This is what has to happen eventually. All emissions, carbon and otherwise must be taxed at a rate that it takes to remove those emissions. If your business is making a mess, then the government needs to make it your business to clean up after yourself. This isn't just gaseous emissions either. But the liquid emissions that come from pumping waste water in to rivers and oceans, the solid emissions of pesticides and fertilisers that run off fields in to rivers because of rainfall. If your process damages the environment in any way shape or form then the governments job is to intervene and make it your job to clean up after yourself. Not just when things are catastrophically failing either. But from get go with no limitation on liability.
