Introduction to Green Blockchain
Green Blockchain has experienced quick growth and created adoption across various sectors, and it has reduced carbon footprint. Earlier, there was a major issue with investment in blockchain about considerable energy consumption, which negatively affects the environment. The main issue was due to carbon emission, with the excessive usage of energy (Mahmud, Kamal, & Reza, 2025). It utilizes less energy with carbon dioxide than blockchain. The green blockchain refers to minimization of environmental impact and enhancing sustainable practices. There were systems such as proof of work, which is known as Bitcoin, which has high carbon emissions.
Issue: Energy consumption in Blockchain
Blockchain technology, especially as it is widely adopted in the form of cryptocurrency like Bitcoin. Bitcoin is majorly known for its energy usage. Basically, this is a primary result of the proof of work algorithm, (Khan, Ullah, Liu, & Kashif, 2024). which demanded high computational resources to enhance the transactions and ensure security in the network. It uses a high consumption of electricity each year with Bitcoin. It resulted in many disadvantages. The high energy demand of these operations arises from the requirement of minors to solve the mathematical problems using powerful computational techniques and hardware. With this process, this assists in securing the blockchain by making it costly and also challenging for the transactions to happen. It also leads to substantial electricity consumption and more carbon emission. This directly affects the climatic change worldwide and the environmental impact due to the high energy consumption.

Benefits of Green Blockchain
Decrease carbon footprint
One of the major advantages of green blockchain is a decrease of carbon footprint in the operation of blockchain. As blockchain is a proof-of-work based system, this has revealed issues regarding high energy consumption. There is an alternative model known as proof of stake, choose for the blockchain. It eliminates the energy consumption and enhances the operations (Solutions, 2024). These energy efficient mechanisms enhance sustainable use of resources and secure the network of blockchain. Also, it validates each token. This eliminates the need for a huge amount of energy to validate the transactions. Moreover, this leads to elimination of electricity consumption and carbon emissions.
Enhanced energy consumption
The Blockchain technology, particularly increases the efficiency and transparency of the distribution of energy systems. It permits both flexible and reliable electricity distribution. It is because of its decentralized management of grid energy (Agarwal, Mishra, & Pal, 2024). There is also involvement of peer-to-peer trading energy, which eliminates the need for centralized management, and it eliminates the cost for consumers. For example, there is usage of blockchain in Power Ledger to enhance energy trading between users and increase efficient usage of resources. In real time, this assists in supply and demand with the help of automation of transactions and high energy distribution. The smart contracts make sure that transactions are automated with specific conditions in the process of distribution.
Promoting adoption of renewable energy
Especially, the Blockchain plays a key role in accelerating the adoption of renewable energy by making use of peer-to-peer energy systems. These platforms allow the consumers to exchange the renewable energies such as wind power and solar power without any intervention of intermediaries. This not only benefits in lowering the transaction cost but also enhances competitiveness in the energy market with the use of renewable energy sources. These energy sources required a high amount of hydroelectric power. So, to avoid this, the use of fossil fuels enhances the energy source and reduces the carbon emission in the environment.

Application of Green blockchain
Supply chain management
Basically, the green blockchain helps in providing transparency and accountability. In this case, this keeps a track of each process of production and transportation that monitors the carbon footprint. Moreover, it ensures sustainable practices are followed with eco-friendly materials and reducing the transportation emissions.
Industries
It focuses on mining, agriculture, and forest to reduce the environment impact. The sustainable practices are followed, such as the usage of practices to reduce carbon footprints. In addition, the blockchain initiates to track each and every process to enhance the sustainability.
Sustainability and food security
Generally, green blockchain supports tracking the products from the sources, lowers the emission of farming with organic practices. This also helps in waste management and enhances the product supply with face practices. Moreover, it participates in the reuse of materials and recycling of materials with minimizing the wastage.
Future considerations
The future of green blockchain is enhanced and transformative. The adoption does not only meet the organization’s needs but also increases the eco-conscious market. There will be a rise in demand for enhancements of green blockchain with more scalable solutions. Advancements in blockchain mechanisms in the models like proof of stake continue to increase. The innovative techniques in energy consumption and scalability of green blockchains. Furthermore, the green blockchain increases interoperability and maintains seamless communication in the transportation (Chakravartty, 2025). There are standardized methodologies to ensure accountability. There is also a plan for integrating with eco-friendly technologies and creating an efficient energy market. As the world is moving towards low carbon emission, the green blockchain will play an essential role in the development of industries and investments will be made into sustainable projects.
Conclusion
The Green Blockchain represents a great shift towards sustainable management and a responsible decentralized system. With the use of efficient algorithms and initiatives of green technology, eliminate the concerns regarding environmental factors. The blockchain technology continues to grow in the sustainable field and explores various technological advancements in the future. The integration of blockchain with renewable energy system holds a promising solution to a sustainable environment. Moreover, it handles the growing complexity and ensures sustainable development. As blockchain offers a decentralized, transparent platform, this enhances trust in the renewable energy market. However, with the increase of green blockchain solutions, there is a great impact towards environmental footprint and contribution towards global climatic change.
