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. C+Charge (CCHG) - Most Sustainable Cryptocurrency in 2023 Offering EV Drivers Incentives

C+Charge is our most sustainable cryptocurrency project as it seeks to drive electric vehicle (EV) ownership by incentivizing drivers while they recharge.

The project, which has just launched its presale, will do that by offering carbon credits as a reward for drivers who recharge while using the C+Charge mobile app.

Carbon credits are permits that allow a holder to offset their carbon footprint by funding projects that are good for the environment, with one carbon credit equal to one ton of CO2.

Previously the domain of big businesses, C+Charge also seeks to democratize carbon credit ownership and allow individuals to hold them. 

Tesla, for example, is able to generate billions of dollars by selling carbon credits to other companies, allowing them to offset their own carbon footprint that is built up in the manufacturing or logistics process.

C+Charge has partnered with Flowcarbon to allow its users to earn Goodness Nature Tokens (GNT) which are 1:1 backed by verified carbon regeneration projects. Flowcarbon enjoyed an incredible seed funding round in the middle of 2022, with major venture capital firms such as Invesco, Samsung Next and a16z investing $70 million into the project.

As well as offering rewards to incentivize EV drivers, the C+Charge mobile app also has other features that will help eliminate inefficiency and inconvenience - two major roadblocks to more drivers moving to EVs.

EV charging stations currently offer huge variety in price, can be difficult to locate and are often either in use or broken when drivers arrive. The C+Charge app will offer uniform pricing, while users can also find their nearest charging point using a geolocator and check diagnostic data to determine waiting times and whether a charging station is functional.

The project, which has a doxxed and KYC-verified team, has also already partnered with Perfect Solutions Turkey, which means it now operates 20% of charging stations in the country.

CCHG tokens have just launched in the first stage of the presale and are now available for $0.013 - by the fourth and final stage, they will cost $0.0235, an increase of 80%.

A total of 40% of the 1 billion max supply of CCHG tokens are available during the presale, with no vesting period and a hard cap of $6.6 million.

For more information on C+Charge, read through the whitepaper or join the Telegram group.

2. IMPT (IMPT) – Unique Carbon Offsetting Protocol now listed on Exchanges

Another top pick for the most sustainable cryptocurrencies is the carbon credits ecosystem IMPT

IMPT is now listed on numerous exchanges after enjoying one of the best crypto presales of 2022, where it raised more than $20 million, and IMPT tokens are expected to surge in 2023 when market conditions improve, given the huge interest in the platform and its potential.

IMPT leverages the power of the Ethereum blockchain - which is now one of the most energy-efficient blockchains after the Merge - to provide a platform where individuals and companies can buy, sell, earn, and trade carbon credits.

As mentioned above, carbon credits are a permit that allows the holder to emit a certain amount of CO2. With IMPT, carbon credits can be traded on the secondary market and have values dictated by the laws of supply and demand. Alternatively, carbon credits can also be retired, which takes them out of circulation and effectively 'removes' CO2 from the atmosphere.

According to data from ClimateTrade, more than 362 million carbon credits were traded on the voluntary market in 2021 – a 92% increase from 2020. However, the market still struggles with a lack of transparency, and scams are rife, which makes carbon credits less accessible to individuals.

IMPT looks to solve all this, as the platform allows individuals to acquire carbon credits through their normal shopping activities. As noted in IMPT’s whitepaper, this is achieved through partnerships with over 10,000 leading brands, including Amazon, Microsoft, and LEGO.

When a member of the IMPT ecosystem shops with one of these brands, a percentage of the revenue will be dedicated to sustainability projects. Through this process, shoppers will receive $IMPT tokens once their purchase is complete. Once enough of these tokens are acquired, they can be exchanged into carbon credits on IMPT's marketplace.

The unique thing about IMPT's approach is that each carbon credit is structured as an NFT. Not only does this mean that credits cannot be tampered with, but they can be easily traded between individuals and companies.

For example, if an IMPT user has acquired enough points through shopping to acquire a carbon credit, they can hold that credit and wait for the price to rise. Assuming the value of the credit increases, the user can then sell the credit to another user – thereby generating an income stream that stems from their everyday shopping activities.

Alternatively, users can also ‘retire’ their carbon credits if they wish to make a lasting impact on the environment. Users who take this approach will be rewarded with a unique digital artwork NFT, shared with the creator who designed it. Again, these NFTs can be traded on IMPT’s marketplace, providing another way to generate income. 

This exciting sustainable crypto platform has now been listed much sooner than first anticipated with the doxxed and KYC-verified developers spotting a gap in the market and realizing the huge potential of the protocol.

Already listed on Uniswap and LBank, BitMart and Changelly Pro will list the token in the coming weeks with more exchanges expected to be announced and the platform expected to go live at some point in the first half of 2023.

All told, IMPT’s current price is a limited-time opportunity to obtain cut-price tokens, which could put investors in line for solid returns in the future as the ecosystem expands. Those looking to learn more about IMPT can do so by joining the official Telegram group.

