Is carbon removal even capable of making a dent? Is it even worth discussing? CO2 is a tiny component of air, meaning that we would have to move vast quantities air through some sort of a filter to get tiny amounts of carbon out (i.e. 1 million particles of air, to filter out 400 of CO2).
- hedora 6y agoWith current technology, it costs between $30-90 per ton to remove CO2 from the atmosphere. A gallon of gas produces 20 pounds of CO2 (most of the weight is from O2 from the atmosphere). A ton is 2000 pounds, so 100 gallons of gas produces a ton of CO2. A $1/gallon (25-33%) carbon recapture tax on gasoline would be enough to make cars carbon negative. Global warming is a political, not technical, problem.
