California State and federal EPA environmental regulations are all unnecessary and harmful. The massive, wasteful, expensive, totalitarian, sadistic and incompetent EPA bureaucracy can be abolished and the environment made cleaner and safer. All that is required to efficiently limit environmental pollution and risks to any desired levels are these two measures:
1. The government implements pollution monitoring and sells tradable pollution licenses for individual pollutants in specified quantities. It buys back licenses to reduce emissions. It sells more credits to increase emissions.
2. The government monetizes risk by mandating bonding, requiring that any enterprise which risks accidental environmental damage hold a bond at the value of the maximum potential damage. (Offshore drilling is a good example.) This prevents companies from causing damage which they can not afford to pay for. The cap also limits the feeding frenzy among lawyers after an accident. To reduce risk exposure the government mandates more expensive bonds. To decrease risk exposure the government mandates less expensive bonds. Let insurers price and sell bonds to those business which are required to buy them. Obviously, the actual price of the bond to the purchaser from the insurer will typically be less than the nominal value of the bond because the price will be the nominal value of the bond multiplied by a risk factor usually less than 1.
Those two measures in combination reduce pollution and accident risks to any desired level with high efficiency and they do so equitably. Externalities are bad. Internalize externalities by compelling polluters to pay for the costs of polluting and the risk-takers to safeguard against risk.
That system allows state and local preferences for pollution levels and corporate favors to combine easily and transparently with national standards. Suppose that system was actually in place in California and Tesla was lured in with either subsidies or by slackening environmental regulations. Well, under that system, it would be done by giving/subsidizing/purchasing Tesla pollution licenses and adjusting the bond requirements or subsidizing a bond. Those actions would have assigned monetary values and identifiable and quantifiable changes to the level of pollution and risk. So we would know exactly what doing favors for Tesla costs the environment in increased pollution and risk and what it costs the taxpayer in dollars.
