That is grossly misleading because one of those things is very much not like the others.
Ships measure fuel in tons per hour. It only takes a few hundred transport ships to put out as much pollution as every car on the planet and there are hundreds of thousands of them with their collective output dwarfing cars and trucks combined by several orders of magnitude.
If we really wanted to cut transportation pollution fast, we'd internationally mandate turbosails on all transport ships as current models cut fuel consumption by 25% or more.
Stepping aside from ships, big rigs are the overwhelmingly biggest NOx contributors (even beating out industrial and power plants).
Stepping back though, transportation in ALL its forms still only contributes around 1/4 of the US greenhouse emissions.
- akamaka 6y agoWhat’s misleading about it? We are talking about the health effects on people living in cities in California, not about cargo ships burning dirty fuel in the middle of the ocean or general global greenhouse gas emissions. It is a true statement that vehicle traffic is a major source of harmful pollution in US cities.
