The rising levels of carbon dioxide in the Earth's atmosphere are a cause for global concern due to its contribution to global warming. As a result, a universal carbon market has emerged, offering opportunities for trading carbon credits both within and beyond regulated areas. Blockchain technology is characterized by a chain of blocks linked together, providing integrity and security in a variety of applications. Utilizing blockchain for trading carbon credits would enhance security, transparency, and efficiency. Consequently, this examination examines how blockchain innovation would influence the fossil fuel by product exchanging and assist the members with taking on a drawn-out arrangement in discharge decrease.
