This article suggests a plan to bring together systems that control greenhouse gas (GHG) and air pollutant emissions. It talks about ways to get companies to join and follow rules to lower GHG emissions. One method involves encouraging participation by offering money incentives, but it has some challenges like needing lots of money upfront and agreeing on certain goals with the government. Another method already in place is to make companies stick to a set limit on emissions, and this could work well with the air pollution system. The government may want to use rewards to get companies on board, as joining now can help them learn and earn benefits later. Even though the exact timing for these emission cuts and trading systems may not be clear, they will be needed in the future. So, it's important for the government to prepare and keep an eye on how these systems work together to help industries adapt and improve.
