This research looks at how Blockchain might fix problems in carbon credit markets when it comes to being open, stopping fraud, and tracking things as they happen. It takes a deep dive into current carbon credit systems to find big issues like counting things twice, not having the same rules for everyone, and slow ways of doing business. The study then checks if blockchain's spread-out features can help. Real-life examples show that blockchain can cut business costs by up to 30% by using smart contracts. It also helps more people join in by checking things right away and letting everyone see how credits move. These changes make carbon credit systems more trustworthy and help countries work together better. But there are still problems, like making blockchain work for more people, the fact that it uses a lot of energy and that different industries don't all follow the same rules. To fix these, we need to study blockchains that use less energy and make rules that work worldwide. Even with these problems, blockchain can help by making paperwork easier, cutting costs, and holding people responsible. This lets smaller groups join in and makes the market work better. The study points out that it's new and important to mix blockchain with things like the Internet of Things and AI to track emissions and check credits better in real time.
