I think there is an easy way kill this DAC concept. Have a tax on fossil fuels that in 10 years time ramps up to the cost of capturing CO2. The government will use this tax to buy services of companies that do this. Big companies can also capture CO2 themselves and pay less tax (or get a refund) if they can prove they did so.

This way, you can bet on DAC becoming cheap, or you can invest in renewables.

> easy way ... tax on fossil fuels

I'm not sure those two phrases belong in the same paragraph, for the same exact reasons stated by the gp.

The Paris Climate models (1.5 degrees and 2 degrees) assumes that we are going have to remove a lot of carbon. This is not an either or - we need to both move to a carbon-free economy and remove carbon

> we need to both move to a carbon-free economy and remove carbon

We need to move to a net negative carbon economy (not carbon free, net negative), or find ways to reduce input heat (reflecting sunlight basically).
