Concentration of carbon dioxide in the atmosphere reached 394.97ppm at Mauna Loa in May 2011 — 41% above the 280ppm it had been for thousands of years before the Industrial Revolution started.
Given the dangers of global warming, carbon dioxide should be on the way back to 280ppm. Emission cuts alone will not be able to accomplish this, so what more can be done?
Energy feebates as pictured above can best clean up energy, while other feebates can best raise revenue for carbon dioxide removal.
Energy feebates can phase themselves out, completing the necessary shift to clean energy within a decade. Carbon dioxide removal will need to continue for much longer, so funding will need to be raised from other sources, such as sales of livestock products, nitrogen fertilizers and Portland cement.
