Sustainability has become an increasingly important focus of many crypto projects in an attempt to repair some of the reputational damage done by Bitcoin’s massive energy use. These cryptos employ eco-friendly technologies to lower their energy requirements, enabling them to reduce (or remove) their carbon footprint. 

This guide takes an in-depth look at the most sustainable cryptocurrency projects on the market, diving into how they help positively affect the environment, before exploring some of the reasons why sustainable cryptos are so important. 

The Most Sustainable Cryptocurrency Projects in 2022 – Top 10 List

Many of the most energy-efficient cryptocurrency projects ensure sustainability is high on their list of priorities, helping them appeal to a broader audience of potential investors. Listed below are ten of these projects, each of which will be reviewed thoroughly in the following section: 

  1. Chia (XCH)The Most Sustainable Cryptocurrency in 2022
  2. Ethereum (ETH)Best Sustainable Cryptocurrency for dApp Developers
  3. Tezos (XTZ)The Most Sustainable Crypto in the Blockchain Niche
  4. Polygon (MATIC) – Sustainable Scaling Solution for the Ethereum Blockchain
  5. Avalanche (AVAX) – Highly-Scalable Blockchain with Low Energy Requirements
  6. Algorand (ALGO) – Environmentally-Friendly Blockchain With Impressive Sustainability Practices
  7. Ripple (XRP) – Leading Sustainable Energy Crypto in the Payments Sector
  8. TRON (TRON) – Low-Energy Network Using Delegated Proof-of-Stake (DPoS) Consensus Protocol
  9. Stellar (XLM) – Sustainable Payments Network With CO2 Removal Pledge
  10. Cardano (ADA) – Popular Blockchain with Strong Sustainability Mission

A Detailed Look at the Most Sustainable Cryptos to Invest In

Those looking for the crypto with the most upside will likely gravitate towards sustainable cryptos, as these projects are designed with longevity in mind. To that end, most of these projects use cutting-edge technology to ensure minimal electricity requirements whilst offering valuable use cases. 

With that in mind, let’s dive in and explore the most sustainable crypto projects in more detail.

1. Chia (XCH) – The Most Sustainable Cryptocurrency in 2022

Our pick for the most sustainable crypto this year is Chia. As well as being one of the best cryptos to buy right now, Chia is a blockchain network focusing on making a positive environmental impact, evidenced by its branding and marketing. The primary way that Chia makes this impact is through its drastically reduced energy requirements, resulting from its unique ‘Proof-of-Space-and-Time’ consensus protocol.

This makes Chia different from the best proof-of-stake coins – and arguably even more energy-efficient. With Chia’s protocol, blocks are validated through network participants ‘plotting’ space on unused hard drives. Not only does this reduce electronic waste, but it also means the Chia network can operate with minimal electricity.

To put this into perspective, Chia uses just 0.19 TWh of electricity per year – around 0.16% of Bitcoin’s annual energy consumption. Chia’s team has even constructed a well-researched ‘Green Paper’, explaining in detail how this process works. As such, Chia is undoubtedly a sustainable crypto cryptocurrency with a bright future ahead.

2. Ethereum (ETH) – Best Sustainable Cryptocurrency for dApp Developers

Ethereum needs no introduction, as the network has surged into the limelight over the past few years due to its smart contract functionality. This functionality has made the Ethereum network the go-to for most decentralized application (dApp) developers, enabling the metaverse, NFT, and decentralized finance (DeFi) niches to prosper. 

At the time of writing, the ‘Ethereum merge’ has just occurred, which saw the network transition to a Proof-of-Stake (PoS) consensus protocol. This is a sustainable crypto mining alternative, as it validates transactions through staking, which requires no advanced hardware. As such, Ethereum is now far more energy-efficient than before.

As noted on Ethereum’s blog, the network will now consume around 99.95% less energy than when it used a Proof-of-Work (PoW) consensus mechanism. In turn, Ethereum now describes itself as a low-carbon platform, making it more appealing to eco-conscious developers. The move to a PoS consensus even makes the network harder to attack, highlighting the comprehensive benefits of ‘the Merge’.

3. Tezos (XTZ) – The Most Sustainable Crypto in the Blockchain Niche

Those looking for a sustainable cryptocurrency alternative to Ethereum may wish to consider Tezos. Like Ethereum, Tezos is an open-source blockchain with smart contract capabilities. However, Tezos differentiates itself by using a ‘liquid PoS’ protocol, designed to be as sustainable as possible. 

This protocol works similarly to a regular PoS protocol yet makes the validation process more accessible. Network participants can become ‘bakers’ or ‘delegators’ depending on how many XTZ tokens they hold. Through this approach, the Tezos network uses just 2.5g of CO2 equivalent per transaction.

According to Tezos’ website, the network has an average energy footprint of just 17 global citizens – with many reports stating that this is the most sustainable crypto in the blockchain sector. What’s more, Tezos has even partnered with PricewaterhouseCoopers (PwC) to accurately measure the network’s energy use and make the data publicly viewable.

4. Polygon (MATIC) – Sustainable Scaling Solution for the Ethereum Blockchain

Polygon has emerged as one of the most searched crypto projects following ‘the Merge’ since it acts as a scaling solution for Ethereum. With Ethereum in the process of becoming more scalable, there was concern that the Polygon network would no longer be needed. However, Polygon has carved out a unique position in the market, helping increase its lifespan.

Ethereum’s scalability is set to rocket in 2023 when the network implements a ‘sharding’ technique. Yet even after this technique is implemented, the Ethereum network will still not be able to handle as many transactions as Polygon can. To put this into perspective, Polygon can facilitate around 7,000 transactions per second (TPS), whilst Ethereum can only handle about 20.

Polygon is also an environmentally sustainable cryptocurrency since it has a lower carbon footprint than Microsoft and Deloitte. What’s more, Polygon’s team has pledged to go carbon-negative in 2022 through the regular purchase of carbon offsets. The team has even donated $20 million to various climate change projects to boost the network’s positive impact.

5. Avalanche (AVAX) – Highly-Scalable Blockchain with Low Energy Requirements

Avalanche has long been touted as one of the cryptos with the most potential due to its innovative multi-chain approach. Instead of using one chain, as Ethereum and Solana do, Avalanche uses three – allowing the network to dedicate specific tasks to certain chains.

This dramatically increases scalability, with the Avalanche network capable of handling 4,500 TPS. Furthermore, the network employs a variation of PoS called the ‘Avalanche Consensus’, designed to make Avalanche a sustainable energy crypto.

A report from the Crypto Carbon Ratings Institute (CCRI) shed light on Avalanche’s energy consumption, highlighting that the network only consumes around 489,311 kWh of electricity per year. This is less than ‘green’ blockchains like Cardano, Solana, and Algorand, highlighting Avalanche’s energy efficiency.

6. Algorand (ALGO) – Environmentally-Friendly Blockchain With Impressive Sustainability Practices

Algorand is a blockchain project founded by the leading cryptographer Silvio Micali, who won the prestigious Turing Award back in 2012. Many believe Algorand is one of the best long-term crypto projects due to Micali’s stewardship, with the network capable of handling a higher number of TPS than Ethereum whilst being more accessible. 

Moreover, Algorand has never suffered any downtime and supports various programming languages, meaning that dApp developers can construct their creations without having to learn another methodology. Many sustainability-focused projects are also hosted on Algorand’s network, including ClimateTrade and Watr.

Through Algorand’s ‘Pure Proof-of-Stake’ consensus protocol, the development team has stated that the network is now…
