enabling a sustainable world built by blockchain.
Cleanblocks offers guidance towards a sustainable blockchain industry and how to use blockchain to accelerate the sustainable transition.
We have created the largest green rating with 100+ of cryptocurrencies rated from True Green to Brown.
Our advisory offer services for the blockchain industry looking to achieve carbon neutrality, ESG performance or MICA compliance. Advice for you outside of blockchain to understand how sustainable different blockchain assets are, or tailored solutions to find the right blockchain solution for achieving transparency and traceability.

THE CLEANBLOCKS RATING
The rating provides most importantly insight into the environmental impact of cryptocurrencies by classifying its energy usage and carbon footprint. A True Green rating by Cleanblocks means as a result that it is carbon neutral. See a selection below and find the full list at our partner Cryptowisser.
blockchain for the people
Blockchain is designed for the people and created with a decentralized world in mind which creates freedom of money, secure your rights, assets, and agreements, and reduces the risk of fraud.
Blockchain has the potential to bank the unbankable, allows fast, reliable, and low-cost transactions around the globe and can be an option to a local inflationary currency. Smart contracts creates transparency and traceability between users without the middleman. Smart contracts can be used for example in creating immutable certificates, business contracts and legal documents. To achieve a sustainable transformation, smart contracts can create transparency in purchase and sale of clean energy, carbon credits, a clean supply chain and ESG investments.
blockchain for the planet
So what is the story of the environmental impact from crypto? Blockchain uses energy through mining or by running nodes and the energy used creates emissions when generated. It is similar as a data center. The energy efficiency of a blockchain depends on its consensus algorithm. The algorithm “Proof of Work” that Bitcoin uses, consumes roughly 1000x more energy per transaction than a “Proof of Stake” algorithm that Ethereum or Polygon uses. Energy efficiency matters, but the size of the actual emissions created depends on how clean the energy is in the grid. As we exit fossil fuels to achieve a clean global energy transition, we need to create a dramatic increase of clean energy. Energy efficient blockchains, (see our rating above) emit similar as sending an email and can assist in a global sustainable transformation. What about Bitcoin? It brings value through social and economic sustainability but performs worse on environmental. However, Cleanblocks considers it green, if it invests in the creation of new renewable energy that exceeds its own use or reduce overall emissions by harvesting energy from stranded assets. Other environmental parameters such as recycling of electronic waste and avoidance of conflict materials should also be considered.
