Coming right up fast, across the world, unless there is mass public pushback, are carbon passports for international travellers, and perhaps after that, carbon passports to even travel between states. Various climate change alarmist advocates have championed the idea that "personal carbon allowances" in the form of carbon passports would vastly reduce the number of international flights that people could make, thus reducing their carbon footprint from air travel.
While the privacy and social control aspects of such proposals have been given a lively internet discuss, the first issue of concern here is that such measures will severely impact upon the world tourism industry. Tourism now is heavily committed to people being able to make use of air plane travel; while sea is possible with luxury cruises, most people simply want to visit a country like say Australia, see the sights, then go home back to work. There is no time for long transport ventures. Thus, along with the winding down of agriculture, the closing of farms, as seen with the Netherlands, the carbon passport will virtually guarantee the end of tourism, creating even more unemployment. But, that is the plan.
