5 Green Crypto Projects September 2025

Jakarta, Pintu News – The cryptocurrency world is growing not only in terms of technology and adoption, but also in terms of environmental sustainability.

Amid the spotlight on the high energy consumption of blockchains like Bitcoin (BTC), a number of crypto projects are starting to emerge as eco-friendly alternatives with a lower carbon footprint.

What cryptos are there? Check out the full information in this article!

Cardano (ADA): Pioneer of Efficient Proof-of-Stake

Cardano (ADA) is one of the pioneers of implementing proof-of-stake (PoS) which is more energy efficient than proof-of-work. Through this consensus model, Cardano is able to significantly cut the carbon footprint without compromising network security.

Furthermore, Cardano launched the Cardano Carbon Footprint initiative to establish a transparent greenhouse gas emissions accounting standard. The program is supported by Catalyst Fund 7 and involves experts, communities, and organizations such as My Carbon Zero to conduct verification. With this approach, Cardano is not only heading towards being carbon neutral, but also has the ambition to become a blockchain with a positive contribution to the climate.

VeChain (VET): Efficient Blockchain with Proof-of-Authority

VeChain (VET) is known as one of the green cryptos with low energy consumption. The VeChainThor network uses proof-of-authority (PoA) consensus which is more efficient than PoS. The system is able to handle transactions faster, at a low cost, while maintaining energy efficiency.

The advantages of VeChain are evident from its adoption in the real world. Major companies such as Walmart China, Bayer, and certification body DNV have used VeChain for supply chain and sustainability solutions. No wonder VET is now among the top 50 cryptocurrencies by market capitalization.

Algorand (ALGO): Carbon-Negative Blockchain

Algorand (ALGO) comes as a blockchain that is claimed to be carbon-negative with high performance. Algorand uses Pure Proof-of-Stake (PPoS) consensus capable of supporting thousands of transactions per second with very low energy consumption.

According to the Crypto Carbon Ratings Institute, Algorand’s annual electricity consumption is 118,600 times lower than Bitcoin and 3.2 times lower than Ethereum (ETH). In addition to energy efficiency, Algorand also supports the dApps ecosystem, including DeFi, gaming, and tokenization of real-world assets, making it one of the most promising eco crypto.

Hedera (HBAR): Certified Eco Ledger

Hedera (HBAR) occupies a privileged position as a public blockchain with carbon-negative certification. The project regularly purchases carbon offset credits every quarter based on assessments from third parties like Terrapass. In this way, the emissions produced can be offset even more, making Hedera one of the most environmentally friendly blockchains.

In addition, the Hedera Foundation actively funds sustainability projects, carbon tokenization, and integration with DeFi and AI technologies. This approach reinforces Hedera’s reputation as a crypto that is not only energy efficient through proof-of-stake, but also proactively supports global green projects.

Polka Dot (DOT): Eco-Friendly Layer Zero

Polkadot (DOT) is known as the “Layer Zero blockchain” because it underpins many layer one blockchains above it. The network uses Nominated Proof-of-Stake (NPoS) consensus which is energy efficient while maintaining decentralization.

Polkadot claims to have one of the lowest carbon footprints in the blockchain industry. Its adoption is also expanding, including a collaboration with FIFA in June 2025 to launch the NFT-based FIFA Rivals game. This makes Polkadot one of the eco-friendly blockchain choices in 2025.

Conclusion

Sustainability is now one of the most important factors in the cryptocurrency ecosystem. Projects like Cardano (ADA), VeChain (VET), Algorand (ALGO), Hedera (HBAR), and Polkadot (DOT) prove that blockchain innovation can go hand in hand with environmental responsibility.

With energy-friendly technologies and widespread real-world adoption, green crypto is not only promising in terms of sustainability, but also has long-term investment prospects.
