Fuels to transition the global legacy fleet

The EV bandwagon has obscured potential solutions for decarbonizing the enormous global ICE legacy fleet.

Put the promise of mass vehicle electrification and its myriad challenges aside for a moment, and consider: What if most IC-engine vehicle owners don't switch to EVs as the industry and regulators hope they will?

And how long will it take to alter the existing global vehicle parc, estimated at more than one billion mostly ICE-powered vehicles, to the extent its greenhouse-gas emissions are insignificant in the crusade to achieve net-zero (and thwart global warming) by 2050?
