There is nothing about the climate change narrative that is anti corporation.

Then why are so many corporations so desperately trying to spin climate change as fake?

Any regulations will stop competition from springing up because startup costs will be too high, while established powers will pass the costs to consumers.

Very true... except when its not.

Concrete producers have a captive audience, and very few alternatives, so they can just raise prices. Up to a point, then consumers will just cut their usage of concrete. Demand for concrete is not infinitely inelastic: eventually people will just make do with less, or find alternative building materials.

Coal has to compete with cheaper, more efficient sources of energy, and they cannot put prices up without pricing themselves out of the market. Coal is already on its way out.

Companies that can save fuel can pass those savings onto the customers and out-compete companies that don't save fuel, or make a higher profit. Either way, they have an incentive to cut their costs.

Consumers can choose more energy-efficient products which cost less, or other alternatives. If flying overseas on holiday costs more, they can have their holiday locally and support local businesses.

Free market economists like to have it both ways: they claim that any government tax or regulation will cut corporate profit, or cause consumers to use less of the product being taxed -- except for CO2, where they claim that government taxes and regulations will have "no effect" on both profit and usage. Just like magic, hey?

Personally, I believe that if governments would just transfer the hundreds of billions of dollars in fossil fuel subsidies and protectionism (including military force to defend access to oil and gas) to greener, renewable energy, we would solve climate change in a decade.
