Depends what is meant by green. Acetone is decent for health and safety (flammability notwithstanding) but is produced from petrochemicals and tied to the production of phenol (petroleum -> benzene and propane (or natural gas -> propane), propane -> propylene, benzene + propylene -> cumene, cumene + O2 -> phenol + acetone). Not much chlorophyll involved. Also has somewhere between a moderate to obscene CO2 burden depending on how you draw that box in and around the oil industry, but so do most commodity chemicals.
I for one haven’t used heavy metal catalysts in a year
Maybe not directly, but a lot of commodity chemicals rely on some truly vile metal mixtures for catalysis :)
Acetone is rather green (7 in GSK solvent guide), but I for one haven’t used heavy metal catalysts in a year, and more if you don’t count palladium
