One thing that the carbon neutral concept overlooks is that the world is perfectly capable of absorbing the carbon output of a single person.
For average individuals we are not able to overwhelm the world with our carbon output. There is a carbon cycle and as CO2 increases in the atmosphere, plants grow faster and bring it back to a stable median.
It is massive industrialization that has overwhelmed the capacity of the earth to absorb the excess carbon dioxide created by humankind.
What you should do is spend your money on companies that have embraced carbon neutrality or being carbon negative, purchase items from low carbon companies, and be reasonable and responsible with your use of energy, including fuel and electricity.
When you have opportunities to vote for environmental initiatives, you should vote for them.
While you should be conspicuous of your carbon footprint in the environment that we have, you should also know that your ability to actually fix the issue is practically non-existent. The only thing that is going to fix the issue is government ruling that forces industries to stop polluting the environment at the rate that they are doing even if it causes our economy to decrease.
The only way for such initiatives to ever happen is if the population becomes carbon conscious and pushes for such initiatives. If enough of us do enough then the people in power will move to come towards us and make changes that will help keep them in power.
