HD Diesel emissions for 2024 ( pick-ups to follow?)

For those trying to point the finger at Obama for diesel regulations. But the 2007 and 2011 requirements were put in long before Obama was in office. Trump won't help with diesel regulations, monitoring regulations is done at the state level. And myself, I appreciate having cleaner air. Even if there are some additional emissions requirements. It wasn't that long ago that diesels smoked a ton stock.
