On this 37, they're mixing their metaphors. They're telling you the new fleet is very different on greenhouse gases. It's not. It hasn't improved marginally in the last 15 or 16 years. The number they're giving you is about the improvement in the smog emissions, but their climate change emissions aren't that much different. If you had the last seven years...it's about the same. The standard hasn't changed since 1990, and the fleet hasn't improved significantly since then.
