[Our title comes with a hat tip from "Babylon 5," where it appeared as a line of dialog]
Someday you will not be able to set off fireworks or shoot a rifle or grill meat on a barbecue -- either at all, or more likely only if you are in conformance with strict new carbon caps.
Smart technology will mean that our personal uses of energy will be monitored. Average Americans already create many tons of carbon dioxide and hydrocarbons just from breathing and excreting but mostly from using technology, like gasoline engines. 
When it becomes clear, as NASA scientist James Hansen has said, that in the near future the planet's ecological survival will depend on drastically reduced carbon emissions, humankind will be forced to do something about it. Voluntary restraints will not work. Market restraints will work to some extent (a carbon tax, for example). 
So what may very well become necessary is a world in which each individual is not only taught and encouraged to live a vital, low-carbon lifestyle, but also a world in which to some extent carbon emissions are tracked right down to the household and personal level.
So if you turn on a light switch, your household will add to its carbon emissions output, consistent with the (hopefully very diminished) amount of carbon your local power provider emits to produce that power. At some point, you may exceed your permitted individual level. Maybe your level will be higher or lower than average, depending on medical need or where, precisely, you live. But you will have a limit. 
And when you exceed it, there will be some kind of penalty. Monetary, ideally, but in a world gone totally haywire it might go beyond that. And then we'd have more people playing posse comitatus games with the government and their neighbors. Hiding their outputs. Flipping the bird as they helped drag down the ecosystem to an eventual heat death.
But it won't just be carbons and hydrocarbons. It'll be thermal emissions. Any engine or electronic device, including your cell phone, that produces heat will be tagged and measured, as well. 
[That, by the way, is why nuclear fission power plants aren't other than a short-term fix. Sure, they put out very few air pollutants, if properly operated and maintained. But -- not even considering radioactive waste storage -- most of these plants use a hammer-to-kill-a-fly approach to produce power, boiling pressurized water to drive turbines. And that creates huge amounts of heat, which has to be taken up by the atmosphere and biosphere.]
Someday we'll probably have enormous sunshades flying in fixed orbit between Earth and Sun, giant Venetian blinds to screen out too  much heat. We'll try other more earth-bound remedies on a global engineering scale. We'll try small solutions, making machines and processes more energy efficient and earth friendly. We'll try to curb consumption in part by encouraging population control. 
But none of it will work unless all of it adds up to too much. And that will stress the cultures of this world. And that will lead to resistance. And that will slow our reforms.
Stay tuned. We've got a long way to go to save the planet so we can save ourselves.
