Depends on what you regard as "emissions control".

Picture, if you will, a 1965 Mustang. It makes somewhere around 200 HP, gets something like 12 MPG on the freeway, and emits unbelievable amounts of pollution. Compare to a 2008 Mustang GT. It makes 300 HP, gets 27 MPG on the freeway (current EPA rating), and the exhaust is arguably cleaner than Houston or L.A. air on a bad day.

Fuel injection was, at least for a while, regarded as "emissions control equipment". And that is one of the main things that is responsible for the increase of HP, the increase of fuel economy, and the decrease of emissions...
