@dorianshadesofgray You could plant trees on every spare inch of available piece of land on the planet, and go nowhere near achieving net-zero emissions. It requires commercial aircraft without jet engines, ships powered by a yet to be discovered energy source, long-haul trucks the same, carbon-capture and storage to suck CO2 out of the atmosphere on a massive scale (a technology yet to be developed), complete changes in food systems, the elimination of farm animals, (everyone becoming a vegan), new technologies for making steel, pretty much eliminating cement the basis of the most widely used building material in the world, concrete,and on and on it goes.
The International Energy Agency recently released a report outlining what would be required. People should read it to realize just how much of a con the whole notion is.
