5 Blockchain Projects Actually Doing Something About Climate (No, Really)
5 Blockchain Projects Tackling Climate Change Issues
When most people hear “blockchain” and “climate” in the same sentence, it’s usually a contradiction or a punchline. Between the energy-hungry mining debates and vague eco-token launches, skepticism is warranted. But beneath the noise, a few blockchain projects are taking the messiness of climate action seriously. No grand promises. No token hype. Just pilot projects in hard places, real data, and infrastructure built for impact, not headlines.
These aren’t whitepapers or metaverse gimmicks. They’re quietly tracking carbon, verifying on-the-ground efforts, and using blockchain not as the solution but as part of the system. Some are flawed, others are still finding their footing, but they’re all showing that crypto can be more than speculation. Here are five projects doing the work.
Fedrok
Fedrok is a Switzerland-based blockchain project focused on climate finance. Unlike most general-purpose chains, it’s built from the ground up as a Layer 1 protocol with a dual-layer validation model called “Proof of Green”, a consensus system that validates blocks based on verified environmental outcomes, rather than computational effort or token holdings. It rewards on-the-ground results instead of computing power or capital stake. FDK, its native cryptocurrency, is designed to reflect real-world climate impact by tying issuance directly to environmental performance, not speculation.
The project is being tested in several environments. In Papua New Guinea, it’s supporting mangrove restoration efforts with stablecoin payouts tied to digital landowner IDs and satellite carbon tracking. In Madagascar, it partnered with the social enterprise Greentsika on a “Cash-for-Trash” waste collection initiative. And in Chad and Niger, it’s piloting USSD-based carbon credit tools designed for communities with limited connectivity and no access to smartphones.
Fedrok holds ISO 9001 and 14001 certifications and is pursuing regulatory membership with Switzerland’s VQF. The combination of low-tech accessibility and institutional compliance gives it a unique position among climate blockchain efforts. Like others in this space, the long-term challenge lies in scaling impact and verification.
Open Forest Protocol
5 Blockchain Tackling
Open Forest Protocol is tackling one of climate’s biggest bottlenecks: verifying whether forests are actually being preserved or restored. The project builds open-source infrastructure for Measurement, Reporting, and Verification (MRV) using blockchain to timestamp and anchor ecological data on-chain, making it harder to fake or lose over time.
Unlike traditional systems that rely on centralized auditors, OFP enables local stakeholders to submit evidence including satellite data and field reports that anyone can review and validate on-chain. The crypto platform is being piloted with reforestation efforts in Kenya, Nepal, and Peru, among others. It’s designed to lower the cost and complexity of MRV, which has historically sidelined smaller or remote forest projects.
By creating an auditable, decentralized MRV layer, Open Forest Protocol hopes to increase trust and access in carbon markets, especially for regions that are usually excluded due to high verification barriers.
KlimaDAO
FedrokOnce seen as a poster child for speculative offset trading,KlimaDAO is trying to rebuild its reputation, this time around transparency. After its rapid rise (and fall) during the peak of tokenized carbon hype, the project has shifted focus from offset bundling to infrastructure tooling. The new version, Klima Protocol, is building registry bridges and dashboards that make it easier to trace the origin, quality, and movement of carbon credits.
One of its key offerings is the Carbonmark platform, an open marketplace for tokenized carbon credits with clearer pricing and provenance data. The goal is to bring clarity to a notoriously murky market, especially the voluntary carbon market where double-counting and low-quality credits have been widespread.
It’s a notable pivot from financialization to accountability. Whether Klima can regain trust is still in question, but its current approach reflects a growing awareness that impact transparency, not just liquidity, will define the next phase of climate-focused Web3.
Regen Network
FedrokRegen Network is building a full-stack ecosystem for regenerative agriculture, combining blockchain, remote sensing, and ecological science to reward farmers for restoring soil health, biodiversity, and water systems. It issues “ecocredits” tied to verified ecosystem services, with a focus on long-term sustainability instead of one-off carbon removal.
Pilots are underway in Latin America and the US, often in collaboration with farmer co-ops and NGOs. Regen doesn’t just track carbon; it looks at full ecosystem function, making it one of the more holistic players in the space. It runs on the Cosmos SDK and offers tools for scientists to define their own credit methodologies, which can then be verified and issued on-chain.
Its emphasis on scientific rigor, open frameworks, and actual farmer payouts makes Regen one of the more grounded approaches to nature-based credits. Notably, it avoids flashy tokenomics and opts instead for slow, methodical protocol building.
Toucan Protocol
5 Blockchain Projects Tackling
Toucan was one of the first major projects to tokenize traditional carbon offsets onto the blockchain. At its peak, it helped move millions of legacy credits into DeFi systems, sparking both excitement and backlash. Critics argued that many of the credits were outdated or low quality. Toucan responded by evolving its approach, adding stricter quality filters and collaborating with registries on transparent bridges.
Its Base Carbon Tonne (BCT) and Nature Carbon Tonne (NCT) tokens were early experiments in bringing real-world carbon into Web3. Though the first wave faltered, it offered valuable lessons in integrity and interoperability. Toucan is now focused on building tech infrastructure for on-chain MRV and more selective credit tokenization.
While it’s no longer the darling of crypto-carbon, it remains one of the few projects that has actually processed and moved real credits and is still active in reshaping that pipeline.
Closing Thoughts
If climate-focused blockchain is ever going to be taken seriously, it won’t be because of whitepapers or Twitter threads. It’ll be because people built things that worked; slowly, publicly, and in hard places. These five projects aren’t flawless, and they’re not done. But they’ve moved past the idea stage and into the dirt, where climate impact actually happens. Crypto isn’t fixing the climate, but these teams show it can at least show up where it matters.