3. Chia (XCH) – Popular Sustainable Cryptocurrency in 2022

Another 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 the greenest cryptocurrency with a bright future ahead.

4. 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. 

The Ethereum merge took place in September 2022, seeing the network transition to a Proof-of-Stake (PoS) consensus protocol and not only making the platform faster and more usable for dApp builders, but making it much more energy efficient.

This is a sustainable crypto-mining alternative, as it validates transactions through staking, which requires no advanced hardware.

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'.

5. 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.

6. 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.

7. 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.

8. 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 carbon-neutral – with the intention to become carbon-negative in the future. This is achieved by Algorand’s team regularly purchasing carbon offsets through the partnership with ClimateTrade, making it one of the most sustainable crypto projects on our list.

9. Ripple (XRP) – Leading Sustainable Energy Crypto in the Payments Sector

Ripple differs from many other projects on our list because it focuses solely on revolutionizing the payments sector. Using blockchain technology, the Ripple network can process digital transactions much faster (and cheaper) than traditional payment systems like SWIFT.

For context, Ripple-based transactions take just five seconds to complete, with fees that equate to a fraction of a cent. These transactions are verified through a consensus protocol rather than mining, meaning the Ripple network is both fast and energy-efficient.

According to the XRP Carbon Calculator, each transaction on the Ripple network consumes just 0.0079 kWh of electricity. This is actually less than the 0.440 kWh of electricity consumed in paper currency transactions. Finally, the Ripple network has been shown only to emit 270 metric tons of CO2 each year – exponentially less than the Bitcoin network.

10. TRON (TRON) – Low-Energy Network Using Delegated Proof-of-Stake (DPoS) Consensus Protocol

TRON emerged as one of the market’s top trending cryptos in mid-2021 when the token's price surged by over 660%. Investors found TRON attractive due to its aim of decentralizing the web – specifically focusing on the entertainment industry.

Using TRON's network, content creators can remove the middleman and have more control over their creations. Moreover, the TRON network has smart contract functionality and is compatible with the Ethereum Virtual Machine (EVM). This means developers who initially created their dApps on Ethereum can easily port them over.

In terms of sustainability, a report by the CCRI found that the TRON network consumes as much electricity annually as just 15 US households. Moreover, TRON’s electricity consumption was reportedly less than that of leading networks like Algorand, Cardano, and Solana. This is achieved through TRON’s delegated proof-of-stake (DPoS) consensus, which ensures the network is sustainable while remaining decentralized.

11. Stellar (XLM) – Sustainable Payments Network With CO2 Removal Pledge

Stellar is an environmentally sustainable cryptocurrency operating in the payments sector. Like Ripple, Stellar aims to make cross-border payments faster and cheaper than they currently are. This is achieved through the 'Stellar Consensus Protocol', which uses 'nodes' worldwide to validate transactions. 

This means network users can send money worldwide, with transactions only taking five seconds to finalize. Interestingly, Stellar's development team has also focused on sustainability, enlisting the help of PwC to help accurately assess the network’s electricity consumption and greenhouse gas emissions.

According to the Stellar Foundation, a node running Stellar’s software only consumes around 261,435 kWh of electricity per year – about the same as 22 US households. To mitigate this impact even further, Stellar’s team has also established a carbon dioxide removal commitment, pledging to pay for the removal of the network’s carbon footprint since 2015.

12. Cardano (ADA) - Popular Blockchain with Strong Sustainability Mission

Concluding our list of sustainable cryptocurrency projects is Cardano. Cardano is often listed as one of the best altcoins on the market due to its peer-reviewed approach, combined with its leadership from Ethereum co-founder Charles Hoskinson. Like Ethereum, Cardano has become a hub for dApp developers operating in various sectors.

Cardano has one of the first blockchains to popularize the PoS consensus mechanism, with the developers naming their approach ‘Ouroboros’. Like other PoS chains, Cardano's energy expenditure is low relative to the best proof-of-work coins.

Interestingly, Cardano's team has several roles dedicated solely to sustainability and publishes an in-depth sustainability report each year that details the positive impact the network is having. Cardano's team has also targeted net-zero emissions for the chain and actively pursues investments that drive them towards this goal.

What is a Sustainable Cryptocurrency?

Now that we’ve listed some of the most sustainable cryptos on the market, let’s discuss what these cryptos actually are. Most market participants define sustainable cryptocurrencies as those that actively minimize their energy requirements to reduce their carbon footprint.

Sustainable crypto cryptocurrency projects have seen a surge in demand over the past few years due to the looming threat of global warming. According to data from NASA, the planet’s temperature has risen by 1.01°C since 1880. Although it doesn't seem like much, this slight increase in temperature has led to a rapid rise in the sea level – which could have disastrous effects.

One of the major contributors to the planet’s rising temperature is CO2 emissions, which come from many sources – including electricity generation. As such, when a cryptocurrency network (e.g. Bitcoin) uses enormous amounts of energy, it directly leads to more CO2 being pumped into the atmosphere – which negatively affects the environment.

