California already has some serious laws on the books when it comes to emission standards. However, they are about to get more difficult. There have already been recent plans made to help protect the state against greenhouse gases and now they are thinking about cracking down on diesel trucks.

These trucks bring everything from clothing to groceries to toys to the state, and they take things out of the state for distribution to other areas. The health benefits of their pollution are very serious, though, and changes could be required as early as 2010 for companies that want to continue to do business within the state.

Older trucks and buses would have to be replaced because they don’t meet the same standards as the newer ones that are being created today. The trucking industry says that it cannot afford this, largely because it would be replacing a lot of trucks that it’s still paying for, but it may have little choice if it wants to continue to do business in California.
