Okay done. Now that I have eliminated this here my contribution to CO2 emissions, what do we do about the 100 companies that cause 70% of global CO2 emissions? Or is that no longer an issue once my car is taken out of circulation?
Transportation is a quarter of global emissions, with passenger vehicles making up half of that number and is only getting larger as more people in the world decide they need a car.
The number you're looking for is 20 companies making up 30% of emissions. They're almost exclusively oil companies, with more than half of them being state owned enterprises. Reduce the need for oil and you reduce the amount they pollute.
So, how do you do that?
Personal vehicles are the most flexible in terms of emissions. Increasing the usability of public transportation has a direct correlation with the number of vehicles on the road. Sure, people out in the middle of nowhere need a vehicle and nobody is looking to take that from them, but you could HALF the number of people in the US with a car if cities had proper public transport or were as walkable as they were barely 80 years ago.
The private sector is more difficult. We'd need to rebuild our train infrastructure that has been gutted and raided by our rail companies in order to get trucks off the interstate. Coincidentally, that would get MORE people off the road since you wouldn't need a car to go between cities.
Additionally, you seem to be under the impression that we're incapable of solving multiple problems at the same time. We can make cars unnecessarily (not GET RID of them) while also cutting emissions in other areas.
Make no mistake, we do need to address other areas, but cars are an easy target that would reduce tons of emissions and increase people's quality of life as well. Cars are a massive waste of space and a huge ongoing drain on taxpayer dollars for very little benefit when you compare it to the alternatives.
I am not saying that we are incapable of solving multiple problems at once, I am saying that we are incapable of solving the main problem.
I was not joking when I said that my car is not a factor. My individual part in this regard is done. But the point remains that by considering the main sources of pollution too "inflexible" to tackle, it seems that we are debating about which colour to best repaint a sinking ship here while being utterly, completely powerless to address the big hole in the hull.
So in conclusion, I'll now pat myself on the back for having done my part while sailing this doomed (but [for some at least] highly profitable) planet to hell in a handbasket.
If we assume that you'll have a car even if they become unnecessary, then sure, you've done all you're willing to do. However there are tens of millions of people that would happily stop driving if it weren't absolutely required to function. They have not finished doing their part. That includes me.
I mean.. they're making things for us generally. I don't think they're emitting recreationally. Look at a pie chart of total emissions and figure what you could cut to hit 50%. Do away with all transportation.. Boats planes etc and you're not even close.
If the average person cut out 100% of their carbon emissions for the rest on their life, they'd save, on average, the amount of CO2 that industry creates in ~1 second. Our personal emissions are but a drop in the ocean in the grand scheme. Change is best brought about by voting both metaphocally with our wallets and literally with our ballot papers.
The industries produces CO2 to provide us goods and services. Car is one of them; not using a car, not only I don't produce gazes directly (or less), but I also don't use something “the industry” produced CO2 for.
