They plan on purchasing 160 clean diesel buses. They say the buses will have better engines and will burn cleaner fuel. But environmental groups say the buses will still pollute the air. They also say there's a shortage of better grade diesel fuel and it won't be available for a couple of years. So basically they would be burning regular diesel until that time.
Environmental groups say natural gas is the only real solution for better air quality.
There are better buses being made right now and we want to take that into consideration. But DART officials say those buses will cost more. The vehicles cost more on the front end. DART officials say they do want what's best for the environment and they feel the new diesel buses are the best alternative. Environmental groups say they're heading down a wrong way street and fear air quality will pay the price.
