Create an energy efficient system for carbon capture from the atmosphere and the oceans. Something that can be used at the sites for heavy emitters and also generally around the world.
Create a system to collect the captured carbon and bring it to a central site.
Fire that carbon off into interstellar space.
Use the revenue generated from fees from heavy polluters who can’t decarbonise effectively (things like steel making, glass works, air travel) to fund low carbon energy projects and storage/distribution systems for developing nations like in sub-saharan Africa and SE Asia.
My infinite money has built a space elevator to eliminate the need for rocket launches.
