservation outcomes. Tokenisation of real-world assets, such as carbon credits, biodiversity units, and land rights, provides a new funding model, allowing conservation organisations and communities to unlock financial value from natural assets. While blockchain increases transparency, concerns exist about its environmental impact and integration challenges. However, when used effectively, blockchain strengthens trust, ensures sustainable funding, and enhances accountability in conservation finance.

Discover how your organisation could apply blockchain to build trust, improve traceability, and drive positive conservation impact through the Navigating Web 3.0 Guide for conservationists.

Case Study: GainForest uses blockchain and AI to enable sustainable funding streams for Indigenous and local communities leading environmental projects worldwide. Through a marketplace called Ecocertain, communities create ecocerts to showcase their verifiable conservation work and receive funding directly and in real-time without middlemen. To ensure credibility, GainForest develops an AI impact evaluation system that reviews projects through field data, satellite imagery, and community reports. This system connects donors who want to see real results to local environmental efforts, which enables transparent funding while cutting out bureaucracy. GainForest is also co-creating the Nature Guild, a decentralised autonomous organisation (DAO) that transfers governance to local communities, ensuring nature stewards at the forefront of conservation have final decision-making authority over their own financial flows, knowledge sharing, and resource allocation.

Target 19 - Mobilize $200 Billion per Year for Biodiversity From all Sources, Including $30 Billion Through International Finance

Substantially and progressively increase the level of financial resources from all sources, in an effective, timely and easily accessible manner, including domestic, international, public and private resources, in accordance with Article 20 of the Convention, to implement national biodiversity strategies and action plans, by 2030 mobilizing at least 200 billion United States dollars per year, including by: (a) Increasing total biodiversity related international financial resources from developed countries, including official development assistance, and from countries that voluntarily assume obligations of developed country Parties, to developing countries, in particular the least developed countries and small island developing States, as well as countries with economies in transition, to at least US$ 20 billion per year by 2025, and to at least US$ 30 billion per year by 2030; (b) Significantly increasing domestic resource mobilization, facilitated by the preparation and implementation of national biodiversity finance plans or similar instruments according to national needs, priorities and circumstances; (c) Leveraging private finance, promoting blended finance, implementing strategies for raising new and additional resources, and encouraging the private sector to invest in biodiversity, including through impact funds and other instruments; (d) Stimulating innovative schemes such as payment for ecosystem services, green bonds, biodiversity offsets and credits, benefit-sharing mechanisms, with environmental and social safeguards; (e) Optimizing co-benefits and synergies of finance targeting the biodiversity and climate crises; (f) Enhancing the role of collective actions, including by indigenous peoples and local communities, Mother Earth centric actions2 and non-market- based approaches including community based natural resource management and civil society cooperation and solidarity aimed at the conservation of biodiversity; (g) Enhancing the effectiveness, efficiency and transparency of resource provision and use.
