Possible Energy Saving in the World to Reduce CO₂ Emission and Other Counter Measures

Abstract

This paper describes possible reduction of CO₂ emission from fossil fuels in the world. The reduction in this paper means that from the necessary fossil fuelconsumption in 2005 by saving energy with raising thermal efficiency. By raising thermal efficiency, human kind can possibly save energy in four sectors by about 30%;industry, transportation, electric power generation and consumption, and residential and commercial.
Since reduction of CO₂ emission would also become about 30% in 2005, the total CO₂ emission amount would be as same as that in 1986; the total CO₂ emission amount would be kept almost constant in coming 15 years.
One of the other possible countermeasures would be forestation of the destructed forests or of the dry area. Annual forestation of about 0.4 million km² would make required forest area to absorb CO₂ to reduce CO₂ emission by 50% in 20 years.