This is where sustainable cryptos come in, as these projects use technologies that minimize their electricity requirements. The most common technology used is the Proof-of-Stake (PoS) consensus mechanism, which allows networks to validate transactions without the need for energy-intensive ‘mining’. 

This sustainable crypto mining alternative has now become the ‘go-to’ for most blockchain networks, as not only does it require less energy, but it also allows network participants to generate a yield through staking. Some networks even take things one step further by putting their own spin on the PoS protocol – for example, Chia uses a ‘Proof-of-Space-and-Time’ mechanism to secure the network.

These sustainable networks look to be the future since the crypto market's growth shows no signs of slowing down. This growth will inevitably lead to more significant energy requirements, which is why energy-efficient networks are so crucial. As a result, investors will naturally gravitate away from high-energy projects in favour of ‘greener’ alternatives.

Key Reasons Why Sustainable Crypto is Important

Most new cryptocurrency projects have sustainability as one of their fundamental values, designing their technology to be as energy-efficient as possible. 

Yet why are these sustainable cryptos so important? To answer this question, presented below are four reasons why these cryptos are likely to be the future: 

Improves the Crypto Market’s Reputation

One of the main reasons that sustainable cryptocurrencies are so important is that they help improve the market's reputation. Most market participants will have seen negative press about Bitcoin's colossal energy requirements, which has harmed people's perception of crypto as a whole. 

However, as sustainable cryptos become more prevalent, these perceptions will start to change. In turn, crypto investing will become appealing to new demographics, causing more capital to flow into crypto projects and leading to further innovation.

Help Slow Down Global Warming

As noted by Climate.gov, the average combined land and ocean temperature increase per decade since 1981 has reached 0.18°C. This is more than double what it was before 1981 and highlights the need for rapid change.

Sustainable cryptos can help offer a solution, as not only do they consume lower amounts of energy, but they also make energy-intensive projects less appealing. As this trend continues, we'll likely see these projects fall by the wayside, reducing the crypto market's contribution to global warming. 

Provides Scope for High Returns

Investing in sustainable crypto can also be lucrative, as these projects often have the most extended lifespan. This is because sustainable cryptos tend to employ the latest technology to reduce their electricity consumption, helping them stay ahead of the pack.

What's more, a growing number of investors are becoming environmentally conscious, meaning these sustainable projects are even more appealing than before. As more investment flows into these projects, it'll help them expand and improve – providing scope for higher investor returns.

Helps Futureproof the Market

Finally, the rise of sustainable cryptocurrencies has undoubtedly helped the crypto market’s longevity, which was at risk when Bitcoin was the only viable option. With more projects than ever utilizing sustainable practices, the market's future looks exceedingly bright.

Furthermore, due to the market’s competitive nature, these projects will naturally continue to innovate to stay ahead of the pack. Not only will this benefit the project individually, but it'll prompt other projects to follow suit – helping boost the positive environmental impact. 

How Can Investors Find Sustainable Cryptocurrencies?

Investors looking to buy sustainable cryptocurrencies must ensure that they actually are sustainable rather than just claiming to be. To streamline this process, detailed below are some of the best approaches investors can take when identifying sustainable projects: 

Use Social Media Platforms

Social media is an excellent way for investors to uncover cryptocurrency projects with sustainable values. Most leading cryptos now have Twitter and Instagram accounts, providing regular updates on the project and its ambitions.

By scrolling a project’s Twitter or Instagram feed, it’ll become apparent whether that project has an environmental focus on not. In addition, investors can also scour various subreddits, such as r/CryptoCurrency, to look for threads dedicated to eco-friendly cryptos.

Look for Technological Innovations

Although PoS blockchains are the most common alternative to PoW chains, there are other technologies that offer a sustainable way to validate transactions. Although not discussed in this article, projects like Hedera and IOTA use unique mechanisms that enable them to be both sustainable and scalable. 

In addition, investors can also keep tabs on established projects to see if they are implementing any significant changes. A prime example of this is Ethereum's shift to a PoS consensus mechanism, which means the network is now much more sustainable. 

Keep Up with Current Affairs

Investors can also keep up with the latest crypto news articles to see which projects are gaining publicity for their sustainability efforts. The increased need for sustainable cryptos has meant that these projects are often thrust into the limelight, helping investors become aware of them.

Those looking for sustainable projects can also keep tabs on current affairs worldwide. By doing this, investors can identify environmental issues and then seek out projects that solve those issues, whether that be through decreased energy consumption or purchasing carbon offsets. 

Read the Project’s Whitepaper

Finally, investors can uncover sustainable cryptos by reading the project’s whitepaper. The whitepaper will detail the intricacies of the project’s technology, allowing investors to see whether it can really be considered sustainable. 

Additionally, investors can also analyze the project's whitepaper to see the team's future plans. If the roadmap notes goals such as net-zero emissions or carbon neutrality, then the project in question is highly likely to value sustainability.
