For decades, climate funding and carbon‑credit markets have relied on centralized institutions, lengthy grant cycles, complex certification bodies, and often opaque verification processes. This top‑down model tends to be bureaucratic,  expensive, and slow — effectively excluding small community‑led or grassroots ecological projects that need funding most.

Moreover, mounting evidence suggests that the vast majority of carbon credits issued by traditional systems don’t deliver meaningful climate impact. A recent review concluded that many offset schemes suffer from systemic flaws — over‑crediting, non-additional or impermanent projects, leakage, and double counting — meaning credits frequently fail to reduce greenhouse‑gas emissions. 

In short, there’s a fundamental credibility and trust problem. Many credits may look good on paper, but rarely guarantee real, long-term reductions in emissions or ecological regeneration. 

Why Web3 Offers a Better Foundation

Ethereum and the wider Web3 space provide properties — transparency, immutability, decentralization, automation — that directly address the flaws of legacy climate‑funding models.

• Every credit, transaction, and lifecycle event (issuance, transfer, retirement) can be recorded on a public, tamper‑proof ledger, such as Ethereum — making it possible for anyone to audit, verify, and trace credits.
  
  
• Smart contracts and onchain automation reduce reliance on middlemen, lower administrative costs, and accelerate issuance/trading/retirement of credits — making smaller, community‑level, and frequent ecological initiatives viable.
  
  
• Standardization and interoperability are easier: credits from different geographies or project types can follow common protocols, enabling composable, scalable ecological markets. 

Over the past five years, a wide range of ecological projects have been built in Web3. Some of these projects are now maturing, pointing millions of dollars of funding to ecological projects around the world. These solutions combined are creating a new, more effective, and transparent framework for effective climate action at scale. 

Spotlight: Regen Network — Putting Ecological Integrity Onchain

When discussing blockchain-powered ecological credits, the first name that comes to mind is Regen Network, a blockchain-based platform for issuing, trading, and governing science-backed ecological credits to power regenerative economies and climate solutions.

Built as a blockchain-based platform, it provides a registry, proven methodology frameworks, and a marketplace for ecological credits tied to real-world environmental restoration: carbon sequestration, biodiversity recovery, soil health, water stewardship, and more. 

Since 2020, Regen Network has retired hundreds of thousands of carbon credits, and new ones have been issued, impacting many millions of hectares worldwide.

While initially built as a standalone blockchain is now evolving into into a bundle of open coordination utilities for the Ethereum ecosystem—technical and semantic infrastructure dedicated to ecological and social regeneration.

As the team realized that “only on Ethereum can coordination, capital, and legitimacy converge at scale, ”they decided to prioritize the development of the Regen Claims Engine, a semantic bridge between Ethereum’s Open Intents and real-world ecological action — a shared grammar for verifiable regeneration.

Once finalized, any organization or wallet should be able to fund, verify, and reward real-world regeneration through Open Intents on Ethereum or any L2. This foundation, paired with impact metadata solutions such as Hypercerts, will turn Ethereum into the primary coordination layer for onchain ecological action. 

Spotlight: Silvi — Bioregional Reforestation & Regeneration in Practice

Silvi seeks to make ecological regeneration a viable livelihood for communities, rooted in local action but open to global funding. It bridges the gap between grassroots stewards and global climate capital. 

On the Silvi platform, local stewards (farmers, community members, land managers) can plant native trees, document geolocation, species, growth, and track ecological stewardship over time. Rather than relying on upfront grants, Silvi links payments to verifiable ecological outcomes: tree survival, biodiversity improvements, community engagement, long-term stewardship. 

By funding based on real impact — not promises — Silvi aligns incentives: communities are rewarded for ecological success, not just intent. And because blockchain reduces overhead, projects that would traditionally be too small or remote become viable recipients of global support.

In November 2025, Silvi announced the Bioregional Reforestation Grant Round, the largest blockchain-native, outcomes-based reforestation grant round yet. The program, which is part of Gitcoin’s GG24, distributes over $100,000 USD in outcome-based reforestation rewards on Celo to communities around the world. 

The donation phase of the program is open until the end of 2025. 100% of the donations are allocated to proven reforestation, so consider donating if you want to help make an impact.

Ethereum as the coordination layer for global climate action

By combining onchain infrastructure (blockchain, registries, smart contracts) with ecological finance solutions such as Regen Network and Silvi, we may be witnessing the emergence of a new paradigm in climate and ecological action.

• Instead of opaque carbon‑credit schemes with dubious impact, we get traceable, verifiable, accountable ecological credits grounded in measurable outcomes.
  
• Local stewards, indigenous communities, and grassroots land managers can finally access global capital, making climate finance inclusive, equitable, and community‑driven.
  
• Real ecological regeneration becomes investable and scalable: forests, soils, biodiversity, watersheds — across geographies — can be financed based on actual ecological data.
  
• The gap between money and impact shrinks: funders get transparent accountability; communities get fair compensation; the planet gets real restoration.

In a world increasingly skeptical of “greenwashing” and hollow offset claims, onchain ecological finance on Ethereum offers a credible, scalable alternative. It aligns economic incentives with ecological reality — and may lay the groundwork for a regenerative rather than extractive global economy.
