One of the biggest end-user of CO2 is the fossil fuel industry, blowing CO2 into well to extract more fossil fuel .... Will OP make sure their product is not used to extract more fossil fuels?
When the CO2 gets left behind in a reservoir, it's still a net positive for the environment. There are even oil companies aiming to produce 'carbon-neutral oil' [0].
