Porn scratches an itch. If it didn't exist the itch would still be there. So the CO2 production of porn should be measured against whatever the alternative is. Wouldn't people spend more time and CO2 producing energy finding mates or other distractions in place of porn? If they do spend more time mating with non virtual partners won't they spawn more CO2 producers than before?
It may be that porn produces lots of CO2 AND it is a net CO2 sink compared to the alternatives. The article mentions no such trade offs.
