I'll start by conceding on the main point; that is, let's assume an increase in CO2 does indeed result into increased temperature, and let's also assume that the increase in CO2 comes from human activity. Yes, this is contentious to say the least, there a huge debate on data and all that jazz but...just indulge me, and for a second pretend that the science is settled.
From the premise above, it derives the well-known statement that humanity as a whole needs to reduce the amount of CO2 emissions. This means that CO2 emissions become a limited issue resource, something of which only a fixed amount is available every year. The question is: how do you divide up this limited resource among humans?
I think there are three options (I assume there is a mechanism to precisely compute emissions, which might be far-fetched, but it's beside the point here).
- The equal option. You take the total of permitted CO2 emissions, and divide it in equal parts. This means that people who currently emit a lot (think private jet owners), will have to considerably reduce their emissions, and probably lower their living standards. This seems fair and just, after all they are the biggest contributors to the current situation. It's also the application at a lower scale of the accepted principle that developed nations shoudl cut more than developing ones, because they have contributed more to the problem.
Also, sharing CO2 emissions like this allows people who currently emit less to increase their activity and improve their life; this too seems fair and reasonable.
- The equal reduction option. Everyone cuts current emissions by the same percentage, so that the total comes down to the required, permitted amount. This is not as fair as the previous solution. Crued example: if you have a 20-room mansion, and you are asked to cut emissions by 20%, turning off heating in four of your rooms is not a big deal, and won't affect your life much (unless you are used to throw gigantic parties). But if you live in a two-bedroom council house, a similar cut probably means your home will be cold for the whole winter.
- The Market option. In this case, you fix a price for emissions, and let people buy permits to emit according to their needs. Economic theory says that the people who most need emitting will be willing to pay the price.
