No, but you could do enough of it in secret with Elon Musk resources to prove that it's both planetarily viable and doesn't cause catastrophes by existing and then lend your political weight to having it scaled up globally. By the time the public heard about it, it would already be a done deal.

I think you could prove it out at a scale that people could measure on planetary CO2 sensors for a couple dozen billion dollars, then take that data to a sitting POTUS you're friendly with and work out a multi-trillion dollar commercialization plan, using the USA's global bullying power to immediately establish a global monopoly.

A particularly cynical view would be this CEO buying global laws that dictate carbon neutrality while simultaneously also making it impossible to achieve without his CCS. Then merely canceling a sales contract topples a regime and you've arrived a global corporatocracy.
