There are other hurdles to get to "zero emissions"
The elimination of vehicle emissions, whether talking about airplanes or automobiles, is great but only addresses part of the problem. Natural gas vehicles have zero emissions, but fracking for the gas can create massive methane emissions (not to mention water contamination) on top of the standard emissions from the drilling operations. Electric cars and this solar hybrid plane have zero emissions, but power from gas, coal, and other fossil fuels creates a constant flow of greenhouse gases into the atmosphere. Even nuclear (fission) has emissions from the mining of uranium. Don't get me wrong, we're making progress, but we should do everything we can to avoid mistakes along the way.
