Slow down - and reduce GHG emissions

I am often looking to get where I'm going as fast as possible but I am learning to give myself enough time to slow down.  Without the push to get there fast, you can enjoy the ride and the cost savings.  Reducing highway speed from 120 to 110 km/h can deliver fuel savings of 12–18 % for most cars.  Maintaining consistent speed and reducing quick starts and stops increases savings. On a recent road trip, I noticed the fuel consumption drop from 9 l/100km to 7.5 l/100km just by reducing speed.
