Why? Then you would have 1 experimental solar plane that uses 0 fossil fuels anywhere it the supply chain.

It's not necessary to make everything use 100% renewable but rather solve some big problems that'll make a difference in reducing green house gases. Solving only 1% of a problem by reducing it to 0 means global disaster.

Yeah, you'd do far better by trying to improve the fuel efficiency for super freighters by half a percent, or less.

oh yeah if they would already enforce current regulations on emissions of these big ship (freighters, cruise, all of them) in international waters. Now they only have to be efficient, low emission near ports for example.

Ships must abide by flag country laws in international waters. There are treaties that cover most states. Compliance is an issue now though to say the least.

I was merely asking the question if that would/could be the next goal for them. Not so much wondering about a why. Or if it would even be something we should want.
