Marine shipping is so cheap that even with a 15-20% price increase you probably won't see in the CPI. Air freight demand is far more elastic.
Although the price increase framework is useful, some prices are more important than others. So although I dislike targeted policies there is some inventive to target carbon taxes on some sectors over others.
# The Maritime Revolution: How Carbon Pricing Will Transform Global Shipping
The International Maritime Organization has established new rules for decarbonizing shipping. By 2040, the industry must reduce emissions by 70 percent or face a carbon tax between $100 to $380 per tonne.
Michael Bernard maintains considerable optimism about electrification's potential to significantly reduce emissions, particularly when combined with bioethanol solutions.
