As nice as it would be, a not insignificant amount of coal being transported is destined to steel production. Steel is iron + carbon, and the easiest source of carbon is coal. Steel is pretty important, so that's not going away anytime soon. I wonder if carbon capture could make a product that could be used to replace coal here though, and fairly effectively sequester the carbon in an actually useful form?
What biomass grows the fastest without being waterlogged - I imagine bamboo or sugarcane or something
Grow that, and burn it to make carbon neutral steel; bonus points if you do it in a highrise/underground farm but frankly some medium term reversible environmental damage is preferable to killing off way more with climate change

There are efforts to develop green steel, it'll be more expensive than coal, but coal is only so cheap because of the huge amount mined for fuel
